Cakephp form input options youth
The FormHelper does most of the heavy lifting in form creation. The FormHelper focuses on creating forms quickly, in input way that will streamline validation, re-population and layout. The FormHelper is also flexible - it will do almost everything for you using conventions, or you can use specific methods to get only what you need. This method outputs an opening form tag. All parameters are optional. If create is called with no parameters supplied, it assumes you are building a form that submits to the current controller, via the current URL. The default method for form submission is POST. Youth you were to call create inside the view for UsersController:: Once a form has been created with a context, all controls you create will use the active context. In the case of an ORM backed form, FormHelper can access associated data, validation errors and schema metadata. You can close the active context using the end method, or by calling create again. This will POST the form data to the add action of ArticlesController. However, you can also use the same logic to create an edit form. The FormHelper uses the Entity object to automatically detect whether to create an add or edit form. For example, if we browse to http: Since youth is an edit form, a hidden input field is generated to override the default HTTP method. This special array can contain a number of different key-value pairs that affect the way the form tag is generated. If however, you are building a form that needs to read from the query string, you can use valueSource to change where FormHelper reads data input data from:. The input sources are contextdata and query. You can use one or more sources. Any widgets generated by FormHelper will gather their values from the sources, in the order you setup. The value sources will be reset to the default ['context'] when end is called. By using the type option you can change the HTTP method a form will use:. This is to be used if there are any file elements inside the form. The absence of the proper enctype attribute will cause the file uploads not to function. This allows CakePHP to emulate proper REST support in web browsers. Using the 'url' option allows you to point the form to a specific action in your current controller or another controller in your application. The supplied URL can be relative to your CakePHP application:. Often models will have multiple validation sets, and you will want FormHelper to mark fields required based on a the specific validation rules your controller action is going to apply. For example, your Users table has specific validation rules that only apply when an account is being registered:. The above will use the rules defined in the register validator, which are defined by UsersTable:: If you are creating a form for associated entities, you can define validation rules for each association by using an array:. Once you have implemented this interface you can wire your new context into the FormHelper. It is often best to do this in a View. Context factory functions are where you can add logic for checking the form options for the correct type of entity. If matching input data is found you can return an object. If there is no match return null. The control method lets you to generate complete form controls. These controls will include a wrapping divlabelcontrol widget, and validation error form necessary. By using the metadata in the form context, this method will choose an appropriate control type for each field. Internally control uses the other methods of FormHelper. By default the control method will employ the following widget templates:. The type of control created when we provide no additional options to specify the generated element type is inferred via model introspection and depends on the column datatype:. As a small subtlety, generating specific elements via the control form method will always also generate the wrapping divby default. Generating the same type of element via one of the specific form methods e. Depending on your needs you can use one or another. You can disable automatic required flagging using the 'required' option:. You can use the control method of the FormHelper to create appropriate controls for all of these form fields:. Besides the specific Options for Controlyou also can specify any option accepted by corresponding cakephp method for the chosen or inferred by CakePHP control type and any HTML attribute for instance onfocus. If you want to create a select form field while using a belongsTo or hasOne relation, you can add the following to your UsersController assuming your User belongsTo Group:. To make a select box for a belongsToMany Groups association you can add the following to your UsersController:. If your model name consists of two or more words e. You should not use FormHelper:: You can create controls for associated models, or arbitrary models by passing in association. Any dots in your field names will be converted into nested request data. For example, if you created a field with a name 0. This convention makes it easy to save data with the ORM. Details for the various association types can be found in the Creating Inputs for Associated Data section. When creating datetime related controls, FormHelper will append a field-suffix. You may notice additional fields named yearmonthdayhourminuteor meridian being added. These fields will be automatically converted into DateTime objects when entities are marshalled. This subsection will cover the options specific to FormHelper:: In addition to the field types found in the Creating Form Controlsyou can also create 'file''password'and any other type supported by HTML5. By specifying a 'type' you will force the type of the generated control, overriding model introspection. You can set this key to the string you would like to be displayed within the label that usually accompanies the input HTML element. Alternatively, set this key to false to disable the generation of the label element. Set this to an array to provide additional options for the label element. If you cakephp this, you can use a 'text' key in the array to customize the label text. To override the model error messages use an array with the keys matching the original validation error messages. As seen above you can set the error message for each validation rule you have in your models. In addition you can provide i18n messages for your forms. Controls whether the input element is generated inside or outside the label element. When control generates a checkbox or a radio button, you can set this to false to force the generation of the HTML input element outside of the label element. On the other hand you can set this to true for any control type to force the generated input element inside the label. If you change this for radio buttons then you need to also modify the default radioWrapper template. Depending on the generated control type it defaults to true or false. Any specified templates will be merged on top of the already loaded templates. In addition to the generic control method, FormHelper has specific methods for generating a number of different types of controls. All of these options are also supported by the control method. To reduce repetition, the common options shared by all control methods are as follows:. This will override the 'idPrefix' that may be set. The value is used options the data passed to the form does not contain a value for the field or if no data is passed at all. An explicit default value will override any default values defined in the schema. Beware of using false to assign a youth value. If you want to set a field to not render its value fetched from context or valuesSource you will need to set 'value' to '' instead of setting it to null. In addition to the above options, you can mixin any HTML attribute you wish to use. Any non-special option name will be treated as an HTML attribute, and applied to the generated HTML control element. Changed in version 3. You can disable this behavior by setting the schemaDefault option to false. The rest of the methods available in the FormHelper are for creating specific form elements. In this case, however, this parameter is used primarily to specify HTML tag attributes such as the value or DOM id of an element in the form. Creates a simple input HTML element of input type. Creates a simple input element of password type. If the form is being edited i. In addition to the Common Options For Specific Controlstextarea supports a couple of specific options:. These controls share some commonalities and a few options and thus, they are all grouped in this subsection for easier reference. For options, it sets the HTML 'value' attribute assigned to the input element to whatever you provide as value. For radio buttons or select pickers it defines which element will be selected when the form is rendered in this case 'value' must be assigned a valid, existent element value. May also be used in combination with any select-type control, such as date youth, timedateTime:. The 'value' key for date and dateTime controls may also have as value a UNIX timestamp, or a DateTime object. For a select control where you set the 'multiple' attribute to trueyou can provide an array with the values you want to select by default:. When passed to radio and set to true it will create an extra input element as the first radio button, with a value of '' and a label caption equal to the string 'empty'. If you want to control the label caption set this option to a string instead. When passed to a select method, this creates a blank HTML option element with an empty value in your drop down list. If you want to have an empty value with text displayed instead of just a blank optionpass a string to 'empty':. For checkboxes its value defaults to 0 and for radio buttons to ''. This can be disabled by setting 'hiddenField' to false:. If you want to create multiple blocks of controls on a form, that are all grouped together, you should set this parameter to false on all controls except the first. In this example, only the tertiary colors would be passed, and the primary colors would be overridden:. Form 'hiddenField' on the second control group would prevent this behavior. Creates a checkbox form element. The widget template used is:. This method also generates an associated hidden form input element to force the submission of data for the specified field. However, if you need to put custom attributes on your radio buttons you can use an expanded format. By default select uses the following widget templates:. If you would like to generate a select with optgroups, just pass data in hierarchical format nested array. This works on multiple checkboxes and radio buttons too, but instead of optgroup it wraps the elements in fieldset elements. To generate HTML attributes within an option tag:. Alternatively, set 'multiple' to 'checkbox' in order to output a list of related checkboxes:. To disable all items set 'disabled' to true. To disable only certain items, assign to 'disabled' an array containing the keys of the items to be disabled. This option also works when 'multiple' is set to 'checkbox':. So start off with a input method such as the following:. Each time the form is displayed, the value inside will be empty. Upon submission, file fields provide an expanded data array to the script receiving the form data. This array is generated by PHP itself, so for more detail cakephp the way PHP handles data passed via form fields read the PHP manual section on file uploads. The date and time related methods share a number of common traits and options and hence are grouped together into this subsection. These options are concerning the date-related methods - i. These options are concerning the time-related methods - hourminuteseconddateTime and options. Creates a set of select elements for date and time. By default the dateWidget template is:. Calling the method without additional options will generate, by default, 5 select pickers, for: Creates, by default, three select pickers populated with values for: You can further control the generated select elements by providing additional options. Creates, by default, two select elements hour and minute populated with values for 24 hours and 60 minutes, respectively. For example, to create a time range with minutes selectable in 15 minute increments, and to apply classes to the select boxes, you could do the following:. Creates a select element populated with month names. You can pass in, your own array of months to be used by setting the 'monthNames' attribute, or have months displayed as numbers by passing false. Creates a select element populated with the numerical days of the month. To create an empty option element with a prompt text of your choosing e. Creates a select element populated with the hours of the input. You can create either 12 or 24 hour pickers using the 'format' option:. Creates a select element populated with values for the minutes of the hour. You can create a select picker that only contains specific values by using the 'interval' option. This is useful when the hour format is set to 12 instead of 24as it allows to specify the period of the day to which the hour belongs. Creates a label element. FormHelper exposes a couple of methods that allow us to easily check for field errors and when necessary display customized error messages. The 'errorList' and 'errorItem' templates are used to format mutiple error messages per field. If you would click the Submit button of your form without providing a value for the Ticket field, your form would output:. If you use a certain model field to generate multiple form fields via controland you want the same validation error message displayed for each one, you will probably be better off defining a custom error message inside the respective validator rules. You can pass a relative or absolute URL of an image to the caption parameter instead of the caption text:. Submit inputs are useful when you only need basic text or images. If you need more complex button content you should use button. Creates an HTML button with the specified title and a default type of 'button'. Example of use of the 'escape' form. The end method closes and completes a form. Also, by default, it generates hidden input fields for the SecurityComponent. Since this method generates a form element, do not use this method in an already opened form. Creates an HTML link, but accesses the URL using the method you specify defaults to POST. Requires JavaScript to be enabled in browser. If you want to use this method inside of an existing form, you must use the block option so that the new form is being set to a view block that can be rendered outside of the main form. Be careful to not put a postLink inside an open form. Options use the block option to buffer the form into a view block. Like many helpers in CakePHP, FormHelper uses string templates to format the HTML it creates. While the default templates are intended to be a reasonable set of defaults, you may need to customize the templates to suit your application. To change the templates when the helper is loaded you can set the 'templates' option when including the helper in your controller:. This file should contain an array of templates indexed by name:. Any templates you define will replace the default ones included in the helper. Templates that are not replaced, will continue to use the default values. You can also change the templates at runtime using the setTemplates method:. The reason is that internally templates are compiled to be used with sprintf. The list of default templates, their default format and the variables they expect can be found at the FormHelper API documentation. In addition to these templates, the control method will attempt to use distinct templates for each control container. For example, when creating a datetime control the datetimeContainer will be used if it form present. If that container is missing the inputContainer template will be used. Similar to controlling containers, the control method will also attempt to use distinct templates for each form group. A form group is a combo of label and control. For example, when creating a radio control the radioFormGroup will be used if it is present. You can add additional template placeholders options custom templates, and populate input placeholders when generating controls. New in version 3. The templateVars option was added in 3. By default CakePHP nests checkboxes created via control and radio buttons created by both control and radio within label elements. This helps make it easier to integrate popular CSS frameworks. Generates a set of controls for cakephp given context wrapped in a fieldset. You can specify the generated fields by including them:. If you disable the fieldsetthe legend will not print. Assuming the following table relations:. If we were editing an article with its associations loaded we could create the following controls:. The above controls could then be marshalled into a completed entity graph using the following code in your controller:. CakePHP makes it easy to add custom control widgets in your options, and use them like any other control type. All of the core control types are implemented as widgets, which means you can override any core widget with your own implementation as well. Widget classes have a very simple required interface. The render method expects an array of data to build the widget and is expected to return a string of HTML for the widget. The secureFields method expects an array cakephp data as well and is expected to return an array containing the list of fields to secure for this widget. If we wanted to build an Autocomplete widget you youth do the following:. Obviously, this is a very simple example, but it demonstrates how a custom widget could be built. For more information on string templates, see Customizing the Templates FormHelper Uses. You can load custom widgets when loading FormHelper or by using the addWidget method. When loading FormHelper, widgets are defined as a setting:. If your widget requires other widgets, you can have FormHelper populate those dependencies by declaring them:. In the above example, the autocomplete widget would depend on the text and label widgets. When the autocomplete widget is created, it will be passed the widget objects that are related to the text and label names. To add widgets using the addWidget method would look like:. This will create the custom widget with a label and wrapping div just like controls always does. Alternatively, you can create just the control widget using the magic method:. Unlocks a field making it exempt from the SecurityComponent field hashing. This also allows the fields to be manipulated by JavaScript. Generates a hidden input field with a security hash based on the fields used in the form or an empty string when secured forms are not in use. This is especially useful to set HTML5 attributes like 'form'. Last updated on Jul 02, Created using Sphinx 1. Note Since this is an edit form, a hidden input field is generated to override the default HTTP method. If no type is provided then it will be autodetected based on the form context. Can be a string or a URL array. Any templates provided will be merged on top of the already loaded templates. For example the EntityContext youth a 'table' option that allows you to set the specific Table class the form should be based on. For example, your Users table has specific validation rules that only apply when an account is being registered: Tip As a small subtlety, generating specific elements via the control form method will always also generate the wrapping divby default. Note You should not use FormHelper:: To reduce repetition, the common options shared by all cakephp methods are as follows: Note If you want to set a field to not render its value fetched from context or valuesSource you will need to set 'value' to '' instead of setting it to null. Creates a hidden form input. Creates a textarea control field. The default widget template used is: May also be used in combination with any select-type control, such as datetimedateTime: Note The 'value' key for date and dateTime controls may also have as value a UNIX timestamp, or a DateTime object. The widget template used is: Can also contain youth and HTML attributes. When this array is missing, the method will either generate only the hidden input if 'hiddenField' is true or no element at all if 'hiddenField' is false. Creates a set of radio button inputs. The default widget templates used are: This will provide the name attribute of the select element. When this array is missing, the method will generate only the empty select HTML element without any option elements inside it. By default select uses the following widget templates: Creates a file upload field in the form. The widget template used by default is: If a string, that string is displayed as the empty element. If no default is provided time will be used. By setting any of these options to false you can disable the generation of that specific that select picker if by default it would be rendered in the used method. In addition each option allows you to pass HTML attributes to that specific select element. If set to an array e. Possible values are 'asc' and 'desc'. The time format to use in the select picker; either 12 or When this option is set to anything else than 24 the format will be automatically set to 12 and the meridian select picker will options displayed automatically input the right of the seconds select picker. The time format to use; either 12 or Set to true to enable the seconds drop down. By default the dateWidget template is: For example, to create a time range with minutes selectable in 15 minute increments, and to apply classes to the select boxes, you could do the following: For example, to create a year range from to the current year you would do the following: You can create either 12 or 24 hour pickers using the 'format' option: For example, if you wanted 10 minutes increments you would do the following: String or an array containing any of the Common Options For Specific Controls as well as any valid HTML attributes. A string or array providing cakephp error message s. Uses the following template widgets: Tip If you use a certain model field to generate multiple form fields via controland you want the same validation error message displayed for each one, you will probably be better off defining a custom form message inside the respective validator rules. By default it will use the following widget templates: This is the default type. Allows you to provide secure attributes which will be passed as HTML attributes into the hidden input elements generated for the SecurityComponent. By default not HTML encoded. Also, the postButton method will accept the options which are valid for the button method. String or array which contains the URL of the form Cake-relative or external URL starting with http: Also, the postLink method will accept the options which are valid for the link method. Note Be careful to not put a postLink inside an open form. To change the templates when the helper is loaded you can set the 'templates' option when including the helper in your controller: Allows setting custom types, labels and other options for each specified field. An array of options. If empty, the fieldset will be enabled. Can also be an array of parameters to be applied as HTML attributes to the fieldset tag. Set this to false to disable the legend for the generated form set. You can specify the generated fields by including them: An array of customizations for the fields that will be generated. Allows setting custom types, labels and other options. Can also be an array of parameters to be applied as HTMl attributes to the fieldset tag. Set this to false to disable the legend for the generated control set. Assuming the following table relations: Authors HasOne Profiles Authors HasMany Articles Articles HasMany Comments Articles BelongsTo Authors Articles BelongsToMany Tags If we were editing an article with its associations loaded we could create the following controls: Profiles''Tags''Comments' ] ]. If we wanted to build an Autocomplete widget you could do the following: When loading FormHelper, widgets are defined as a setting: The dot-separated name for the field.
