/**
|
|
* CFormInputElement represents form input element.
|
|
*
|
|
* CFormInputElement can represent the following types of form input based on {@link type} property:
|
|
* <ul>
|
|
* <li>text: a normal text input generated using {@link CHtml::activeTextField}</li>
|
|
* <li>hidden: a hidden input generated using {@link CHtml::activeHiddenField}</li>
|
|
* <li>password: a password input generated using {@link CHtml::activePasswordField}</li>
|
|
* <li>textarea: a text area generated using {@link CHtml::activeTextArea}</li>
|
|
* <li>file: a file input generated using {@link CHtml::activeFileField}</li>
|
|
* <li>radio: a radio button generated using {@link CHtml::activeRadioButton}</li>
|
|
* <li>checkbox: a check box generated using {@link CHtml::activeCheckBox}</li>
|
|
* <li>listbox: a list box generated using {@link CHtml::activeListBox}</li>
|
|
* <li>dropdownlist: a drop-down list generated using {@link CHtml::activeDropDownList}</li>
|
|
* <li>checkboxlist: a list of check boxes generated using {@link CHtml::activeCheckBoxList}</li>
|
|
* <li>radiolist: a list of radio buttons generated using {@link CHtml::activeRadioButtonList}</li>
|
|
* <li>url: an HTML5 url input generated using {@link CHtml::activeUrlField}</li>
|
|
* <li>email: an HTML5 email input generated using {@link CHtml::activeEmailField}</li>
|
|
* <li>number: an HTML5 number input generated using {@link CHtml::activeNumberField}</li>
|
|
* <li>range: an HTML5 range input generated using {@link CHtml::activeRangeField}</li>
|
|
* <li>date: an HTML5 date input generated using {@link CHtml::activeDateField}</li>
|
|
* </ul>
|
|
* The {@link type} property can also be a class name or a path alias to the class. In this case,
|
|
* the input is generated using a widget of the specified class. Note, the widget must
|
|
* have a property called "model" which expects a model object, and a property called "attribute"
|
|
* which expects the name of a model attribute.
|
|
*
|
|
* Because CFormElement is an ancestor class of CFormInputElement, a value assigned to a non-existing property will be
|
|
* stored in {@link attributes} which will be passed as HTML attribute values to the {@link CHtml} method
|
|
* generating the input or initial values of the widget properties.
|
|
*
|
|
* @property boolean $required Whether this input is required.
|
|
* @property string $label The label for this input. If the label is not manually set,
|
|
* this method will call {@link CModel::getAttributeLabel} to determine the label.
