Package system.web.helpers
Inheritance class CHtml
Since 1.0
Source Code framework/web/helpers/CHtml.php
CHtml is a static class that provides a collection of helper methods for creating HTML views.

Nearly all of the methods in this class allow setting additional html attributes for the html tags they generate. You can specify for example. 'class', 'style' or 'id' for an html element. For example when using array('class' => 'my-class', 'target' => '_blank') as htmlOptions it will result in the html attributes rendered like this: class="my-class" target="_blank".

A special option named 'uncheckValue' is available that can be used to specify the value returned when the checkbox is not checked. By default, this value is '0'. Internally, a hidden field is rendered so that when the checkbox is not checked, we can still obtain the posted uncheck value. If 'uncheckValue' is set as NULL, the hidden field will not be rendered.

  • separator: string, specifies the string that separates the generated check boxes.
  • checkAll: string, specifies the label for the "check all" checkbox. If this option is specified, a 'check all' checkbox will be displayed. Clicking on this checkbox will cause all checkboxes checked or unchecked.
  • checkAllLast: boolean, specifies whether the 'check all' checkbox should be displayed at the end of the checkbox list. If this option is not set (default) or is false, the 'check all' checkbox will be displayed at the beginning of the checkbox list.

Since 1.1.7, a special option named 'uncheckValue' is available. It can be used to set the value that will be returned when the checkbox is not checked. By default, this value is ''.

}

Generates a check box list for a model attribute. The model attribute value is used as the selection. If the attribute has input error, the input field's CSS class will be appended with errorCss. Note that a check box list allows multiple selection, like listBox. As a result, the corresponding POST value is an array. In case no selection is made, the corresponding POST value is an empty string.

checkBoxList() method
public static string checkBoxList(string $name, mixed $select, array $data, array $htmlOptions=array ( ))
$name string name of the check box list. You can use this name to retrieve the selected value(s) once the form is submitted.
$select mixed selection of the check boxes. This can be either a string for single selection or an array for multiple selections.
$data array value-label pairs used to generate the check box list. Note, the values will be automatically HTML-encoded, while the labels will not.
$htmlOptions array additional HTML options. The options will be applied to each checkbox input. The following special options are recognized:
  • template: string, specifies how each checkbox is rendered. Defaults to "{input} {label}", where "{input}" will be replaced by the generated check box input tag while "{label}" be replaced by the corresponding check box label, {beginLabel} will be replaced by <label> with labelOptions, {labelTitle} will be replaced by the corresponding check box label title and {endLabel} will be replaced by </label>
  • separator: string, specifies the string that separates the generated check boxes.
  • checkAll: string, specifies the label for the "check all" checkbox. If this option is specified, a 'check all' checkbox will be displayed. Clicking on this checkbox will cause all checkboxes checked or unchecked.
  • checkAllLast: boolean, specifies whether the 'check all' checkbox should be displayed at the end of the checkbox list. If this option is not set (default) or is false, the 'check all' checkbox will be displayed at the beginning of the checkbox list.
  • labelOptions: array, specifies the additional HTML attributes to be rendered for every label tag in the list.
  • container: string, specifies the checkboxes enclosing tag. Defaults to 'span'. If the value is an empty string, no enclosing tag will be generated
  • baseID: string, specifies the base ID prefix to be used for checkboxes in the list. This option is available since version 1.1.13.

protected static void clientChange(string $event, array &$htmlOptions)

If there is no parent form the data listed in 'params' will be submitted instead (via POST method), to the URL in 'submit' or the currently requested URL if 'submit' is empty. Please note that if the 'csrf' setting is true, the CSRF token will be included in the params too.
  • params: array, name-value pairs that should be submitted together with the form. This is only used when 'submit' option is specified.
  • csrf: boolean, whether a CSRF token should be automatically included in 'params' when CHttpRequest::enableCsrfValidation is true. Defaults to false. You may want to set this to be true if there is no enclosing form around this element. This option is meaningful only when 'submit' option is set.
  • return: boolean, the return value of the javascript. Defaults to false, meaning that the execution of javascript would not cause the default behavior of the event.
  • confirm: string, specifies the message that should show in a pop-up confirmation dialog.
  • ajax: array, specifies the AJAX options (see ajax).
  • live: boolean, whether the event handler should be delegated or directly bound. If not set, liveEvents will be used. This option has been available since version 1.1.11.
This parameter has been available since version 1.1.1.

    	 'value2'=>array('label'=>'value 2'),
     );

If the input parameter is an array, it is treated as a controller route and a list of GET parameters, and the CController::createUrl method will be invoked to create a URL. In this case, the first array element refers to the controller route, and the rest key-value pairs refer to the additional GET parameters for the URL.

        return 
call_user_func($attribute,$model);

    return 
$model;
}

Evaluates the value of the specified attribute for the given model. The attribute name can be given in a dot syntax. For example, if the attribute is "author.firstName", this method will return the value of "$model->author->firstName". A default value (passed as the last parameter) will be returned if the attribute does not exist or is broken in the middle (e.g. $model->author is null). The model can be either an object or an array. If the latter, the attribute is treated as a key of the array. For the example of "author.firstName", if would mean the array value "$model['author']['firstName']".

Anonymous function could also be used for attribute calculation since 1.1.13 ($attribute parameter; PHP 5.3+ only) as follows:

$taskClosedSecondsAgo=CHtml::value($closedTask,function($model) {
	return time()-$model->closed_at;
});
Your anonymous function should receive one argument, which is the model, the current value is calculated from. This feature could be used together with the listData. Please refer to its documentation for more details.
