Class CHtml

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".

Note, the values and labels will be automatically HTML-encoded by this method. `$htmlOptions` `array` $htmlOptions additional HTML attributes. Besides normal HTML attributes, a few special attributes are recognized. See `CHtml::clientChange()` and `CHtml::tag()` for more details. In addition, the following options are also supported: encode: boolean, specifies whether to encode the values. Defaults to true. prompt: string, specifies the prompt text shown as the first list option. Its value is empty. Note, the prompt text will NOT be HTML-encoded. empty: string, specifies the text corresponding to empty selection. Its value is empty. The 'empty' option can also be an array of value-label pairs. Each pair will be used to render a list option at the beginning. Note, the text label will NOT be HTML-encoded. options: array, specifies additional attributes for each OPTION tag. The array keys must be the option values, and the array values are the extra OPTION tag attributes in the name-value pairs. For example, <pre> array( 'value1'=>array('disabled'=>true,'label'=>'value 1'), 'value2'=>array('label'=>'value 2'), ); </pre> Returns `string` the generated list box See `CHtml::clientChange()` `CHtml::listData()`
`public static string`	# `activeCheckBoxList( CModel $model, string $attribute, array $data, array $htmlOptions = array() )` Generates a check box list for a model attribute. The model attribute value is used as the selection. If the attribute has input error, the input field's CSS class will be appended with `CHtml::$errorCss`. Note that a check box list allows multiple selection, like `CHtml::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. 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 `CHtml::$errorCss`. Note that a check box list allows multiple selection, like `CHtml::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.

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}" will be replaced by the corresponding check box 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. encode: boolean, specifies whether to encode HTML-encode tag attributes and values. Defaults to true. 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. 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 ''. Internally, a hidden field is rendered so when the checkbox is not checked, we can still obtain the value. If 'uncheckValue' is set to NULL, there will be no hidden field rendered. Returns `string` the generated check box list See `CHtml::checkBoxList()`

`public static mixed`	# `value( mixed $model, mixed $attribute, mixed $defaultValue = null )` Evaluates the value of the specified attribute for the given model. The attribute name can be given in a dot syntax. For example, if the attribute is "author.firstName", this method will return the value of "$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']". Evaluates the value of the specified attribute for the given model.

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 `CHtml::listData()`. Please refer to its documentation for more details. Parameters `$model` `mixed` $model the model. This can be either an object or an array. `$attribute` `mixed` $attribute the attribute name (use dot to concatenate multiple attributes) or anonymous function (PHP 5.3+). Remember that functions created by "create_function" are not supported by this method.
