/** |
|
* A Bootstrap 3 enhanced version of [[\yii\widgets\ActiveField]]. |
|
* |
|
* This class adds some useful features to [[\yii\widgets\ActiveField|ActiveField]] to render all |
|
* sorts of Bootstrap 3 form fields in different form layouts: |
|
* |
|
* - [[inputTemplate]] is an optional template to render complex inputs, for example input groups |
|
* - [[horizontalCssClasses]] defines the CSS grid classes to add to label, wrapper, error and hint |
|
* in horizontal forms |
|
* - [[inline]]/[[inline()]] is used to render inline [[checkboxList()]] and [[radioList()]] |
|
* - [[enableError]] can be set to `false` to disable to the error |
|
* - [[enableLabel]] can be set to `false` to disable to the label |
|
* - [[label()]] can be used with a `boolean` argument to enable/disable the label |
|
* |
|
* There are also some new placeholders that you can use in the [[template]] configuration: |
|
* |
|
* - `{beginLabel}`: the opening label tag |
|
* - `{labelTitle}`: the label title for use with `{beginLabel}`/`{endLabel}` |
|
* - `{endLabel}`: the closing label tag |
|
* - `{beginWrapper}`: the opening wrapper tag |
|
* - `{endWrapper}`: the closing wrapper tag |
|
* |
|
* The wrapper tag is only used for some layouts and form elements. |
|
* |
|
* Note that some elements use slightly different defaults for [[template]] and other options. |
|
* You may want to override those predefined templates for checkboxes, radio buttons, checkboxLists |
|
* and radioLists in the [[\yii\widgets\ActiveForm::fieldConfig|fieldConfig]] of the |
|
* [[\yii\widgets\ActiveForm]]: |
|
* |
|
* - [[checkboxTemplate]] the template for checkboxes in default layout |
|
* - [[radioTemplate]] the template for radio buttons in default layout |
|
* - [[horizontalCheckboxTemplate]] the template for checkboxes in horizontal layout |
|
* - [[horizontalRadioTemplate]] the template for radio buttons in horizontal layout |
|
* - [[inlineCheckboxListTemplate]] the template for inline checkboxLists |
|
* - [[inlineRadioListTemplate]] the template for inline radioLists |
|
* |
|
* Example: |
|
* |
|
* ```php |
|
* use yii\bootstrap\ActiveForm; |
|
* |
|
* $form = ActiveForm::begin(['layout' => 'horizontal']) |
|
* |
|
* // Form field without label |
|
* echo $form->field($model, 'demo', [ |
|
* 'inputOptions' => [ |
|
* 'placeholder' => $model->getAttributeLabel('demo'), |
|
* ], |
|
* ])->label(false); |
|
* |
|
* // Inline radio list |
|
* echo $form->field($model, 'demo')->inline()->radioList($items); |
|
* |
|
* // Control sizing in horizontal mode |
|
* echo $form->field($model, 'demo', [ |
|
* 'horizontalCssClasses' => [ |
|
* 'wrapper' => 'col-sm-2', |
|
* ] |
|
* ]); |
|
* |
|
* // With 'default' layout you would use 'template' to size a specific field: |
|
* // echo $form->field($model, 'demo', [ |
|
* // 'template' => '{label} <div class="row"><div class="col-sm-4">{input}{error}{hint}</div></div>' |
|
* // ]); |
|
* |
|
* // Input group |
|
* echo $form->field($model, 'demo', [ |
|
* 'inputTemplate' => '<div class="input-group"><span class="input-group-addon">@</span>{input}</div>', |
|
* ]); |
|
* |
|
* ActiveForm::end(); |
|
* ``` |
