Yii framework 2.0是否提供任何视图助手，可以生成带有输入文本字段作为最后选项的复选框列表？

Question

To generate a checkboxlist within Yii framework 2.0 I use the following line of code.

Html::checkboxList($model->choises, null, $arrayOption, ['separator' => '<br />',]);

I would like to have the last checkbox option with an input text field like others. Does Yii framework 2.0 provide any view helper to generate that?

Answer 1

Since I needed to approach this goal I have tried different solution and came up with an ideal solution which I would like to share here since no one yet could answer this question. The solution is for both radionList and checkboxList.

Just inject the $arrayOption with the following code snippet.

$arrayOption[0] = 'Others <input type="text" class="my-class-name" name="MyModel[my_other_option]">';

Add the following code into the rules function inside of the model class.

[
    ['my_other_option',], 'required' , 'when' => function($model) {
                return $model->choises == '0';
    },
],

By doing so, the validation will be failed when you selected the Other option but didn't fill in the input text field, named my_other_option.
