Yii框架 - 没有回声的beginWidget

Question

I use this code to create my form:

$form=$controller->beginWidget('CActiveForm', array(
            'id'=>'my-form',
            'enableAjaxValidation'=>false
    ));

When I do this, it prints the form. But I want to put this in a variable, because the entire form is returned as string in the method. How can I do this?

Answer 1

The following takes the output buffer, stores it into a variable and then erases it. Enjoy!!!

ob_start();

$form=$controller->beginWidget('CActiveForm', array(
        'id'=>'my-form',
        'enableAjaxValidation'=>false
    ));

$formToStore =  ob_get_clean();
