在表单中设置默认值 [英] set a default value in a form

问题描述

我想在表单中默认设置一个值.

I would like set a value by default in my form.

我正在这样做，但没有用:

I am doing this, but didn't work:

$builder->add('points', 'hidden', array(
            'data' => 5000));

任何想法

推荐答案

如果你想默认设置一些东西，就在模型对象上设置:

If you want to set something by default, set it right on the model object:

$model = new Model;
$model->setPoints(5000);

$form = $this->createForm('type', $model);

或者更好的是，如果有意义，将其设置为模型的属性或构造函数:

Or better yet, if it makes sense, set it right to the model's property or the constructor:

class Model 
{
    private $points = 5000;

    // or
    public function __construct()
    {
        $this->points = 5000;
    }
}
