Symfony2：摆脱“这种形式不应该包含额外的领域” [英] Symfony2: get rid of "This form should not contain extra fields"

问题描述

我已经在表单中添加了第二个提交按钮，现在Symfony2对此抱怨：此表单不应包含额外的字段

I have added a second submit button to my form, now Symfony2 complains about it: "This form should not contain extra fields"

尽管我在（

Although I added this option in the formtype:

public function getDefaultOptions(array $options)
    {
        return array(
            'csrf_protection' => false,
        );
    }

有什么想法？

Any ideas?

推荐答案

你可以肯定有多个提交按钮。确保按钮与其他表单字段不在同一个数组中。

You can most certainly have multiple submit buttons. Make sure the button is not in the same array as the other form fields.

例如，如果您的表单字段的名称 FormType [field_name] ，你不能有 FormType [submit_btn] 作为按钮的名字，你必须选择一个不同的名字。

So, for example, if your form fields have a name FormType[field_name], you can't have FormType[submit_btn] as the name of the button and you must choose a different one.

您的控制器可以根据按下的按钮采取不同的行为。如果您的提交按钮被命名为 submit_1 和 submit_2 ，您可以使用类似于

Your controller can act differently depending on the button pressed. If your submit buttons are named submit_1 and submit_2 you can have something similar to

if($this->getRequest()->request->has('submit_1')) {
    // do stuff
} else {
    // do other stuff
}
