Question

我

 if ($editForm->isValid()) {

继续返回false但我没有收到任何错误消息。

我尝试了以下线程中的所有建议技术，例如我做

var_dump( $editForm->getErrorsAsString() );
die;

并获取

string(266) "name: No errors syncSchema: 1: No errors 12: No errors 37: No errors 38: No errors 49: No errors 14: No errors 39: No errors 76: No errors 152: No errors "

Symfony2 : How to get form validation errors after binding the request to the form

可能导致此行为的其他任何事情？

Answer 1

显然，在构建symfony2.3方式时，你需要在树枝上做这个，

{{ form_start(form) }}
   {{ form_errors(form) }}

   {{ form_row(form.task) }}
   {{ form_row(form.dueDate) }}
{{ form_end(form) }}

尽管如此，对于以老式方式构建的表单，您仍然可以用老式的方式将它们弄清楚。

Answer 2

假设您使用Symfony 2.3，我认为您错过了模板中的form_end()（iirc在2.3之前称为form_rest()）。查看当前的docmentation。因此，不要只是简单地写</form> form_end(edit_form)，而应该使您的表单有效。

Answer 3

考虑一下，你正在验证所显示的一切，没有显示的错误，所以有一些隐藏的东西需要验证：）

{{form_widget（form._token）}}？ csrf检查？

btw form_rest！= form_end

symfony2 isValid（）返回false而没有错误
