Question

以下是将生成的控制器的代码：

如果未提及则输入工作代码的表格。
生成用于在工作卡中输入值的表单（如果存在工作代码）。
提交2中提到的表格后，将Jobcard生成为PDF。

问题：第一次提交表单（在2中提到）时，控制器将按预期工作。但是问题从那以后开始。上述提交的表格如下：

$ form_jobcard-> isSubmitted（）为true。
$ form_jobcard-> isValid（）为假。

Answer 1

始终将实体提供给createFormBuilder

$job = new Job();
$form = $this->createFormBuilder($job)
        // You code
        ->getForm();

检查：https://symfony.com/doc/current/forms.html#building-the-form

$ form-> isValid（）在Symfony3.4中首次提交后始终返回false
