我不知道为什么，但我记得当你有一个 symfony 表单且未渲染必填字段时，
isValid我的意思是它只检查小部件在您使用它时是否有值。在我当前的项目中似乎这是错误的。
是否有设置或允许执行此操作？

编辑2：
问题是：比所需的DEMANDE_DTDEM字段正常，引发必填表单字段错误，而他还没有被渲染？
表单字段不应该只在使用时才验证吗？
是的，这是正常行为。字段验证与渲染无关。 如果您不想渲染小部件，则必须显式删除小部件和验证器（使用未设置或 useFields）。
如果您定义了一个小部件和一个验证器（如您的情况），但您不调用
$form['DTDEM']->render()您了解这一点非常重要。在这种情况下，该字段是必需的，然后变成该错误，但如果不是必需的，
$form->save()切勿让小部件处于未渲染状态。你应该在调试时做一些 echo
$formconfigure()我想对glerendegui的答案进行补充。
他所说的在一般情况下都是正确的。但是，游戏规则正在改变。表单的选项filter_extra_fields(false) 显着改变了规则。这就是我最初的误解的原因。
因为将此选项设置为 false，当您的小部件尚未渲染时，$form->save() 不会在您的对象中设置空值。
这是一个重要的补充，因为在我继承的所有遗留代码中，此选项的使用很常见，并且没有受到挑战。
