在 Zend 表单上禁用 Inarray Validator

Question

在添加两个下拉菜单之前，我的表单一直有效。从那时起，在提交表格时我收到错误：

haystack option is mandatory

这是我的 ProjectForm.php

我想我需要通过添加 disable_inarray_validator' => true 来禁用 inarray_validator，但我不确定在哪里添加它。

Answer 1

我建议您传递一个空字符串作为唯一值选项。在您的 javascript 中，您刷新 select 的 <option> 标签以摆脱这个空选项。此外，您还必须通过添加 :

来禁用 Select 元素的默认验证器

$projectWorkflowDropDown->setOptions(array('disable_inarray_validator' => true));

或者

$projectWorkflowDropDown->setDisableInArrayValidator(true);

如果你不添加这个选项，当提交表单时，Zend Form 会告诉你发送的值不在构建表单时提供的 haystack 中。这是一个安全过程，在很多情况下都非常有用，只是在您的情况下不是。

Answer 2

由于我使用的 Zend 版本，我必须在验证表单之前将其添加到控制器：

// Make certain to merge the files info!
$post = array_merge_recursive($request->getPost()->toArray(), $request->getFiles()->toArray());

//Deals with validation of dynamic form 
$projectType = $projectTypes[$post["project_types"]]; 
$form->get('project_workflow_types')->setValueOptions($workflowTypes[$projectType]); 


// set the form instance's data
$form->setData($post);
