我有一个表单，直到我添加了两个下拉菜单。从那以后，在提交表格后我得到了错误：
haystack选项是必需的
这是我的ProjectForm.php
$.trim( $(this).text() ) == $.trim( searchString )我想我需要通过添加<?php

来停用inarray_validator，但我不确定在哪里添加它。
答案 0 :(得分：0)
我建议你传递一个空字符串作为唯一的valueOption。在你的javascript中，你刷新select的<option>标签以摆脱这个空选项。
此外，您还必须通过添加：
$projectWorkflowDropDown->setOptions(array('disable_inarray_validator' => true));
或者
$projectWorkflowDropDown->setDisableInArrayValidator(true);
如果您不添加此选项，则在提交表单时，Zend Form将告诉您在构建表单时提供的值不在haystack中。这是一个安全过程，在许多情况下非常有用，而不是在你的。

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);
