在ViewScript中显示Zend_Form表单错误

问题描述：

我正在尝试使用ViewScript在表单之前显示所有表单错误.这是我当前试图在ViewScript中使用的代码:

I'm trying to display all form errors before the form using a ViewScript. Here is the code that I'm currently trying to use within my ViewScript:

<div class="errors">
<?php echo $this->formErrors($this->element->getMessages()); ?>
</div>

此呼叫给我一条错误消息:

This call gives me an error message:

警告:htmlspecialchars()期望参数1为字符串，给定数组

Warning: htmlspecialchars() expects parameter 1 to be string, array given

我已经看到相同的代码在其他地方提出了建议，但是对我来说不起作用.如果我打印出$ this-> element-> getMessages()，我会看到以下错误消息:

I've seen this same code suggested other places but its not working for me. If I print out $this->element->getMessages() I do see the error messages as the following:

Array([myField] => Array([isEmpty] =>值是必需的，不能为空))

Array ( [myField] => Array ( [isEmpty] => Value is required and can't be empty ) )

有什么想法吗?

答

getMessages()返回一个由表单元素名称组成的数组作为键，每个键都包含该元素的错误数组.因此，基本上不用交给formErrors视图助手:

The getMessages() returns an array of form element names as keys which each contain an array of errors for that element. So basically instead of handing the formErrors view helper:

Array ( [isEmpty] => Value is required and can't be empty )

您正在处理它:

Array ( [myField] => Array ( [isEmpty] => Value is required and can't be empty ) )

您可能想要执行以下操作:

You would want to do something like this instead:

$arrMessages = $this->myForm->getMessages();
foreach($arrMessages as $field => $arrErrors) {
    echo sprintf(
        '<ul><li>%s</li>%s</ul>',
        $this->myForm->getElement($field)->getLabel(),
        $this->formErrors($arrErrors)

    );
}
