Cakephp:验证错误不会出现在数据验证 [英] Cakephp: Validation Errors not appearing in data validation
问题描述
我想使用cakephp模型实现表单验证。这是我的代码段...
I am trying to implement form validation using cakephp models. Here are my code snippets...
模型
// File: /app/models/enquiry.php
class Enquiry extends AppModel {
var $name = "Enquiry";
var $useTable = false;
var $_schema = array(
"name" => array( "type" => "string", "length" => 100 ),
"phone" => array( "type" => "string", "length" => 30 ),
"email" => array( "type" => "string", "length" => 255 )
);
var $validate = array(
'name' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Name is required'
),
'email' => array(
'emailFormat' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Email is required'
),
'emailNeeded' => array(
'rule' => array('email', true),
'required' => true,
'message' => 'Must be a valid email address'
)
)
);
}
控制器操作
// /app/controllers/nodes_controller.php
class NodesController extends AppController {
var $name = "Nodes";
var $uses = array( "Enquiry" );
function enquire() {
if ( $this->data ) {
$this->Enquiry->set( $this->data );
if ( $this->Enquiry->validates() ) {
// .....
} else {
$this->set("errors", $this->Enquiry->invalidFields());
}
}
}
}
查看....
// /app/views/nodes/enquire.ctp
<?php echo $form->create("Node", array("action" => "ask")); ?>
<?php echo $form->input("name", array(
"error" => array( "class" => "error-message" ),
"div" => false,
"label" => "Name",
"size" => "40"
) ); ?>
<?php echo $form->input("email", array(
"error" => array( "class" => "error-message" ),
"div" => false,
"label" => "Email",
"size" => "40"
) ); ?>
<?php echo $form->input("phone", array(
"label" => "Phone No.",
"div" => false,
"size" => "30"
) ); ?>
<?php echo $form->end("Send");?>
我的问题:提交时,表单验证发生, > validates方法返回false,但是验证错误永远不会显示。我已经检查了invalidFields()返回的数组,所有在模型中设置的错误消息都存在,但它们没有显示....
My Problem: On submitting, the form validation occurs, the Model->validates method returns false, but the validation errors never get displayed. I have checked the array returned by invalidFields(), all the error messages I set in the model are there, but they are not getting displayed....
我做错了?
回答
推荐答案
基本上,如果验证查询,公司字段应该使用以下名称:data [Inquiry] [name]而不是data [Node] [name]
Basically if you validating Enquiry, the firm fields should with following names: data[Enquiry][name] instead of data[Node][name].
如果您更改
<?php echo $form->create("Node", array("action" => "ask")); ?>
到
<?php echo $form->create("Enquiry", array("action" => "ask")); ?>
错误应该出现在核心。
如果您的表单在Node和Inquiry字段之间有混合,那么只需将模型名称放在字段名称前面,如下所示:
If your form have mix between Node and Enquiry fields, then just put the name of the Model in front of the field name like this:
<?php echo $form->input("Enquiry.email", array(....));?>
