CakePHP 2.1 Ajax验证错误 [英] CakePHP 2.1 Ajax validation errors
问题描述
我试图获得验证错误与Ajax和jQuery工作在CakePHP 2.1中的联系人窗体。在名称字段模糊时调用js函数:
I'm trying to get validation errors with Ajax and jQuery working in CakePHP 2.1 for a contact form. On blur of the name field a js function is called:
$(document).ready(function(){
$('#name').blur(function(){
$.post(
'/Cake_ajax/Contacts/validate_form',
{ field: $(this).attr('id'), value: $(this).val() },
handleNameValidation
);
});
function handleNameValidation(error){
if(error.length > 0){
if($('#name-notEmpty').length == 0){
$('#name').after($('<div id="name-notEmpty" class="error-message">' + error + '</div>'));
}
}else{
$('#name-notEmpty').remove();
}
}
});
javascript在我的控制器中调用validate_form函数:
The javascript calls the validate_form function in my controller:
public function validate_form(){
if($this->RequestHandler->isAjax()){
$this->request->data['Contact'][$this->request->params['form']['field']] = $this->request->params['form']['value'];
$this->Contact->set($this->request->data);
if($this->Contact->validates()){
$this->autorender = FALSE; // don't render a view
}else{
$error = $this->validateErrors($this->Contact);
$this->set('error', $error[$this->request->params['form']['field']]);
}
}
}
调用错误时会出现一些错误:
In my view I'm getting a couple of errors when the error is called:
Undefined index: form [APP\Controller\ContactsController.php
Undefined index: form [APP\Controller\ContactsController.php
我的智慧结束了,我是CakePHP的新手。任何帮助将非常感谢。
I'm at my wits end, and I'm fairly new to CakePHP. Any help would be greatly appreciated.
推荐答案
在您的控制器中,应该有如下所示。 Cake 2.0替换了RequestHandlerComponent和Controller中的许多功能。它也将所有地方的$ this-> params数组和旧的$ this-> data替换为$ this-> request-> data,就像这样。您可以访问迁移指南。
In your controller you should have something like below. Cake 2.0 replaces many features in RequestHandlerComponent and Controller. It also replaces $this->params array in all places and the old $this->data to $this->request->data, something like that. You can visit the migration guide.
public function validate_form(){
if($this->RequestHandler->isAjax()){
$this->request->data['Contact'][$this->request['form']['field']] = $this->request['form']['value'];
$this->Contact->set($this->request->data);
if($this->Contact->validates()){
$this->autorender = FALSE; // don't render a view
}else{
$error = $this->validateErrors($this->Contact);
// didn't validate logic
$this->set('error',$this->Contact->validationErrors[$this->request['data']['field']][0]);
}
}
}
