这是我对ctp页面的看法:
<h1>Add Post</h1>
<?php echo $this->form->create(null,array('url'=>array('controller'=>'posts','action'=>'ajaxAdd'),'id'=>'saveForm'));
echo $this->form->input('ajaxtitle');
echo $this->form->input('ajaxbody',array('rows'=>'3'));
echo $this->form->end('Save Post');
?>
<script>
$(document).ready(function(){
$("#saveForm").submit(function(){
var formData = $(this).serialize();
var formUrl = $(this).attr('action');
$.ajax({
type:'POST',
url:formUrl,
data:formData,
success: function(data,textStatus,xhr){
alert(data);
}
});
return false;
});
});
</script>
这是PostsController函数
class PostsController extends AppController
{
public $name = 'Posts';
public $helpers = array('Html', 'Form', 'Session');
public $components = array('RequestHandler');
public function ajaxAdd()
{
$this->autoRender=false;
if($this->RequestHandler->isAjax()){
Configure::write('debug', 0);
}
if(!empty($this->data)){
$inputData = array();
$inputData['Post']['title'] = $this->data['Post']['ajaxtitle'];
$inputData['Post']['body'] = $this->data['Post']['ajaxbody'];
$data = $this->Post->findByTitle($inputData['Post']['title']);
$this->Post->create();
if(empty($data))
{
if($this->Post->save($inputData))
return "success";
}else
{
return "error";
}
}
}
}
与数组作为$inputData在保存，每当我点击提交按钮没有被保存在数据库中。
但是当我在保存函数中传递$this->data时，像id，创建和修改的列被填充，但标题和主体列留空。
My posts database包含id,title,body,created,modified
你可以试试下面的javascript代码
$("#saveForm").submit(function(){
var formData = $(this).serializeArray();
var formUrl = $(this).attr('action');
$.ajax({
type:'POST',
url:formUrl,
data:formData,
success: function(data,textStatus,xhr){
alert(data);
}
});
你没有在ajax请求中发送数组，这就是为什么你没有在$this->data中获得数组。但首先运行这段代码与echo "<pre>";print_r($this->data);在后控制器检查您是否获得数据
如果您使用的是CakePHP 3.0而不是更早的版本，您应该使用$this->request->data()而不是$this->data。
http://book.cakephp.org/3.0/en/controllers/request-response.html request-body-data
如果是这种情况，代码应该如下所示:
public function ajaxAdd()
{
$this->autoRender=false;
if($this->RequestHandler->isAjax()){
Configure::write('debug', 0);
}
if(!empty($this->request->data())){
$inputData = array();
$inputData['Post']['title'] = $this->request->data('Post.ajaxtitle');
$inputData['Post']['body'] = $this->request->data('Post.ajaxbody');
$data = $this->Post->findByTitle($inputData['Post']['title']);
$this->Post->create();
if(empty($data))
{
if($this->Post->save($inputData))
return "success";
}else
{
return "error";
}
}
}
