Question

我正在尝试通过ajax删除cakephp数据。我已将postlink按钮更改为简单的html按钮，如

<button class="del" id=<?php echo $user['User']['id']; ?>>Delete </delete>

现在，我可以通过以下代码获取用户ID

$('document').ready(function(){
        $('.del').click(function(){
            var x=$(this).attr("id");
            alert(x);
        });
    });

我已成功获取用户的ID。现在我正在尝试将其发送给用户控制器中的删除操作。所以我编码为

$('document').ready(function(){
        $('.del').click(function(){
            var x=$(this).attr("id");
            alert(x);
            jQuery.get("<?php echo $this->webroot . $this->params["users"]; ?>/delete",{"id":x},function(data,stat){
                                 jQuery("#success").load("success.ctp");
            });
        });
    });

现在在控制器的删除操作中我试过了

public function delete($id=NUll) {
        $id=$_GET['id'];
        $this->User->id = $id;
        if ($this->User->delete()) {
            $this->Session->setFlash(__('The user has been deleted.'));
        } 
        return $this->redirect(array('action' => 'index'));
    }

这里它不起作用。在控制器中如何定义它？

Answer 1

如果您在过滤前使用

function beforeFilter()
{
    //Here set Which pages should be accessable to various users
    $adminPages =array('delete');
    $this->Auth->allow($adminPages);

    ...... 
}

允许使用Auth allow执行它。

如果那也正常，请检查AJAX字符串是否正确。使用MANUAL DELETE检查abc.com/Users/delete/id:2只需复制粘贴字符串即可进入jQuery.get()。它是否正确删除？

如果一切正常，请按以下步骤操作：）

public function delete($id=NUll) {
    $id=$_GET['id'];
    $this->User->id = $id;
    if ($this->User->delete()) {
        $this->Session->setFlash(__('The user has been deleted.'));
    } 
    return $this->redirect(array('action' => 'index'));
}

和ajax：

        jQuery.get("<?php echo $this->webroot . $this->params["users"].'/delete/';?>"+x+"",{"id":x},function(data,stat){
                             jQuery("#success").load("success.ctp");
        });

Answer 2

这里错误只是网址，我已经改变了它，现在它正常工作

echo $this->webroot . $this->params["users"]; ?>/delete"

TO

echo Router::url(array('controller'=>'users','action'=>'delete'));?>"

Answer 3

如果您想使用ajax

，请尝试此操作

   public function delete_user() {
        $this->autoRender = false;
        if ($this->request->data) {

        $this->User->id = $this->request->data['id'];
        $update = $this->User->saveField($this->request->data['field'], $this->request->data['value']);
        if ($update) {
            $repsonce['success'] = '1';
            $this->Session->setFlash(__d('User', 'User Deleted successfully'), 'default', array('class' => 'alert alert-success'));
        } else {
            $repsonce['success'] = '0';
        }
    } else {

        $repsonce['success'] = '0';
    }
    echo json_encode($repsonce);
}
