CakePHP Ajax搜索：为分页显示两次相同的数据

Question

这里ajax搜索工作正常，但问题是相同的数据显示两次，因为我已经给出了分页限制2.如果我使它3，同样的结果显示3次。

这是我的index.ctp

$( "#search" ).keyup(function() {

    var value=$('#search').val();   

        $.get("<?php echo   Router::url(array('controller'=>'userTypes','action'=>'search'));?>",{search:value},function(data){
        $('.search_data').html(data);
     });
})

这是我的搜索操作

public function search()
    {
        $search=$_GET['search'];
        $request=$this->UserType->find('all', array(
        'conditions' => array('UserType.name LIKE' => "%$search%")
        ));
        $this->set('usertype',$request);
    }

这是search.ctp

<?php foreach($usertype as $usertypes) { ?>
    <tr>
            <td><?php echo $usertypes['UserType']['id']; ?></td>
            <td><?php echo $usertypes['UserType']['name']; ?></td>
            <td><?php echo $usertypes['UserType']['description']; ?></td>

    </tr>
<?php } ?>

分页限制在appcontroller中

 parent::beforeFilter();
            $this->Paginator->settings = array(
              'limit'=>2
        );

结果显示我这样

愿任何人帮助我解决它吗？

Answer 1

如果您想使用分页，您的搜索方法应如下所示：

public function search()
{
    if(isset($this->request->query['search'])){
       $search = $this->request->query['search'];
    }else{
       $search = '';
    )
    $this->Paginator->settings = array(
        'conditions' => array('UserType.name LIKE' => "%$search%"),
        'limit' => 2
    );
    ));
    $this->set('usertype',$this->Paginator->paginate());
}
