Question

在我的搜索中有四个过滤器。获取搜索结果后，如何使用搜索字词进行分页？这意味着如果我去第二页分页搜索文件管理器表单数据不会出现并显示以下错误

Notice (8): Undefined index: to [APP/Controller/Admin/ScheduleController.php, line 257]

控制器代码

public function search() {

            $this->viewBuilder()->template('allschedule');

            $scheduleto = date('Y-m-d', strtotime($this->request->data['to']." +1 days"));
            $schedulefrom =date('Y-m-d', strtotime($this->request->data['from']));

            if($this->request->data['company'] != 'all' && $this->request->data['gig'] == 'all')
            {
                $searchfilter = array(
                        'Schedule.shift_from > ' => $schedulefrom,
                        'Schedule.shift_from < ' => $scheduleto,
                        'Job.company' =>$this->request->data['company'],
                        'Schedule.status !=' =>0,
                        );
            }
            elseif($this->request->data['company'] == 'all' && $this->request->data['gig'] != 'all')
            {
                $searchfilter = array(
                        'Schedule.shift_from > ' => $schedulefrom,
                        'Schedule.shift_from < ' => $scheduleto,
                        'Schedule.gig_id' =>$this->request->data['gig'],
                        'Schedule.status !=' =>0,
                        );

            }
            elseif($this->request->data['company'] != 'all' && $this->request->data['gig'] != 'all')
            {
                $searchfilter = array(
                        'Job.company' =>$this->request->data['company'],
                        'Schedule.gig_id' =>$this->request->data['gig'],
                        'Schedule.shift_from > ' => $schedulefrom,
                        'Schedule.shift_from < ' => $scheduleto,
                        'Schedule.status !=' =>0,
                        );

             }
            else
            {
                $searchfilter = array(
                        'Schedule.shift_from > ' => $schedulefrom,
                        'Schedule.shift_from < ' => $scheduleto,
                        'Schedule.status !=' =>0,
                        );

            }


        $this->paginate = [
            'fields' => ['User.name', 'Schedule.shift_from', 'Schedule.id', 'Schedule.shift_to', 'Schedule.shift_description', 'Schedule.checkin', 'Schedule.checkout', 'Schedule.start', 'Schedule.stop', 'Schedule.comment', 'Schedule.attested'],
            'conditions' => $searchfilter,
            'contain' => ['Job','User'],
            'order' => [
                'shift_from' => 'ASC'
            ],
            'limit' => 30  //'limit' 
        ];
        $schedules = $this->paginate($this->Schedule);

            $this->set(compact('schedules'));
            $this->set('_serialize', ['schedules']);

    }

CTP文件

<div class="pagination pagination-large">
                <ul>
                        <?php
                            echo $this->Paginator->prev(__('prev'), array('tag' => 'li'), null, array('tag' => 'li','class' => 'disabled','disabledTag' => 'a'));
                            echo $this->Paginator->numbers(array('separator' => '','currentTag' => 'a', 'currentClass' => 'active','tag' => 'li','first' => 1));
                            echo $this->Paginator->next(__('next'), array('tag' => 'li','currentClass' => 'disabled'), null, array('tag' => 'li','class' => 'disabled','disabledTag' => 'a'));
                        ?>
                    </ul>
                </div>

上面的代码生成了分页，但是当它在分页结果中转到下一页时，搜索POST数据丢失，数据列表显示错误。

如何使用过滤器获取分页结果列表？

Filer表格

<?php echo $this->Form->create('Schedule', array('type' => 'post', 'action' => 'search', 'class'=> 'form-inline'));?>
    <div class="form-group">
             <div class="form-group" style="padding: 0 0;">
      <span style="font-size:12px; display: block;">Company</span>
      <?php

                            echo $this->Form->select('company', $companyarray, array('id' => 'company','escape' => false,'class'=> 'form-control input-sm', 'style'=>'width:160px'));
                        ?>
    </div>
    <div class="form-group" id="gigselect" style="padding: 0 10px;">
       <span style="font-size:12px; display: block;">Gig</span>

                            echo $this->Form->select('gig', $searchgigarray, array('id' => 'gig','escape' => false,'class'=> 'form-control input-sm','style'=>'width:160px'));
                        ?>

        </div>
    </div>
  </div>
  <?php echo $this->Form->end() ?>

Answer 1

提交表单时未发生错误的原因是服务器中存在$_POST变量但如果您点击页面按钮IE <a href="search?page=2">2</a>，$_POST将会消失

发生这种情况的原因

注意（8）：未定义的索引：到[APP / Controller / Admin / ScheduleController.php，第257行]

修正将您的方法更改为GET

<?php echo $this->Form->create('Schedule', array('type' => 'get', 'action' => 'search', 'class'=> 'form-inline'));?>
<div class="form-group">
         <div class="form-group" style="padding: 0 0;">
  <span style="font-size:12px; display: block;">Company</span>
  <?php

                        echo $this->Form->select('company', $companyarray, array('id' => 'company','escape' => false,'class'=> 'form-control input-sm', 'style'=>'width:160px'));
                    ?>
</div>
<div class="form-group" id="gigselect" style="padding: 0 10px;">
   <span style="font-size:12px; display: block;">Gig</span>
  <?php

                        echo $this->Form->select('gig', $searchgigarray, array('id' => 'gig','escape' => false,'class'=> 'form-control input-sm','style'=>'width:160px'));
                    ?>
</div>


<div class="form-group" style="padding: 0 0;">
<span style="font-size:12px; display: block;">From</span>
<div class="input-group">
        <span class="input-group-addon"><i class="fa fa-calendar"></i></span>
        <input id="from" name="from" type="text" value="<?php echo $backdate;?>" class="form-control input-sm" style="width:120px">
 </div>
</div>
<div class="form-group" style="padding: 0 10px;">
    <span style="font-size:12px; display: block;">To</span>
    <div class="input-group">
            <span class="input-group-addon"><i class="fa fa-calendar"></i></span>
            <input id="to" name="to" type="text" value="<?php echo $frontdate;?>" class="form-control input-sm" style="width:120px">
     </div>
</div>
<div class="form-group" style="padding: 0 0; margin-top:15px;">
    <div class="input-group">
       <?php echo $this->Form->submit('OK',array('class'=>'btn btn-success','style'=>"height: 2em;")); ?> 
    </div>
</div>
</div>
<?php echo $this->Form->end() ?>

通过这种方式，当您提交表单数据时，会将您的网址写入您的网址 search?page=1&company=value&gig=value&etc...

并使用$this->request->query代替使用cakephp获取$_GET变量

public function search() {

        $this->viewBuilder()->template('allschedule');

        $scheduleto = date('Y-m-d', strtotime($this->request->query['to']." +1 days"));
        $schedulefrom =date('Y-m-d', strtotime($this->request->data['from']));

        if($this->request->query['company'] != 'all' && $this->request->query['gig'] == 'all')
        {
            $searchfilter = array(
                    'Schedule.shift_from > ' => $schedulefrom,
                    'Schedule.shift_from < ' => $scheduleto,
                    'Job.company' =>$this->request->query['company'],
                    'Schedule.status !=' =>0,
                    );
        }
        elseif($this->request->query['company'] == 'all' && $this->request->query['gig'] != 'all')
        {
            $searchfilter = array(
                    'Schedule.shift_from > ' => $schedulefrom,
                    'Schedule.shift_from < ' => $scheduleto,
                    'Schedule.gig_id' =>$this->request->query['gig'],
                    'Schedule.status !=' =>0,
                    );

        }
        elseif($this->request->query['company'] != 'all' && $this->request->query['gig'] != 'all')
        {
            $searchfilter = array(
                    'Job.company' =>$this->request->query['company'],
                    'Schedule.gig_id' =>$this->request->query['gig'],
                    'Schedule.shift_from > ' => $schedulefrom,
                    'Schedule.shift_from < ' => $scheduleto,
                    'Schedule.status !=' =>0,
                    );

         }
        else
        {
            $searchfilter = array(
                    'Schedule.shift_from > ' => $schedulefrom,
                    'Schedule.shift_from < ' => $scheduleto,
                    'Schedule.status !=' =>0,
                    );

        }


    $this->paginate = [
        'fields' => ['User.name', 'Schedule.shift_from', 'Schedule.id', 'Schedule.shift_to', 'Schedule.shift_description', 'Schedule.checkin', 'Schedule.checkout', 'Schedule.start', 'Schedule.stop', 'Schedule.comment', 'Schedule.attested'],
        'conditions' => $searchfilter,
        'contain' => ['Job','User'],
        'order' => [
            'shift_from' => 'ASC'
        ],
        'limit' => 30  //'limit' 
    ];
    $schedules = $this->paginate($this->Schedule);

        $this->set(compact('schedules'));
        $this->set('_serialize', ['schedules']);

}

希望这有帮助。
