Question

ma'am /先生我有一个问题，我想在我的桌子内查看“未找到搜索”，但是当点击搜索按钮时，它将转到空白页面找不到该搜索：

这是我的模特：

function search($keyword)
{
    $this->db->like('Firstname',$keyword);
    $this->db->or_like('Middlename',$keyword);
    $this->db->or_like('Lastname',$keyword);
    $this->db->or_like('Idnumber',$keyword);
    $query  =   $this->db->get('studentinformation');
    if ( $query->num_rows() > 0 )
            return $query->result();
    else
    return FALSE;
}

这是我的控制者：

function search_keyword()
{
    $session_data = $this->session->userdata('logged_in');
    $data['Username'] = $session_data['Username'];
    $keyword    =   $this->input->post('keyword');
    $data['results']    =   $this->model_adminlogin->search($keyword);
    if ( !empty($data) ) 
         echo  'Search not found';
    else
                $this->load->view('result_view',$data);
}

这是我的观点：

<div class="z table-responsive">
    <table class=" table table-hover">         
        <thead >
            <tr>
                <th>ID Number</th>
                <th>First name</th>
                <th>Middle name</th>
                <th>Last name</th>
                <th>Sex</th>     
            </tr>
        </thead><?php   
            if ( !empty($data) ) 
            echo  'Search not found';
            else
            {
                <tbody>
                    foreach($results as $row)
                    { ?>
                            <tr>                             
                                <td><?php echo $row-> Idnumber ?></td>
                                <td class="text-capitalize "><?php echo $row -> Firstname ?></td>
                                <td class="text-capitalize"><?php echo $row->Middlename ?></td>
                                <td class="text-capitalize"><?php echo $row-> Lastname ?></td>
                                <td class="text-capitalize"><?php echo $row-> Sex?></td>
                                <td>
                                    <a href="<?php echo site_url('viewstudentinalpha/viewspecific/'.$row->Id) ?>" class="btn btn-info " style="font-size: 18px;" type="submit" name="submit" role="button">Option</a>
                                 </td>
                            </tr>
                        <?php
                    }           
      } ?>
        </tbody>
  </table>
</div>

尝试在视图文件中更改以下代码：

<div class="z table-responsive" >
            <table class=" table table-hover"  >


                 <thead >
                             <tr >

                                   <th>ID Number</th>
                                   <th>First name</th>
                                   <th>Middle name</th>
                                   <th>Last name</th>
                                   <th>Sex</th>

                           </tr>
                      </thead>

    <?php



           if ( !isset($results) ) 
{
         echo  'Search not found';

       }  else{   foreach($results as $row){

                            ?>




    <tbody>
          <tr>


                  <td><?php echo $row-> Idnumber ?></td>
                  <td class="text-capitalize "><?php echo $row -> Firstname ?></td>
                   <td class="text-capitalize"><?php echo $row->Middlename ?></td>
                   <td class="text-capitalize"><?php echo $row-> Lastname ?></td>
                   <td class="text-capitalize"><?php echo $row-> Sex?></td>
                            <td>
                                <a href="<?php echo site_url('viewstudentinalpha/viewspecific/'.$row->Id) ?>" class="btn btn-info " style="font-size: 18px;" type="submit" name="submit" role="button">Option</a>

                             </td>
         </tr>
      </tbody>




              <?php
              }


       }

                         ?>




            </tbody>
            </table>
         </div>

尝试此编码

控制器

  function search_keyword()
        {
      $session_data = $this->session->userdata('logged_in');

                $data['Username'] = $session_data['Username'];

               $keyword    =   $this->input->post('keyword');

           $data['results']    =   $this->model_adminlogin->search($keyword);
         if ( empty($data['results']) ) 
    {
             $data['message'] = 'Search not found';

    }
 $this->load->view('result_view',$data);
    }

查看编码

<div class="z table-responsive" >
            <table class=" table table-hover"  >


                 <thead >
                             <tr >

                                   <th>ID Number</th>
                                   <th>First name</th>
                                   <th>Middle name</th>
                                   <th>Last name</th>
                                   <th>Sex</th>

                           </tr>
                      </thead>
                    <tbody>

    <?php if ( isset($message) ):
         echo  "<tr>".$message."</tr>";

    else:   foreach($results as $row):?>





          <tr>


                  <td><?php echo $row-> Idnumber ?></td>
                  <td class="text-capitalize "><?php echo $row -> Firstname ?></td>
                   <td class="text-capitalize"><?php echo $row->Middlename ?></td>
                   <td class="text-capitalize"><?php echo $row-> Lastname ?></td>
                   <td class="text-capitalize"><?php echo $row-> Sex?></td>
                            <td>
                                <a href="<?php echo site_url('viewstudentinalpha/viewspecific/'.$row->Id) ?>" class="btn btn-info " style="font-size: 18px;" type="submit" name="submit" role="button">Option</a>

                             </td>
         </tr>
      </tbody>




              <?php endforeach; endif; ?>





            </tbody>
            </table>
         </div>

Answer 3

试试这段代码

<强>控制器

 function search_keyword()
 {
    $session_data = $this->session->userdata('logged_in');

    $data['Username'] = $session_data['Username'];

    $keyword    =   $this->input->post('keyword');

    $data['results']    =   $this->model_adminlogin->search($keyword);
    if ($data['result'] == FALSE ) 
    {
      $data['message'] = 'Search not found';

      $this->load->view('result_view',$data);

    }else{
      $this->load->view('result_view',$data);
 } 
}

查看

<div class="z table-responsive" > <table class=" table table-hover" > <thead > <tr > <th>ID Number</th> <th>First name</th> <th>Middle name</th> <th>Last name</th> <th>Sex</th> </tr> </thead> <tbody> <?php if(isset($result)){ foreach($results as $row){ ?> <tr> <td><?php echo $row-> Idnumber ?></td> <td class="text-capitalize "><?php echo $row -> Firstname ?></td> <td class="text-capitalize"><?php echo $row->Middlename ?></td> <td class="text-capitalize"><?php echo $row-> Lastname ?></td> <td class="text-capitalize"><?php echo $row-> Sex?></td> <td> <a href="<?php echo site_url('viewstudentinalpha/viewspecific/'.$row->Id) ?>" class="btn btn-info " style="font-size: 18px;" type="submit" name="submit" role="button">Option</a> </td> </tr> <?php } } if(isset($meassge)) { echo $message; } ?> </tbody> </table>
