Question

我想计算行数并在我的视图中显示链接..当用户点击链接将转到特定网址的数字时..

这是我的模特：

 function getrequirementsdate($date1,$date2)
 {

    $this->db->select('*');
    $this->db->from('requirements');
    $this->db->join('role','role.role_id=requirements.role_id');
    $this->db->where('created_date >=', $date1);
    $this->db->where('created_date <=', $date2);
    $query = $this->db->get();
    //echo $this->db->last_query();
    $rowcount = $query->num_rows();
    //echo $rowcount;
    return $query->result();
}

另一种模式：

function getrequirements()
{
    $this->db->select('*');
    $this->db->from('requirements');
    $this->db->join('role','role.role_id=requirements.role_id');
    $query = $this->db->get();
     // echo $this->db->last_query();
    return $query->result();
}

这是我的控制器：

public function view_requirements_bydate($date1="",$date2="")
{
    $data["msg"]="";
    $data = array(
        'total_item' => $this->ReportModel->getrequirementsdate($date1,$date2)
                  );
    if($date1=='' && $date2=='' )
    {
      $data['view_requirements'] = $this->ReportModel->getrequirements();
    }
    else
    {
      $data['view_requirements'] = $this->ReportModel->getrequirementsdate($date1,$date2);
    }
    $this->load->view('Reports/view_requirements_bydate',$data);
}

查看:(此处显示计数编号）..

<body>
<h4>No of Requirements:</h4>
</body>

这是我的表格代码：

<div class="box-body">
          <table id="" class="table table-bordered table-hover">
            <thead>
              <tr>
               <th>Role Name</th>
              <th>Vacancies</th>
              <th>Experience</th>
              <th>Job Description</th>
              <th>Hiring Contact Number</th>
              <th>Hiring Contact Name</th>
              <th>Date</th>

            </tr>
            </thead>

             <?php 
               foreach ($view_requirements as $idata) 
                {
                ?>


            <tbody>

                  <tr id="domain<?php echo $idata->req_id;?>">
                    <td><?php echo $idata->role_name;?></td>
                    <td><?php echo $idata->vacancies;?></td>

                    <td><?php echo $idata->experience;?></td>
                    <td><?php echo $idata->jd;?></td>
                    <td><?php echo $idata->hiring_contact_number;?></td>
                    <td><?php echo $idata->hiring_contact_name;?></td>
                     <td><?php echo $idata->created_date;?></td>



                    </tr>



            <?php
          }
            ?>


            </tbody>

          </table>

任何人都可以帮我解决这个问题谢谢..

模型1

function getrequirementsdate($date1,$date2)
{

    $this->db->select('*');
    $this->db->from('requirements');
    $this->db->join('role','role.role_id=requirements.role_id');
    $this->db->where('created_date >=', $date1);
    $this->db->where('created_date <=', $date2);
    $query = $this->db->get();
    return $query->result_array();
}

模型2

function getrequirements()
{
    $this->db->select('*');
    $this->db->from('requirements');
    $this->db->join('role','role.role_id=requirements.role_id');
    $query = $this->db->get();
    return $query->result_array();
}

<强>控制器

function view_requirements_bydate($date1="",$date2="")
{
    $data["msg"]="";

    if($date1 =='' && $date2 =='' )
    {
        $data['view_requirements'] = $this->ReportModel->getrequirements();
    }
    else
    {
        $result_array = $this->ReportModel->getrequirementsdate($date1,$date2);

        $data['total_item'] = count($result_array);
        $data['view_requirements'] = $this->ReportModel->getrequirementsdate($date1,$date2);

    }
    $this->load->view('Reports/view_requirements_bydate',$data);
}
