在PHP中檢索兩個表中的數據Codeigniter

Question

我想檢索一個表中的數據和另一個表中的一些數據的數量，我也想知道如何在單個foreach循環中顯示這些數據。

型號

public function counter(){ 
    $this->db->where('package_id', $id); 
    $this->db->from('gt_package'); 
    $cnt = $this->db->count_all_results(); 
} 

控制器

public function package_category_listing() 
{ 
    $data['records'] = $this->gt_package_model->counter(); 
    $query = $this->db->get("gt_package_category"); 
    $data['records'] = $query->result(); 
    $this->load->view('admin/package/package_category_listing',$data); 
} 

查看部分：

<?php foreach ($records as $r) { ?>  
     <div class="col-sm-6 col-md-3 col-xs-12"> 
      <div class="bg-purple"> 
       <h4 class="text-white"> 
        <?php echo $r->category_name; ?> 
       </h4> 
       <span>200</span>&nbsp;&nbsp;Packages 
       <br> 
       <a style="margin-top: 10px;" href="<?php echo site_url() . "/gt_package/listing/" . $r->category_id ?>" class="btn btn-default">View Packages</a> 
      </div> 
     </div> 
    <?php } ?>

按照您的問題來傳遞數據模型到控制器代碼波紋管

型號：

public function counter() 
{ 
     $this->db->where('package_id', $id); 
     $this->db->from('gt_package'); 
     $query = $this->db->get('gt_package'); 
     $cnt = $query->num_rows(); 
     return $cnt; 
} 

控制器：

public function package_category_listing() 
{ 
    $data['records'] = $this->gt_package_model->counter(); 
    $query = $this->db->get("gt_package_category"); 
    $data['records'] = $query->result(); 
    $this->load->view('admin/package/package_category_listing',$data); 
    if($res){ 
     $data['result'] = $res; 
     $this->load->view('manage_accounts_view', $data); 

    } else { 

     echo "Fail"; 

    } 
    print_r($data['result']); 
}
