控制器数据未传递给模型| Codeigniter

Question

我正在为我的页面创建一个活动/非活动状态按钮。但是来自控制器的数据不会发送到模型。

这是我的代码。

Controller Banner.php

public function banner_list()
 {

    $data['title'] = "Banner Type List";
    $session = $this->session->userdata('username');
    if(empty($session)){ 
        redirect('admin/');
    }

    $this->load->view("admin/banner/banner_list", $data);

    // Datatables Variables
    $draw = intval($this->input->get("draw"));
    $start = intval($this->input->get("start"));
    $length = intval($this->input->get("length"));


    $bannertype = $this->Banner_model->get_bannertypes();
    //echo json_encode($bannertype);
    $data = array();

    foreach($bannertype->result() as $r) {

$status = $r->status;
$btn = "";

if($status=="active") {

    $btn =   '<a href="<?php
    echo base_url();
?>admin/banner/update_status?sid=<?php
    echo $r->banner_id;
?>&svalue=inactive" class="btn btn-success">Active</a>' ;

} else {

    $btn =  ' <a href="<?php
    echo base_url();
?>admin/banner/update_status?sid=<?php
    echo $r->banner_id;
?>&svalue=active"
class="btn btn-danger">Inactive</a>' ;

}

    $data[] = array(

        $r->banner_url,
        $r->banner_name,
        $r->display_image,
        $btn,


            // '<button type="button" id="status_checks" class="status_checks btn-success" value="$r->status">"'.$r->status.'" </button>',
        '<span data-toggle="tooltip" data-placement="top" title="Edit"><button type="button" class="btn btn-info btn-circle btn-xs"  data-toggle="modal" data-target=".edit-modal-data"  data-banner_id="'. $r->banner_id . '"><span class="fas fa-pencil-alt"></span></button></span><span data-toggle="tooltip" data-placement="top" title="Delete"><button type="button" class="btn btn-danger btn-circle btn-xs delete" data-toggle="modal" data-target=".delete-modal" data-record-id="'. $r->banner_id . '"><span class="fa fa-times"></span></button></span>',

    );
  }

  $output = array(
       "draw" => $draw,
         "recordsTotal" => $bannertype->num_rows(),
         "recordsFiltered" => $bannertype->num_rows(),
         "data" => $data
    );
  echo json_encode($output);
  exit();
 }

Model Banner_model.php

function update_status(){
          $sid=$_REQUEST['banner_id'];
          $svalue=$_REQUEST['svalue'];

          if($svalue=='active'){
              $status='inactive';
          }else{
              $status='active';
          }
          $data= array(
                    'status' => $status
                      );
         $this->db->where('banner_id',$sid);
         return $this->db->update('banner_types',$data);                
         }

活动的非活动状态正确显示。但是状态没有更新，并且在控制台中没有错误。

我遵循此作为参考activate deactivate status using codeigniter

您不能直接从URL调用模型的函数“ update_status”。

要使其正常工作，您应该创建一个控制器函数并从那里调用该模型函数，不必担心$ _REQUEST仍将携带该函数供模型函数使用。

function update_status(){
   $this->Banner_model->update_status();
}
