无法将 url 数据获取到模型类中

Question

目前我有一个表格，显示产品所有状态的计数。现在这些计数是可点击的，并导致另一个页面显示被点击的任何项目的详细数据。我可以通过将其放入 URL 中来获取此数据

<a target='_blank' href='".site_url('reports/lists?source=' . $title . '&status=' . $status) . "'>

这会正确地将我在 URL 中单击的产品的数据。 现在我正在尝试从 URL 中获取这些数据，并根据 URL 中存在的值相应地过滤数据，但是即使在我使用了 $leadsource = $this->input->get('status');

查看类：

<?php  
$sess=$this->session->userdata(); 
$post = array('fstatus'=> $sess['fstatus'],'fsource'=> $sess['fsource']);
$postd = json_encode(array_filter($post));
$leadstatus = $this->input->get('source');
?>
<table id="item-list">
            <tr> 
                <th>Ref.No#</th>
                <th>Source</th>
            </tr>
</table>

<script>
$(document).ready(function() {
  function sendreq(){
    setpostdatas();cleartable();getleads();
  }

   var userrole = "<?php echo $this->session->userdata('clientrole')?>";
   var leadsource = "<?php echo $leadsource ?>";
   var slug = '<?php echo $slug?>';
   var postd = '<?php echo $postd; ?>';
if( userrole > 1 && userrole != 5){
    $('#item-list').DataTable({
        "processing": true,
        "stateSave": true,
        "serverSide": true,
        "ordering": false,
          "createdRow": function( row, data, dataIndex){
            $(row).has( "div.overdueupdate" ).css('background-color','#FFC7CE');
              },
        "ajax": {
            url: "<?php echo site_url(); ?>reports/loadLeads",
            data: {slug: slug, postdata: postd, leadsource: leadsource},
            type : 'POST',
            "dataSrc": function ( d ) {
                d.myKey = "myValue";
                if(d.recordsTotal == 0 || d.data == null){
                   $("#item-list_info").text("No records found");
                    $("#item-list_processing").css("display","none");
                }
                return d.data;
            }
        },
        'columns': [
            {"data": "id", "id": "id"},
            {"data": "refno", "refno": "refno"},
            {"data": "source", "source": "source"},   
        ]
    });
  }

控制器类：

public function loadLeads($p=''){
        $leadsource = $this->input->get('status');
        if(isset($_POST['postdata'])){
            if($_POST['postdata'] != null && $_POST['postdata'] != 'null'){
                $post=$_POST['postdata'];
            }
            $post = json_decode($post,true);
            unset($post['slug']);
            unset($post['page']);
            $sort = $post['afsort'];
            if($sort == "asc"){
                $sortQ = 'l.updated_date asc,';
            }else if ($sort == "desc"){
                $sortQ = 'l.updated_date desc,';
            }
        }
        $offset = (int)$_POST['start'] ;
        $pstdatas = explode(',', $_POST['postdata']);
        unset($pstdatas['item-list_length']);
        if($this->session->userdata('clientrole') == 1 || $this->session->userdata('clientrole') == 5 ){
            $content['leads']=$this->leads_model->get_pagination($_POST['length'],$offset,$where,'',false,$sortQ?$sortQ:'l.assign_status =\'Unassigned\' desc,',$all,$leadsource);          
        }else{
            $content['leads']=$this->leads_model->get_pagination($_POST['length'],$offset,$where,'',false,$sortQ?$sortQ:'l.assigned_date desc,',$all,$leadsource);
        }

public function lists($slug='')
    {
        $this->load->model(array('crm/crm_model'));  
        $content['propertyrefnos']=$this->crm_model->property_refnos();
        $content['is_mobile'] = $this->ismob;
        $content['sources']= $this->sources_model->get_active(array(),'id,title','title asc' );
      }

模型类：

function get_pagination($num, $offset, $cond='',$order='',$unlimit=false,$add_order='',$all='',$leadsource)
    {
        $this->db->select("l.*");
        $sess=$this->session->userdata(); 
        if(is_array($cond) && count($cond)>0){ $this->db->where($cond); }

        if(empty($cond)){           
            if($sess['afstatus']==''){
                $leadsource = $this->input->get('status');
                if($searchdata['keyword'] !='' || $searchdata['fstatus'] !='' || $searchdata['fproject'] || $searchdata['fdevelop'] || $all != ''){
                $this->db->where_in('lead_status',array(1,8,9,2,3,4,10,11)); 
                $this->db->where('lead_source',$leadsource);
                }
                else            {
                $this->db->where_in('lead_status',array(1,8,9,11));
                $this->db->where('lead_source',$leadsource);}
                }
        }
....
$query =  $this->db->get();
return $query->result_array();

如您所见，我已尝试在我的控制器类和模型中添加$leadsource = $this->input->get('status');，但它们都没有返回我想要的 url 数据。但是将此代码放在我的列表函数控制器下会返回来自 URL 的数据，但我希望它发生在我的 loadLeads 函数中。

我在 loadleads 控制器中添加了以下内容，并且 source 的输出始终为空：

        $output = array(
            "source" => $leadsource,
            "data" => $data 
        );

        echo json_encode($output); 
        exit();

您必须在控制器中捕获参数，而不是在模态中。

$leadsource = $this->input->get('status');

因为这个参数是通过 URL 传递的，所以你必须使用$_GET 来访问它们。

public function loadLeads($p=''){
     $leadsource = $this->input->get('status');

     // your other controller codes here
}
