使用Codeigniter将php变量从视图传递到控制器以进行建模

Question

I want to pass php variable from view to controller then in my model using codeigniter.

The problem is that the variable is not getting passed to the controller.

Below is my View and Controller code.

Please note that the variable is got onload not through form inputs.

This is my View

 <script> $(document).ready(function (){ //fill data fillgrid(); function fillgrid(){ $("#loader").show(); $.ajax({ var subcategory_id = <?php echo $sub_id; ?>, url:'<?php echo base_url() ?>Shop/get_products_in_sub_subcategory/'+subcategory_id, type:'GET' }).done(function (data){ $("#fillgrid").html(data); $("#loader").hide(); }); } }); </script> 

Controller

 public function get_products_in_sub_subcategory(){ $subcategory_id = $this->uri->segment(3); $this->Account_model->get_products_in_sub_subcategory($subcategory_id); }

Hope this will help you :

Put your variable subcategory_id outside the ajax like this :

$(document).ready(function(e){
  fillgrid();
  function fillgrid()
  {
    var subcategory_id = '<?php echo $sub_id; ?>';
    $("#loader").show();
        $.ajax({
          url:'<?=base_url("Shop/get_products_in_sub_subcategory/");?>'+subcategory_id,
          type:'GET'
        }).done(function (data){
          alert(data);
          console.log(data)
            $("#fillgrid").html(data);
            $("#loader").hide();   
    });
  } 
});

And your method get_products_in_sub_subcategory should be like this :

public function get_products_in_sub_subcategory($subcategory_id)
{
    echo $subcategory_id;
    //$this->Account_model->get_products_in_sub_subcategory($subcategory_id);
    exit; 
}
