Codeigniter：如何在Codeigniter的单个控制器函数中调用多个模型函数

Question

I am new to coidigniter.

If I am calling single model method from controller function then its working fine.

If I amt try to call more than one model function from single model, through single controller function, then I get

Fetal Error:Call to a member function result() on Boolean

my code look like this

controller.php

public function get_details(){

   $this->my_model->get_company();  //first call

   $this->my_model->get_employee();  //second call

}

my_model.php

public function get_company(){

 $qry="CALL get_company_details";

 $result=$this->db->query($qry);

 foreach($result->result() as $row){

   $data[]=$row;

 }

return $data;

}


public function get_employee(){

 $qry="CALL get_employee_details";

 $result=$this->db->query($qry);

 foreach($result->result() as $row){

   $data[]=$row;

 }

return $data; 

} 

Can I call like that. Please help me...

Answer 1

Simple typo:

Change

function get_company(){

to

function get_employee(){

You have defined same function twice.

Answer 2

Make sure your database connection is ok in application/config/database.php

$data = array();

    $qry="SELECT * FROM . . . . ."; // your query 

    $result=$this->db->query($qry);
    if($result->num_rows() > 0){
     foreach($result->result() as $row){

       $data[]=$row;

     }
    }


    return $data; 

Answer 3

Replace

$result=$this->db->query($qry);
 foreach($result->result() as $row){
   $data[]=$row;
 }
return $data;

to

return $result->result_array();

That should solve your problem. You can check result_array() section of CodeIgniter documentation.
