CodeIgniter - 从模型到控制器向页面发送数组[关闭]

Question

I am trying to pass the array to the view page and put the items in a listbox/dropdown. Where am I going wrong in this code?

Model

public function get_suppliers(){
        $type = "SUPPLIER";
        $this->db->where('usertype', $type);
        $query = $this->db->get('users');
        foreach ($query->result() as $row){
            $results = array(
                'userid' => $row->userid,
                'firstname' => $row->firstname,
                'lastname' => $row->lastname,
                'company' => $row->company
            );

        }
        return $results;
    }

Controller

$this->load->model('user_model');
$data['supplier']= $this->user_model->get_suppliers();
$this->load->view('include/header.php');
$this->load->view('addvehicle_view', $data);
$this->load->view('include/footer.php');

View

<?php
  if(isset($supplier)){
      foreach ($supplier as $info){
      echo'<option value="' . $info->userid . '">' . $info->company . ' - ' . $info->lastname . ', ' . $info->firstname . '</option>';
    }
  }
  ?>

Answer 1

In get_suppliers():

$results = array(); // just in case there is no record

foreach (...) {
    $results[] = array( // you forgot the "[]"
        ...
    );
}

Another issue: your model (once fixed) returns an array of arrays, whereas your view expects an array of objects.

Straight to the point, here's your new sexy model method:

public function get_suppliers() {
    return $this->db
        ->where('usertype', 'SUPPLIER')
        ->get('users')
        ->result();
}
