因此,我正在創建一個類的電子商務網站。在我的個人資料頁面上,我打算顯示存儲在數據庫中的各種信息。現在我只會搞亂用戶照片。我在模型中有一個函數,可以從DB'users'的'Image_Path'列中獲取用戶照片。我的問題是,每個配置文件視圖顯示相同的照片。我認爲它會返回所有圖片,也許只是將它設置爲第一個?從sql DB獲取單個用戶圖片(CodeIgniter)

這裏是模型

<?php 
class Profile_Model extends CI_Model 
{ 

    public function __construct() 
    { 
     $this->load->database(); 
    } 

// public function get_profile_picture() 
// { 
// 
//  $query = $this->db->get('users'); 
//  return $query -> result(); 
// } 
public function get_single_profile($id){ 
    //get whole table 

    $this->db->select('Username'); 
    $this->db->select('Image_Path'); 
    $this->db->from('users'); 
    $this->db->where('User_ID', $id); 
    $query = $this->db->get(); 
return $query->result(); 

}//end get_single_profile 

//for uploading profile pics 
public function set_profile_pic(){ 

} 

}//CLASS 
?> 

的控制器

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 

class Profile extends CI_Controller { 

public function __construct() 
{ 

    parent::__construct(); 
    $this->load->helper('form'); 
    $this->load->helper('url'); 
     $this->load->library('session'); //needed to use global session variables 
     $this->load->helper('language'); 
     $this->load->model('Profile/Profile_Model'); 
} 

public function index() 
{ 

    if($this->session->userdata('logged_in')) 
    { 

     $data['profilepicture'] = $this->Profile_Model->get_single_profile(); 

      $this->load->view('Profile/Profile', $data); 
    }// echo session variable logged_in 
    else{ 

     redirect(base_url().'Login'); //redirect to user profile view after verification) 
    } 
}//END Index 
public function logout(){ 
    $this->session->sess_destroy(); 
    redirect(base_url(). 'Login'); 
}//END LOGOUT 

public function display_profile_pic(){ 

    $data['profilepicture'] = $this->Profile_Model->get_profile_picture(); 
    $this->load->view('Product/Product', $data); 


} 
}//END CLASS 

<!DOCTYPE html> 
<html> 
<head> 
    <title><?php echo $_SESSION['logged_in']?></title> 
    <style type="text/css"> 
    .container {

首先,嘗試更改查詢的選定部分。它應該是這樣的:

$this->db->select('Image_Path, Username');

如果仍無法正常工作,嘗試呼應你的最後一次查詢中get_single_profile()

echo $this->db->last_query(); 
exit; 
+0

與退出標誌它什麼也沒有顯示,但我沒有看到最後一個查詢只是獲取數據庫中的第一個用戶圖片,當我嘗試將$ id變量傳遞給控制器​​時,它將作爲NULL出現。如果我通過特定的User_ID說27,它確實顯示該用戶行的圖片。 – user3412695

+0

我想這條線:$ this-> db-> where('User_ID',$ id); – user3412695

+0

會將用戶標識分配給$ id。 (我討厭這裏評論) – user3412695

0

改變了我的型號功能:

public function get_single_profile($id){ 
    //get whole table 


    $this->db->select('Image_Path'); 
    $this->db->from('users'); 
    $this->db->where('Username', $id); 
    $query = $this->db->get(); 
    echo $this->db->last_query(); 
    return $query->result(); 

}// end get_single_profile

And My Controller Inde x若要:

public function index() 
    { 

     if($this->session->userdata('logged_in')) 
     { 
      $data['profilepicture'] =  $this->Profile_Model->get_single_profile($this->session->userdata('logged_in') ); 

       $this->load->view('Profile/Profile', $data); 
     }// echo session variable logged_in 
     else{ 

      redirect(base_url().'Login'); //redirect to user profile  view after verification) 
     } 
    }//END Index 
模型

我從表中改變用戶名,並將其設置爲$的ID,我用了一個預先定義的會話變量$ ID設置爲會話控制器......我想
