圖片路徑在Codeigniter中上傳並檢索它

我是codeigniter中的新成員。我試圖爲產品上傳圖片。現在我正在嘗試上傳每個產品只有一個圖像。圖片路徑在Codeigniter中上傳並檢索它

<?php defined('BASEPATH') OR exit('No direct script access allowed'); 
    class Users extends CI_Controller 
    { 
    function __construct() { 
    parent::__construct(); 
    $this->load->model('user'); 
    } 

    function add(){ 
     if($this->input->post('userSubmit')){ 

     //Check whether user upload picture 
     if(!empty($_FILES['picture']['name'])){ 
      $config['upload_path'] = 'uploads/images/'; 
      $config['allowed_types'] = 'jpg|jpeg|png|gif'; 
      $config['file_name'] = $_FILES['picture']['name']; 

      //Load upload library and initialize configuration 
      $this->load->library('upload',$config); 
      $this->upload->initialize($config); 

      if($this->upload->do_upload('picture')){ 
       $uploadData = $this->upload->data(); 
       $picture = $uploadData['file_name']; 
      }else{ 
       $picture = ''; 
      } 
     }else{ 
      $picture = ''; 
     } 

     //Prepare array of user data 
     $userData = array(
      'name' => $this->input->post('name'), 
      'email' => $this->input->post('email'), 
      'picture' => $picture 
     ); 

     //Pass user data to model 
     $insertUserData = $this->user->insert($userData); 

     //Storing insertion status message. 
     if($insertUserData){ 
      $this->session->set_flashdata('success_msg', 'User data have been added successfully.'); 
     }else{ 
      $this->session->set_flashdata('error_msg', 'Some problems occured, please try again.'); 
     } 
    } 
    //Form for adding user data 
    $data['data']=$this->user->getdata(); 
    $this->load->view('show',$data); 
} 

public function show() 
{ 
    #code 
    $data['data']=$this->user->getdata(); 
    $this->load->view('show',$data); 

}

}

我有這個在我的模型：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 
    class User extends CI_Model{ 
    function __construct() { 
    $this->load->database(); 
    $this->tableName = 'users'; 
    $this->primaryKey = 'id'; 
} 

    public function insert($data = array()){ 
    if(!array_key_exists("created",$data)){ 
     $data['created'] = date("Y-m-d H:i:s"); 
    } 
    if(!array_key_exists("modified",$data)){ 
     $data['modified'] = date("Y-m-d H:i:s"); 
    } 
    $insert = $this->db->insert($this->tableName,$data); 
    if($insert){ 
     return $this->db->insert_id(); 
    }else{ 
     return false; 
    } 
} 

    public function getdata() 
{ 
    $query=$this->db->get('users'); 
    return $query->result_array(); 
}

}

問題是我目前能夠沿着存儲數據，我有我的控制器做到了這一點在數據庫中帶有圖像名稱，並將選定的圖像上載到項目文件夾中的指定文件夾中，該文件夾當前爲：

root folder->image: 
       -application 
       -system 
       -uploads 
        .images(images are saved here)

現在問題是與視圖。我試圖動態訪問存儲的圖像是這樣的：

 <!DOCTYPE html> 
     <html> 
    <head> 
    <meta charset="utf-8"> 
    <title>show</title> 
    </head> 
     <body> 


    <table border='1' cellpadding='4'> 
     <tr> 
      <td><strong>User_Id</strong></td> 
      <td><strong>Name</strong></td> 
      <td><strong>Image</strong></td> 
      <td><strong>Option</strong></td> 
     </tr> 
    <?php foreach ($data as $p): ?> 
      <tr> 
       <td><?php echo $p['id']; ?></td> 
       <td><?php echo $p['name']; ?></td> 
       <td><img src="../uploads/images/<?php echo $p['picture']; ?>" /> </td> 
       <td> 
        <a href="#">View</a> | 

       </td> 
      </tr> 
    <?php endforeach; ?> 
    </table>

隨着圖像不來這個圖像源。只看到裂縫縮略圖。我也試過像這樣手動給圖像的根文件夾：

<img src="../uploads/images/image-0-02-03-15420e726f6e9c97408cbb86b222586f7efe3b002e588ae6bdcfc3bc1ea1561e-V.jpg" /> 
    or like this 
    <img src="../../uploadsimages/image-0-02-03-15420e726f6e9c97408cbb86b222586f7efe3b002e588ae6bdcfc3bc1ea1561e-V.jpg" />

但它沒有幫助。誰能幫我？任何建議和建議都非常歡迎。謝謝。

試試這個

 <img src="<?php echo base_url('uploads/images/'.$p['picture']); ?>"/> 

insted of this line 
<img src="../uploads/images/<?php echo $p['picture']; ?>" />

還設置你的文件夾位置corectly

是的，它也是這樣工作的。 –

只是一個愚蠢的錯誤。我讓我的虛擬主機指向根文件夾的index.html。所以只需指向根文件夾，問題就解決了。
