Codeigniter 3 - 我可以從3張圖片中獲取圖片上傳的網址嗎？

Question

您好，我使用Codeigniter一次上傳3張圖片，我可以成功上傳，但我不知道如何從3張圖片中獲取網址（我只能從最後一張圖片獲取網址。）（我想插入3張圖片URL數據庫）

這裏是我的代碼

控制器

public function add_event() 
    { 

$config['upload_path']   = 'images/location'; 
    $config['allowed_types']  = 'gif|jpg|png'; 
    $config['max_size']    = 2048; 
    $config['max_width']   = 2000; 
    $config['max_height']   = 1500; 

$this->load->library('upload', $config); 

$this->upload->do_upload('userfile'); 
$this->upload->do_upload('userfile2'); 
$this->upload->do_upload('userfile3'); 

$data_upl = array('upload_data' => $this->upload->data()); 

$this->load->view('admin/success', $data_upl); 
} 

myuploadform視圖

 <?php echo form_open_multipart('admin/add_event') ?> 

      pic1 
      <input type="file" name="userfile" size="20" /> 

      pic2 
      <input type="file" name="userfile2" size="20" /> 


      pic3 
      <input type="file" name="userfile3" size="20" /> 

      <input type="submit" value="upload"/> 
     <?php echo form_close(); ?> 

我SUC cess頁面視圖（我想回顯3頁圖片的網址！但我只得到1個網址最後的圖像）（其實我想插入到數據庫）

<h1>Successfully Add</h1> 

<ul> 
<li><?php echo $upload_data['full_path'];?></li> 
</ul> 

Answer 1

我認爲這 - $> upload->數據（）取最後上傳文件的信息，是不是？你可以做的print_r（$ upload_data）？ 或者你可以嘗試這樣的事情嗎？

$upload_data=array(); 
$this->upload->do_upload('userfile'); 
$upload_data['1']= $this->upload->data()); 
$this->upload->do_upload('userfile2'); 
$upload_data['2']= $this->upload->data()); 
$this->upload->do_upload('userfile3'); 
$upload_data['3']= $this->upload->data()); 

Answer 2

$這個 - > upload->數據（）是最後上傳的數據，所以請儘量

........ 

$alldata=array(); 
$this->upload->do_upload('userfile'); 
$alldata[]=$this->upload->data(); 

$this->upload->do_upload('userfile2'); 
$alldata[]=$this->upload->data(); 

$this->upload->do_upload('userfile3'); 
$alldata[]=$this->upload->data(); 

$data_upl = array('upload_data' => $alldata); 

.......

<h1>Successfully Add</h1> 

<ul> 
<li><?php print_r($upload_data);?></li> 
</ul> 

Answer 3

在這個階段你正在上傳3個文件，但只獲取最後插入文件的數據。

$this->upload->do_upload('userfile'); 
$this->upload->do_upload('userfile2'); 
$this->upload->do_upload('userfile3'); 
$data_upl = array('upload_data' => $this->upload->data()); 

你應該得到每個文件的數據並推送到數組。像

$data = array(); 
$data['upload_data'] = array(); 
$this->upload->do_upload('userfile'); 
$data['upload_data'][0] = $this->upload->data(); 
$this->upload->do_upload('userfile2'); 
$data['upload_data'][1] = $this->upload->data(); 
$this->upload->do_upload('userfile3'); 
$data['upload_data'][2] = $this->upload->data();
