在Codeigniter上传多个文件时出错 [英] Error when uploading multiple files in Codeigniter

问题描述

我试图在CodeIgniter中使用多个文件上传，但我收到一个错误：
您没有选择要上传的文件 p>

我的html代码：

 < input type =fileid =ModelImagename =ModelImage []multiple =multiplevalue =/> 
  

我的PHP代码：

  for（$ i = 0; $ i< count（$ _ FILES ['ModelImage'] [name]）; $ i ++）
 {
 if （$ _FILES ['ModelImage'] ['name'] [$ i]））
 {
 $ config ['upload_path'] ='./uploads/starmodel/'; 
 $ config ['allowed_types'] ='gif | jpg | png'; 
 $ config ['file_name'] =star _。$ lastid。_。$ i.strrchr（basename（$ _ FILES [ModelImage] [name] [$ i]），。 ）; 
 $ this-> upload-> initialize（$ config）; 
 
 if（$ this-> upload-> do_upload（'ModelImage'））
 {
 $ data = $ this-> upload-> data ; 
 $ udata = array（'ModelImage'=> $ config ['file_name']）; 
 $ this-> db-> where（'ModelID'，$ lastid）; 
 $ this-> db-> update（'starmodel'，$ udata）; 
} 
 else 
 {
 echo $ this-> upload-> display_errors（）; 
} 
} 
} 
  

解决方案>

name参数必须为 userfile

根据到CI文件上传文档：

默认情况下，文件来自一个名为userfile的窗体
，并且窗体必须是一个multipart类型：

 < form method =postaction =some_actionenctype =multipart / form-data/> 
< input type =filename =userfilesize =20/> 
< input type =submitvalue =upload/> 
< / form> 
  

据说，我不相信CI的库目前支持HTML5的文件上传。您应该围绕CI的论坛了解自定义库。

I am trying to use multiple file upload in CodeIgniter, but I'm getting an error: You did not select a file to upload.

My html code:

<input type="file" id="ModelImage" name="ModelImage[]" multiple="multiple"  value=""/>

My php code:

for($i = 0; $i < count($_FILES['ModelImage']["name"]); $i++)
{
  if (!empty($_FILES['ModelImage']['name'][$i]))
  {
    $config['upload_path'] = './uploads/starmodel/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['file_name']= "star_".$lastid."_".$i.strrchr(basename($_FILES["ModelImage"]["name"][$i]),".");
    $this->upload->initialize($config);

    if ($this->upload->do_upload('ModelImage'))
    {
      $data = $this->upload->data();
      $udata = array('ModelImage' => $config['file_name']);
      $this->db->where('ModelID', $lastid);
      $this->db->update('starmodel', $udata);
    }
    else
    {
      echo $this->upload->display_errors();
    }
  }
}

解决方案

The name parameter must be userfile

According to the CI File Uploading Documentation:

By default the upload routine expects the file to come from a form field called userfile, and the form must be a "multipart" type:

<form method="post" action="some_action" enctype="multipart/form-data" />
    <input type="file" name="userfile" size="20" />
    <input type="submit" value="upload" />
</form>

With that said, I do not believe CI's library currently supports HTML5's multiple file uploads. You should peak around CI's forums for custom libraries.
