ThinkPHP file upload tutorial,

File uploading is a common function in many PHP program projects. Today, this article will share a complete example to implement the ThinkPHP file uploading function. The specific method is as follows:

1. Action part:

FileAction.class.php page code is as follows:

<&#63;php
class FileAction extends Action{
  function index(){
    $file=M('file');
    $list=$file->select();
    $this->assign('filelist',$list);
    $this->display();  
  }  
  function upload(){
    //文件上传地址提交给他,并且上传完成之后返回一个信息,让其写入数据库  
    if(empty($_FILES)){
      $this->error('必须选择上传文件');  
    }else{
      $a=$this->up();
      if(isset($a)){
        //写入数据库的自定义c方法
        if($this->c($a)){
          $this->success('上传成功');  
        }
        else{
          $this->error('写入数据库失败');  
        }
      }else{
        $this-error('上传文件异常,请与系统管理员联系');  
      }
    }
  }
  private function c($data){
    $file=M('file');
    $num  =  '0';
    for($i = 0; $i < count($data)-1; $i++) {
      $data['filename']=$data[$i]['savename'];      
      if( $file->data($data)->add())
      {
        $num++;
      }
    }
    if($num==count($data)-1)
    {
      return true;  
    }else
    {
      return false;
    }
  }
  private function up(){
    //完成与thinkphp相关的,文件上传类的调用  
    import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下
    $upload=new UploadFile();
    $upload->maxSize='1000000';//默认为-1,不限制上传大小
    $upload->savePath='./Public/Upload/';//保存路径建议与主文件平级目录或者平级目录的子目录来保存  
    $upload->saveRule=uniqid;//上传文件的文件名保存规则
    $upload->uploadReplace=true;//如果存在同名文件是否进行覆盖
    $upload->allowExts=array('jpg','jpeg','png','gif');//准许上传的文件类型
    $upload->allowTypes=array('image/png','image/jpg','image/jpeg','image/gif');//检测mime类型
    $upload->thumb=true;//是否开启图片文件缩略图
    $upload->thumbMaxWidth='300,500';
    $upload->thumbMaxHeight='200,400';
    $upload->thumbPrefix='s_,m_';//缩略图文件前缀
    $upload->thumbRemoveOrigin=1;//如果生成缩略图,是否删除原图
    
    if($upload->upload()){
      $info=$upload->getUploadFileInfo();
      return $info;
    }else{
      $this->error($upload->getErrorMsg());//专门用来获取上传的错误信息的  
    }  
  }
}
&#63;>

2. View template part:

The template file index.html code is as follows:

<html>
<body>
<volist name="filelist" id="vo">
 小图:<img src="__PUBLIC__/upload/s_{$vo['filename']}" /><br />
 大图:<img src="__PUBLIC__/upload/m_{$vo['filename']}" /><br />
</volist>
<form action="__URL__/upload" method="post" enctype="multipart/form-data">
  <input type="file" name="file[]" /><br />
  <input type="file" name="file[]" /><br />
  <input type="file" name="file[]" /><br />
  <input type="submit" value="上传" />
</form>

</body>
</html>
