添加失败，是图片上传的问题 希望各位大大能帮帮小弟解决，

解决方案 »

  1.   

    给你一个代码你看一下，<?php 
    header("Content-type:text/html;Charset=utf-8");
    $uploaddir = dirname(__FILE__)."\\upload\\"; //dirname获得当前文件的路径
    $uploadname =time().basename($_FILES['upfile']['name']);
    $uploadfile = $uploaddir.$uploadname;
    $type= $_FILES['upfile']['type'];
    //echo preg_match("/\\.(jpg|gif|png)$/i",$uploadfile);
    if($_FILES["upfile"]["error"]>0){
    echo "error files";
    }else
    if (getimagesize($_FILES['upfile']['tmp_name'])){ 
    //if(strcmp($type,"image/bmp") == 0){
        if($_FILES["upfile"]["size"]<1000000){
      if(is_uploaded_file($_FILES['upfile']['tmp_name'])){
       if(move_uploaded_file($_FILES['upfile']['tmp_name'],$uploadfile)){
                         echo "<script language='javascript'>document.URL='manager/message.php?id=$uploadname';</script>";
      }
    else{
      echo "上传失败";
      }
          }
        }
        else{
         echo "<script language='javascript'>document.URL='manager/message.php?id=0';</script>";
        }
    }
    else{
    echo "<script language='javascript'>document.URL='manager/message.php?id=1';</script>";
    }
    ?> 
      

  2.   

    把这句is_uploaded_file($_FILES["yw_pic"][tmp_name]
    改成is_uploaded_file($_FILES['yw_pic']['tmp_name']
    试
      

  3.   


    上面注释不是很清楚吗？
    $destination_folder="uploadimg/"; //上传文件路径
     if (!is_uploaded_file($_FILES["yw_pic"][tmp_name]))
    改成 if (!is_uploaded_file($_FILES[yw_pic][tmp_name]))上传后的图片 在 $destination = $destination_folder.time().".".$ftype;
    也 就是uploadimg/当前时间.图片文件后缀名 
    这样写有缺陷 当相同时间上传就会有重名文件 改成
    $str=time().rand(4,4);
    $destination = $destination_folder.md5($str).".".$ftype;
    哥们，真怕丢了工作好好看看PHP函数手册
