php - 上传图片到服务器时打开流失败

Question

我正在将图像上传到我的服务器。我正在使用以下 php脚本:

<?php
include("mysqlconnect.php");

    function GetImageExtension($imagetype)
     {
       if(empty($imagetype)) return false;
       switch($imagetype)
       {
           case 'image/bmp': return '.bmp';
           case 'image/gif': return '.gif';
           case 'image/jpeg': return '.jpg';
           case 'image/png': return '.png';
           default: return false;
       }
     }
     
     
     
if (!empty($_FILES["uploadedimage"]["name"])) {

    $file_name=$_FILES["uploadedimage"]["name"];
    $temp_name=$_FILES["uploadedimage"]["tmp_name"];
    $imgtype=$_FILES["uploadedimage"]["type"];
    $ext = GetImageExtension($imgtype);
    $imagename=date("d-m-Y")."-".time().$ext;
    $target_path = "images/".$imagename;
    

if(move_uploaded_file($temp_name, $target_path)) {

    $query_upload="INSERT into 'images_tbl' ('images_path','submission_date') VALUES ('".$target_path."','".date("Y-m-d")."')";
    mysql_query($query_upload) or die("error in $query_upload == ----> ".mysql_error());  
    
}else{

   exit("Error While uploading image on the server");
} 

}

?>

我的代码有一些问题。我收到多个错误。

failed to open stream: No such file or directory in C:\xampp\htdocs\nipu\file upload\saveimage.php on line 29

Warning: move_uploaded_file(images/03-05-2016-1462289806.jpg): failed to open stream: No such file or directory in C:\xampp\htdocs\nipu\file upload\saveimage.php on line 29

Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpF912.tmp' to 'images/03-05-2016-1462289806.jpg' in C:\xampp\htdocs\nipu\file upload\saveimage.php on line 29

这里有什么问题？

Answer 1

1. 设置完整路径$target_path
2. 检查目标文件夹是否存在？
3. 同时为该文件夹设置“写入”权限。
