Fine-uploader上传错误

所以我想在我的网站上使用fine-uploader（最小的jQuery演示）上传一些图片到web服务器上传文件夹。然而，上传总是失败，我不知道为什么。Fine-uploader上传错误

当我点击“上传文件”，然后选择一个文件时，它开始上传（进度开始填充），当它到达100％它说“上传失败”，并给出了检查元素此错误： "Upload failed" error (Bigger size image)

这里是upload.html：

<!DOCTYPE html> 
<html> 
    <head> 
    <meta charset="utf-8"> 
    <title>Fine Uploader - jQuery Wrapper Minimal Demo</title> 
    <link href="css/fineuploader-3.6.3.css" rel="stylesheet"> 
    </head> 
    <body> 
    <div id="fine-uploader"></div> 

    <script src="http://code.jquery.com/jquery-latest.js"></script> 
    <script src="js/jquery.fineuploader-3.6.3.js"></script> 
    <script> 
     function createUploader() { 
     var uploader = new qq.FineUploader({ 
      element: document.getElementById('fine-uploader'), 
      request: { 
      endpoint: 'upload_file.php' 
      } 
     }); 
     } 

     window.onload = createUploader; 
    </script> 
    </body> 
</html>

而且upload_file.php：

<?php 
for($i=0; $i<count($_FILES['file']['type']); $i++) { 
$allowedExts = array("gif", "jpeg", "jpg", "png"); 
$temp = explode(".", $_FILES["file"]["name"][$i]); 
$extension = end($temp); 
if ((($_FILES["file"]["type"][$i] == "image/gif") 
|| ($_FILES["file"]["type"][$i] == "image/jpeg") 
|| ($_FILES["file"]["type"][$i] == "image/jpg") 
|| ($_FILES["file"]["type"][$i] == "image/pjpeg") 
|| ($_FILES["file"]["type"][$i] == "image/x-png") 
|| ($_FILES["file"]["type"][$i] == "image/png")) 
&& ($_FILES["file"]["size"][$i] < 50000000) 
&& in_array($extension, $allowedExts)) 
    { 
    if ($_FILES["file"]["error"][$i] > 0) 
    { 
    echo "Return Code: " . $_FILES["file"]["error"][$i] . "<br>"; 
    } 
    else 
    { 
    echo "Upload: " . $_FILES["file"]["name"][$i] . "<br>"; 
    echo "Type: " . $_FILES["file"]["type"][$i] . "<br>"; 
    echo "Size: " . ($_FILES["file"]["size"][$i]/1024) . " kB<br>"; 
    echo "Temp file: " . $_FILES["file"]["tmp_name"][$i] . "<br>"; 

    if (file_exists("upload\\" . $_FILES["file"]["name"][$i])) 
     { 
     echo $_FILES["file"]["name"][$i] . " already exists. "; 
     } 
    else 
     { 
     move_uploaded_file($_FILES["file"]["tmp_name"][$i], 
     "\\upload\\" . $_FILES["file"]["name"][$i]); 
     echo "Stored in: " . "upload\\" . $_FILES["file"]["name"][$i]; 
     } 
    } 
    } 
else 
    { 
    echo "Invalid file"; 
    } 
} 

?>

可能是一个好主意，检查你的上传目录存在，目录中的脚本匹配和权限在该目录设置。 – 2013-07-23 13:15:23

该目录存在但我如何检查权限？并且需要哪些权限才能够上传到该目录？ – DaftDev

如果你的服务器是windows，你不需要设置任何权限。如果你在Linux上，你可以。您应该可以使用您的FTP客户端更改权限。这里是关于[文件权限]（http://www.elated.com/articles/understanding-permissions/）的文章。权限应该是755. – 2013-07-23 13:34:19

您没有返回有效的JSON响应。一个简单的方法可以使用json_encode。

将当前的回显行放入数组中，并在使用json_encode后回显该数组，以获得有效的JSON响应。

第一件事是从循环中删除它。即使它支持多上传，它只能发送1个文件。看到火虫。然后我使用文件夹的绝对路径，然后将响应转换为JSON格式。上面提供的代码有意见。
