多个图像上传导致500内部服务器错误 [英] Multiple image uploads cause 500 Internal Server Error
问题描述
我想在我的网站上实现多个部分，访问者可以上传他们的图像进行显示。
我让它在服务器上的测试文件夹中完美地工作，它回应文件是图像。[文件]成功上传，图像出现在服务器上。
I want to implement multiple sections on my website, where visitors can upload their images to be shown. I got it to work perfectly in a test folder on the server, where it echoes "File is an image. [file] succesfully uploaded" and the image appears on the server.
然而，随着这个脚本实际实现到网站（我将脚本复制到另一个文件夹），我得到了返回：500内部服务器错误。
However, with the actual implementation of this script into the website (I copied the scripts to a different folder), I get returned: 500 Internal Server error.
你们中有谁知道会导致这个问题的原因吗？
Does anyone of you know what could cause this issue?
HTML表格（在/entries.php中）：
The HTML form (in /entries.php):
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<link href="../../style.css" rel="stylesheet" type="text/css">
</head>
<body bgcolor="#000000">
<form action="upload.php" method="post" enctype="multipart/form-data"><p class="text">
Upload your entry here!:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit"></p>
</form>
</body>
</html>
PHP脚本（在upload.php中）：
The PHP script (in upload.php):
<?php
$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
推荐答案
upload_max_filesize 。
upload_max_filesize in the php.ini may need to be increased.
echo ini_get ("upload_max_filesize");
此命令将为您提供值，然后您可以进入php.ini并增加它不够。
This command will give you the value, then you can go into your php.ini and increase it if not sufficient.
在这种情况下，您可以在httpd.conf中创建一个类似于以下内容的新apache指令。
In this case you can create a new apache directive in your httpd.conf similar to the following.
FcgidMaxRequestLen bytes
FcgidMaxRequestLen bytes
<IfModule mod_fcgid.c>
MaxRequestLen 15728640
</IfModule>
由于每个托管公司的配置不同，因此流程可能会有所不同。但这是GoDaddy和Plesk的流程。
Since each hosting company has a different configuration the process may vary. But here is the process for GoDaddy and Plesk.
我可以在运行Parallels Plesk Panel的服务器上使用open_basedir吗？
Can I use open_basedir on my server running Parallels Plesk Panel?
您需要将其从PHP脚本所在的目录以及文件上载的目录中移出。如果这允许上传显然你知道.htaccess中有一个规则/指令导致问题。
You'll want to move it from the directory where your PHP script resides, and the directory where your files are uploading. If this allows uploads obviously you know there's a rule/directive in the .htaccess causing the issue.
