I am currently having a bit of a nightmare with a webserver I have. I have trawled just about every Stack Overflow page I can find and still no success.
I have a webserver running locally which I would test these settings on first, and everything works but whenever I apply the same settings to my main server, no such luck.
I have gone right back to basics just by using a simple html page and php page to process the request and this still fails with anything over 1MB.
For reference, this is my html script:
<!DOCTYPE html>
<html>
<body>
<form action="test.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
This is my test.php page to process the request:
<?php
$target_dir = "";
$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"] > 8000000) { //8mb
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.";
}
}
?>
This is just the basic php image upload script from w3 Schools - that is what this problem has reduced me to!
What I have tried:
- Editing the php.ini file then restarting apache
- Changing the html form so that it includes enctype="multipart/form-data" within the form header
- Adding .htaccess to the root www/html folder where the files are
- changing the bit of the upload script which specifies the maximum allowed image size:
The error I am getting is:
Warning: getimagesize(): Filename cannot be empty in /var/www/html/test.php on line 8
File is not an image.Sorry, your file was not uploaded.
Can anyone help me out? I have also tried to look into disabling mod_security but I couldn't even find that on my apache2 server.
Many thanks.
