I have a PHP script that uploads files. However, when the total upload size is too great, the script exits on about 97% uploaded, and drops me back to the previous page. I can't get it to throw an error message, so I'm not sure what's causing it. No files actually get uploaded or added to the database.
I thought it could be a memory issue, so at the top of my upload script, I have:
ini_set("memory_limit", "64M");
The odd thing is, no matter how many files I try and upload, if it wants to exit, it always exits right at the final stage of uploading (~97%). I assume if it was a memory issue, it would exit as soon as it ran out.
Another thought was exceeding the maximum allowed files, but checking the configuration, I see
ini_get("max_file_uploads") = 20
My entire PHP script is as follows (ignore the odd variable casing, I'm keeping this script in the same format as an older one created by someone else).
ini_set("memory_limit", "64M");
if (!isset($_POST['SiteID']) || !filter_var($_POST['SiteID'], FILTER_VALIDATE_INT)) {
header("Location: ./");
exit();
}
$SiteID = $_POST['SiteID'];
if (!isset($_POST['GalleryID']) || !filter_var($_POST['GalleryID'], FILTER_VALIDATE_INT)) {
header("Location: ./?SiteID=" . $SiteID . "&error=upload");
exit();
}
$GalleryID = $_POST['GalleryID'];
$ImageFile = $_FILES['ImageFile'];
$Extensions = array("jpg", "jpeg");
$Timestamp = date("U");
require_once("db.php");
for ($X = 0; $X < count($_FILES['ImageFile']['name']); $X++) {
$Extension = strtolower(pathinfo($ImageFile['name'][$X], PATHINFO_EXTENSION));
if (in_array($Extension, $Extensions)) {
if ($ImageFile['error'][$X] === UPLOAD_ERR_OK) {
if ($ImageFile['size'][$X] <= 5 * 1024 * 1024) {
$Filename = $GalleryID . "-" . $Timestamp . "-" . $X . "." . $Extension;
move_uploaded_file($ImageFile['tmp_name'][$X], "uploads/" . $Filename);
mysql_query("INSERT INTO NewGalleryImages SET GalleryID = $GalleryID, ImageFile = '$Filename', ImageCaption = ''");
$Dimensions = getimagesize("uploads/" . $Filename);
$Width = ($Dimensions[0] > 768 ? 768 : $Dimensions[0]);
$Height = ($Dimensions[1] / $Dimensions[0]) * $Width;
$Expl = explode(".", $Filename);
$LargeFilename = $Expl[0] . "_gallery." . $Expl[1];
$Source = "uploads/" . $Filename;
$Canvas = imagecreatetruecolor($Width, $Height);
$LargeImage = imagecreatefromjpeg($Source);
imagecopyresampled($Canvas, $LargeImage, 0, 0, 0, 0, $Width, $Height, $Dimensions[0], $Dimensions[1]);
imagejpeg($Canvas, "uploads/" . $LargeFilename, 100);
$Width = 200;
$Height = ($Dimensions[1] / $Dimensions[0]) * $Width;
$Expl = explode(".", $Filename);
$ThumbFilename = $Expl[0] . "_thumb." . $Expl[1];
$Source = "uploads/" . $Filename;
$Canvas = imagecreatetruecolor($Width, $Height);
$ThumbImage = imagecreatefromjpeg($Source);
imagecopyresampled($Canvas, $ThumbImage, 0, 0, 0, 0, $Width, $Height, $Dimensions[0], $Dimensions[1]);
imagejpeg($Canvas, "uploads/" . $ThumbFilename, 100);
} else {
mysql_close();
header("Location: ./?SiteID=" . $SiteID . "&error=size");
exit();
}
} else {
mysql_close();
header("Location: ./?SiteID=" . $SiteID . "&error=unknown");
exit();
}
} else {
mysql_close();
header("Location: ./?SiteID=" . $SiteID . "&error=type");
exit();
}
}
mysql_close();
header("Location: ./?SiteID=" . $SiteID . "&uploaded");
exit();
// var_dump($_POST);
// var_dump($_FILES);
// var_dump($ImageFile);
The upload fails when I upload 13 files at a total of 14.2MB, but succeeds when I upload 8 files at a total of 4.82MB.
The initial form that leads to this script it:
<form action="gallery-upload.php" method="post" enctype="multipart/form-data">
<input class="form-control" name="ImageFile[]" type="file" multiple required>
<input type="hidden" name="SiteID" value="<?=$SiteID?>">
<input type="hidden" name="GalleryID" value="<?=$GalleryID?>">
<button class="btn btn-primary" type="submit">Upload Images</button>
</form>
Any ideas how to fix this? Or at least view an error as to why the script it exiting?
