- check whether the files uploaded are jpg's
- rename all uploaded jpg's using this naming convention "$filename = uniqid("")."_1".".".$extention;" resulting in a filename like 44d0d32a83aaa_1.jpg
- create thumbnails for each jpg and store them using the same filename but prefixed with "tb_" resulting in a filename like tb_44d0d32a83aaa_1.jpg
- save the filename into the database with a unique id
At first I thought it was the memory limit or the post max size, but raising them to 30M did not help. Then I wrote a script to handle multiple uploads without resizing & database interaction. With this script I was able to:
- successfully upload a 15M file
- successfully upload 10+ images
I hope some of you see where the problem resides, or post me some cleaner code that does about the same.
thx in advance

here's the code:
Code: Select all
<?php
// database configuration & variable "$images_dir"
include("config.inc.php");
// initialization
$result_final = "";
$counter = 0;
// List of our known photo types
$known_photo_types = array(
'image/pjpeg' => 'jpg',
'image/jpeg' => 'jpg',
);
// GD Function List
$gd_function_suffix = array(
'image/pjpeg' => 'JPEG',
'image/jpeg' => 'JPEG',
);
// Fetch the photo array sent by preupload.php
$photos_uploaded = $_FILES['userfile'];
// Fetch the photo caption array
$photo_caption = $_POST['photo_caption'];
while( $counter <= count($photos_uploaded) )
{
if($photos_uploaded['size'][$counter] > 0)
{
if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types))
{
$result_final .= "File ".($counter+1)." is not a photo<br />";
}
else
{
mysql_query( "INSERT INTO gallery_photos(`photo_filename`, `photo_caption`, `photo_category`) VALUES('0', '".addslashes($photo_caption[$counter])."', '".addslashes($_POST['category'])."')" );
$new_id = mysql_insert_id();
$filetype = $photos_uploaded['type'][$counter];
$extention = $known_photo_types[$filetype];
$filename = uniqid("")."_1".".".$extention;
mysql_query( "UPDATE gallery_photos SET photo_filename='".addslashes($filename)."' WHERE photo_id='".addslashes($new_id)."'" );
// Store the orignal file
copy($photos_uploaded['tmp_name'][$counter], $images_dir."/".$filename);
// Let's get the Thumbnail size
$size = GetImageSize( $images_dir."/".$filename );
if($size[0] > $size[1])
{
$thumbnail_width = 250;
$thumbnail_height = (int)(250 * $size[1] / $size[0]);
}
else
{
$thumbnail_width = (int)(250 * $size[0] / $size[1]);
$thumbnail_height = 250;
}
// Build Thumbnail with GD 2.x.x, you can use the other described methods too
$function_suffix = $gd_function_suffix[$filetype];
$function_to_read = 'ImageCreateFrom' . $function_suffix;
$function_to_write = 'Image' . $function_suffix;

//

}
}
$counter++;
