PHP: Uploading files to server

Right now I have a script that uploads and stores images in a database. I have been advised that uploading to my server would save resources and increase the speed in which the images are displayed. Is there an easy way to change what I have now to save to my server? I hate to paste a lot of code in a forum, but here I go. This is how I’m uploading my images to a database:

[code]if($_FILES[‘userfile1’][‘size’] > 0){
$limit_size = imageLimit();//file size limit
$fileName = $_FILES[‘userfile1’][‘name’];
$tmpName = $_FILES[‘userfile1’][‘tmp_name’];
$fileSize = $_FILES[‘userfile1’][‘size’];
$fileType = $_FILES[‘userfile1’][‘type’];

$fp = fopen($tmpName, ‘r’);
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);

if(!get_magic_quotes_gpc()){ $fileName = addslashes($fileName);}
switch($fileType) {
case ‘image/pjpeg’:
case ‘image/gif’:
case ‘image/x-png’:
case ‘image/bmp’:
echo “You selected an invalid image type. Please go back and try again.”;
$used=usedSpace();//amount of spaced used by a user
$added=$fileSize+$used;//used space plus current file
$allowed=diskSpace();//total space available to a user
if($fileSize > $limit_size)
echo “File $fileName’s size is over the limit”;
else if($added>$allowed)
echo “You do not have enough disk space to upload this image”;
else if(isset($extension)){
$query = "INSERT INTO image (image_id,image_name,image_size,image_type,image) ".
“VALUES (’$image1_id’,’$bill_id’,’$userKey’,’$fileName’,’$fileSize’,’$fileType’,’$content’)”;
mysql_query($query) or die(mysql_error());
else{ echo “failure?”; }

Thanks for the help guys!

Without going into a detailed analysis (I’m busy with Christmas prep!), you should be able to take advantage of the move_uploaded_file() function. There are some good file upload examples on the PHP site.

You’re best bet is probably the Uber-Uploader though.

You can refer this for example also
Hanlding file uploads

For the above example, you can change

$uploaddir = ‘/var/www/uploads/’;


$uploaddir = getcwd().’/’; // refer to current location

If you’re just uploading images, this might interest you.

I’ve been using it for a good 3 years now and it works a treat. It enables you to resize images either absolutely, or proportionally, and gives you some other nifty functionality using GDI (GDI2 i think).

I’ve used this and also combined it with a bit of extra code to overlay a watermark on the images.

I’ve done this in a few places, one of which is the “Paintings” section of The thumbs and the main images were all created with that script, and the “SAMPLE” overlay text with my own code (using imagecopymerge).

As usual, apologies if i’m ranting OT - just thinking it might be a useful suggestion if you need to do some image manipulation at upload time :slight_smile:
