thumbnail generating

[rpsep2]

Ive got some code and a from currently that allow users to upload an image. this image is stored into a folder in my sites root and the filepath to it is stored in a database table along with various other relevant info.

I would like a bit of code that also generates a thumbnail of a given size from this upload and stores it in a thumbnail folder, and also inputs the thumbnail filepath into the database table.

I don't really know where to start... if it helps, here is my upload form code (database connection etc happens before this):

<?

//set up the max filesize ppl can use and add a message variable to display and error type message if someone exceeds the limit. filesize is in bytes, 1mb= 104857 bytes
$maxFileSize=2000000000;
$message="";


//BEGIN FORM SUBMISSION CODE BOII
//these create the variables that we will call on to display later
$imgFileName=$_FILES['imgFile']['name'];
$imgFileTmp=$_FILES['imgFile']['tmp_name'];
$imgFileSize=$_FILES['imgFile']['size'];
$imgFileType=$_FILES['imgFile']['type'];
//END THE FORM SUBMISSION	


//if statement for recognising and then displaying and error message when the filesize is higher than the max filesize limit
if($imgFileSize > $maxFileSize){
	$message="You're doing it all wrong <br/>";
}


//if statement which looks for the right filetypes, if the wrong filetype is found it  displays another message
if($imgFileType=="image/jpeg"|| $imgFileType=="image/gif"){

}else{
$message.="Upload the right filetype you muppet<br/>";	
}

//this checks if the filename already exists and echos a message if it has
if(file_exists($filepath)){
	$message=" You already done uploaded it you plonka <br/>";
}


//this stops any error messages being shown if their are no issues
if(!isset($imgFileTmp)){
	$message="";
}

//if the message is empty, it will upload the file
if($message==""){
	move_uploaded_file($imgFileTmp,$filepath);
}

// this tells it to actually upload & where to upload the file to
$filepath="uploads/".$imgFileName;
move_uploaded_file($imgFileTmp,$filepath);

?>

styling bits n bobs go here
<?
//Check to see if the form has been submitted
		if(isset($_POST['button'])){

		// add the data from the fields into variable so i can use them later
		$username = ($_SESSION['userid']);
		$title = ($_POST['title']);
		$description = ($_POST['description']);
		date_default_timezone_set('Europe/London');
		$date = date("y-m-d, H:i:s");



		//check to see if any of the boxes were not filled in
		if(!$title|| !$description){
			//if any weren't display the error message
			$message=" You need to fill in all of the fields! <br/>";;
		}else{


 //if not.. go ahead and insert all the info into the sql database

 mysql_query("INSERT INTO uploads (username, title, description, filepath, date) 
VALUES ('$username', '$title', '$description', '$filepath', '$date')")or die(mysql_error());


 //display the success message
$message=" You have successfully uploaded a something! <br/>";
$message2=" Please follow the link below to view the full article<br/>";
?>

I'm using a pretty standard form with an upload button and a couple fields for a description and title. If any one could point em in the right direction or suggest a tutorial I'd appreciate it

ive tried a couple things as suggested but I cant get it to work, ive added:

<?								
$image=imagecreatefromjpeg($filepath);

list($width, $height) = getimagesize($image);

$new_width = 200;
$new_height= 150;

$image_p=imagecreatetruecolor($new_width, $new_height);

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Save the image
imagejpeg($image_p, '/thumbs'.$filepath);

// Free up memory
imagedestroy($image_p);
?>

where $filepath is the image being uploaded (this original upload part of the code works fine still)

then created the thumbs folder inside uploads and gave it write permissions.

where am I going wrong?

the problem is in this code

imagejpeg($image_p, '/thumbs'.$filepath);

So... does that mean you've resolved the issue? It does seem like the problem was with that statement; specifically, a path beginning with '/thumbs' means that you're telling PHP there is a 'thumbs' folder in the root of the server's hard drive. I'm guessing this isn't true.

And if you haven't resolved this, then you might want to let us know what "cant[sic] get it to work" actually means. Are you getting any PHP error messages? (Do you even have them enabled and/or are you even checking for them?)

yep all sorted now, i was using '/thumbsFILENAME' when it should have been thumbs/FILENAME, i.e put the file inside 'thumbs' folder whereas i was telling it to look for a folder called thumbsFILENAME i believe.

a silly syntax mistake on my part!
