Help with Upload with the GD library prob silly mistakes

[steve490]

Hey guys,

 

Heres the problem... Im trying to upload an image with my uploader (this works fine) but im having problems with the GD library trying to create thumbnails but I've never used the library before so having problems getting an output. I've tried echoing the GD code to find the problem but i get nothing returned. Can someone explain what i've done wrong and how to resolve the issue. All the folders and directories are in the right place and the images are being uploaded into the 'uploads' folder but not the 'thumbs' folder.

 

Heres all the code:-

 

 

 

$pic=($_FILES['name']);
$imagefolder='/';
$thumbsfolder='/';
$pics=directory($imagefolder,"jpg,JPG,JPEG,jpeg,png,PNG");
$pics=ditchtn($pics,"tn_");
$files = directory("/","jpg,gif");
$name='/uploads';		//Original filename
$filename='/thumbs';	//Filename of the resized image
$new_w = '100'; 
$new_h = '100';


$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');

$dbname = '****';
mysql_select_db($dbname);

$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

$pic = ($_FILES['uploadedfile']['name']);

mysql_query ("INSERT INTO img (name, email) VALUES ('uploads/$pic','$_SESSION[email]')");  

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded to" . $target_path;
} else{
    echo "There was an error uploading the file, please try again!";
}

if ($pics[0]!="")
{
foreach ($pics as $p)
{
	createthumb($p,"tn_".$p,150,150);
}
}

/*
Function ditchtn($arr,$thumbname)
filters out thumbnails
*/
function ditchtn($arr,$thumbname)
{
foreach ($arr as $item)
{
	if (!preg_match("/^".$thumbname."/",$item)){$tmparr[]=$item;}
}
return $tmparr;
}


function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(".",$name);
if (preg_match("/jpg|jpeg/",$system[1])){$src_img=imagecreatefromjpeg($name);}
if (preg_match("/png/",$system[1])){$src_img=imagecreatefrompng($name);}
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y) 
{
	$thumb_w=$new_w;
	$thumb_h=$old_y*($new_h/$old_x);

}
if ($old_x < $old_y) 
{
	$thumb_w=$old_x*($new_w/$old_y);
	$thumb_h=$new_h;
}
if ($old_x == $old_y) 
{
	$thumb_w=$new_w;
	$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
if (preg_match("/png/",$system[1]))
{
	imagepng($dst_img,$filename); 
} else {
	imagejpeg($dst_img,$filename); 
}
imagedestroy($dst_img); 
imagedestroy($src_img); 
}


function directory($dir,$filters)
{
$handle=opendir($dir);
$files=array();
if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}}
if ($filters != "all")
{
	$filters=explode(",",$filters);
	while (($file = readdir($handle))!==false)
	{
		for ($f=0;$f<sizeof($filters);$f++):
			$system=explode(".",$file);
			if ($system[1] == $filters[$f]){$files[] = $file;}
		endfor;
	}
}
closedir($handle);
return $files;
}

 

Im a novice with php so im still trying to understand how most things work and get rid of the silly mistakes I keep making.

Thanks for the help
