[Martinss]

Hello there!

My PHP skills are very poor, i'm trying to merge this two scripts for hours now. Can somebody merge them?

<?
include "config.php";

if (!isset($HTTP_POST_FILES['userfile'])) exit;

if (is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])) {

if ($HTTP_POST_FILES['userfile']['size']>$max_size) {
        echo "<center><br><br><br>Fails ir parak liels, ludzu samazini to!</center>"; exit; }
if(($HTTP_POST_FILES['userfile']['type']=="image/gif") || 
($HTTP_POST_FILES['userfile']['type']=="image/pjpeg") || ($HTTP_POST_FILES['userfile']['type']=="image/jpeg") || ($HTTP_POST_FILES['userfile']['type']=="image/png")) {

        if (file_exists("./".$path . $HTTP_POST_FILES['userfile']['name'])) {
                echo "<center><br><br><br>Bilde ar shadu nosaukumu jau eksistee! Nomaini nosaukumu un meegjini veelreiz!</center>"; exit; }

//generate random number
$zufall = time();
$fupl = "$zufall";
$nosaukums = $HTTP_POST_FILES['userfile']['name'];
$ext = substr(strrchr($nosaukums, '.'), 1);
$punkc = ".";
if (file_exists("./".$path .$fupl .$punkc .$ext)) {
                echo "<center><br><br><br>Bilde ar shadu nosaukumu jau eksistee! Nomaini nosaukumu un meegjini veelreiz!</center>"; exit; }
        $res = copy($HTTP_POST_FILES['userfile']['tmp_name'], "./".$path .$fupl .$punkc .$ext);
		        
        if (!$res) { echo "<center><br><br><br>Bilde ar shadu nosaukumu jau eksistee! Nomaini nosaukumu un meegjini veelreiz!</center>"; exit; } else {
        ?>
<br>

<?
//set url variable
$domst = "";
$drecks = "/";
$imgf = $fupl.$punkc.$ext;
$thbf = $tpath.$imgf;
$urlf = $domst .$domain .$drecks .$path .$imgf;


//create thumbnails
function createthumb($name,$filename,$new_w,$new_h){
	$system=explode('.',$name);

	if (preg_match('/jpg|jpeg|JPG/',$system[1])){
		$src_img=imagecreatefromjpeg($name);
	}
	if (preg_match('/png|PNG/',$system[1])){
		$src_img=imagecreatefrompng($name);
	}
	if (preg_match('/gif|GIF/',$system[1])){
		$src_img=imagecreatefromgif($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,$filename); 
} 
if (preg_match("/gif/",$system[1]))
{
	imagegif($dst_img,$filename);
}
else {
	imagejpeg($dst_img,$filename); 
}
imagedestroy($dst_img); 
imagedestroy($src_img); 
}

createthumb($path.$imgf,$tpath.$imgf,$tsize,$tsize);

?>

and this

$watermark = imagecreatefrompng('watermark.png');  
$watermark_width = imagesx($watermark);  
$watermark_height = imagesy($watermark);  
$image = imagecreatetruecolor($watermark_width, $watermark_height);  
$image = imagecreatefromjpeg($_GET['src']);  
$size = getimagesize($_GET['src']);  
$dest_x = $size[0] - $watermark_width - 5;  
$dest_y = $size[1] - $watermark_height - 5;  
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);  
imagejpeg($image);  
imagedestroy($image);  
imagedestroy($watermark);

Basicly it needs to watermark the little thumbnail. Any help?

Any help there? I've have made this, but a lot of errors.

imagedestroy($watermark);

Too much code and would need quite of time for anyone to find out what is happening

You can have a look at a wondeful class upload - it handles common image functions very easily.

http://www.verot.net/php_class_upload_download.htm

* It manages file uploads for you. In short, it manages the uploaded file,
* and allows you to do whatever you want with the file, especially if it
* is an image, and as many times as you want.
*
* It is the ideal class to quickly integrate file upload in your site.
* If the file is an image, you can convert, resize, crop it in many ways.
* You can also apply filters, add borders, text, watermarks, etc...
* That's all you need for a gallery script for instance.
*
* You can also use the class to work on local files, which is especially
* useful to use the image manipulation features
