thumb script

[1stMoogwai]

Hello. I have searched the thumbnail scripts and threads here and haven't found anything to point me in the right direction yet. I am having GREAT difficulties getting this script to work. THe full sized image upload is working... the thumbnail is NOT AT ALL. Any help would be greatly appreciated.

Thanks in advance,
1M.

	if (@$file) {
		//declare var for photo file name for db
		$photo_file = $file['name'];
		//sql
		$query = "	INSERT into photos (photo_file, photo_date, photo_desc) 
					VALUES ('$photo_file', '$date', '$desc')";
		$result = mysql_query($query, $conn) or die(mysql_error());


	//path name vars
	$abspath = $HTTP_SERVER_VARS['PATH_TRANSLATED'];
	$stub=ereg_replace("/photoAdd.php","/",$abspath);

	// use $fullname for the resulting path for file uploads, based on any changes you make above
	$fullname = $stub ."/images/photos/".$file['name'];
	$fullNameThumb = $stub ."/images/photos/thumbs/".$file['name'];

	// the following concerns image files...
	$size=getimagesize($file['tmp_name']);
	$area = $size[0]*$size[1];

	//copies full sized image
	copy($file['tmp_name'],$fullname);
	//copy($file['tmp_name'],$fullNameThumb);

	//begin thumbnail script
	$src_img=imagecreatefromjpeg($fullNameThumb); 
	$old_x=imagesx($src_img); 
	$old_y=imagesy($src_img); 
	$thumb_w=50;
	$thumb_h=50;
	$dst_img = imagecreatetruecolor($thumb_w,$thumb_h); 
	//echo $src_img;
	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
	//imagedestroy($dst_img); 
	//imagedestroy($src_img); 
}

Do you get any errors? Is there something in particular we should be looking for?

[1stMoogwai]

I should have posted that info in the first place.

Yes, there is an error in one case. Right now the line:

$src_img=imagecreatefromjpeg($fullNameThumb);_

Returns 4 errors. All stemming from the fact that it is not finding the file/path associated with $fullNameThumb. If I substitute $fullName for $fullNameThumb, there are no erros reported but the thumb script produces nothing.

I tried using the normal copy function with $fullNameThumb (you'll see it commented out) to try and create the image for temporary use in the thumb script... No luck.

I have checked and the GD library is installed and the proper version too, phpinfo();.

Let me know if you need more details,
Thanks again,

you're not outputing the image anywhere [man]imagejpg[/man]

Do I need to output the file? I am just looking to save it into the thumbnail directory. I placed the imagejpg into the script as such:

	if (@$file) {
		//declare var for photo file name for db
		$photo_file = $file['name'];
		//sql
		$query = "	INSERT into photos (photo_file, photo_date, photo_desc) 
					VALUES ('$photo_file', '$date', '$desc')";
		$result = mysql_query($query, $conn) or die(mysql_error());


	//path name vars
	$abspath = $HTTP_SERVER_VARS['PATH_TRANSLATED'];
	$stub=ereg_replace("/photoAdd.php","/",$abspath);

	// use $fullname for the resulting path for file uploads, based on any changes you make above
	$fullname = $stub ."/images/photos/".$file['name'];
	$fullNameThumb = $stub ."/images/photos/thumbs/".$file['name'];

	//copies full sized image
	copy($file['tmp_name'],$fullname);


	//begin thumbnail script
	$src_img=imagecreatefromjpeg($fullname); 
	$old_x=imagesx($src_img); 
	$old_y=imagesy($src_img); 
	$thumb_w=100;
	$thumb_h=100;
	$dst_img = imagecreatetruecolor($thumb_w,$thumb_h); 
	//echo $src_img;
	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
	imagejpeg($dst_img,"",90);
	//copy($dst_img,$fullNameThumb);
	imagedestroy($dst_img); 
	imagedestroy($src_img); 
	header("Location:photoAdmin.php"); 
}		

Now the thumb is being generated but not saved resized. Also the header line is being ignored and the page simply shows the thumb when submitted.

I'm at a loss,
Thanks for all your help,

I simply needed to add the 2nd argument into the imagejpg function:

	if (@$file) {
		//declare var for photo file name for db
		$photo_file = $file['name'];
		//sql
		$query = "	INSERT into photos (photo_file, photo_date, photo_desc) 
					VALUES ('$photo_file', '$date', '$desc')";
		$result = mysql_query($query, $conn) or die(mysql_error());


	//path name vars
	$abspath = $HTTP_SERVER_VARS['PATH_TRANSLATED'];
	$stub=ereg_replace("/photoAdd.php","/",$abspath);

	// use $fullname for the resulting path for file uploads, based on any changes you make above
	$fullname = $stub ."/images/photos/".$file['name'];
	$fullNameThumb = $stub ."/images/photos/thumbs/".$file['name'];

	// the following concerns image files...
	$size=getimagesize($file['tmp_name']);
	$area = $size[0]*$size[1];

	//copies full sized image
	copy($file['tmp_name'],$fullname);


	//begin thumbnail script
	$src_img=imagecreatefromjpeg($fullname); 
	$old_x=imagesx($src_img); 
	$old_y=imagesy($src_img); 
	$thumb_w=100;
	$thumb_h=100;
	$dst_img = imagecreatetruecolor($thumb_w,$thumb_h); 
	imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
	imagejpeg($dst_img,$fullNameThumb,90);
	imagedestroy($dst_img); 
	imagedestroy($src_img); 
	header("Location:photoAdmin.php"); 
}	

and now she works.

Thanks all,
1M.
