Thumbnail creation on the fly from db (Problem)

AlienOne

Hi can tell what i'm doing wrong in this code 🙂

$conn = mysql_connect("*", "*", "*")
OR DIE (mysql_error());
@mysql_select_db ("blob", $conn) OR DIE (mysql_error());
$sql= "SELECT * FROM binary_data WHERE id=8";
$result = mysql_query ($sql, $conn);
if (mysql_num_rows ($result)>0) {
$row = @mysql_fetch_array ($result);
$image_type = $row["filetype"];
$image = $row["bin_data"];
$p = 0.5;

$src_img = imagecreatefromstring($image); 

$width = imagesx($src_img);
$height = imagesy($src_img);

$dest_width = $width * $p; 
$dest_height = $height * $p; 

$dest_img = imagecreatetruecolor($dest_width, $dest_height); 

imagecopyresampled($dest_img, $src_img, 0 ,0 ,0 ,0 , $dest_width, $dest_height, $width, $height) // resize the image 

ob_start();
ImageJPEG($dest_img);
$thumbnail=ob_get_contents();
ob_end_clean(); 

header("Content-type: $image_type");
echo $thumbnail;
}

Hmm, in all my time programming PHP, I've not seen it issue that string as an error message. :eek: As someone once said, "our mindreader is down today...." 😃

Is there any diagnosis of the problem that you might care to share, or do you just expect everyone to read your mind? Be careful, or Drakla may post in your thread! :evilgrin:

Get on the stick, read Debugging 101 (linkage in my .sig). Do you own debugging, and come back with your findings. I for one find it interesting that you think that database calls are the only things that might possibly return a zero status.

For goodness sake guys, he didn't even mention what's wrong.....
