Trouble With GD

[fire_cracker]

I am attempting to make a counter using GD v2.0. I have everything working, right up to when it is supposed to show the image. It is pulling information out of the database, and updating it with the new count, but I am getting the missing image box instead of the counter. I have been looking through this code endlessly, and I can't find any problem with it. I'm hoping a set of fresh eyes will do the trick.

Here is the code that is getting called:

<?php
$include_dir = $_SERVER['DOCUMENT_ROOT'] . "/fms/includes/";
$include_config = $include_dir . "config.php";
$include_sql = $include_dir . "sql_connect.php";
require($include_config);
require($include_sql);
$id = $_GET['id'];
$result = mysql_query("SELECT * FROM bcd_counter WHERE id='$id'") or die(mysql_error());
$row = mysql_fetch_array($result);
$counter = $row['counter'];
$font_num = $row['font_num'];
$br = $row['br'];
$bg = $row['bg'];
$bb = $row['bb'];
$fr = $row['fr'];
$fg = $row['fg'];
$fb = $row['fb'];
$counter++;
$result = mysql_query("UPDATE bcd_counter SET counter='$counter' WHERE id='$id'") or die(mysql_error());
while(strlen($counter) < 6) {
  $counter = "0" . $counter;
}
$font_dir = $_SERVER['DOCUMENT_ROOT'] . "/gdf/";
$font_type[1] = "04b.gdf";
$font_type[2] = "almosnow.gdf";
$font_type[3] = "anonymous.gdf";
$font_type[4] = "automatic.gdf";
$font_type[5] = "azimov.gdf";
$font_type[6] = "betsy.gdf";
$font_type[7] = "borringlesson.gdf";
$font_type[8] = "bubblebath.gdf";
$font_type[9] = "checkbook.gdf";
$font_type[10] = "chinyen.gdf";
$font_type[11] = "christmaxlightoutside.gdf";
$font_type[12] = "crackman.gdf";
$font_type[13] = "crass.gdf";
$font_type[14] = "cry.gdf";
$font_type[15] = "ennobled.gdf";
$font_type[16] = "festival.gdf";
$font_type[17] = "scarabo.gdf";
$font_type[18] = "sfballoon.gdf";
$font_type[19] = "xtrusion.gdf";
$font_name = $font_dir . $font_type[$font_num];
$font = imageloadfont($font_name);
$fontWidth = imagefontwidth($font);
$fontHeight = imagefontheight($font);
$im = imagecreate(strlen($string) * $fontWidth, $fontHeight);
$background = imagecolorallocate($im,$br,$bg,$bb);
$drawfontcolor = imagecolorallocate($im,$fr,$fg,$fb);
imagestring ($im, $font, 0, 0, $counter, $drawfontcolor);
header ("Content-type: image/png");
imagepng($im);
imagedestroy($im);
?>

And here is the code that I am putting on the page.

Thank you guys for any help you can provide.

Maybe there's an error or a warning being generated that might help us, and we can't see it! Comment out your header() line, and add this to the top of your script:

ini_set('display_errors', 'On');
ini_set('display_startup_errors', 'On');
error_reporting(E_ALL);

EDIT: Also try adding 'or die()' statements to see if it's fouling up at one point or another, e.g.

$im = imagecreate(strlen($string) * $fontWidth, $fontHeight) or die('Cannot Initialize new GD image stream');

me too have the same problem, but only when opened from the web server.

i have a captcha class to prevent net robots filling registration forms automatically,
everything is fine on local host,
but shows only a image place holder after uploaded to the web server.

i used

<img src="captcha_class/captcha_call.php"> 

instead of creating a disk file.

can u help me...

Do a phpinfo() and look at the GD section...

depending on what function you're using (imagepng, imagejpeg, etc.) make sure it's listed as "Enabled" in the GD section.

I changed the error reporting as suggested, I tried adding the "or die" statements, but nothing is showing up, I'm still getting the little red x. I checked the php info, and I can use PNG images. In fact I have a script running very similar to this one that displays the style of the counter, but doesn't pull anything out of the database, and it is working fine. I am totaly confused on why this little thing won't work 🙁

Where does "$string" come from? It works for me if I change that to "$counter".

[fire_cracker]

Well, I just changed that, figuring it is the one thing I forgot...but I still dont' see an image.

Here's the code I tested with. The only changes I made are to fill in the data from the db, and the "$counter" var:

$font_num = 3; 
$br = 0xFF; 
$bg = 0x00; 
$bb = 0x00; 
$fr = 0x00; 
$fg = 0xFF; 
$fb = 0x00; 
$counter = '123456'; 
$font_dir = $_SERVER['DOCUMENT_ROOT'] . "/gdf/"; 
$font_type[1] = "04b.gdf"; 
$font_type[2] = "almosnow.gdf"; 
$font_type[3] = "anonymous.gdf"; 
$font_type[4] = "automatic.gdf"; 
$font_type[5] = "azimov.gdf"; 
$font_type[6] = "betsy.gdf"; 
$font_type[7] = "borringlesson.gdf"; 
$font_type[8] = "bubblebath.gdf"; 
$font_type[9] = "checkbook.gdf"; 
$font_type[10] = "chinyen.gdf"; 
$font_type[11] = "christmaxlightoutside.gdf"; 
$font_type[12] = "crackman.gdf"; 
$font_type[13] = "crass.gdf"; 
$font_type[14] = "cry.gdf"; 
$font_type[15] = "ennobled.gdf"; 
$font_type[16] = "festival.gdf"; 
$font_type[17] = "scarabo.gdf"; 
$font_type[18] = "sfballoon.gdf"; 
$font_type[19] = "xtrusion.gdf"; 
$font_name = $font_dir . $font_type[$font_num];
$font = imageloadfont($font_name); 
$fontWidth = imagefontwidth($font);
$fontHeight = imagefontheight($font); 
$im = imagecreate(strlen($counter) * $fontWidth, $fontHeight); 
$background = imagecolorallocate($im,$br,$bg,$bb); 
$drawfontcolor = imagecolorallocate($im,$fr,$fg,$fb); 
imagestring ($im, $font, 0, 0, $counter, $drawfontcolor); 
header ("Content-type: image/png"); 
imagepng($im); 
imagedestroy($im);

I played with it some and I am not getting it to work, and thus I am thinking it is a server issue of some sort (my host tends to cause quite a few of them). So I will phone in to Tech Support and make some poor little Canadian fix it.

Congrats on the 1000th post Installer. What part of Iowa you from? I'm currently located outside of the Quad Cities.

[Installer]

I'm in Dubuque, not too far north of where you are.

my prioblem solved, i used imagecreate() instead of imagecreatetruecolor(),
since imagecreatetruecolor() is supported by GD 2.0 or higher, and our server was running with a lower version.
