custom images using php gd library in oscommerce

[sonixtwo]

On my product_info.php page, I would like to show an image with the price overlayed onto it.

 

For this I am using the php gd library. The image is called by

 

product_info.php:

<?php echo tep_image(DIR_WS_IMAGES . 'custompic.php'); ?>

 

custompic.php consists of valid code to display what I need, but the value for $products_price is displayed as zero. I imagine it has something to do with the variables to calculate $products_price not being carried over to custompic.php. How can I resolve this?

 

Here is my custompic.php code:

<?php
header ("Content-type: image/png");
$im = imagecreatefrompng("coolbox.png");
$white = imagecolorallocate($im,255,255,255);
$blue = imagecolorallocate($im,0,0,255);
$red = imagecolorallocate($im, 255, 0, 0);
$black = imagecolorallocate($im, 0, 0, 0);
$px   = (imagesx($im)/2);
imagestring($im, 3, $px, 9, $products_price, $red);
imagepng($im);
imagedestroy($im);
?>

 

 

 

Any help would be appreciated. Thanks!

I have the idea to append the sid to the end of echo tep_image(DIR_WS_IMAGES . 'custompic.php') and the incude application_top to custompic.php. Hopefully this works.

 

Still hoping for some input. Thanks!

Just include the price as part of the url being called, so it looks like this:

 

<?php echo tep_image(DIR_WS_IMAGES . 'custompic.php?price=' . urlencode($products_price)); ?>

And this:

 

<?php
header ("Content-type: image/png");
$im = imagecreatefrompng("coolbox.png");
$white = imagecolorallocate($im,255,255,255);
$blue = imagecolorallocate($im,0,0,255);
$red = imagecolorallocate($im, 255, 0, 0);
$black = imagecolorallocate($im, 0, 0, 0);
$px   = (imagesx($im)/2);
$products_price = urldecode($_GET['price']);
imagestring($im, 3, $px, 9, $products_price, $red);
imagepng($im);
imagedestroy($im);
?>
