thankyou

this is looking promising

i have tried the whole code and it didnt work. are you able to give me some hints as to how to introduce the PHP to the plan image field? DO you do it via the source button on the editor?
Which parts of this code are / are not required?

Code:

<!--?php
//Set the Content Type
header('Content-type: image/jpeg');


// Create Image From Existing File
$jpg_image = imagecreatefromjpeg(membershipcard.jpg');

// Allocate A Color For The Text
$white = imagecolorallocate($jpg_image, 255, 255, 255);
$black = imagecolorallocate($jpg_image, 0, 0, 0);

// Set Path to Font File
$font_path = 'swiss.ttf';
$fontsize = 8;

// Set Text to Be Printed On Image
$text1 = "Test HKPA membership card";
$text2 = "TEST HKPA MEMBERSHIP CARD TWO";

// Print Text On Image size, angle, left offset 0=left, vert offset 0=top
imagettftext($jpg_image, $fontsize, 0, 10, 20, $black, $font_path, $text1);
imagettftext($jpg_image, $fontsize, 0, 10, 30, $black, $font_path, $text2);

// Send Image to Browser
imagejpeg($jpg_image);

// Clear Memory
imagedestroy($jpg_image);
?>

thanks again for all the help

You need to review the plans image field to see how it pulls a users active subscriptions. You can then use that plan information to add to the image. A database query would probably work fine too depending on what you need.

You're already using the appropriate function to add text to the image. If it's not showing up then you probably have the coordinates wrong, the font path is incorrect, or maybe the other variables are invalid, but that's the right function.

As for grabbing a users active subscriptions the below will do just that.

Code:

$subscriptions = cbpaidSomethingMgr::getAllSomethingOfUser( $user );

if ( $subscriptions ) foreach ( $subscriptions as $type ) {
	foreach ( array_keys( $type ) as $typeId ) {
		$subscription = $type[$typeId];
		$plan = $subscription->getPlan();
	}
}

For this to work you need to have CB API available and prepare a CB user object. Both of which are explained in the below tutorials.

i have just tried some changes to the code, but it doesnt work still:

Code:

<?php
//Set the Content Type
header('Content-type: image/jpeg');

// Create Image From Existing File
$jpg_path = JURI::Root().'images/membershipcard.jpeg';
echo $jpg_path ; // THIS RETURNS       http://xxxx.net/images/membershipcard.jpeg
echo '</p>';
$jpg_image = imagecreatefromjpeg($jpg_path);

// Allocate A Color For The Text
$white = imagecolorallocate($jpg_image, 255, 255, 255);
$black = imagecolorallocate($jpg_image, 0, 0, 0);

// Set Path to Font File
$font_path = JURI::Root().'images/swiss.ttf';
$font_size = 8;
echo $font_path ; // THIS RETURNS       http://xxxx.net/images/swiss.ttf
echo '</p>';

// Set Text to Be Printed On Image
$text1 = "Test membership card";
$text2 = "TEST MEMBERSHIP CARD TWO";

// Print Text On Image size, angle, left offset 0=left, vert offset 0=top
imagettftext($jpg_image, $font_size, 0, 10, 20, $black, $font_path, $text1);
imagettftext($jpg_image, $font_size, 0, 10, 30, $black, $font_path, $text2);

// Send Image to Browser
imagejpeg($jpg_image);

// Clear Memory
imagedestroy($jpg_image);

?>

do you think the font path and the image path correct? the echo'ed out info seems correct? any other ideas?

I suggest reviewing the below in CB Captcha to see how we generate PHP GD images.
