Title: On php 8 or higher Undefined constant "IMG_GIF" error in "editshop"
Post by: EIF on March 05, 2023, 16:43:02 PM

On my test environment I just update from Joomla 3 to Joomla 4.2.8 and from Virtuemart 3 to Virtuemart 4.0.12 10777

When I go to "Shop" in Components/Virtuemart/Shop (url administrator/index.php?option=com_virtuemart&view=user&task=editshop) on PHP 7.4 there are no problems.
But when I switch to PHP 8.0 or 8.1, then the "0 Undefined constant "IMG_GIF" appears.

Code Select

Call stack
#	Function	Location
1	()	JROOT\administrator\components\com_virtuemart\helpers\mediahandler.php:437
2	VmMediaHandler->displaySupportedImageTypes()	JROOT\administrator\components\com_virtuemart\helpers\mediahandler.php:1415
3	VmMediaHandler->displayFileHandler()	JROOT\administrator\components\com_virtuemart\helpers\mediahandler.php:1107
4	VmMediaHandler->displayFilesHandler()	JROOT\administrator\components\com_virtuemart\views\user\tmpl\edit_vendor.php:65
5	include()	JROOT\libraries\src\MVC\View\HtmlView.php:410

Is that mediahandler.php file not updated? Or do I need some configuration else?

Who knows the solutions?

Never mind, I found the solution.

The PHP 8 didn't have GD library (extension=gd ) enabled. It is working now.
