But the front end stil ends up with the following error:

Notice: Undefined variable: gd_support in C:\web\vrijdag.be\wwwroot\fotoshop\plugins\content\jwsigpro.php on line 100

you can check it live on www.vrijdag.be/fotoshop

I erased that part in the code and it seems to work fine :-|

At line 75 of the plugin just change the
if(!function_exists("gd_info")) {
to
if(function_exists("gd_info")) {

Thank you

I am getting the same error on the standard version (not the pro version):
Notice: Undefined variable: gd_support in .../oldnellynew.com.au/www/plugins/content/jwsig.php on line 83

Code on line 83 is:
if(count($gd_support)) {
foreach ($gdsupport as $k=>$v) {echo $v;}

Running Joomla! 1.5.9
The component is functioning reasonably well, I have a small layout issue but it may be completely unrelated. Any resolution for the error displayed would be great?

Hi!

In the code, between the lines 74 to 86, can you see the follow code?
// GD2 Library Check
if(function_exists("gd_info")) {
   $gdinfo = gd_info();
   $gdsupport = array();
   $version = intval(ereg_replace('[[:alpha:][:space:]()]+', '', $gdinfo['GD Version']));
   if($version!=2) $gdsupport[] = '<div class="message">'._SIGPRO_GD_LIBMISSING.'</div>';
   if (!$gdinfo['JPG Support']) $gdsupport[] = '<div class="message">'._SIGPRO_GD_LIBNOJPG.'</div>';
   if (!$gdinfo['GIF Create Support']) $gdsupport[] = '<div class="message">'._SIGPRO_GD_LIBNOGIF.'</div>';
   if (!$gdinfo['PNG Support']) $gdsupport[] = '<div class="message">'._SIGPRO_GD_LIBNOPNG.'</div>';
   if(count($gd_support)) {
	foreach ($gdsupport as $k=>$v) {echo $v;}
   }
}
It's strange because the $gd_support is initialized at line 77
Let's try this

Change
if(count($gd_support)) {
	foreach ($gdsupport as $k=>$v) {echo $v;}
}
to
if(isset($gd_support) && count($gd_support)) {
	foreach ($gdsupport as $k=>$v) {echo $v;}
}

Thank you!

Hi,
no $gd_support isn't initialized, but $gdsupport is (note the underscore)

Your isset solution won't really help, since there's no $gd_support the if() can't possibly be true regardless of GD2 working or not.

It's simply a typo, try to change
if(count($gd_support)) {

to
if(count($gdsupport)) {

and it should work as expected.

Cheers, Mario
