#2227 [3863] Undefined index in Gallery2

[David Richmond]

The following errors now occur when Gallery2 is launched from the taskbar:

ERROR 8: Undefined index: scheme

I think most of the problems connected with launching Gallery2 are related to G2EmbedDiscoveryUtilities.class. I've now hard wired the locations in pgv.php and all seems to work as expected.

[Greg Roach]

Which locations did you hard-wire?

Is it something that needs to be submitted back to the code?

I don't think any of the current developers use Gallery2, so we can't easily investigate.

Greg,

I found a 'solution' to the problem in an old thread [<<No images show up in Gallery2 !>><<By: Ray (raysur) - 2007-08-15 22:04>>]and everything now works (even if it is by coincidence!).

I changed both lines [72 & 73] in pgv.php for embedUri and g2Uri to the actual locations:

---------------------------------------------------------------------------------------
$init = GalleryEmbed::init(array(
'embedUri' => "/dbxs/index.php?mod=gallery2",
'g2Uri' => "/dbxs/modules/gallery2/",
'activeUserId' => $uid,
'activeLanguage' => $language_settings[$LANGUAGE]['lang_short_cut'],
'apiVersion' => array(1, 1)
---------------------------------------------------------------------------------------

Also in the modules area is a documented display problem regarding the style sheets for punbb using IE6 and concerns lines 22 and 23 which I changed to:

/* IEWin Font Size only - to allow IEWin to zoom. Do not remove comments \*/
* HTML body{font-size: 62.5%}
* .pun, .pun INPUT, .pun SELECT, .pun TEXTAREA, .pun OPTGROUP {
* font-family: Verdana, Arial, Helvetica, sans-serif;
* font-size: 1.1em;
* }
/* End IE Win Font Size */

I don't claim to understand it; but it seems to work!

[Greg Roach]

From your changes, I guess the real issue is that the code assembles a URL, but forgets the path. i.e. it assumes your installation is in http://www.example.com/ instead of http://www.example.com/path/

Perhaps change line 69 to include something like:
$bits['path']
or
dirname($bits['path'])

If this works, it would be a more correct/portable solution.

[David Richmond]

The $bits['path'] attempt gave the same errors as above.
I've no idea how to enter the other string without parse errors etc. (It would probably help if I could READ this stuff.)
I think it's probably only one part of the equation anyway as it has to be assembled in G2EmbedDiscoveryUtilities.class?
I tried to READ this file too; but I think it's in Cantonese?
