Fatal error: Unsupported operand types in ...

Hi there -

I am a bit new to MediaWiki, but I have successfully installed a bunch of extensions. My LocalSettings.php has the proper include for Maps.php followed by my google and yahoo api keys.

The error I see is: Fatal error: Unsupported operand types in /home/me/public_html/extensions/Maps/Maps.php on line 174

I am running MediaWiki v1.15.1 and trying to install Maps v0.7.2 (w Validator v0.4.2 that came bundled). As far as I can tell these versions should work together.

Any ideas?

I'd guess this is some PHP version issue. What version are you using?

Also, can I see the error somewhere online?

Yea, I am using:

PHP: 5.2.9 (cgi) MySQL: 5.0.91mm-log

I can't show this online because I need to have the site running, but the error message I posted is all that appears when the page loads.

Thanks for your help!

Not sure if this helps (you probably already knew this), but line 174 is the final line here:

       $wgExtraNamespaces += array(
              	Maps_NS_LAYER => 'Layer',
              	Maps_NS_LAYER_TALK => 'Layer talk'
       );

That's odd... PHP 5.2.9 should support += for arrays. Anyway, this code is synonymous, so will probably get rid of the issue for you:

       $wgExtraNamespaces = array_merge( $wgExtraNamespaces, array(
              	Maps_NS_LAYER => 'Layer',
              	Maps_NS_LAYER_TALK => 'Layer talk'
       ) );

Hey everyone,

I also get the message "Fatal error: Unsupported operand types in /home/me/public_html/extensions/Maps/Maps.php on line 174 " like KBurns.

When I change the Code to:

$wgExtraNamespaces = array_merge( $wgExtraNamespaces, array(
             	Maps_NS_LAYER => 'Layer',
             	Maps_NS_LAYER_TALK => 'Layer talk'
      ) );

Then I get a new error:

Warning: array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #1 is not an array in /www/htdocs/***/***/extensions/Maps/Maps.php on line 174

Error in line 174‎

Can you do the following?

Add this code just before the code in question: var_dump($wgExtraNamespaces);exit;
Hit your wiki (which should not show)
View page source, copy what's there and post it here
Remove the above code (so your wiki is usable again)

That'll give me a better idea of what's going wrong.
