Math formula issue in mediawiki+fckeditor

[kavine]

I want to use formula tools in my mediawiki. I integrate the fckeditor into mediawiki successfully. Then I install the math requirements, it do can render math images, but doesn't works well.

when I input a formula in the formular dialog, then submit, the math image doesn't show immediately, but a image placeholder. If I click the "wikitext" button, it seems work well with a conversion to real wikitext like "<math>formula</math>". Then click the "wikitext" button, the required math image turns out. The most important, while save this page, it becomes [[image:|formula]].

there must be a solution to this problem, for a successful example exists in "​http://mediawiki.fckeditor.net/index.php/Sandbox", it works quite well.

Is there any progress on this issue or news?

I am having the same issue here:

1) Add ''<math>e=mc^2</math>'' in FCKEditor (Edit Button)
2) Page displayed and rendered as: ''<img src='/bp/images/math/math-a43010f494bf0b6b8750078d33d00067.png' title='e=mc^2' alt='e=mc^2' class="tex">'' in HTML
3) Click Edit again and it is now rendered as ''[[Image:|e=mc^2]]'' in FCKEditor
4) Saving results in ''[[Image:|e=mc^2]]'' being displayed.

Check the latest version of extension, clear browser's cache and let me know if it works. If it still doesn't work, please provide more details about your MediaWiki configuration.

This issue still occurs when using:

• Mediawiki 1.13
• FCKEditor 2.6.4
• Revision #4355 of the extension.

The editor works correctly here: ​http://mediawiki.fckeditor.net/index.php/Sandbox, but that is:

• Mediawiki 1.11.2
• FCKEditor 2.5.1
• Unknown revision.

A possible fix is this, in FCKeditorParser.body.php, change:

	case 'math':
						if($wgUseTeX){		//show fakeimage
							$output = $wgContLang->armourMath( MathRenderer::renderMath( $content ) );
						}else				//normal render
							$output = '<img _fckfakelement="true" class="FCK__MWMath" _fck_mw_math="'.$content.'" src="'.$wgScriptPath.'/skins/common/images/button_math.png" />';
						break;

to

case 'math':
						if($wgUseTeX){		//normal render
							
						$output = '<img _fckfakelement="true" class="FCK__MWMath" _fck_mw_math="'.$content.'" src="'.$wgScriptPath.'/skins/common/images/button_math.png" />';
						}else				//show fakeimage
						$output = $wgContLang->armourMath( MathRenderer::renderMath( $content ) );	
						break;

Basically switch the then clauses. Not pretty, and not as it should be done, but it does fix the issue. FCKEditor now shows a <<math>> blok, which accepts right-click -> Edit formula

Thanks for your fix Doc. Still, it would be much better to actually see the image formulas instead of a <math> tag in fckeditor. I wish I could see the real image formulas, and not having those [[Image:]] issues.

I just went to your Sandbox, and as it is explained in the bug description, and it works well. How come? Should I reinstall FCKeditor? Is that a customized plugin version?
