Table issue with template and heading

Check the latest version of MediaWiki extension. Problem with table headers has been fixed today (#2044).

I believe that {{table}} can't appear after {|. I tried to add the following text

{| {{table}}
 ! A || B
 |-
 ! 1
 | 2
 |}

in MediaWiki Sandbox and the table template has been stripped as well, so the behaviour seems to be correct.

Hello,

thank you for the quick fix on table headers.

For embeding template in table syntax, please take a look at this wiki source http://www.mediawiki.org/wiki/Template:Tableheader

I also tried the following on the sandbox(http://www.mediawiki.org/wiki/Sandbox), and the template is applied properly

{| {{Tableheader}} ! A ! B |- |1 |2 |}

Thanks.

I'm attaching a patch. It relies on a hook that doesn't exist yet. With this patch, if template is inside of a tag, it is not surrounded by a <span> tag. It is also required to tell Sanitizer to not remove our special word that is replaced with the template content at the end of processing, that's why new hook is necessary.

In includes/Sanitizer.php, function fixTagAttributes, add this before the last line (with return statement):

if ( !wfRunHooks( 'SanitizerAfterFixTagAttributes', array( $text, $element, &$attribs ) ) ) {
	return '';
}

it should look similar to:

static function fixTagAttributes( $text, $element ) {
	if( trim( $text ) == '' ) {
		return '';
	}

	$stripped = Sanitizer::validateTagAttributes(
		Sanitizer::decodeTagAttributes( $text ), $element );

	$attribs = array();
	foreach( $stripped as $attribute => $value ) {
		$encAttribute = htmlspecialchars( $attribute );
		$encValue = Sanitizer::safeEncodeAttribute( $value );

		$attribs[] = "$encAttribute=\"$encValue\"";
	}
	if ( !wfRunHooks( 'SanitizerAfterFixTagAttributes', array( $text, $element, &$attribs ) ) ) {
		return '';
	}
	return count( $attribs ) ? ' ' . implode( ' ', $attribs ) : '';
}

Let me know if that worked for you.

Fixed with [1941].

#2147 marked as DUP.

Hook added to the core in MediaWiki 1.13 (r33726, r33725): https://bugzilla.wikimedia.org/show_bug.cgi?id=13821.
