Hack: Add optional headings for lists

The following additions provide headings for any list that displays results. This can be useful since it avoids trying to test for results in a template (which is very difficult to do).

The following has been tested on the version of DPL which works with MW 1.16.

<?php
 
//etc...
        $sStartList = '<ul>';
        $sEndList = '</ul>';
        $sStartItem = '<li>';
        $sEndItem = '</li>';
 
        $sStartHead = '';
        $sEndHead = '';
        $sTextHead = '';
 
        $bUseGallery = false;
//etc....
 
                        case 'nofollow': # bug 6658
                                if ( 'false' != $sArg ) {
                                        $aLinkOptions['rel'] = 'nofollow';
                                }
                                break;
                        case 'headingtext':
                                $sTextHead = htmlspecialchars($sArg);
                                break;
                        case 'headingtag':
                                switch ($sArg)
                                {
                                case 'h2':
                                        $sStartHead = '<h2>';
                                        $sEndHead = '</h2>';
                                        break;
                                case 'h3':
                                        $sStartHead = '<h3>';
                                        $sEndHead = '</h3>';
                                        break;
                                case 'h4':
                                        $sStartHead = '<h4>';
                                        $sEndHead = '</h4>';
                                        break;
                                case 'h5':
                                        $sStartHead = '<h5>';
                                        $sEndHead = '</h5>';
                                        break;
                                case 'h6':
                                        $sStartHead = '<h6>';
                                        $sEndHead = '</h6>';
                                        break;
                                case 'br':
                                        $sStartHead = '<b>';
                                        $sEndHead = '</b><br />';
                                        break;
                                default:
                                        $sStartHead = '<b>';
                                        $sEndHead = '</b>';
                                        break;
                                }
                                break;                  
                } // end main switch()
 
//etc.....
 
        //start unordered list
        $output = $sStartHead.$sTextHead.$sEndHead.$sStartList . "\n";
 
//etc....
?>

This will provide headings for the ordinary lists, but not the gallery view.

The extra parameters are thus:

• headingtext - Text to use as a heading if results are found.
• headingtag - Tag to surround the heading text with. One of:
  • h2-h6 (headings 2 through 6)
  • b (bold)
  • br (bold followed by a br tag.

Example:

<DynamicPageList>
category    = Foo
headingtext = List of Foo
headingtag  = h2
</DynamicPageList>

Please note that the headings won't appear in the table of contents, regardless of which tag is used, but they will be formatted to appear laccording to the tag chosen.
