I am attemptting to attach a small CMS to a website I am creating.

I am attemptting to attach a small CMS to a website I am creating. However I have come across a small problem. The CMS uses PHP functions for inserting menus, these PHP functions create the HTML. The particular function I wish to use (treemenu) creates a nested ul li that can then be used for a drop down menu. However the nested ul li is structured like so:

<li>Projects (Menu Level 1)</li>     <ul>         <li>Project 1 (Menu Level 2)</li>         <li>Project 2 (Menu Level 2)</li>         <li>Project 3 (Menu Level 2)</li>     </ul> <li>News (Menu Level 1)</li> <li>Contact (Menu Level 1)</li>

When creating a drop down menu in CSS I believe the Menu Level 1 li should wrap its children like so:

<li>Projects (Menu Level 1)     <ul>         <li>Project 1 (Menu Level 2)</li>         <li>Project 2 (Menu Level 2)</li>         <li>Project 3 (Menu Level 2)</li>     </ul> </li> <li>News (Menu Level 1)</li> <li>Contact (Menu Level 1)</li>

I have never before worked with PHP and therefore would not know how to alter the function in order to accomplish the above. I would hope it would be a simple change. Below is the PHP function that outputs the first example structure:

function treemenu($generat=0) { global $pagenum, $menu, $selected, $extension, $set; $count=0; $out='\n'; $intend=0; while($menu[$count][0] != '') {     if(strpos($menu[$count][3],'#') === false) {     if($menu[$count][2]=='0' && $intend==2) {         $intend--;         $out.='</ul>\n';     }     if($menu[$count][1]=='0' && $intend==1) {         $intend--;         $out.='</ul>\n';     }     if($menu[$count][1]!='0' && $intend<1) {         $intend=1;         $out.='<ul>\n';     }     if($menu[$count][2]!='0' && $intend<2) {         $intend=2;         $out.='<ul>\n';     }     $out.='<li class=\'LNE_menu\'><a ';     if($menu[$count][4]==$selected['name'])         $out.= 'class='selected' ';     if(strpos($menu[$count][3],'*'))         $out.='href=''.str_replace('*', '',$menu[$count][3]).''>';     elseif($generat)         $out.='href=''.$menu[$count][3].'.'.$set['extension'].''>';     else         $out.='href=''.$set['indexfile'].'?page='.$menu[$count][3].''>';     $out.=$menu[$count][4].'</a></li>\n';     }     $count++; } return $out; }

Could anyone possibly point me in the right direction as to how to make the closing li tag of a level 1 menu item wrap the ul immediately after, as in the second example?

  1. This would be a excellent example of the use of recursion. An array (with sub-arrays within it) defines each level, and a function loops, calling itself whenever it finds a new array to process. As long as the function cleans up appropriately (closing the </li> & </ol>), it’s largely automatic.

    <?php // I know which function I'd rather write.... $tree = array('Projects (Menu Level 1)',               array('Project 1 (Menu Level 2)',                     'Project 2 (Menu Level 2)',                     'Project 3 (Menu Level 2)'),               'News (Menu Level 1)',               'Contact (Menu Level 1)');  // now quake beneath the power of this fully operational recursive function! function olLiTree($tree) {     echo '<ul>';     foreach($tree as $item) {         if (is_array($item)) {             olLiTree($item);         } else {             echo '<li>', $item, '</li>';         }     }     echo '</ul>'; } olLiTree($tree);  // kick off from the top level
