PHP Dynamic Count & Limit Menu items
- by Adrian M.
Hello,
I want to modify this code which works pretty good but (or I don't know because I'm new with php) I can't limit the number of li's displayed for the main elements in the menu. The actual code will echo all elements it finds, I want to limit the times
<li><a href='{$sLink}' {$sOnclick} target='_parent'>{$sPictureRep}{$sText}</a>
this line is echoed.. let's say to echo just the first 15 elements + a "MORE" button under which to display the rest of the elements as sub-menus.. (this is a 2 level horizontal menu). Can someone please help me? I really tried a lot but I'm not an expert in PHP..
Thanks!
