Will nested IF statements work?

[brad-t]

I'm using this in usercp_nav to display two different menus depending on which page you are viewing. The if statements for the CSS classes and inbox unread count were working before being nested in another IF -- is this a problem? Are nested IF disallowed?

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

<!-- User CP Menu --> <if THIS_SCRIPT == "usercp.php" then> <div class="cp_menu"><a href="/usercp.php"<if $mybb->input['action'] == '' || $mybb->input['action'] == 'changename' || $mybb->input['action'] == 'editsig' || $mybb->input['action'] == 'email' || $mybb->input['action'] == 'password' then> class="current"</if>>Profile & Settings</a> <a href="/usercp.php?action=editlists"<if $mybb->input['action'] == 'editlists' then> class="current"</if>>Friends and Foes</a> <a href="/usercp.php?action=drafts"<if $mybb->input['action'] == 'drafts' then> class="current"</if>>Drafts</a> <a href="/usercp.php?action=subscriptions"<if $mybb->input['action'] == 'subscriptions' then> class="current"</if>>Following</a> <a href="/User-{$mybb->user['username']}" style="float: right;">Go to profile ➜</a></div></if> <!-- Private Messages Menu --> <if THIS_SCRIPT == "private.php" then> <td valign="top" style="width: 200px; float: left; margin-right: 20px;"> <table border="0" cellspacing="0" cellpadding="0" class="insetbox messagenav" style="margin-bottom: 13px;"> <tr> <td style="padding: 0px;"> <a href="/private.php?action=send" class="button bigbutton" style="display: block;">New Message</a><br /> <if $mybb->user['pms_unread'] == 0 then> <a href="/private.php?fid=1" class="biglink <if $folder == 1 then>current</if>" style="display: block;">Inbox</a> <else> <a href="/private.php?fid=1" class="biglink <if $folder == 1 then>current</if>" style="display: block; font-weight: bold;">Inbox ({$lang->welcome_pms_usage})</a> </if> <a href="/private.php?fid=2" class="biglink <if $folder == 2 then>current</if>" style="display: block;">Sent</a> <a href="/private.php?fid=3" class="biglink <if $folder == 3 then>current</if>" style="display: block;">Drafts</a> <a href="/private.php?fid=4" class="biglink <if $folder == 4 then>current</if>" style="display: block;">Trash</a> <br /> <div class="smalltext"> <a href="/private.php?action=tracking" style="display: block;">Track Messages</a> <a href="/private.php?action=export" style="display: block;">Download Messages</a> <a href="/private.php?action=empty" style="display: block;">Empty Folders</a> </div> </td></tr> </table> </td> </if>
