Not sure this is a bug, but....

I want to display the sub menu on the index page, but only for guests.  Logged in members wont get a sub menu.

To test, I modified BxBaseMenu.php   (added code in red)

        //--- Submenu Menu ---//
        $sSubMenu = '';
       if(!defined('BX_INDEX_PAGE') && !defined('BX_JOIN_PAGE'))
            $sSubMenu = $this->genSubMenus();

 if(!isMember() && (defined('BX_INDEX_PAGE'))) $sSubMenu = $this->genSubMenus();

        $sResult = $oSysTemplate->parseHtmlByName('navigation_menu.html', array(
            'main_menu' => $sMainMenu,
            'sub_menu' => $sSubMenu

It works, but only when the url is Mysite.com/index.php

When the url is simply Mysite.com, the sub menu container is present, but the sub menu is not generated.  Not a big deal because I can use a url rewrite to always add index.php  The only caveat of a Rewrite, is that you need to use a 301 redirect to keep search engines happy. It would be nice to be able to avoid all this.

I just wondered if I was missing anything.  I don't want site visitors to NOT see the submenu, if their entry point is mysite.com/

Looks to me its because of the lines above....Doesn't appear to be a bug but rather how the code is written to work. Maybe try removing these lines and see if it works. May be conflicting with the line you added.

if(!defined('BX_INDEX_PAGE') && !defined('BX_JOIN_PAGE'))

$sSubMenu = $this->genSubMenus();

 I don't think you understand the issue. There may not be a coding fix.  Simply put, PHP doesn't know apache is delivering index.php @ url mysite.com, so the constant 'BX_INDEX_PAGE' is not defined in that case.

Try this.

Edit BxBaseMenu.php

Look for this at about line 240

    /*
    * Generate sub menu elements
    */
    function genSubMenus()
    {
        foreach( $this->aTopMenu as $iTItemID => $aTItem ) {
            if( $aTItem['Type'] != 'top' && $aTItem['Type'] !='system')
                continue;

            if( !$this->checkToShow( $aTItem ) )
                continue;


Add this under it.

            if($this->aMenuInfo['currentTop'] == -1) $this->aMenuInfo['currentTop'] = 5;

 Perfect!  Thanks Deano   (I added the modified function to BxTemplMenu.php)

This is why you write code for a living, and I don't.  In another 5 years or so, I'll understand why that works.

That line should probably be added to the distribution, because even without what I added, anyone that wants to display the sub menu on the index page will have the same problem.

Things are looking up.  Got a sub menu on the index page for guests, and now I even have a blue Facebook button. What more could a person ask for?

 Don't yell at me! lol

 Where was I yelling?

 Relax junior...notice the lol on the end of my statement? :-)

 <lol>

OH.... 'lol'  .... I never really got into all that cool internet lingo, so I really don't pay much attention to it.

</lol>

 It's all good brother! Enjoy your evening.
