How to add url prefix to a secondary menu? WordPress

Jeremy Phillips comments:

Thanks, I tested it but I'm not quite clear on how I should customize it for my needs. I want the marathon menu items to have 'marathon' in their url, so they appear like this:
www.my-site.com/marathon/page-name

John Cotton comments:

From what you said in your original post, something as simple as this would work:


$item->url = str_replace( 'my-site.com/', 'my-site.com/marathon/', $item->url);


but obviously you can add in whatever logic you want there...

Jeremy Phillips comments:

Is this the way that it should be implemented? This didn't seem to work.

function modifiy_nav_menu_items($items, $args) {
if( $args->theme_location == 'Marathon' ) {
foreach( $items as $item ) {
$item->url = str_replace( 'mysite.com/', 'mysite.com/marathon/', $item->url);
// change $item->url as you need to;
}
}
return $items;
}
add_action( 'wp_nav_menu_objects', 'modifiy_nav_menu_items', 10, 2 );


Thanks!

In what way didn't it work?

Jeremy Phillips comments:

I inserted the above code into my functions.php and tested the Marathon menu. Pages from that menu still lacked /marathon from their url.

John Cotton comments:

Apologies if this sounds daft, but can I take it that you replaced the "my-site" with the real site name?

Jeremy Phillips comments:

Yeah, and I tried with and without http:// on a couple sites no no avail.

John Cotton comments:

Well, there's three possibilities:

1/ The function is never being executed - you could pop a little echo in at the top to see whether it's being called
2/ The $args->theme_location isn't called 'Marathon' - have you tried lower case? It needs to precisely match whatever you declared when the menu was registered
3/ The urls you have in items don't have whatever you're looking for in them

So I would mod the code to this and see what happens:



function modifiy_nav_menu_items($items, $args) {
echo "modifiy_nav_menu_items called<br/>\n";
echo "location = ". $args->theme_location . '<br/>';

if( $args->theme_location == 'Marathon' ) {

foreach( $items as $item ) {
echo $item->url. '<br/>';
$item->url = str_replace( 'mysite.com/', 'mysite.com/marathon/', $item->url);

// change $item->url as you need to;

}

}

return $items;

}

add_action( 'wp_nav_menu_objects', 'modifiy_nav_menu_items', 10, 2 );



Jeremy Phillips comments:

The echo from the above code worked, although still no change to the url. I've been trying lowercase as well as uppercase.

Not sure I understand what you mean by this:
<em>3/ The urls you have in items don't have whatever you're looking for in them</em>

You're not giving me enough info - can you send me a link to the site?
