不同页面的WordPress自定义菜单

Question

I am trying to use a custom menu on my landingpage.

I used this code:

<?php
function change_wp_nav_menu_args($args = ''){
    $pageID = get_the_id();
    if($pageID == '63') //custom menu for site with id 63
    {
        $args['menu'] = 'homepage';
    }
    return $args;
}
add_filter( 'wp_nav_menu_args', 'change_wp_nav_menu_args' );
?>

It works fine, but not only the main menu changes. The footer menu changes also. But the footer menu should be the same on every page.

How can I affect this?

Answer 1

This code fixed my problem:

<?php
        add_filter( 'wp_nav_menu_args', 'bb_wp_nav_menu_args' );
            function bb_wp_nav_menu_args( $args = '' ) {
                // change the menu in the Header menu position
                if( $args['theme_location'] == 'primary' && is_page('63') ) { 
                    $args['menu'] = '6'; // 32 is the ID of the menu we want to use here
                }
                return $args;
            }
    ?>

Its great that you find your answer, but it's a suggestion to make the code dynamic rather set the menu value as static [ $args['menu']='6' ].

Suggestion :

Create a Meta Box [ Dropdown with list of menu ] for Page with the Label Menu. And use the Menu Id for the wp_nav_menu .

For Dropdown [ listing Menus ]

function your_menus()
{
    $menu_arr=NULL;
    $menus=get_terms( 'nav_menu', array( 'hide_empty' => true ) );
    $menu_arr['your-nomenu']='Default';
    foreach ( $menus as $menu ){
        $menu_arr[$menu->slug]=$menu->name;
    }
    return $menu_arr;
}//end of function

For Nav Menus : [ _your_page_menu : meta name ]. You can place the code inside a function and called it in Header or you can place this code directly into the header.

     $page_menu_name=get_post_meta(get_the_ID(),'_your_page_menu',true)==''?'your-nomenu':get_post_meta(get_the_ID(),'_your_page_menu',true);
                if($page_menu_name==='your-nomenu')
                {
                    wp_nav_menu(array('theme_location'  => 'primary','menu_id'=> 'main-menu','container'=>false,'fallback_cb'=>'','menu_class'=>'main-navigation'));
                }
                else
                {
                    wp_nav_menu(array('menu_id'=> 'main-menu' , 'container'=>false, 'menu'=>$page_

menu_name,'fallback_cb'=>'','menu_class'=>'main-navigation'));
            }

Hope it helps you.
