Wordpress Menu Help

[Valiant]

I'm trying to make it so that a particular user role is shown a particular menu instead of the standard one on my site.


I want all users to see "Main Menu" as the primary menu. As they do now. But I want "wholesale_customer" to see "Wholesale" menu instead.


Here are the current registered menus

Code: [Select]

register_nav_menu('primary', __('Primary Menu', 'oxy'));
register_nav_menu('topnavhor', __('Top Horizontal Menu', 'oxy'));
register_nav_menu('topnav', __('Top Dropdown Menu', 'oxy'));

Here is the code I have

Code: [Select]

// Change main menu for Wholesale Customers
function my_wp_nav_menu_args( $args = ” ) {
if ($args[‘theme_location’] == ‘primary’) {
if( is_user_wholesale_customer()) {
$args[‘menu’] = ‘Wholesale’;
}else{
$args[‘menu’] = ‘Main Menu’;
}
}
return $args;
}
add_filter( ‘wp_nav_menu_args’, ‘my_wp_nav_menu_args’ );What's wrong with the code as I keep getting a Error 500 when add it to my child theme's functions.php file.

Ok so these might better a better way to do it, but they both give me a 500 error.

Code: [Select]

/* Menu swap out for Wholesale */


$user = wp_get_current_user();


if ( in_array( 'wholesale_customer', (array) $user->roles ) {
    wp_nav_menu( array( 'primary' => 'Wholesale' ) );


} else  {
     wp_nav_menu( array( 'primary' => 'Main Menu' ) );
} 

or this

Code: [Select]

       global $current_user;


        get_currentuserinfo();


        switch (true)  {
       
         case ( user_can( $current_user, "wholesale_customer") ):?>
           <?php wp_nav_menu( array( 'primary' => 'Wholesale' ) ); 
         break
         case ( user_can( $current_user, "customer") )?>
           <?php wp_nav_menu( array( 'primary' => 'Main Menu' ) ); 
         break;
          default:
          wp_nav_menu( array( 'primary' => 'Main Menu' ) );
          break;
        }

What's in the server logs?

Your first version has smart quotes in it, if those are in the actual file it's a syntax error.

I can't find anything in the error logs.

A 500 will have some output, somewhere. Have you tried the suggestions at the bottom of https://stackoverflow.com/questions/7576759/how-to-trace-what-is-causing-wordpress-error-500

Ah got the debug. I forgot that was turnt off my default.

Code: [Select]

[11-Feb-2018 10:09:35 UTC] PHP Parse error:  syntax error, unexpected 'case' (T_CASE) in ../functions.php on line 31
[11-Feb-2018 10:09:44 UTC] PHP Parse error:  syntax error, unexpected 'case' (T_CASE) in ../functions.php on line 31
[11-Feb-2018 10:09:46 UTC] PHP Parse error:  syntax error, unexpected 'case' (T_CASE) in ../functions.php on line 31


Which refers to

Code: [Select]

         case ( user_can( $current_user, "customer") )?>

Not my language, so not sure of the syntax, but:
The if statement I'm code1 is missing a closing brace.
The second case statement in code2 is missing a colon (before the question mark).

And the cause of the message is a missing semicolon on line 30.

I know this is a Wordpress thread, but I just wanted to say that after so may years with Wordpress and its endemic failings - for me anyway - I've given up and changed to WIX instead. So much easier for a non-HTML'r like me.

Hey thanks for this. Eventually this worked:

Code: [Select]

        global $current_user;
get_currentuserinfo();
switch (true) {
case ( user_can( $current_user, "wholesale_customer") ):
wp_nav_menu( array( 'primary' => 'Wholesale' ) );
break;
case ( user_can( $current_user, "Customer") ):
wp_nav_menu( array( 'primary' => 'Main Menu' ) );
break;
default:
wp_nav_menu( array( 'primary' => 'Main Menu' ) );
break;
}
However now getting errors with the header etc.

PHP Warning:  Cannot modify header information - headers already sent by (output started at .../wp-includes/nav-menu-template.php:256) in .../wp-includes/pluggable.php on line 1216

As well as various other warnings etc.
