I want to restrict access of an user (ref. pic given)

• Title for your fault: Want to make a custom role to restrict an admin to access certain area
• Fault Description: I am unable to create a Custom Role with which I can restrict an admin to access certain areas in Admin Dashboard of WordPress.
• What have you done to try to fix the issue: I am not a coder but I do edit some code by Google-ing. I tried to make a MU-PLUGIN which remained unsuccessful. I tried to add functions in the site theme's functions.php file but could not make it work as per my desire.
• What I want to do: I am building a hotel website with wordpress. Now, I have to give my client the admin access to manage the booking and accommodation only because he is not a developer or designer. He is the owner-manager of his small hotel. So, if I give him full admin access, he will be overwhelmed and might mess up with the design and functionality of the website. To do that, I want all menus / options on the left side panel will be inaccessible and hidden except the booking and accommodation option. I prefer using a method which will not be destroyed / changed with the update of the theme. I have attached a screenshot with multicoloured markings and their explanations for better understanding. So far, I have successfully hide the rest of the menu / links / options on the left panel using some code in functions.php file of the theme I used but have failed to hide the red-marked area Can you guys help me? Please guide me.

Yes, you need to add code in functions.php of a CHILD THEME or you can use a Code Snippets plug-in.

What do you mean?

Of course you can give him a role and disable access to all menu items except Accommodation and Booking. This plug-in can do that:

As for the Dashboard and admin menu bar, here's the code to make it blank:

PHP:

show_admin_bar(false);

function customize_my_wp_admin_bar( $wp_admin_bar ) {
    $node = $wp_admin_bar->get_node('site-name');
    $node->meta['target'] = '_blank';
    $node->title = 'Home Page';
    $wp_admin_bar->add_node($node);  
    $wp_admin_bar->remove_node('updates');
    $wp_admin_bar->remove_node('comments');
    $wp_admin_bar->remove_node('new-content');
    $wp_admin_bar->remove_node('wp-logo');
    $wp_admin_bar->remove_node('view-site');
}
add_action( 'admin_bar_menu', 'customize_my_wp_admin_bar', 999 );

function wporg_remove_all_dashboard_metaboxes() {
    remove_action('welcome_panel','wp_welcome_panel');
    remove_meta_box('dashboard_primary','dashboard','side');
    remove_meta_box('dashboard_quick_press','dashboard','side');
    remove_meta_box('dashboard_site_health','dashboard','normal');
    remove_meta_box('dashboard_right_now','dashboard','normal');
    remove_meta_box('dashboard_activity','dashboard','normal');
    remove_meta_box('e-dashboard-overview','dashboard','normal'); // WooCommerce  
    remove_meta_box('wpdm_dashboard_widget','dashboard','normal');
   
}
add_action( 'wp_dashboard_setup', 'wporg_remove_all_dashboard_metaboxes' );

function remove_screen_options(){
   return current_user_can( 'manage_options' );
}
add_filter('screen_options_show_screen', 'remove_screen_options');

function oz_remove_help_tabs( $old_help, $screen_id, $screen ){
    $screen->remove_help_tabs();
    return $old_help;
}
add_filter( 'contextual_help', 'oz_remove_help_tabs', 999, 3 );

add_action("admin_head" , function(){
   echo "<style>#dashboard-widgets-wrap .empty-container{display:none}</style>";
});

I only now saw that you tried to install a mu-plugin, but that it was unsuccessful. Why didn't that work? It's very simple to do and the code I shared above is from a mu-plugin I use in almost every site I deliver.
You know how to do that? Create a directory under 'wp-content' called 'mu-plugins', put a file in that directory and name it anything you want, mine is called - surprise, surprise - functions.php

And no, in your own functions.php you do NOT copy content from the theme, you only insert code in order to CHANGE things.

If you don't use plug-ins, you should always remove them, even when the theme keeps requesting to install them. What theme is that by the way? Because most themes will stop nagging when you click on "Dismiss this notice" or something similar. But are you sure those plug-ins are not needed for the booking features?

Since you're not a coder I strongly advice to use a plug-in to hide menu items.

If you got the theme from a resource link here on Babiato, you don't have to check. The only time I'm careful is when some not so well-known member shares a link in a post, but otherwise I trust the resources here.

And why do you wrap everything in a 'function control'? Do you want help or not? If so, don't try to be more clever and just copy the code AS IS!

No, my plug-in is called 'functions.php' but it really doesn't matter what name you give it. By the way, that code I gave is only for the Dashboard clean-up, but let me know if that worked.

Thanks. The reason I was so harsh is: I know this code works. If it doesn't work in your situation and you have added your own code(s) it can be very hard to determine why it doesn't work.

Right, the footer. To remove the footer completely, add this code at the end of the code you already have:

PHP:

add_filter( 'admin_footer_text', '__return_empty_string', 99 );
add_filter( 'update_footer',     '__return_empty_string', 99 );

If you want the footer text replaced with your own, use this code:

PHP:

function remove_footer_admin () {
return 'Your text here, can include HTML';
}
add_filter('admin_footer_text', 'remove_footer_admin', 99);

function remove_footer_update () {
return 'Your text here, can include HTML';
}
add_filter('update_footer', 'remove_footer_update', 99);

For removing Menu Items, I still recommend to use a plug-in. Much easier to maintain, and you don't have to search for pages, links or strings added by your theme and/or plug-ins.

Just use Admin Menu Editor Pro and their addons, trust me.
I was doing this job via code before but it's too hard to keep and check if work new WP versions. So i decided to use a plugin and AME is lightweight and useful.
