Nastavení úrovně přístupu v pluginech

Almost every plugin needs to have at least one page in the admin area to let users customize how the plugin is used. In order to do this, you need to add your own administration menu items. There are a bunch of WordPress functions which let you do this:


// add top level menu
add_menu_page(page_title, menu_title, capability, handle, [function], [icon_url]);
 
// add sub-menu pages
add_submenu_page(parent, page_title, menu_title, capability, file/handle, [function]);
 
// add Options sub-menu
add_options_page(page_title, menu_title, capability, handle, [function]);
 
// add Management sub-menu
add_management_page(page_title, menu_title, capability, handle, [function]);
 
// add Pages sub-menu
add_pages_page( page_title, menu_title, capability, handle, [function]);
 
// add Posts sub-menu
add_posts_page( page_title, menu_title, capability, handle, [function]);
 
// add Appearances sub-menu
add_theme_page( page_title, menu_title, capability, handle, [function]);

Zobrazení obsahu pouze přihlášeným uživatelům

Do souboru functions.php (Vzhled > Upravit soubory) stačí přidat následující:


add_shortcode( 'member', 'member_check_shortcode' );

function member_check_shortcode( $atts, $content = null ) {
	 if ( is_user_logged_in() && !is_null( $content ) && !is_feed() )
		return $content;
	return '';
}

Pak už stačí kdekoli v příspěvku „obalit“ text určený pouze registrovaným uživatelům tagem [member]:


[member]
Toto se zobrazí pouze přihlášeným uživatelům
[/member]

Je-li potřeba to nastavit už v šabloně vzhledu, je třeba použít


<?php
if (is_user_logged_in()):
echo "Toto se zobrazí pouze přihlášeným uživatelům";
endif;
?>

The Capability Manager plugin provides a simple way to manage role capabilities. Using it, you will be able to change the capabilities of any role, add new roles, copy existing roles into new ones, and add new capabilities to existing roles. You can also delegate capabilities management to other users. In this case, some restrictions apply to this users, as them can only set/unset the capabilities they have. With the Backup/Restore tool, you can save your Roles and Capabilities before making changes and revert them if something goes wrong.
