Problem with context in multisite - getting main site data in every blog (get_pages())

Question

I'm working on a multisite, everything is configured and works fine from dashboard. Now I'm trying to write a plugin with a PHP file that displays the list of pages created in a site - to be displayed to the admin of the site who logs in.

Here is the code (simplified)

<?php
require('../../../wp-load.php');
?>
(some HTML)
<?php    
    $pages = get_pages();                                  

    foreach ( $pages as $page ) {
        echo $page->post_title . '<br>'
?>

My plugin PHP file uses login_redirect filter to redirect user after login to that PHP file where I am trying to display the list of pages the user created:

function my_login_redirect( $redirect_to, $request ) { 
    return '/wp-content/plugins/my-admin-plugin/my-admin-view-all-pages.php'; 
}

THE PROBLEM - no matter which site I'm in, I get the list of pages created in the "main" site. How do I pass the context of the existing site to the functions?

Answer 1

The way you are doing this is not correct.

Two possibilities:

1) Create a Dashboard Widget to display the information

• For the Network Dashboard, but illustrates well: How to Display Network Post Count?
• Minimal widget:

add_action('wp_dashboard_setup', 'wpse_60096_dashboard_widget');

function wpse_60096_dashboard_widget() {
    if( current_user_can( 'activate_plugins' ) )
        wp_add_dashboard_widget( 
            'wpse_60096', 
            'Site Pages', 
            'wpse_60096_add_widget_content'
        );
}

function wpse_60096_add_widget_content() {
    $pages = get_pages();                                  
    foreach ( $pages as $page ) 
        echo $page->post_title . '<br>'; 
}

2) Register an invisible submenu page

• Plugin - create a page without it appearing in the side menu
• Redirect the login to that page: How to create and link to administration page for a plugin?
