<?php
// \'current_screen\' action fires after the current screen has been set
add_action( \'current_screen\', \'my_check_current_screen\' );

// $current_screen is WP_Screen object passed by the \'current_screen\' action
function my_check_current_screen( $current_screen ) {

    // compare current screen ID to the string of your choice
    if( \'options-permalink\' === $current_screen->id ) {
        echo \'I am on the "Permalink Settings" screen\';
    }
}

add_action( \'current_screen\', \'my_print_current_screen_object\' );

function my_print_current_screen_object( $current_screen ) {

    echo \'<pre>\';
    print_r( $current_screen );
    echo \'</pre>\';

}

在函数中尝试以下几行。

global $pagenow;
echo $pagenow; // This should give you current page of admin page

我不知道你到底想做什么。但基本上，您可以使用：

is_page( \'contact\' ) // To see if this page is the page contact

is_singular( \'post\' ) // To see if this is a spefic post type

get_permalink() // To get the permalink of a post inside the loop

global $pagenow // To get the page you are now
