WP::register_globals() WordPress Method

The register_globals() function in WordPress allows you to register custom global variables for use in your theme or plugin. This function takes two arguments: the name of the variable to register, and the value to assign to it. For example, if you wanted to create a global variable named $foo with the value "bar", you would use the following code: register_globals( 'foo', 'bar' ); You can then access the $foo variable anywhere in your theme or plugin code by using the global keyword, like so: global $foo; echo $foo; // outputs "bar" Keep in mind that the register_globals() function should be used sparingly, as it can potentially create security risks if not used carefully.

		$GLOBALS['request']      = $wp_query->request;

		if ( $wp_query->is_single() || $wp_query->is_page() ) {

			$GLOBALS['single'] = 1;
		}

		if ( $wp_query->is_author() ) {
