There's a few things you have to pay attention to :
You have to flush the rewrite rules only on plugin activation/deactivation, not on init, in order to prevent performance issues.
The rewrite_rule first parameter must be a regex.
The init hook is an action, not a filter.
Below plugin code does work :
<?php
/*
Plugin Name: Rewrite test
*/
function custom_rewrite_basic() {
add_rewrite_rule('^testurl?', 'wp-content/plugins/my-plugin/testurl.php', 'top');
}
register_deactivation_hook( __FILE__, 'flush_rewrite_rules' );
register_activation_hook( __FILE__, 'myplugin_flush_rewrites' );
function myplugin_flush_rewrites() {
custom_rewrite_basic();
flush_rewrite_rules();
}
Hope this will help.
