Sorry I read your question wrong. You probably want to use WP_Rewrite and do something like:
add_filter( 'rewrite_rules_array','my_insert_rewrite_rules' );
add_filter( 'query_vars','my_insert_query_vars' );
add_action( 'wp_loaded','my_flush_rules' );
// flush_rules() if our rules are not yet included
function my_flush_rules(){
$rules = get_option( 'rewrite_rules' );
if ( ! isset( $rules['(argument_1=test&argument_2=test2)$'] ) ) {
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
}
// Adding a new rule
function my_insert_rewrite_rules( $rules )
{
$newrules = array();
$newrules['(argument_1=test&argument_2=test2)$'] = 'index.php?argument_1=$matches[1]&argument_2=$matches[2]';
return $newrules + $rules;
}
// Adding the id var so that WP recognizes it
function my_insert_query_vars( $vars )
{
array_push($vars, 'id');
return $vars;
}
this is untested and mostly stright from the docs but should get you on the right track.
