Parsing variables in WordPress permalinks WordPress

Denzel Chia comments:

I should have read http://wpquestions.com/question/show/id/618
and not waste my time here!

Since you "had" the answer, "I recommend you to read this question and just modify his code so it will be easy for you."

Thanks for your reply.

But when I add any variable to the URL the wordpress is automatically redirecting to the original permalink.

Dharshan Venkadesan comments:

Thanks for all answers.
But I fixed it myself by using this coding in rewrite_rules.php


$rr_rewrite_rules = array(


'([0-9]+)/(.+?)/([^/]+)/test.html(/[0-9]+)?/?$' => 'index.php?mystring=play&p=$matches[1]&category_name=$matches[2]&name=$matches[3]&page=$matches[4]'
);
$wp_rewrite->rules = $rr_rewrite_rules + $wp_rewrite->rules;

Anyways I will choose you as the winner because of your time spent and effort :-)

This is the final one:
<?php
// code by WJM ( 776a6d # gmail.com )
$flush_rules = FALSE;
//Comment this line below to set $flush_rules to false, after the first time of loading a page to improve performance
//$flush_rules = TRUE;

register_activation_hook ( __FILE__, 'rr_flush_rewrite_rules' );
add_action( 'generate_rewrite_rules', 'rr_add_rewrite_rules');
add_filter( 'query_vars', 'rr_add_rewrite_query_vars' );

function rr_add_rewrite_rules($wp_rewrite) {

// FOR PERMALINK STRUCTURE: /%post_id%-%postname%/
$rr_rewrite_rules = array(
'([0-9]+)/(.+?)/([^/]+)/play.html(/[0-9]+)?/?$' => 'index.php?mystring=play&p=$matches[1]&category_name=$matches[2]&name=$matches[3]',
'([0-9]+)/(.+?)/([^/]+)/view.html(/[0-9]+)?/?$' => 'index.php?mystring=view&p=$matches[1]&category_name=$matches[2]&name=$matches[3]'
);
$wp_rewrite->rules = $rr_rewrite_rules + $wp_rewrite->rules;
}

function rr_add_rewrite_query_vars($public_query_vars) {
$new_vars = array(
'mystring',
);
return array_merge($public_query_vars, $new_vars);
}

add_action( 'template_redirect', 'rr_disable_canonical', 9);
function rr_disable_canonical() {
if ( get_query_var( 'mystring' ) )
remove_action('template_redirect', 'redirect_canonical');
return;
}

function rr_flush_rewrite_rules() {
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
if ( $flush_rules == TRUE )
add_action( 'init', 'rr_flush_rewrite_rules');
