add rewrite rules for custom post types

See that sivel helped you:

add_filter('generate_rewrite_rules', 'customposttype_rewrites');
function customposttype_rewrites($wp_rewrite) {
	$newrules = array();
	$newrules['mycustomposttype/?$'] = 'index.php?post_type=mycustomposttype';
	$wp_rewrite->rules = $newrules + $wp_rewrite->rules;
}

Ok, it’s a first idea ! Thanks.
My full problem is here.

Sivel’s revised code

https://wordpress.pastebin.com/TgmWTZVU

Hi – I’m trying to play around with Sivel’s code above but I’m struggling to achieve what I want. I have a custom post type named ‘work’, and a hierarchal taxonomy named ‘clients’ which is exclusive to the ‘work’ post panel. How could I achieve it so that visiting “domain.com/work/clients/client_x” would pull all the posts with that ‘client_x’ taxonomy? It’s the equivalent of visiting “domain.com/index.php?clients=client_x”, but I can’t get it to work. Here’s the code I’m trying:

add_action('generate_rewrite_rules', 'work_list');
function work_list($wp_rewrite) {
    $newrules = array();
    $newrules['work/?$'] = 'index.php?post_type=work';
    $newrules['work/page/?([0-9]{1,})/?$'] = 'index.php?post_type=work&paged=$matches[1]';
    $newrules['work/clients/?([0-9]{1,})/?$'] = 'index.php?clients=?$])';
    $wp_rewrite->rules = $newrules + $wp_rewrite->rules;
}

Thanks!

This is what I came up to.
But not all is working.
Could anyone help ?

function yclads_rewrite_rules($wp_rewrite) {

$newrules = array();

//HOME
$newrules[‘(classifieds)’] = ‘index.php?post_type=yclad’;
//HOME + TIME
$newrules[‘classifieds/(\d*)’] = ‘index.php?post_type=yclad&year=’ . $wp_rewrite->preg_index(1);
$newrules[‘classifieds/(\d*)/(\d*)’] = ‘index.php?post_type=yclad&year=’ . $wp_rewrite->preg_index(1) . ‘&month=’ .$wp_rewrite->preg_index(2);
$newrules[‘classifieds/(\d*)/(\d*)/(\d*)’] = ‘index.php?post_type=yclad&year=’ . $wp_rewrite->preg_index(1) . ‘&month=’ .$wp_rewrite->preg_index(2) . ‘&day=’ .$wp_rewrite->preg_index(3);

##ALL THOSE ABOVE DO NOT WORK

//”PLACE AD”
//TO FIX
$newrules[‘classifieds/place-ad$’] = ‘index.php?post_type=yclad&place-ad’;

//SINGLE ACTION
$newrules[‘classifieds/action/(\w*)$’] = ‘index.php?post_type=yclad&yclad_action=’ . $wp_rewrite->preg_index(1);
//SINGLE ACTION + SINGLE CAT
//here the URL should be the breadcrumb to the child category and we should care only about the last category instance
$newrules[‘classifieds/action/(\w*)/category/(\w*)$’] = ‘index.php?post_type=yclad&yclad_action=’ . $wp_rewrite->preg_index(1).’&yclad_category=’ . $wp_rewrite->preg_index(2);
//SINGLE ACTIONS + SINGLE TAG
$newrules[‘classifieds/action/(\w*)/tag/(\w*)$’] = ‘index.php?post_type=yclad&yclad_action=’ . $wp_rewrite->preg_index(1).’&=yclad_tag’ . $wp_rewrite->preg_index(2);

//SINGLE CAT
$newrules[‘classifieds/category/(\w*)$’] = ‘index.php?post_type=yclad&=yclad_category’ . $wp_rewrite->preg_index(1);

##++ what about combining this with author or time parameters ?
##++ have I to register those tags to allow custom permalinks ?how ?

$wp_rewrite->rules = $newrules + $wp_rewrite->rules;

}
add_action(‘generate_rewrite_rules’, ‘yclads_rewrite_rules’);
