Beautify URL

Hello,

If someone else also needs it.

Add the code:

add_action('init', '_ymm_add_url_parameters');
add_filter('query_vars', '_ymm_add_query_vars');
add_action('parse_query', '_ymm_parse_query');

function _ymm_add_url_parameters(){ 
   // To make it work with SEO URL like:
   // https://website.com/vehicle/BMW/X3/2008/
   // instead of:
   // https://website.com/?s=&ymm_search=1&post_type=product&_make=BMW&_model=X3&_year=2008
   // 
   // Don't forget to refresh the wordpress permalink settings after changing the rewrite rules in:
   // WordPress dashboard -> Settings -> Permalink 
   //   click the "Save changes" button at the bottom of the page
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]', 'top');
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/page/([0-9]{1,})/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]&paged=$matches[2]', 'top');   
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/([A-Za-z0-9-\s]+)/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]&_model=$matches[2]', 'top');
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/([A-Za-z0-9-\s]+)/page/([0-9]{1,})/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]&_model=$matches[2]&paged=$matches[3]', 'top');
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/([A-Za-z0-9-\s]+)/([0-9]+)/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]&_model=$matches[2]&_year=$matches[3]', 'top');
   add_rewrite_rule('^vehicle/([A-Za-z0-9-\s]+)/([A-Za-z0-9-\s]+)/([0-9]+)/page/([0-9]{1,})/?$', 'index.php?s=&ymm_search=1&post_type=product&_make=$matches[1]&_model=$matches[2]&_year=$matches[3]&paged=$matches[4]', 'top');   
}

function _ymm_add_query_vars($aVars) {
  $aVars[] = "ymm_search";
  $aVars[] = "_make";
  $aVars[] = "_model";
  $aVars[] = "_year";                 
  return $aVars;
}

function _ymm_parse_query($where) {  
  $ymm_make = get_query_var('_make');
  if ($ymm_make){
   $_GET['ymm_search'] = get_query_var('ymm_search');
   $_GET['_make'] = get_query_var('_make');
   $_GET['_model'] = get_query_var('_model');
   $_GET['_year'] = get_query_var('_year');
   $_GET['s'] = get_query_var('s');	 		 	 		 		 
  }    
}

to the end the file:
wp-content/plugins/ymm-search/ymm-search.php

Replace the line:

  window.location.href = url + '?' + $.param(params);

with:

if (!categoryUrl){        
        var pNames = this.levelParameterNames;
        var l = pNames.length;
        url = url.replace(/\/+$/, '');
        url += '/vehicle/';
        for (var i=0;i<l;i++) {
          if (values[pNames[i]] != undefined){
            url += values[pNames[i]] + '/';  
          } 
        }
        window.location.href = url; // seo url www.website.com/vehicle/BMW/X5/2000/   
      } else {           
        window.location.href = url + '?' + $.param(params);
      }

in the file:
wp-content/plugins/ymm-search/view/frontend/web/main.js

After applying the modification refresh the wordpress permalink settings in:
Wordpress dashboard -> Settings -> Permalink
click the “Save changes” button at the bottom of the page.

And refresh your browser cache to make it load the updated version of the .js file.
