php - How can I filter / query wordpress posts using ajax, live? -

i have wordpress website, has number of posts, , number of filters (with ui set up) in theme custom build.

want want change query posts tags live using ajax, user can posts want using filters:

• popularity (custom taxonomy)
• time posted
• tags
• colour (custom),
• keyword (using search bar)
• category

i have found php script similar thing, not live, , not give ability update live; script here query.

<?php if( !empty($_get['order']) ) $order=$_get['order']; else $order='desc'; // default  if( !empty($_get['orderby']) ) $orderby=$_get['orderby']; else $orderby = 'date'; // default if( !empty($_get['cat']) ) $orderby=$_get['cat']; else $category = ''; // default   query_posts('orderby='.$orderby.'&order='.$order.'&meta_key='.'_post_like_count'.'&cat='.$category)             ?> 

the script changing (that changes queries) here, anchor adds url onto the search term.

<a href="?order=desc&orderby=meta_value_num">popular</a> 

i have done querying few values, before whole filtering system working, , acknowledge may have re done, know ajax cannot change url live user, , has use requests.

does know how approach task in way, , can give me guidance on how achieve it?

i open plugins, yet prefer integrating locally custom theme build.
