NO INDIAN PROGRAMERS WANTED For this Jo you need to have knowledge in: - AJAX - PHP - SQL I run a 3.5.1 WordPress site It has a detailed search function to search for items matching a users demands. However the search function causes the SQL process / server to timeout. There must either be a bad code or it needs to be optimized. Also depending on a users search selection, the search form should be updated via Ajax that is hiding or displaying certain search criteria fields depending on the prior selection a user makes.
