html - Price low - high / high - low filter PHP/Mysql -

i looking way create filter (select dropdown menu) selects products based on price.

i know possible query this:

select * products order price asc  select * products order price desc  

but problem not want pass gets url select query.

is possible execute jquery command populate results?

this select:

<select name="filter"> <option value="lowhigh">price: low - high</option> <option value="highlow">price: high - low</option> </select> 

thanks in advance.

i see no reason not pass sort of query through get. still remains impossible inject/xss, there 2 options, without ability of user add his/her own information. sites ebay, amazon , etc. do. define variable other responders suggested. highly secure , recommend it. if wish use save user refreshing, use ajax - implemented in jquery default.

from html of:

<select id="filter"> <option value="lowhigh">price: low - high</option> <option value="highlow">price: high - low</option> </select> 

use jquery of:

$("#filter").change(function() {     //whatever ajax wish use });
