title: Update records without refresh
body: <p>Apologies if this has been asked before but I'm not sure what to search for exactly so I thought it would be better to explain it. </p>
  
  <p>I am using php to get records from a mysql table and present them. However I have added couple of dropdowns and search boxes to filter out the results and I would like to do it without refreshing the page. Can anyone point me to a tutorial or something like that? I guess I should use jQuery but as I said I don't know what to look for exactly.</p>
  
  <p>Thank you!</p>
