title: dynamic sql query using jquery + php
body: <p>Just wondering if anyone can point me in the directuon of some tutorial/s that
  Delve into sql queries/insertions/deletions (is that a word?) using jquery and/or php.</p>
  
  <p>What I was specifically wanting to do was have a button that added an entry to a table
  And then the button would change or dissappear or become greyed out.</p>
  
  <p>Any links that might set me on the right track would be awesome!</p>
  
  <p>Thank you in advance!</p>
