title: mysql stuff when click on link then go to link
body: <p>I have a phpBB forum, some posts contains Links... I want to count how many times the link on the post has been visited...</p>
  
  <p>I think that catching the "click" on the link, make php and mysql stuff and, then after all, go to the external link is the best way ... but I dont know how to do that.</p>
  
  <p>Its possible to interrupt the link click, modify some things and then load de link as always? (maybe using ajax or jquery)</p>
  
  <p>A link example could be:</p>
  
  <p>www.google.com</p>
  
  <p>The mysql table called phpbb_likes contains:</p>
  
  <pre><code>Like_id
  Post_id
  User_id
  Like_time
  </code></pre>
  
  <p>I know how to add a new like using something like this:</p>
  
  <pre><code>Insert INTO phpbb_likes ("Post_id","User_id","Like_time") VALUES ("2355","45","1343546456");
  </code></pre>
  
  <p>But the problem is interrupting the link redirecting to make that sql query</p>
  
  <p>Any Idea?
  thanks</p>
