Question

Is it possible to use JQuery & PHP to create a “like” button that a user could click and it would add +1 to a “number of likes” database (or even text file) and disable the “like” button for that user so that the user could only click it once? I was browsing around and found some information about writing cookies with JQuery:

Perhaps, when a like button is clicked, it could write a cookie to the user’s computer that would prevent them from future clicks? It just basically needs to be that the user could click the like button, it adds a count to some type of database, and it disables the button for the user. Pretty simple I would imagine – there may already be some type of plugin for this, but I haven’t found any. Any ideas?

Thanks!

jquery:

$("button").click(function(){
  $(this).remove();
  $.post('count.php');
});

though the user can just reload the page, so any real validation needs to happen on the php side.
