I stumbled across this RSS feed reader on w3schools.com.
http://www.w3schools.com/php/php_ajax_rss_reader.asp

It works great and I am able to add RSS-feeds without a problem. My question is, how do I add social media buttons such as Facebook Like or a Twitter button? For each story or news article, I would like my users to be able to share via Facebook or reTweet the story. How do I do this with w3schools code?

This is just a basic example.

In the example PHP file on w3schools, to add a facebook "LIKE" link, you can change this part:

//output elements from "<channel>"
echo("<p><a href='" . $channel_link
  . "'>" . $channel_title . "</a>");
echo("<br />");
echo($channel_desc . "</p>");

Open in new window


to this:

//output elements from "<channel>"
echo("<p><a href='" . $channel_link . "'>" . $channel_title . "</a>");
echo("<br /><a href='http://www.facebook.com/plugins/like.php?app_id=159397647477718&href=" . $channel_link ."' target='_blank'>Facebook Like</a><br />");
echo($channel_desc . "</p>");

Open in new window


As you can see, I added a new anchor tag element into the code that uses the $channel_link and made it part of the facebook url.
You can also make a facebook button and use that instead:

The same concept applies to twitter or any other social site. Use their public API links in your code.

Oh and you can do the same modification to the other part of the php file. This way you can have "LIKE" links for each item of the rss feed.

Change this:

  echo ("<p><a href='" . $item_link
  . "'>" . $item_title . "</a>");
  echo ("<br />");
  echo ($item_desc . "</p>");

Open in new window


to this:

  echo ("<p><a href='" . $item_link
  . "'>" . $item_title . "</a>");
  echo("<br /><a href='http://www.facebook.com/plugins/like.php?app_id=159397647477718&href=" . $item_link ."' target='_blank'>Facebook Like</a><br />");
  echo ($item_desc . "</p>");

What about a re-tweet button?

You can learn how to make a twitter link here:
https://dev.twitter.com/docs/tweet-button


Adding a tweet link is no problem.
I added it next to the facebook link.

//output elements from "<channel>"
echo("<p><a href='" . $channel_link . "'>" . $channel_title . "</a>");
echo("<br /><a href='http://www.facebook.com/plugins/like.php?app_id=159397647477718&href=" . $channel_link ."' target='_blank'>Facebook Like</a><br /><a href='http://twitter.com/share?url=" . $channel_link ."' target='_blank'>Tweet</a><br />");
echo($channel_desc . "</p>");

Open in new window


Also for the second part:

  echo ("<p><a href='" . $item_link
  . "'>" . $item_title . "</a>");
  echo("<br /><a href='http://www.facebook.com/plugins/like.php?app_id=159397647477718&href=" . $item_link ."' target='_blank'>Facebook Like</a><br /><a href='http://twitter.com/share?url=" . $item_link ."' target='_blank'>Tweet</a><br />");
  echo ($item_desc . "</p>");
