A while back we shared how you can control your WordPress RSS Footer with a use of a famous plugin called RSS Footer by Joost. While the plugin is great, but it is very limited. You can only add text to the footer, and it is always the same text displayed on each post’s footer. What if you want to display different text for each post in your RSS post? What if you want specific posts to have a different title in RSS Feeds? What if you want to display a specific custom field in your RSS Feeds? Well this is why we present you this article which will show you how to add any type of content in your WordPress RSS Feeds. This hack will put you in control of your WordPress RSS Feeds and you can manipulate it in anyway you want.

Note: This hack is not for beginners. Only users who feel comfortable with editing functions.php file and have some knowledge of php should try this. Beginner users should either use the plugin mentioned in the article above, or consult professionals like us to do it for you.

1. Add a Custom Field to your WordPress RSS Footer

In this first example, we will show you how you can use custom field to display specific text/object in your WordPress RSS Feed. This trick will allow you to show different text, advertisement, image, or anything else for each post. First open your functions.php and paste the following codes in the php tags:

An article that details all the uses of PHP would be as long as the New York City phonebook, and about as exciting to read. And while we have tutorials on PHP planned for the future, we thought we’d start everyone off with six fun and easy PHP tricks you can try right now, no matter what your familiarity with the language is.

1. Referrals

This simple example shows the user how they got to your site.

$referer = $_SERVER['HTTP_REFERER'];
echo "You reached this site via " . $referer;

See It In Action: You reached this site via http://www.dzone.com/links/rss/php_tricks_for_beginners.html

Since a user knowing how they got to your site isn’t particularly useful, you need to combine the above script with something, such as a unique page for users who come to your site from a particular location. For example, the script below would send visitors who found your site through Twitter to one page, while all others would be redirected to another. This script, just FYI, needs to go at the very top of the page you’re building.

if (strlen(strstr($_SERVER["HTTP_REFERER"],"twitter"))>0) {
header ('Location: http://' . $_SERVER['HTTP_HOST'] . '/from_twitter.html');
} else {
header ('Location: http://' . $_SERVER['HTTP_HOST'] . '/not_from_twitter.html');
}

Zend Framework 1.10.0 is out and a comment was posted on my blog that lead me to creating this new post. I’m going to focus more on Zend_Paginator and Zend_Rest_Client to access Twitters API since I’ve already created a post on Zend_Cache. Normally, I would use Zend_Service_Twitter to access the twitter service but it still seems to require authentication to retrieve a users timeline where only protected users should require authentication.

Zend_Paginator

Zend_Paginator from the Zend Framework site:

Zend_Paginator is a flexible component for paginating collections of data and presenting that data to users.

Zend_Paginator automatically creates pagination for you by setting up a few parameters and passing it an array of data. What is pagination, if you have ever gone to Google and searched for anything, usually you’ll see something like the following at the bottom of the search results page:

See the numbers and the text links, this is called pagination. So much data exists for the particular search that it wouldn’t make sense to display it all in one page. It would cause large amounts of scrolling down to view, the load time of the page would be affected, so we rather show fewer results and give our users the option of viewing more by clicking on the pagination links.

To demonstrate how to use Zend_Paginator I created a sample Zend Framework 1.10.0 application. This application grabs my last 50 tweets using the Twitter API and displays them 10 at a time using Zend_Paginator. I use Zend_Cache to cache my twitter data so I don’t have to spend time accessing their api every time – I’m sure they would appreciate it.

• Provide a simple text file with a list of addresses, deploy it on GateIn WebDAV drive
• Build with the online IDE a REST API on the cloud (using Groovy and the JSR 311 specification) that reads the content of that file and exposes it as a REST service with a simple click
• Consume that REST service within a Gadget and use the Google maps API to render a map that points to the address from the file
