It is a very strong capability to be able to post dynamic content in your blog. You can use this to integrate contents from other websites, fetch data from your database etc. It enables whole plethora of functionalities to your blog posting to make it more lively.

A plugin developed by Mark allows you to do just that. Follow the link to download the plugin.

Here's an example of dynamic code.

This is your IP address - echo getenv('REMOTE_ADDR');.

Your national flag
Country flag

You are from include 'http://www.hostip.info/api/get.html' . '?ip=' . getenv('REMOTE_ADDR') . '&position=true';

Is this information correct?

Update: This page may not work correctly because I installed a caching plugin to speed up site access and reduce load on my servers. The plugin has ways to execute dynamic code, however that has not been implemented yet on this page.
