Question

I’m building a plugin which will pull custom meta post automatically.

For example if I have a post with content

"A post content"

when display content in the theme used the_content() tag, I want to display as :

A post content <br> <div id="custom-data">Some custom data</div>

In that way, I can build a plugin to pull custom meta post automatically and re-style the custom data.

Anyone know it? Thanks!

You can use add_filter() to add text to the content. Here’s an example:

function functionname($text){
     $text .= 'Some extra text, added below the content';
     return $text;
}
add_filter('the_content', 'functionname');

There are many filters you can hook on, here’s a list: http://codex.wordpress.org/Plugin_API/Filter_Reference
