Hi there,

A friend of mine asked me how to add some text before and after post content in Wordpress using Plugins.. it’s easy!

Let me tell you how:

function add_test_text($content) {
$content = “Before Content<hr>”.$content;
$content .= “<hr>After Content”;
return $content;
}

add_filter( “the_content”, “add_test_text”,1 );

What we are doing here? let me explain line by line:

function add_test_text($content) {

We are just starting a function here with $content as the first (and only) variable.. Function name is “add_test_text”

$content = “Before Content<hr>”.$content;

What we are doing here is we are assigning “Before Content” as the value of the variable $content.

".$content; this just adds (suffixes) the original $content variable after the string.

$content .= “<hr>After Content”;

If you notice there is a “.” (dot) before “=” (equals to sign), this DOT tells PHP that we want to add something after the variable.. rest is just like above.

return $content;
}

Then we return the post content to wordpress and } closes the function.

add_filter( “the_content”, “add_test_text”,1 );

This is the magic part, what we are doing here is we are telling wordpress to add and apply our function “add_test_text” to post content.

And that is all here is the full code for your “ease”:

<?php
/**
* @package Test Post Content
* @author Salman
* @version 0.1
*/
/*
Plugin Name: Post Content
Plugin URI: http://blog.skdev.net
Author: Salman Mehmood
Description: Shows how to add content before/after post
Version: 0.1
Author URI: http://blog.skdev.net
*/

function add_test_text($content) {
$content=”Before Content<hr>”.$content;
$content.=”<hr>After Content”;
return $content;
}

add_filter( “the_content”, “add_test_text”,1 );

?>

Comments, feedback, critics appreciated
