You may want to add your own custom functions to your WordPress theme files. The following example is a very simple echo 'hello world!', but if you are using the built in WordPress functions it can be very powerful.
1. First go into your themes folder (wp-content/themes/YOURTHEME/functions.php) and open the functions.php file.
2. Then add your custom function like the example below.
// THE FUNCTION //
function output_hello_world() {
return 'hello world!';
// why use return instead of echo? It allows you to place the output exactly where you need it. Echo will place it at the top of the content //
}
// ADD THE ACTION/FUNCTION TO CALL IN A TEMPLATE FILE //
add_action('call_hello_world', 'output_hello_world');
// ADD THE SHORTCODE/FUNCTION TO CALL IN A POST //
add_shortcode( 'post_hello_world', 'output_hello_world' );3. Now you can call the function in a template file such as wp-content/themes/YOURTHEME/content.php.
<?php
// Call your custom function //
do_action( 'call_hello_world' );
?>Or in a post direct in the CMS with:
// Call your custom function //
[post_hello_world]
