Shortcodes means you can call some function or methods using short keys or codes.
Shortcodes essentially get replaced by some other content you define. Let’s take a look at the basics through an example.

Coding this is actually very simple. We’ll need to use the add_shortcode() function to tell WordPress about our shortcode, and then create our function to handle the output:

add_shortcode( ‘firstcode’, ‘code_output’ );
function code_output() {
return ‘ikodes demo text’;
