So, using this shortcode function, you can define a handler function that parse the shortcode and then return the output.
First you need to register a shortcode using add_shortcode() method.
For e.g.
add_shortcode( <shortcode_name>, <handler_function>);
<shortcode_name> (required, string) : This is a string which to be searched in the post.
<handler_function> (required, callable) : This is a hook to run when a shortcode is found.
Make the shortcode in your plugin file or in function.php file so that this can be usable for all space.
<?php
/*
Plugin Name: Data Fetch
Plugin URI: http://www.namasteui.com
Description: WordPress collection data from database using a shortcode
Version: 1.0
Author: Namaste UI
Author URI: www.namasteui.com
*/
if ( !defined( 'WP_FD_ABSPATH' ) )
define( 'WP_FD_ABSPATH', plugin_dir_path( __FILE__ ) );
function wp_data_fetch(){
echo "Your functionalities here.";
}
add_shortcode('data_fetch', 'wp_data_fetch');
?>
(a) Create a function first called “function wp_data_fetch()”.
(b) Then using wordpress handler, “add_shortcode” define your function in it and in your admin post or Page use “data_fetch” as short code [data_fetch].
(c) As a result the value which is written will be showed on that post or page.
