Tag: plugin

This is a basic example of how to create your own WordPress plugin.

Create a file called my-plugin.php and save it to a new folder /wp-content/plugins/my-plugin:

<?php
/**
 * @package Show all the tags in a web site
 * @version 0.1
 */
/*
Plugin Name: Show all the tags used in a web site
Plugin URI: http://cagewebdev.com/
Description: Show all the tags, used in a web site
Author: Rolf van Gelder
Version: 0.1
Author URI: http://cagewebdev.com
*/
?>
<?php
function rvg_show_all_tags()
{   $arr = wp_tag_cloud('format=array&smallest=10&largest=10&number=0');
    $output  = '<h3>All Tags ('.count($arr).')</h3>';
    $output .= '<div style="border: solid 1px #ccc; padding:10px;">';
    for($i=0; $i<count($arr); $i++)
    {   if($i) $output .= ', ';
        $output .= $arr[$i];
    }
    $output .= '</div><br />';
    return $output;
}
add_shortcode('rvg-show-all-tags', 'rvg_show_all_tags');
?>

Note: don’t use the ‘echo’ command but store the output in a variable and return that variable!
