How to execute shortcodes inside custom fields

By default, WordPress do not allows shortcodes to be executed inside custom fields. If for some reason you need to be able to execute a shortcode inside a specific custom field, here is an easy way to do it.

Just put this code into whatever page you are displaying the results of the shortcode, and change the your_custom_field_here to the name of your custom field.

<?php echo apply_filters('the_content', get_post_meta($post->ID, 'your_custom_field_here', true)); ?>
