Get Custom Field Values [get_custom_field_values] Shortcode
The get-custom-field-values shortcode enables you to fetch and display custom field values from your posts. It’s versatile, allowing you to specify the post ID, field, and output format. This PHP code defines the shortcode function. It first checks if the author has permission to use shortcodes. It then sets default values and overwrites them with any provided in the shortcode. It determines the type of post data to retrieve (current, random, or specific) and formats the output accordingly. If ‘id’ or ‘class’ attributes are defined, the output is wrapped in a span tag.
