| /** | ||
| * Implements bw_contact_field shortcode. | ||
| * | ||
| * For use in the bw_contact_form shortcode / block. | ||
| * | ||
| * The idea of this shortcode is to be able to register the fields that will appear in the contact form. | ||
| * By default these will be 'name,email,subject,message', in that order. | ||
| * When the bw_contact_form shortcode contains embedded content then the fields can be overridden. | ||
| * Unless the `name` attribute is set, each bw_contact_field shortcode will register a field with a full name | ||
| * consisting of a prefix ( default `oiku_contact-n` ) and the `name` generated from the `label`. | ||
| * The bw_contact_form shortcode will use these fields to construct the form. | ||
| * | ||
| * Examples: | ||
| * [bw_contact_form][bw_contact_field Email][/bw_contact_form] | ||
| * [bw_contact_form][bw_contact_field Name][bw_contact_field Telephone][/bw_contact_form] | ||
| * | ||
| * Note: The Message ( textarea ) field is automatically added. This is a required field. | ||
| * @param $atts | ||
| * @param $content | ||
| * @param $tag | ||
| * @return string | ||
