Yes you can, some thing like this.
add_filter( 'wccpf/before/fields/rendering', 'render_fields_by_tag' );
function render_fields_by_tag( $field ) {
global $post;
$html = "";
if( has_tag( "Your Tag", $post ) ) {
$html = '<input type="text" name="'. esc_attr( $field["name"] ) .'" value="'. esc_attr( $field["default_value"] ) .'" placeholder="'. esc_attr( $field["placeholder"] ) .'" maxlength="'. esc_attr( $field["maxlength"] ) .'" />';'
}
return $html;
}
Thanks,
It would be good to have this option (rule) available in the plugin settings.
Bit late but Rules By Tag option has been included with V1.2.5
