I got this working on my bar by using the following. Hope it helps. Basically you have to add two actions, one for a field of first name, the second for the last name. Feel free to see it on my wife’s food blog at http://www.grabsomejoy.com
add_action( ‘mctb_before_email_field’, function() {
echo ‘<input type=”text” name=”FNAME” placeholder=”First Name” required>’;
echo ‘<input type=”text” name=”LNAME” placeholder=”Last Name” required>’;
});
add_filter( ‘mctb_merge_vars’, function( $vars ) {
$vars[‘FNAME’] = ( isset( $_POST[‘FNAME’] ) ) ? sanitize_text_field( $_POST[‘FNAME’] ) : ”;
return $vars;
});
add_filter( ‘mctb_merge_vars’, function( $vars ) {
$vars[‘LNAME’] = ( isset( $_POST[‘LNAME’] ) ) ? sanitize_text_field( $_POST[‘LNAME’] ) : ”;
return $vars;
});
