I added the code in the following file successfully :
wp-content/plugins/gwlimitchoices/gwlimitchoices.php
Can the same be added to dropdown?
How could this be modified to only add the " x spots left" message to certain types of fields or by certain fields only using their field id?
For anyone else that might want to restrict this to just a certain field on a certain form, here is how I achieved that:
You will need to modify the $form['id'] and $field->id that you want to target within the condition of the if-statement.
add_filter( 'gplc_remove_choices', '__return_false' );
add_filter( 'gplc_pre_render_choice', 'mw_add_how_many_left_message_to_limited_fields', 10, 5 );
function mw_add_how_many_left_message_to_limited_fields( $choice, $exceeded_limit, $field, $form, $count ) {
$limit = rgar( $choice, 'limit' );
$how_many_left = max( $limit - $count, 0 );
$message = "($how_many_left Spots Left)"; // Modify Message Displayed for # of "Spots Left"
if ( $field->get_input_type() == 'select' && $field->id == '17' && $form['id'] == '5') {
$choice['text'] = $choice['text'] . " $message";
}
return $choice;
}
Thanks for sharing, @mike-weiner. Another option is to include the target form and field IDs in the filter name like so:
gplc_pre_render_choice_5_17
@spivurno Thanks for the quick response! That is much easier!

Hi David, should this code be added to the Wordpress theme's function.php file or Child theme function.php? I have tried both and receive a parse error. Thank you for your help.
