In this tutorial I am showing you how you will restrict the submission action of your Fluent Form. Assume that you are running a restaurant website and selling 100 meals per day. You create a reserve/order form for meal. In the form there have a quantity field for meals which will manage the stock. So form will disappear or user can’t submit the order form, when total meal value will reach to 100.
You can easily do this with WP Fluent Forms plugin. There have a filter fluentform_is_form_renderable. Using this filter you can hide the form on website. You will add the following PHP code into the theme’s functions.php file or custom plugin.
