This feature is part of the Visforms Subscription and not available in the free Visforms version..
Sometimes you want to limit how often a form can be submitted in total. For example, if you manage the registration of an event with limited participants. The useful tiny plugin enables you to achieve exactly that with a Visforms form.
What is a plugin and how does it work?
Joomla! supports the use of so called plugins. Plugins are small applications, which can hook into the code at various places and perform specific tasks. For example email cloaking is a typical plugin task as well as switching languages on multi language websites.
How does the plugin "Limit Maximum Submissions" work?
Using stored user inputs, the plugin calculates the amount of submissions already made for a form. If the this number equals the limit of submissions permitted for the form, which you can set as a plugin option, the plugin will prevent the user from submitting the form and display an error message.
