Introduction

This feature is part of the Visforms Subscription and not available in the free Visforms version..

Impatient users or mails, stuck in spam folders, may mislead users to try to fill in and submit a form twice. The plugin "Delay Double Registration" enables you to set a time span during which a user will not be able to submit the form twice an thus will prevent double registration and doublicate record sets.

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 "Delay Double Registration work"?

The plugin uses the stored user inputs to check, if a user has already submitted the form. Therefore the plugin can only work as expected if you have enabled the "Save result" option for this form. If a user has already submitted the form, the plugin checks further on, that the time span between this submission and now is longer than the delay time span defined in the plugin settings. If not it prevents the user from submitting the form again.

The plugin uses the IP address, to identify who is "a user". Therefore there is no 100 percent security, that a user cannot submit a form twice even within the delay time span, if they really want to. Nevertheless, the plugin provides an easy and effective protection from unintentional double registration even if the form is submitted by a user who is not logged in.
