There are several ways of protecting web forms from spam; one of these is the HoneyPot input - that's a form input that isn't visible to a human user but will probably be seen and completed by a spam bot. So if there is a value in the input the form is probably spam. This FAQ tells you how to set up a HoneyPot input.

I use GoDaddy and my emails aren't sending
Go Daddy has a setting in it's email service that, by default, prevents emails being sent to addresses on the site domain for example: an email from some_address@mydomain.com can't be sent to another_address@mydomain.com
The solution depends on the server configuration, the GoDaddy help line should be able to fix it for you. Here is one example as a guide:
In cPanel go to Email -> MX Entry; under Email Routing, select “Remote Mail Exchanger” and click Change; then verify that there are “no MX records”.
Thanks to user Dalana for this information.

How can I upgrade to a new release?
For any of the current CFv4, CFv5, CCv4 or CCv5 releases you can upgrade by installing the new version over the older one. If you have an older version of CFv3 you may need to uninstall and re-install, please check the notes on the download page for your previous version. To upgrade the CF plug-ins and module you need to uninstall and re-install.
It should not be necessary, but for security it is worth taking a backup of your forms and any ChronoForms related database tables before upgrading.
Note: there is no automatic upgrade from CFv3 to CFv4 or from CFv4 to CFv5 - see the upgrade FAQ for more information.

How can I create an 'rtl' form?
ChronoForms supports RTL - right-to-left - language layouts with a setting on the Styles tab of the Form Editor. This changes the CSS to move the labels to the right and make the other changes needed.
For a Multi-Language site where you need to switch between rtl and ltr languages you can add this code in a Custom Code action in the form On Load event before the HTML (render form) action.
<?php
$jlang = JFactory::getLanguage();
$dir = $jlang->get('rtl');
if ( $dir == 1 ) {
$form->params->set('rtl_support', 1);
}
?>
This checks the rtl setting of the current language and switches the form rtl setting to match.

My multi-select dropdown doesn't republish
To make a multi-select drop-down work so it reselects items when editing a record you need to do the following:
↧
How can I edit the record for an image?
When a form includes an image ChronoForms will save the image name in a database table. This allows the image to be recovered and displayed as needed but it can be difficult to edit the record if changes are needed. When you re-display the record in an edit form the file upload input is not filled in; and if the user submits the form with the file upload empty the existing image name can be over-written with a empty name.
