ChronoForms 8.0.52 - Joomla 6.1.0 - Save User action gives Class "JUserHelper" not found

How to fix "Class JUserHelper not found" error in ChronoForms 8 Save User action on Joomla 6.

Overview

The problem is a Joomla 6 compatibility issue where the Save User action uses an outdated class reference.
Edit the file JOOMLA/administrator/components/com_chronoforms8/pages/chronoforms/actions/joomla_user/output.php and change line 52 from JUserHelper::hashPassword to \Joomla\CMS\User\UserHelper::hashPassword. Also ensure form field values use the {data:fieldname} syntax instead of {fieldname}.

Hello,

I am using ChronoForms 8.0.52 on Joomla 6.1.0.

I created a registration/intake form with these fields:{name}{username}{email}{password}

In the Submit event I added the Joomla > Save User action and configured:Account Name: {name}Account Username: {username}Account Password: {password}Account Email: {email}Account Group: RegisteredAccount Status: Activated & Enabled

When I submit the form, I get this error:Class "JUserHelper" not found

Is the Save User action compatible with Joomla 6?Is this related to the free/premium version, or is this a Joomla 6 compatibility issue?

Thank you

Mario

Hi Mario

It may be a Joomla 6 compatibility issue, if you are willing to try a fix:

open this file:

JOOMLA/administrator/components/com_chronoforms8/pages/chronoforms/actions/joomla_user/output.php

Change line 52 from:

$userData['password'] = JUserHelper::hashPassword($userData['password']);

to:

$userData['password'] = \Joomla\CMS\User\UserHelper::hashPassword($userData['password']);

Then let me know how it works for you.

Hi Max,

Thank you, your fix solved the Joomla 6 error.

After changing:

$userData['password'] = JUserHelper::hashPassword($userData['password']);

to:

$userData['password'] = \Joomla\CMS\User\UserHelper::hashPassword($userData['password']);

the “Class JUserHelper not found” error disappeared.

At first the new Joomla user was created with the literal name {name}. I then changed the Save User fields from:

{name}
{username}
{password}
{email}

to:

{data:name}
{data:username}
{data:password}
{data:email}

After that, the Joomla user was created correctly.

So the fix works for me on Joomla 6, and the correct syntax in the Save User action seems to be {data:fieldname}.

Thank you for your help.

Hi Mario

Thanks for the confirmation! 🙂

yes, {data:field_name} is the correct syntax to get a form field value.
