JX is the integration is based on Joomla 1.5.15 and X-Cart 4.3.1, and include the following: 1. All registered users of Joomla (including admin) should be registered users of X-Cart and vice versa. 2. If a user logs into Joomla and then opens X-Cart, he/she should also be logged in X-Cart too and vice versa. 3. Admin of Joomla site can create custom fields in user profiles using CB - community builder (famous free extension of joomla). All these user profile custom fields in Joomla should appear for X-Cart registered users also. As a result, the fields in the user profiles in Joomla and X-Cart should be the same. Joomla is the primary system for adding custom fields to user profile. 4. If a customer clicks "Register" from X-Cart store, he/she should be redirected to the Joomla registration page. After filling out all the required information, the customer should be redirected back to the page, from which he/she has clicked "Register". 5. For modifying profiles in X-Cart admin should be redirected to the Joomla "Modify profile" page in Joomla. We should add "Back to X-Cart admin area" to the user profile page in Joomla, so that after admin opens the profile, he/she will always be able to go back. 6. In joomla back end, there is a "x-cart connector" function which will define the Correlation of CB fields and X-cart profile fields. We strongly advise you to create the same x-cart and CB fields. 7. Our integration does not include template modification, if you need that service, please feel free to contact us, and we are happy to provide designing service too.
