users table extension

[kmchen]

Hi

I need to add parameters to joomla users for a custom component. What is the best method to do that without directly touching at joomla core nor ##__users table ?

Thanks for any information

The simplest way is to store custom parameters along with core parameters in #__users table params column. But this is no good if you need data to be searchable. In that case, use #__user_profiles or custom table.

Thanks for your reply.

I found that for joomla 2.5: https://docs.joomla.org/Creating_a_profile_plugin

Will it work with joomla 3 and 4 ?

Will the new fields appear in the search engine of the users administration ?

The user object is shared by different extensions. How to avoid to reload it each time needed.

Are users's parameters registered into sessions?

Are sessions loaded in RAM only once until user logout?

What would be the best way to include those users extra parameters in session ?
