Build a logout and redirect link

Hello

We would like to build a standard link which when clicked would allow the user to be automatically logged out and redirected to the registration page.

Can we do it with CB ?

Would you have an idea ?

You'd have to format the &return parameter for the logout URL or use a Login / Logout auto action in CB Auto Actions. Below for example should work.

Global
Triggers: None
Type: Login / Logout
User: Automatic
Access: All Registered Users
Action
Mode: Logout
Redirect: [cb:url location="registers" /]

If you don't want to use an auto action you'll need to add the &return to the logout URL yourself. To format the &return you'll need to take the URL you want to redirect them to and base64 encode it then prefix it with B: then add that to the &return in your logout URL.

Thanks a lot !

I'd rather use the auto action but I have one more question.

On the page where the user is we would like to get a cb field to pass to the register url.

I tried to add ?atid=[cb_codeatid] to [cb:url location="registers" /] but of course as there is no longer an user object on the registration page opened, the field is empty.

Do you have a suggestion to cleanly pass this field to the redirection before the log out ?

It seems also that a message/alert is not displayed on the registration page (though it works well on other CB pages when we try)

You don't have to use the URL substitution. You can supply the URL yourself beginning with index.php like the following.

index.php?option=com_comprofiler&view=registers&Itemid=MENU_ID&atid=[cb_codeatid]

Be sure to replace MENU_ID with the menu id for your registration menu item or the URL likely won't SEF nicely if using SEF.

That's a known issue with no fix at this time. Joomla wipes the session where messages are queued so it can't display anything unless the message is queued after the session has been regenerated as a guest session on the next page load, but by then it's too late.
