Help posts, ecshop non-members jump
This small white after the arduous hardships finally realized the Ecshop member registration background audit function
Now the problem is how to achieve non-members to browse the site only let him browse the homepage, click on other pages automatically jump to the member login interface, which code to embed, where to add? Do not understand ING. Ask for help AH ~ ~
------Solution--------------------
I didn't use Ecshop.
But I think this should be able to:
In the common class or in the portal file to determine whether the current user is a member, if not, the header to jump to login (exclude the case of opening the first page)
