TYPO3: what is the field “access_group” for?

问题

I don't know what is the field "access_group int(11) DEFAULT 0 NOT NULL" for? First I thought it's for restriction by user_group, but there is an field "fe_group varchar(100) DEFAULT '' NOT NULL" for it. You can find the field also at the documentation Preparing the database , but I couldn't find a description for it, only for "fe_group".

回答1:

access_group is the be_user group.

In TYPO3 you have an access-system similar to the unix-rights, where you can grnat access to pages (and records in the page).

There is a menu entry System->Access where you select a page and can set values for multiple levels recursive:

You can set Owner and Group and the granted rights which are assigned for
Owner, Group, Everybody

the rights are coded bitwise (other order than displayed):

1 (2^0) Show page: Show/Copy page and content.
2 (2^4) Edit content: Change/Add/Delete/Move content.
3 (2^1) Edit page: Change page eg. change pagetitle etc.
4 (2^2) Delete page: Delete/Move page and content.
5 (2^3) New pages: Create new pages under this page.

These values can be set with TCEMAIN in the page TSconfig, so all pages in a sub tree might get the same rights.

Example:

TCEMAIN.permissions {
    userid = 43
    groupid = 5
    user = 31
    group = 19
    everybody = 1
}

• Each page will get the user with the uid 43 as owner,
• the group will be the group with the uid 5,
• the owner has every right,
• the group can show page, edit page, edit content but can not delete page or create new pages below
• every one else can see the page

Alternatively you can set the rights by keywords:

TCEMAIN.permissions {
    userid = 43
    groupid = 5
    user = show, edit, delete, new, editcontent
    group = show, edit, editcontent
    everybody = show
}

comment from Rudy Gnodde, which I agree:

This is only used for pages, not in custom tables for extensions. It's probably a mistake in this documentation. It should be fe_group I think (which is mentioned in this documentation, but not in the code example which contains access_group).

As TYPO3 manuals can be edited by everyone (there is a button Edit me on GitHub in the upper right corner), I have proposed a correction.
