Manual:page_restrictions table

From mediawiki.org
(Redirected from Page restrictions table)
Manual:Contents MediaWiki database layout page_restrictions table
MediaWiki version:
1.10

The page_restrictions table is used to store page protection levels in MediaWiki 1.10 and later. The most notable feature is the introduction of cascading page protections for high-visibility pages. This table is for restrictions on existing pages only. Protections of non-existent pages are stored in the protected_titles table.

This table was introduced in MediaWiki 1.10 (r19095r19703), and overrides the page_restrictions field in the page table.

The list of protected pages can be found at Special:ProtectedPages.

Fields[edit]

pr_id[edit]

This is the primary key for the table, and is used to identify a particular row in the table.

pr_page[edit]

This field contains a reference to page_id , which works as the foreign key for this table.

pr_type[edit]

The type of protection (whether it applies to edits, page moves, or similar) is stored in this field.

pr_level[edit]

This column describes the level of protection for the page; full protection for sysop-only pages, semi-protection for autoconfirmed users, or any other levels.

pr_cascade[edit]

This field determines whether cascading protection (meaning that all transcluded templates and images on the page will be protected as well).

pr_user[edit]

MediaWiki version:
1.37

This field was reserved to support a future per-user edit restriction system, but was never used as partial blocks were implemented as blocks.

pr_expiry[edit]

This field contains the timestamp for pages whose protection has a set expiration date, and has a format similar to the expiry time in the Ipblocks table. Rows that contain a null value in this column are considered to be protected indefinitely.
