Manual:Block and unblock/cs

Dostatečně privilegovaní uživatelé (obvykle sysops) mohou blokovat a odblokovat IP adresy a uživatelské účty z úprav, nahrávání souborů, pohyb stránek, a pokud ano jim byla udělena taková práva, která chrání/odstraňuje ochranu a maže/obnovuje stránky.

MediaWiki handles blocks through an abstraction layer; extensions can add their own block types. The mechanism for creating/updating/removing blocks and how they are logged and listed are different for each block type; the mechanism for checking whether a user is blocked, preventing blocked actions and informing the user is unified.



Standardní blokovací rozhraní
Bloky jádra MediaWiki se aplikují prostřednictvím formuláře na speciální stránce $blok. Aplikaci bloku lze provést v několika krocích:


 * 1) Zadejte IP adresu nebo uživatele, který má být blokován. Do pole "" formuláře zadejte IP adresu, která má být zablokována, nebo název registrovaného uživatelského účtu, který má být zablokován. Všimněte si, že neexistující uživatelská jména mohou být také blokována, takže se ujistěte, že máte správné uživatelské jméno. Můžete také blokovat řadu IP adres. Pokyny viz.
 * 2) Zadejte parametry bloku. Vyberte akce, v jejichž dokončení má cíl bloku zabránit. Blok  brání cíli bloku upravovat všechny stránky na wiki, zatímco blok  brání cíli bloku upravovat zadané stránky a/nebo stránky v zadaných jmenných prostorech.
 * 3) Zadejte dobu trvání bloku. Předdefinovanou dobu trvání můžete vybrat z rozbalovacího pole označeného "" nebo můžete zadat vlastní hodnotu pomocí [standardního formátu http://www.gnu.org/software/tar/manual/html_node/Date-input-formats.html GNU] do pole "Other time" (jiný čas). Pokud je daná doba trvání "neurčitá", pak blokování nevyprší, ačkoli IP adresa nebo uživatelský účet mohou být stále odblokovány sysopem.
 * 4) Zadejte důvod zablokování (volitelné). Tento důvod se zobrazí blokovanému uživateli, pokud se pokusí upravit stránku.

Kliknutím na "" použijete blok. Všechny bloky jsou zaznamenány v bloku a všechny aktuálně aktivní bloky jsou uvedeny v seznamu aktivních bloků.

Všimněte si, že kromě ručního zadání IP adresy nebo uživatelského účtu, který má být zablokován do Special:Block, můžete také použít odkaz "" z panelu nástrojů v postranním panelu při prohlížení "Uživatelské" nebo "Uživatelské diskusní" stránky IP adresy nebo uživatelského účtu. Můžete také kliknout na odkaz "" za IP adresou nebo názvem uživatelského účtu v seznamu posledních změn nebo v historii stránek.



Možnosti blokování
Ve verzi 1.8 MediaWiki bylo přidáno několik dalších možností blokování, které jsou povoleny zaškrtnutím políčka ve formuláři blokování.


 * Blokovat pouze anonymní uživatele (nazývané také softblocking)
 * Tato možnost změní účinek blokování při blokování adresy IP. Když je povoleno, blokování ovlivní pouze úpravy anonymních uživatelů z dané IP adresy. Úpravy registrovaných uživatelů z této IP adresy nebudou ovlivněny. Volba nemá žádný vliv na blokování registrovaného uživatele, ale má na jím způsobený autoblok.


 * Blokovat vytvoření účtu
 * This option changes the effect of a block when blocking a user or an IP address. When it is enabled, the registration of new user accounts from that IP address will be disabled while the block is in effect. However, this can be bypassed by creating an account on another wiki and visiting the wiki where the block is active, as global accounts automatically create local accounts on wikis the first time they are visited by the user. However, the bypassing can be prevented by a global ban that prevents account creation.


 * Automatically block the last IP address used by this user, and any subsequent addresses they try to edit from (also called hardblocking)
 * This option changes the effect of a block when blocking a registered user account. When it is enabled, the IP address most recently used by the account, and any IP addresses that the account subsequently attempts to edit from will be automatically blocked.

Partial blocks
Since MediaWiki 1.33, it is possible to prohibit the block target from making changes only to the specified pages and/or all pages in namespaces. If a page is moved, the restriction will be switched to the new title. Currently non-existent ("redlink") pages cannot be blocked, and setting multiple overlapping blocks with different expiration dates is not supported.

In MediaWiki 1.33 and 1.34, partial block is disabled by default. It may be enabled by setting.

Since MediaWiki 1.35, partial blocks are always enabled and cannot be disabled. You may hide partial blocks form elements by adding some JS or CSS to user or site common.js/common.css. This does not disable partial blocks which may still be set via API.

Unblocking
An IP address or registered user account can be unblocked via the list of active blocks. Find the IP address or registered user account you wish to unblock in the list (you can enter the address or name in the "" field to help you find the entry), and click the "" link displayed to the right of the block's expiry time.

This will lead you to a confirmation page. Enter the reason for unblocking (optional) in the "" field, and click "" to remove the block. All unblockings are recorded in the block log.

Note that if a range is blocked, then the unblock must cover the whole range to be effective. Attempting to unblock an individual IP address in the range will not be effective.

Effects of being blocked
When is enabled, blocked users are locked out of their account entirely. This is mainly meant for private wikis which need a mechanism to revoke reading privileges once a user is not active anymore.

On other wikis, blocked users may still read pages, but they may not create, edit or move pages, or upload files. Partially blocked users may not edit the particular pages or namespaces specified in their block, but may create, edit or move other pages, and may upload files. Users with certain other user rights may not be able to use those rights when they are blocked, depending on their block. For example, users with the rights to delete and undelete or protect and unprotect pages will not be able to do so if they are sitewide blocked. If they are partially blocked, then for any page they are not blocked from, they will still be able to perform these actions. However, users with the rights to block and unblock users will still be able to do so when they are blocked. Unblocking your own account requires the extra right  ; by default all sysops have this but on large wikis it might make sense to remove it to make potential account takeovers less disruptive.

Users who are blocked and attempt to edit a page (or move a page, or upload a file) will see the "Your account or IP address has been blocked" message informing them that they have been blocked.

If the autoblock option has been enabled with respect to a block, and the blocked user attempts to edit (or move a page, or upload a file), the IP address being used by that user will also be blocked.

Configuration settings related to blocking
The configuration options below can be set in and can be used to enable or disable certain aspects of the blocking interface.
 * - controls how many seconds need to pass until a block on an "autoblocked" IP address will expire. The default is 86400 seconds (one day)
 * - controls whether or not a blocked user is able to edit their own user talk page. This is currently (1.26+) true by default. The ability to disable the ability of a blocked user to edit their own user talk page, when this variable is true, is an option available in Special:Block.
 * and the blockemail user right control the ability for sysops to prevent users from using the Special:EmailUser interface. is true by default.
 * - controls if blocked users will be prevented from logging in. This is false by default.
 * - (1.29+) determines whether to set a cookie when a user is autoblocked. Doing so means that a blocked user, even after logging out and moving to a new IP address, will still be blocked. This is false by default.
 * - (1.33+) - allow the creation of partial blocks, which can block a user account, IP address or IP range from particular pages, namespaces or actions. This is false by default.
 * The hideuser user right controls the ability for sysops to prevent a blocked user from appearing in the block log, the active block list, and the user list.

Default block duration options
To change the default options listed in the "Expiration" drop-down menu, edit the page MediaWiki:ipboptions. The options are stored as a comma-separated list of "label:value" strings, for example. To have three options listed in Spanish, the page could include.

The default duration is "other". To specify another default duration, edit the page MediaWiki:ipb-default-expiry and enter the value you want. Note that you must write the value and not the label, if you were using the Spanish example listed above, MediaWiki:ipb-default-expiry should be  (the value) and not   (the label).

To specify a default duration for anonymous users, edit the page MediaWiki:ipb-default-expiry-ip and enter the value you want. Using the Spanish example listed above, you could write  (the value) but not   (the label).

URL parameters
Special:Block accepts some URL parameters to prepopulate the HTML form:


 * - username/IP address
 * - the type of block restriction (=sitewide or =partial)
 * - the pages to block (only applies for partial blocks; separate multiple pages with %0A; maximum 10 pages)
 * - IDs of the namespaces to block (only applies for partial blocks; separate multiple namespaces with %0A; see for a list of blockable namespace IDs)
 * - expiry time
 * - autoblock setting (=1 or =0)
 * - hard block setting (=1 or =0)
 * - prevent account creation (=1 or =0)
 * - reason, from selection of MediaWiki:Ipbreason-dropdown
 * - prepopulating "other reason" text field

Hooks

 * - occurs whenever the software receives a request to block an IP address or user
 * - occurs after the request to block an IP or user has been processed
 * , - like BlockIp/BlockIpComplete, for unblocking
 * - occurs when creating an autoblock, allows extensions to cancel
 * - similar to AbortAutoblock but called when doing a retroactive autoblock (when performing a block, also autoblocking the user's last used IP)
 * - when the software checks for blocks, can be used to modify existing blocks or implement new types of blocks
 * - deprecated, similar to GetUserBlock
 * - can be used by extensions which reimplement user talk pages in some way (e.g. ) to honor the "allow the user to edit their own talk page" flag
 * - similar to GetUserBlock, but for global blocks (which are for historical reasons handled separately)
 * , - allows cross-linking Special:BlockList and Special:AutoblockList respectively with similar special pages provided by extensions
 * - allows modifying the core Special:Block form

SQL
All types of blocks are stored in the  table, not just IP blocks. Only currently active blocks are stored here. To see old blocks, check the  table. is a string and can be a username, an IP address, or blank. contains the  of the blocked user. Here is how to filter for different kinds of blocks:


 * User blocks –
 * Auto blocks –
 * Address blocks –
 * Range blocks –
 * Partial blocks –
 * Blocks that are indefinite –
 * Blocks that expire –
