| ↑ Manuel:Contenu | Schéma de base de données MédiaWiki | table externallinks |
| Version de MediaWiki : | ≥ 1.6 |
La table externallinks est l'endroit où MediaWiki range et suit les liens externes. Note unless $wgRegisterInternalExternals is enabled (it is disabled by default), links to the same server are not recorded.
Les liens qui dépendent du protocole sont rangés deux fois dans la cette table conformément à r102951.
Champs
el_id
| Version de MediaWiki : | ≥ 1.22 |
Clé primaire. Actuellement ne sert à rien, mais sera utile lors des modifications en ligne du schéma.
el_from
L' ID de la page qui référence la page wiki.
el_to_domain_index
| Version de MediaWiki : | ≥ 1.40 |
Ceci est similaire à el_index mais inversement inclut uniquement la spécification du protocole et le domaine, de sorte que http://en.wikipedia.org devient http://org.wikipedia.en..
el_to_path
| Version de MediaWiki : | ≥ 1.40 |
Uniquement le chemin de el_to.
Exemple :
/wiki/Main_Page
el_to
| Versions de MediaWiki : | 1.6 – 1.41 Gerrit change 954900 |
L'URL actuelle elle même. Elle est passée au navigateur.
el_index
| Versions de MediaWiki : | 1.6 – 1.41 Gerrit change 954900 |
C'est la même URL que el_to optimisée pour la recherche : les informations relatives au nom d'utilisateur et le mot de passe sont enlevées et les autres composants sont inversés pour accélérer la recherche, donc http://user:password@sub.example.com/page.html devient http://com.example.sub./page.html, qui permet les recherches de la forme 'Afficher tous les liens pointant vers *.example.com'.
el_index_60
| Versions de MediaWiki : | 1.29 – 1.41 Gerrit change 954900 |
Ceci équivaut à el_index tonqué à 60 octets, pour permettre les requêtes de tri non prises en charge par l'indexation partielle.
