Les Actions permettent d'ajouter de nouvelles capacités à votre Wiki. On parle aussi de plugins. Pour ne pas réinventer la roue, utilisez les fonctions déjà disponibles dans le coeur de Wikka. Vous gagnerez du temps et de la cohérence.

Décrivons maintenant ces fonctions. N'hésitez pas s'il vous plaît à compléter ces lignes (but de la fonction, ses paramètres, les résultats qu'elles retourne...). Ceci n'est pas la documentation officielle...


Texte fondé sur WikkaWiki version 1.1.5.3 package

Allons-y ! ...

Fonctions relatives à la base de données


Query($query)

reçoit une SQL Recherche en argument, l'exécute sur la base
Retourne les résultats.

LoadSingle($query)

reçoit une SQL Recherche en argument, l'exécute sur la base
Retourne la première ligne des résultats.

LoadAll($query)

reçoit une SQL Recherche en argument, l'exécute sur la base
retourne les résultats sous la forme d'un tableau (vecteur)

CheckMySQLVersion($major, $minor, $subminor)

Compare la version définie en argument par "$major.$minor.$subminor" à la version MySQL utilisée par votre PhP.
Retourne :
1 si la version utilisée est la même ou plus récente.
0 si la version utilisée est plus vieille.

Diverses fonctions utiles


GetMicroTime()

A utility function that is usefull to retrieve operation timing. Retourne (float).

IncludeBuffered($filename, $notfoundText = "", $vars = "", $path = "")

The main Actions loading function. It may come in handy in bigger modding projects on Wakka but for basic to novice Actions I can hardly thing of how it can be used. It executes the contents of a given filename ($filename) in a given path ($path) allowing for customising the error message in case of an error. Variables ($vars) are passed to the loaded file.

ReturnSafeHTML($html)

Reçoit des caractères (preferably HTML, hehe)
Retourne ceux-ci conformes aux standards XHTML.


Fonctions concernant les variables Wakka


GetPageTag()

Returne le nom ( tag, WikiPageName) de la page affichée (chaîne de caractères).

GetPageTime()

Returne la date et l'heure de création and time de la page affichée (chaîne de caractères : "2004-12-16 20:36:17").

GetMethod()

Returne la méthode (par exemple: WikiPage/edit) qui appelle la page affichée (chaîne de caractères).

GetConfigValue($name)

Returns the value from a configuration field ($name). Configuration is defined inside the wakka.conf.php file inside the wakka installation folder. It reruns a string when $name mathces any field of the configuration file or null if the configuration file doesnt have a $name field.

It also is responsible for passing the $vars array to the executed php script. The file has to have a .php extension in order to be executed by this function.

Format($text, $formatter = "wakka")
