SPIP can send warning messages for various events that may be more or less considered as being urgent:
-* A database crash
-* A plugin crash
-* A plugin activation error
-* A notification that there is a message in the mailbox
This pipeline, called in
ecrire/inc/commencer_page.php by the
alertes_auteur() function, is used to populate the table containing such warnings.
$alertes = pipeline('alertes_auteur', array(
'args' => array(
'id_auteur' => $id_auteur,
'exec' => _request('exec'),
),
'data' => $alertes
)
);
It receives an array as a parameter.
-*
data: contains an array of the various warnings,
-*
args contains an array with:
-**
id_auteur being the currently logged-in author,
-**
exec is the name of the displayed page.
Example
Suppose that there is a plugin called "Watch out for llamas", which tells people that they are at risk of encountering a fearsome llama, then we could provide this as follows:
function llamas_alertes_auteur($flux){
$alertes = $flux['data'];
// If there is a llama in front of this author
if (tester_llama($flux['args']['id_auteur'])) {
// We add a warning
$alertes[] = "<strong>Watch out! There's a llama!</strong>";
}
// We return the table of warnings
return $alertes;
}
A most fortuitous and beneficent plugin indeed!
