commit, SQL, api, documentation
3 new functions enable to create and delete views for PG, SQlite and MySQL :
- sql_get_select() : same arguments as sql_select() but returns the query without evaluating it
- sql_create_view($view_name, $select_request) : creates the view $view_name for the select request $select_request.
- sql_drop_view($view_name) : drops the view.
/!\ Warning ! Yous must give an explicit name to every field prefixed with a table name or an alias. Elsewhere SQLite won't be able to read the view (which contains 'a.titre' instead of 'titre').
Example :
$sel = sql_get_select(
array(
'id_article'=>'id_article',
'titre'=>'titre'
),
'spip_articles');
echo "requete select : $sel<br />";
sql_create_view('vue_nom', $sel);
$res = sql_select(array('id_article', 'titre'),'vue_nom',,,,'10');
if ($res){
while ($r = sql_fetch($res)){
echo "*" . $r['id_article'] . " - " . $r['titre'] . "<br />";
}
}
sql_drop_view('vue_nom');

plugins, api, documentation
During the normal execution of several commands, call-outs are made to optional scripts that allow a developer to add functionality or checking. Typically, the hooks allow for a command to change the values of function arguments before any other call, and allow for a post-processing treatment that will always change the function result.
Exemple :
function prefix_treatment($flow) {
/* add something to the flow */
$flow .= 'This is some html code';
return $flow;
}plugin.xml defines the implemented hooks with a list of
<pipeline> tags:
<pipeline>
<nom>point_entree</nom>
<action>fonction</action>
<inclure>fichier.php</inclure>
</pipeline>
- <nom> : name of the hook (from a list defined in ecrire/inc_version.php)
- <action> : function name without it's prefix
- <inclure> : file name that defines the previous function. It's name must be prefix_action
