SPIP commits

The SPIP team is really active and improve it regularly.
Here is a list of new functions that can help you develop plugins :

supprimer_objets_lies ( array($type, $id) ) :
Type : pipeline
Removes the objects of plugins linked to core objects (used when these core objects are deleted)

// http://doc.spip.org/@action_editer_message_post_supprimer
function action_editer_message_post_supprimer($id_message) {
        sql_delete("spip_messages", "id_message=".sql_quote($id_message));
        sql_delete("spip_auteurs_messages", "id_message=".sql_quote($id_message));
        pipeline('supprimer_objets_lies',array(
                array('type'=>'message','id'=>$id_message)
        ));
}

optimiser_sansref ($table, $id, $sel) :
This pipeline is called in genie/optimiser.php
It completes the removal process of orphelin objects.
(dead links between tables, that results from the suppression of articles, authors, etc)

example :

/**
 * Optimizes the database by removing orphelins forums
 *
 * @param int $n
 * @return int
 */
function forum_optimiser_base_disparus ($n){
       # detect forums that are linked to an id_rubrique that doesn't exist anymore
       $res = sql_select("forum.id_forum AS id",
                       "spip_forum AS forum
                       LEFT JOIN spip_rubriques AS rubriques
                         ON forum.id_rubrique=rubriques.id_rubrique",
                       "rubriques.id_rubrique IS NULL
                        AND forum.id_rubrique>0");

       $n+= optimiser_sansref ('spip_forum', 'id_forum', $res);
       
...
       
       return $n;
}

filtre_balise_img ($img, $alt="", $class="") :
