{id_?}

{id_?}
criterion allows all possible joins to be made with environment variables. It therefore behaves as many criteria{id_xxx ?}` as possible
for the given loop.
For example the loop <BOUCLE_liste(ARTICLES){id_?}>... will be understood
as
<BOUCLE_liste(ARTICLES){id_article?}{id_rubrique?}{id_secteur?}{id_trad?}{id_mot?}{id_document?}>...,
varying according to the possible links, and therefore according to the
active plugins. The writing is therefore much more concise.
For a loop on a given table, the links created take into account:
– the link table if it exists (for example spip_mots_liens for
spip_mots)
– `objets
,
id_objetfields otherwise (for example forspip_forum`).
Keys objet,id_objet
On a table with the fields objet and id_objet (as spip_forum), both
the {objet?} criterion and the {id_objet?} criterion will be applied.
Installing and uninstalling plugins
{id_?} criterion allows to write identical loops whatever the active
plugins. Indeed, some plugins create tables and allow additional
conditional joins on these tables, but if we integrate these joins in a
loop using the identifier of this table {id_latable?}, uninstalling this
plugin will cause a compilation error. With {id_?} criterion, the joins
are done automatically and without error whatever the plugins installed or
not.
