I have not solved my problem. I think the problem is not a template list issue (JB slick list)
In my parent list I have a before render code :
$x = $fields['fic_mois']->value;
$sDateDebut = date("Y-m-d", mktime(0,0,0,date("m")-$x,1,date("Y")));
$sDateFin = date("Y-m-d", mktime(0,0,0,date("m")+1-$x,0,date("Y")));
$mois = date("F", mktime(0,0,0,date("m")-$x,1,date("Y")));
$fields['mplf_date_debut_mois']->value = $sDateDebut;
$fields['mplf_date_fin_mois']->value = $sDateFin;
$fields['fic_mois_lettres']->value = '
<h2>Biographies de '.JText::_($mois).'
</h2>
';
where fic_mois values are 1, 2, 3... 12
If I add an echo($fields['mplf_date_debut_mois']->value); echo($fields['mplf_date_fin_mois']->value);
values are ok : 2017-05-012017-05-31...
I added mplf_date_debut_mois, mplf_date_fin_mois and fic_mois fields in hidden position)
In parent list, I inserted a child list with a Seblod list field with this options :
mplf_publication_mois_max=mplf_date_fin_mois
mplf_publication_mois_min=mplf_date_debut_mois
where mplf_publication_mois_max and mplf_publication_mois_min are article created (and are added to child search form view)
But, if I put the debugging in child list, I get this :
SELECT t0.id AS pid,t0.pk AS pk,t0.pkb AS pkb,t0.parent_id AS
parent,t0.author_id AS author,t0.cck AS cck,t0.storage_location AS
loc,tt.id AS type_id,tt.alias AS type_alias
FROM `#__cck_core` AS t0
LEFT JOIN `#__content` AS t1 ON t1.id = t0.pk
LEFT JOIN `#__cck_core_types` AS tt ON tt.name = t0.cck
WHERE t1.state = 1
AND t1.access IN (1,1,2,3,6,7)
AND ( t1.publish_up = '0000-00-00 00:00:00' OR t1.publish_up <= '2017-06-12 11:07' )
AND ( t1.publish_down = '0000-00-00 00:00:00' OR t1.publish_down >= '2017-06-12 11:07' )
AND t1.created >= '2016-10-27 16:40:50'
AND t1.created < '2016-10-27 16:40:50'
AND t0.cck = 'mplf'
ORDER BY t1.title ASC
SELECT COUNT(t0.id)
FROM `#__cck_core` AS t0
LEFT JOIN `#__content` AS t1 ON t1.id = t0.pk
LEFT JOIN `#__cck_core_types` AS tt ON tt.name = t0.cck
WHERE t1.state = 1
AND t1.access IN (1,1,2,3,6,7)
AND ( t1.publish_up = '0000-00-00 00:00:00' OR t1.publish_up <= '2017-06-12 11:07' )
AND ( t1.publish_down = '0000-00-00 00:00:00' OR t1.publish_down >= '2017-06-12 11:07' )
AND t1.created >= '2016-10-27 16:40:50'
AND t1.created < '2016-10-27 16:40:50'
AND t0.cck = 'mplf'
and, of course no result because of created date (first article created date).
So what is the problem : before render field ? seblod list field ? Why mplf_publication_mois_max and mplf_publication_mois_min values are not those calculated by before render code ?
Before the update, it worked perfectly : Did I miss something ?
Thanks anyone could help me !
