hello i use session for save somme data like this foreach my $NumParc ( @NumParc ) { my $parc = database('toto')->quick_select('Parc', { NumParc => $NumParc }); $Stock->{$NumParc} = ( $NumParc => { CodeArticle => $parc->{CodeArticle}, NumParc => $parc->{NumParc}, NumSerie => $parc->{NumSerie}, NumContrat => $parc->{NumContrat} } ); session 'Stock' => $NewStock; but is a bit complex in the template for seleting my fial values the only things i can do is likke this [% FOREACH NumParc IN stack.keys.sort %] <tr> [% FOREACH item IN stack.$NumParc.values %] <td class="numcontrat">[% item %]</td> [% END %] [% END %] so i can not use item.keys to chosse my value like i hope [% FOREACH NumParc IN stack.keys.sort %] <tr> [% FOREACH item IN stack.$NumParc.values %] <td class="numcontrat">[% item %]</td> <td class="numserie">[% item %]</td> <td class="numParc">[% item %]</td> [% END %] [% END %] this is the json session file for stock - - "Stock": { - "768572": { - "NumParc": "768572", - "NumContrat": "zzzzzzzzzzzzz", - "NumSerie": null, - "CodeArticle": "SZZZZZtttttt" }, - "768573": { - "NumParc": "768573", - "NumContrat": "30912045", - "NumSerie": null, - "CodeArticle": "INST " }, - "768571": { - "NumParc": "768571", - "NumContrat": "12045", - "NumSerie": "1314ffffff374798", - "CodeArticle": "250efg" } }, the paste add bullet if someone may explain me a little where i am doing wrong ?
