Hi,
I use
$view = views_embed_view('export_emargement','page_1',$journee,$region,$produit);
it works well, but If I don't want to specify $region the view does'nt works.
Im my view admin if I set argument like this 797/62/24 it works
If I try 797/all/24 it works too!every data are displayed
In my code i try this, but it can't be parsed
