tu dis ligne 201, donc ca doit être ce foreach
foreach($rightsfiles as $rf){
$f = Judge::associated_file($rf);
if(($public_search and Judge::is_public($f))
or (!$public_search and Judge::view($f))){
if(is_file($f)){
return $f;
}else{
foreach(Menu::list_files($f,true) as $p){
if(($public_search and Judge::is_public($p))
or (!$public_search and Judge::view($p))){
return $p;
}
}
}
}
}si ce foreach envoie une erreur c'est peut etre parce que $rightsfiles est vide ou Null à cause de ce if
if(!isset($rightsfiles) || count($rightsfiles) < 1 ){
$rightsfiles = NULL;
}
