Check that value of the $field->name is not Null. Isset will return false if variable is null.
For objects I suggest to use property_exists instead of isset.
Me myself prefer to use template engine instead of using php code in view files.

The problem is that $field->name is not null but a string form a ORM object ,isset return false,Is there a shortcut for property_exists method in volt?

I think there is no volt function for property_exist. You need to add custom function to volt compiler.
