{Dede: loop}. why is the [field: field/] blank when the field data is "0 ??? If you change 0 to any value, the corresponding value is displayed. if it is 0, it is displayed as null. thank you.

------ Solution --------------------
When the empty function in PHP checks whether it is null, 0 is also used as the null judgment, so it may be that {dede: loop} uses the empty function.
