Validating Nullable Fields |
Right now CI4 validation rules fail if the field is empty. So that they only work properly when the field is required. There should be a "nullable" rule to fix this problem. (I believe Laravel does this)
Otherwise null values should not fail validation by default. See this post https://forum.codeigniter.com/thread-685...#pid352959
Simpler is always better
We have the "permit_empty" rule. I think this is what you are looking for.
