How important is it from the point of view of common sense to specify the string rule in the validation rules?

Question

Laravel

I often see examples on the net where someone uses or does not use this rule.

Even in the Laravel source code itself, when registering a password, the required|string|min:8|confirmed rule applies, while when resetting a password, it is already required|min:8|confirmed.

Is it possible to imagine a scenario where the code could be sensitive to this difference?

Answer 1

For example, if an API is written in Lara that accepts data in json.
Not that it becomes a problem or a vulnerability, but it will help to catch the joint faster.
