Using 'required' makes the field always required.

Using 'nullable' allows empty values even when required.

💡 Hint

Common Mistakes

Using 'required_if' expects a specific value, not just presence.

Using 'required_without' triggers when the other field is missing.

Using 'sometimes' does not enforce requirement.

The required_with rule requires the field only if another specified field is present.

💡 Hint

Common Mistakes

Using '=' or '==' instead of a comma.

Omitting the value after the field name.

Using only the field name without value.

The required_if rule syntax is required_if:otherfield,value. Commas separate the field and value.

💡 Hint

Common Mistakes

Using 'required_without' instead of 'required_with'.

Mixing up the order of rules.

Using 'nullable' which allows empty values.

required_if checks the value of 'country'. required_with requires 'address' if 'state' is present.

hard

Fill all three blanks to require 'discount_code' only if 'user_type' is 'member', 'purchase_amount' is greater than 100, and 'promo' is present.

]);

💡 Hint

Common Mistakes

Using 'required' alone makes the field always required.

Using 'required_without' instead of 'required_with'.

Using '=' instead of ',' in rule parameters.

required_if checks 'user_type'. gt checks if 'purchase_amount' is greater than 100. required_with requires the field if 'promo' is present.
