Do you know all the validation rules available in Laravel? Think again! Laravel has many ready-to-use validation rules that can make your code life a whole lot easier. Let’s uncover the top 10 validation rules you probably didn’t know existed.

1. Prohibited

Want to make sure a field is not present in the input? Use prohibited.

'username' => 'prohibited',

If username is included in the request, validation will fail. Simple and effective, especially for a honeypot!

2. Prohibits

Need a field to prohibit another field from being present? Check this out.

'password' => 'prohibits:username',

If password is present, username must not be.

3. Required If

This one’s a lifesaver when you need conditional validation.

'email' => 'required_if:contact_method,email',

The email field is required only if contact_method is email.

4. Required Unless

Opposite of required_if. Use it to require a field unless another field has a specific value.

'email' => 'required_unless:contact_method,phone',

Here, email is required unless contact_method is phone.

5. Required Without

This rule is great when you need a field only if another field isn’t present.

'email' => 'required_without:phone',

If phone isn’t provided, email must be.

6. Required Without All

Step up your game by requiring a field if none of the other specified fields are present.

'email' => 'required_without_all:phone,address',

If neither phone nor address is present, email is required.

7. Starts With

Check if a string starts with a given value.

'username' => 'starts_with:admin,user',

The username must start with either admin or user.

8. Ends With

Similarly, check if a string ends with a specific value.

'username' => 'ends_with:_admin,_user',

The username must end with either _admin or _user.

9. In Array

Confirm a field’s value exists in another array field.

'selected_option' => 'in_array:available_options.*',

The selected_option must be one of the values in the available_options array.

10. Different

Make sure two fields have different values.

'new_password' => 'different:current_password',

The new_password must be different from the current_password.
