When you edit a specific form field, you can add "extended validation". This lets you require that information be entered in a specific format before the registration data can be submitted.
In the example below, there is an input field where players should enter a receipt number. By adding a "minimum character" validation, you can require that the player enters a number that is at least 10 digits long.
When you add validation, you can add a validation message, which can help your players understand why their input was rejected and what the correct format should be. Read more here.
Types of validation
Only numbers | will only accept numerals 0 – 9 |
Only letters | will only accept letters (from almost all alphabets), space, and dash (-) |
Max characters | limits the number of characters |
Min characters | requires a minimum number of characters |
Own regular expression | lets you write a regex to control the input (this is an advanced setting) |
Valid phone | requires an 8-digit number (for other phone number formats, see example below) |
Valid email | requires a valid email address format (allows letters, numbers, and specific characters, checks that there is an @ symbol and a .)
In-depth email format validation

This format validation is by default used on the 'email' field type. For this field type, you also have the option of using the email validation service for verifying that the email address exists and can receive emails.

Remove special characters | will reject anything with the following characters: ЈҐў$Ђ¤©®§™°є+#µ<>%([)]??ї!?-'",.|`^«»«»~&:{;}
|
JavaScript event | lets you add a custom function (this is an advanced setting) |

|
Min. age | requires an age that is greater than or equal to the entered number
|
Min. date | disables dates in the calendar before the given date
|
Max. date | disables dates in the calendar after the given date

You can use more than one type of validation. For example, you can require a number that is exactly 12 digits long by selecting:
only numbers
max characters = 12
min characters = 12
But note that you can only write one validation message, so the message should explain the correct format clearly.
