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 .) |
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) |
File | choose from .txt, .xlsx, .xls, .docx, .doc, .pdf, .psd, .svg, .eps, .png, .jpg, .jpeg, .gif, .ico, .mp4, .mov |
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.
