How to use Validation: Contains

omidhz 07 Aug, 2019

I can't figure out how to use the validation "Contains" field. I want users to be able to enter numbers and letters only (No space or special characters), but I'm not sure what language/code should I enter here for that purpose.
Thanks

You need regex, not "contains".

/^[A-Za-z0-9]*$/

Thank you. That worked.
However, for my knowledge, what is the use for "contain" and how do you use it?

To make sure the contains a specific string
