Patterns (Regex) - Simple

The ReGex pattern allows us to implement Validation into your Text Field. Validation allows you to restrict what data is put into your Text box. For instance, we can restrict the user to characters ranging from A to H or to lowercase characters exclusively etc.

Presets and Validator

At the end of the entry box, you will see a button that allows you to open up more options to edit the pattern. You will the below screen that allows you to select a variety of preset options that will fill in the regex box, this can then also be added to if you want additional validation on the preset. If you are would like to make sure that the validation works without having to publish there is a test option that tells you if what you entered is valid.

Some Common Examples:

Alphanumeric without Spaces

/^[a-zA-Z0-9]*$/

Whole Numbers

/^\d+$/

UpperCase Letters with white space

[A-Z\s]+

LowerCase Letters with white space

[a-z\s]+
