Set a character count on a field
The number of characters validation rule checks that the number of characters in a text field meets a minimum or maximum value or is between a range of values.
How to set the validation
With a content type open for editing:
- Select the field you want to set a character count rule for and pick the Validation tab from the Field Settings panel.
- Choose one of the following options from the Number of characters dropdown:
Between allows you to set the minimum and maximum values for an expected character range.
Minimum of allows you to set an expected minimum value that needs to be met.
Maximum of allows you to set the maximum number of characters that can be entered.
- An alternative validation message can be added by entering it in the Validation message text box. This will be displayed if the field fails validation when published.
