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.
e.g. Requires between 200 - 300 characters
Minimum of allows you to set an expected minimum value that needs to be met.
e.g. Requires a minimum of 200 characters
Maximum of allows you to set the maximum number of characters that can be entered.
e.g. Requires a maximum of 200 characters
- 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.
