Validate a number field
The number validation checks the values of a field are within a specified range. You can define a range by specifying the minimum and the maximum values (the values are included in the range). Alternatively, you can specify only minimum or maximum value to set a limit on the minimum/maximum allowed value.
How to set the validation
With a content type open for editing:
- Select the number or decimal field you want to set a validation rule for and select the Validation tab from the Field Settings panel.
- Set a value for the minimum, maximum, or both fields to set a range of values.
Minimum allows you to set an expected minimum value that needs to be met. For example, Requires a minimum value of 10.
Maximum allows you to set the maximum value that can be set in the field. For example, Requires a maximum value of 100.
Minimum and maximum allows you to set a range of values that can be set in the field. For example, Requires a value between 10-100.
You can add an alternative validation message by entering it in the validation message text box for each value. This will be displayed if the field fails validation when published.
