Validation schema example

This schema example demonstrates various validations available for text, numbers and arrays.

• The simplestringwithmaxandmin property uses minLength and maxLength to constrain the length of the string. This property is also included in the properties listed as required, so a valid value must be entered in the property before it can be saved.

• The dateWithPattern and urlslug properties demonstrate how to constrain the value entered using a regular expression defined by the pattern keyword. You can find out more about regular expressions in JSON Schema in the JSON Schema documentation.

• The numbervalidationexample shows how to use the multipleOf keyword, for a number that must be a multiple of 10

• The stringlistofenums demonstrates how to use an enum to constrain the values that can be added to a list. The uniqueItems keyword is also used to ensure that each value can only be chosen once. This property is also required, so a valid value must be entered before the the content item can be saved. Users have a choice of selecting "none" if the array uses an enum.

• The stringArray must contain a string with a length of 10 or more characters - validated using the contains keyword.

• The numberArray property must contain an integer with a value of at least 10 - validated using the contains keyword.
