#51782 closed defect (bug) (worksforme)

Required in REST API register_rest_route args should check for empty string

Reported by: khr2003 Owned by:

When setting required key to true in register_rest_route it will only check for the existence of the key but not if value is empty.

I think the expectation is to check for both that the key is set with a value (that is not empty) has been set.

Hi @khr2003,

Welcome to trac and thanks for the ticket!

I understand this can be confusing, but it is the functionality required by the JSON Schema specification.

When you want a field to be required, and disallow an empty string, I'd recommend using the minLength keyword. For example:

        'type'      => 'string',
        'minLength' => 1,
        'required'  => true,

You can use the minItems keyword for arrays, minimum for numbers, and minProperties for objects.

@TimothyBlynJacobs Thanks, your suggestion worked.

I might add it to documentation to avoid confusion.

Good call, I'll make sure to add it when we refresh our documentation for 5.6
