When submitting the laravel admin form and using the required verification, an error is reported when the value is 0

Recently used laravel-admin Write a project , The first contact with a trample hole is unavoidable , I happen to encounter a form submission , Data value transmission 0, The validation rule is required, But the prompt fails .

This makes many application scenarios of form submission not very applicable . So I decided to analyze laravel-admin Source code ,

At first, I thought it was filtered out during verification , As a result, it was wrong to debug for a long time ,

After some tossing and turning, I finally found my place , yes laravel-admin The form data of is assigned to Validator Object is filtered before ,

stay encore\laravel-admin\src\Form\Field.php Medium sanitizeInput() Method

because 0 stay php Is also considered an empty element, so it is filtered out ,

The solution is to give array_filter() Add the second parameter to use the callback function to filter , The specific code will not be written , It's simple .
