任何浏览器都不会提交空白表单字段吗？

Question

When processing form input in PHP, can I safely assume that all form fields in the submitted form were sent through, or are there some browsers that will not even pass along blank fields?

Sorry if this is a common question, I just can't seem to find the answer.

Answer 1

Remember one rule: Don't trust anything out there!

Do not assume anything check alway everything which comes from a user and validate that values.

But yes normally it is send.
