Do I need to filter the feedback form?

Question

PHP

Good day. There is a site on wp, a handwritten feedback form is built into the page, there is no entry in the database, there are no files uploaded either, so you can not filter the data or is it still necessary? whether can fill in through the form somehow shell?

Answer 1

Of course, filtering is needed:

However, if you are too lazy to do filtering and validation, you can use ready-made APIs for sending emails:

Just don't be surprised if bots reset your balance and limits on sending emails in a day)
