REQUEST_URI was /test-post-simplest-form.php
POST was Array ( )
GET was Array ( )
This form has no button, nor attributes (method and action are empty). Its tag is very simple:
<form>You can verify this by viewing the source of this page.
Is it possible to submit the form using the Enter key? Try typing some text into the input, and then hit Enter. If the form was submitted, you'll see a question mark at the end of the URL (this does not happen in Firefox - instead, Firefox submits the form and empties out your input).This page was created in November 2019. I tested it in Chrome. If I type in some text, and hit the Enter key, the form submits, but no data is transferred to the server - the $_GET and $_POST variables are empty. So the form submits, but is not useful.
