Question

I’ve seen <form> opening tags that look like this:

<form action="<?= $_SERVER['REQUEST_URI'] ?>">

Does the action attribute here make any sense?

Wouldn’t the form behave the same way without it?

Answer 1

You should always include the action attribute in your form tag if you want a good valid markup (which you should). It is a required attribute (though most browsers will work around it if you don’t and assume action="").

Using:

<form action="" method="post">

…will work and just use the current page as the action page.

Hope this helps.
