PHP Form without additional File

Question

Is it possible to to have a PHP form without having a seperate file,

e.g. Normal Form

<form action="send.php" method="post">

But instead of calling send.php have the code held in send.php in the same file as the form?

Answer 1

Sure, just supply the action attribute with an empty action

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

or with a $PHP_SELF call.

<form action="<?php echo $PHP_SELF;?>" method="post">  

Both will submit to the current page.
