PHP Form Action Self submit

A question I am always asked is about ‘self-submitting’ forms.

I’ll start off with the code!

myform.php

I want to :

In the above, this will simple subit the form and then you can do what you want with it. For example display some data, or if the form was to create a user account to insert that.

OK… you can also process the form depending on what’s been selected/entered and so on.

myform2.php

I want to :

in this example if you select something, say ‘watch a movie’ and submit it, it will display: “Process ‘watch a movie’.”.

Some additional enhancements:

—————————–

The form action of course does not need to itself… you can put anything in action=”” if you prefere to process the form seperatley.

<form action=”…” method=”post”>

In my examples I have displayed the form only if it’s not submitted, this can also be done how you choose. Generally these would be:

ex1: form always present (below any resulting processing)…

<?php

if(!empty($_POST[‘submit’])) {

// Process form

}

// Show form

?>

ex2: form always present (above any resulting processing)…

<?php

// Show form

if(!empty($_POST[‘submit’])) {

// Process form

}

?>

ex2: show form only if not submitted

<?php

if(!empty($_POST[‘submit’])) {

// Process form

} else {

// Show form

}

?>
