$_POST 1

chessbot · Nov 14, 2004

I've been searching the php.net documentation, but I haven't found anything useful.

If I have a check box without a value, such as this

Code:

<input type="checkbox" name="Bob_party">

and I reference $_POST['Bob_party'], what will it return if the value is checked? Unchecked? Not in the form? Are the last two different?

Here's the simple answer with an example:

Code:

<?php
print_r($_POST);
?>
<html><body>
<form method="post">
<input type="checkbox" name="testing">
<input type="submit" value="submit" name="go">
</form></body>
</html>

Please forgive the incomplete HTML.
However, when the box is cheked it is set to "on". The output shows

Code:

Array ( [testing] => on [go] => submit )

If it is not checked, it will be absent and the output is:

Code:

Array ( [go] => submit )

Hope that answers the question.

It does. Unfortunately.

I am looking for some way to have three possible states with one checkbox: not defined, checked, and unchecked. Is this possible without using hidden fields?

Unfortunately, no. You only have undefined and checked.
