check box question

[eurob]

part of my html

<form action="process.php" method="post">
Check box field: <input name="showit[]" type="checkbox"  value="whatever">
<input type="submit">

 

//process.php

<?php 
$showit = $_POST['showit']
?>

If I don't check the check box I get the error 'undefined index'.
How can I still capture the check box value, regardless if I checked it or not? 

Thanks,
robert

process.php

 

<?php
if ( isset($_POST['showit']) ) {
    $showit = $_POST['showit']
}

 

Undefined index is only a notice, nothing fatal. You can ignore those, but if you want to program correctly, you need to test if a variable exists before working with it directly.
