Hi guys,

Does anyone nows a solution, 'cause I think there's a deprecated tag are something similar, because the book I'm using dates from 2005.

halojoy

you should test form 'submit' using

isset/B

// display initial form
if ( !isset( $_POST['submit'] ) )
{
?>
<tab

Hi,

Awesome! that is the solution, thank you!
But now, after posting a text, I'm receiving another message:
(but you have to know, the PHP book I'm using is old)

Title [
Notice: A non well formed numeric value encountered in C:\Users\Me\Desktop\UsbWebserver\UsbWebserver\Root\ch16\functions.php on line 6
12 Mar 2010]

edit | delete

And so, I checked my code, but it is similiar to what my book tells me,
but it still does not work.

functions.php:

<?php
// format MySQL DATETIME value into a more readable string
function formatDate($val)
{
    $arr = explode('-', $val);
    return date('d M Y', mktime(0,0,0, $arr[1], $arr[2], $arr[0]));
}
?>

Thank you,
