I install PHP 4.3.3 on Xitami web server

This is the HTML form

and this is the PHP file

<?php
echo '<p>Order Processed at ';
echo date('H:i, F j');
echo '</P>';
$oil = $_POST['oilq']; <----PROBLEM. This is line 18
echo $oil;
?>

and this is my error when i run the page

Notice: Undefined index: oilq in C:\XITAMI\webpages\test\processorder.php on line 18

I try using $HTTP_POST_VARS[''] and $_POST[''] and still doesn't work. Also, i check the php by running the phpinfo(); and everything works fine but when i run my form is were php give an error. HELP!......Thank you for your time.

try without the "POST" just try

echo $oilq;

Try doing print_r( $_POST ) to see what is being posted.

Also, i try without "POST"

and it give me an error

Notice: Undefined variable: oilq in C:\XITAMI\webpages\test\processorder.php on line 19

Thanks for the tip but it didn't work.

HalfaBee

Well if that didn't display anything, that is why you are getting the error.

Are you trying to run processorder.php without calling it from the form?

The error is a notice, a minor one.

print_r() shows you that $_POST doesnt contain anything, i.e. nothing is send by the POST method.

You should check with

if (empty($_POST['oilq']))

if (!isset($_POST['oilq']))

Even i try running some source code that i download from the net and still doen't work. I bought a php book and i run some of their sample and still doesn't work.

Try this

<?
echo "Hello World my name is ";
if( isset( $_POST['test'] ) )
 echo $_POST['test'];
echo '<br>';
print_r( $_POST );
echo "
<br>
<form method=POST>
<input name='test' >
<input type='submit'>
</form>";
?>

Just cut and paste this and see what happens.
