I wrote a simple form that checks to see if has been submitted or not.
The form works but when it is initially accessed, it give the variable $submit is undefined.
Is this the correct way to code a form with this feature?
Here's the code:
<body>
<?php
if ($submit) {
// process form
while (list($name, $value) = each($HTTP_POST_VARS)) {
echo "$name = $value<br>\n";
}
} else{
// display form
?>
<form method="post" action="<?php echo $PHP_SELF?>">
First name:<input type="Text" name="first"><br>
Last name:<input type="Text" name="last"><br>
Address:<input type="Text" name="address"><br>
Position:<input type="Text" name="position"><br>
<input type="Submit" name="submit" value="Enter information">
</form>
thanks
