problem retrieving data from forms

harmic79

I am having problems retrieving data from forms. This is the code I used:

<html>
<body>

<form action="<?php echo $PHP_SELF;?>" method="POST">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" name="submit" value="submit"/>
</form>

<?php
$name = $POST['name'];
$age = $POST['age'];
$cons = 5;
?>

-<?php echo $_POST ?>-

<p>|<?php echo $name; ?>|</p>
<p>|<?php echo $age; ?>|</p>
<p>|<?php echo $cons; ?>|</p>

<?php phpinfo(); ?>

</body>
</html>

I was using some examples from some tutorials, but I don't see what I am doing wrong. The reason $cons is there was to just make sure I wasn't doing somehting really dumb.

This is the output:

Name: Age:

||

||

|5|
PHP Logo
PHP Version 4.0.6

What am I doing wrong? (also, I have no control over what version of PHP is being used)

Take a look at this manual page for more information about getting data from external sources: [man]variables.external[/man].

Also note that $PHP_SELF is never defined. Perhaps you meant $_SERVER['PHP_SELF']? Honestly, if you're doing tutorials and they suggest code like the above, you should immediately ditch those tutorials and find decent, up-to-date ones (e.g. not ones that use coding practices that have been deprecated for years).
