passing on variables

[Anon]

Can anyone tell me how to pass on variables to a next file.

It's just the $price,and $name that i need to pass on. These variables are related to choice made by the the user. He/she also fills in a value of a number (which will become $amount in the next file) from a textfield embedded in "pure" html (not in a php section). The "pure" html variable is no problem with the post method. but how can i pass on the existing variables.

I thought that the following would work but it doesn't seem to do that:

<?
$fields = "price name";

foreach (explode(' ', $fields) AS $key => $val) {

print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';
}
?>

That works in my PHP:

<?
$fields = "price name";
$price = "3";
$name ="5";

foreach (explode(' ', $fields) AS $key => $val) {

print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';
}
?>

Though, one suggestion: explode() returns a numeric array, not an associative array, so you don't need the $key.

The problem is that my server run the php3 version of php. Do you know of any function that does the same but that is supported by php3.
