Variable content gets lost

[pesto]

part of my code:

 

-----------------------------------------

var_dump($adr);

echo "<BR>";

 

function print_form() {

global $error, $print_again, $page, $vorn, $name, $adr, $abs, $betr, $mess, $empf;

 

var_dump($adr);

echo "<BR>";

-----------------------------------------

 

The first var_dump($adr) prints out a value (21 for example).

The second var_dump($adr) has no more value, is prints out NULL.

 

Can someone please tell me why?

It's generally a bad idea to use global variables better would be to pass the variables as parameter to function. About your problem I cant see you calling that function anywhere`: print_form(); ? You just define the function but never call it or is there more code to this?

 

<?php
// define a function
function sayHello()
{
    echo 'heello!';
}

// call the function
sayHello(); // actually prints out that heello!

/***** MAIN *****/

if(isset($submit)) {

check_form();

} else {

print_form();

}

 

 

The script runs perfectly in PHP4, but no more in PHP5.

You probably had register globals on in your older installation of php. Since now you have to use $_POST['submit'] instead of $submit if your form is using POST method. $_GET global array wil have GET variables and $_REQUEST both POST and GET.
