Variables in functions

[Anon]

If I set variable $obj_realname in function called check_realname how can I bring him out in a function called check_ok ?

Thanks, Arni

Try these two method. Set $obj_realname as global variable, like this

global $obj_realname;

function check_realname(){
global $obj_realname;
}

function check_ok(){
global $obj_realname;
}

OR simply put $obj_realname as static variable

function check_realname(){
static $obj_realname;
}
the $obj_realname value should not be lost even after out of the function, but i am not sure whether this work just try and good luck.

Ok I'll post the functions here,...

function check_realname($real_name) {
global $obj_realname;
trim($real_name);
if(!$real_name) {
echo '<font color="red">ERROR - Real name missing</font><br>';
return false;
} else {
echo 'Realname: <i>'.$real_name.'</i><br>';
echo '<input type="hidden" name="Creal_name" value="'.$real_name.'">';
$obj_realname = '1';
}
}

function check_ok($sub) {
global $obj_realname;
if($obj_realname == '1') {
if($sub == 'form') {
echo '<form method="post" action="do_form.php">';
} elseif($sub == 'submit') {
echo '<input type="submit" name="submit" value="submit">';
}
} else {
return 0;
}
}

These to are in an include file called user.php and when I include the file I want to check NOT from this file but from the file I include this file.. 🙂

Any ideas?

Im not exactly sure what it is you are trying to do, but couldnt you just return the value of $realname? Something like this:
function check_realname($realname){
$realname = trim($realname);
if(!$realname){
echo 'ERROR - Real name missing<br>';
return false;
}else{
echo 'Realname: '.$realname.'<br>';
return $realname;

}
}

And then...

function check_ok($sub,$newrealname) {
if($newrealname) {
if($sub == 'form') {
echo '<form method="post" action="do_form.php">';
} elseif($sub == 'submit') {
echo '<input type="submit" name="submit" value="submit">';
}
return 1;//if you are using the returns for anything
} else {
return 0;
}
}

and finally call the functions...

$test1=check_realname($somevariable);
$test2=check_ok($sub,$test1);

Hope this helps
