[Resolved] Changed host now have an ifelse problem. why?

fr8

Moved to a new host and now im getting some php errors

The error:

Warning: main(Modules/.php): failed to open stream: No such file or directory in /home/dir/dir/dir/changeddomain.com/guest.php on line 51

if ( isset($usr) ) {
        $pathusr = "users/".$usr.".php";
                include ( $pathusr ) ;
}

If it finds a verible then it works great. But if it doesnt then I get the error.

maybe try

if ( isset($usr) && !empty(trim($usr))) {

That gave a me new error

Parse error: parse error, expecting T_VARIABLE' or'$'' in /home/dir/dir/dir/changeddomain.com/guest.php on line 44

What im going for is when the varible has something in it then it will pull the file that I want for the include. But if its not there then do nothing.

Hi,

please post the code you have so far (and check if one of the $ characters is missing => user instead of $user).

im assuming $usr is a get var attached to a url

if so looks like register globals is set to off when on old server they where on

use $_GET['usr'] instead of $usr

This is my current code.

$usr = preg_replace('/[^a-z]/i', '',$_GET['usr']);
$mod = preg_replace('/[^a-z]/i', '',$_GET['mod']);

if ( isset($usr) ) {
        $pathusr = "users/".$usr.".php";
                include ( $pathusr ) ;
}

if ( isset($mod) ) {
        $pathmod = "Modules/".$mod.".php";
                include ( $pathmod ) ;
        }

Sidney - I code as if RG is off. That way I dont have to worry as much on a host switch.

Hi,

what exactly do you want to replace with the preg_replace ? The first character of the GET variables if it is a-z or A-Z or all occurences of these characters ?

About the other problem ... try this code:

I changed the preg_replace.

$usr = preg_replace('/^[a-z]/i', '',$_GET['usr']); 
$mod = preg_replace('/^[a-z]/i', '',$_GET['mod']); 

if (isset($usr) && !empty($usr)) { 
        $pathusr = "users/".$usr.".php"; 
                include ($pathusr); 
} 

if (isset($mod) && !empty($mod)) { 
        $pathmod = "Modules/".$mod.".php"; 
                include ($pathmod); 
}

In this instance it doesnt really do anything. But at one point in time I went through all of my code I added the preg_replace where ever I grabbed something from the URL. That way I could control in some way of what can be sent in some of my querys. This was added to simple ones. Anything that needed only words or numbers in it. Which is just about the only thing I allow through the _GET.

Now on with the code that you provided. That worked perfectly. The only thing was I didnt use your replace string. Cut off the first letter.

Thanks for the help.
