Question

hello I get crazy through a header-function that does not work.

the idea is that when a user is calling the page foo.php he will be headered. therfor I included a script from script.php

the script reads out the information about the accepted languages from

$_SERVER[“HTTP_ACCEPT_LANGUAGE”])

okay, from that I have the preferred language and a country code that I need to header foo.php into the right language direction. the code from script.php is like:

if ($pref_language == 'af'){
    header('Location:en'.$_SERVER['SCRIPT_NAME']);
    exit;
}
if ($pref_language == 'sq'){
    header('Location:en'.$_SERVER['SCRIPT_NAME']);
    exit;
}

so these examples will header foo.php to directory of

root/en/foo.php

now when calling just script.php that is located in root/scripts/script.php I will headered root/en/scripts/script.php. thats why I would like to add the if-condition that
all if-statements with header(); only take place for files outside of root/scripts/.

so I added:

$filename = $_SERVER['SCRIPT_NAME'];
$path = $_SERVER['HTTP_HOST']."/scripts".$_SERVER['SCRIPT_NAME'];

if (isset($path == false)){

    if ($pref_language == 'af'){
        header('Location:en'.$_SERVER['SCRIPT_NAME']);
        exit;
    }
    if ($pref_language == 'sq'){
        header('Location:en'.$_SERVER['SCRIPT_NAME']);
        exit;
    }
}

that does not work. so if someone could help me out I really would appreciate.

thanks alot.

This can be your solution, although it’s kind of silly in a way, but will do the job:

<?php

$unwanted_dir = "/scripts";

// this will make sure that the script name doesnt start with "/scripts" 
if (substr($_SERVER['SCRIPT_NAME'], 0, strlen($unwanted_dir)) != $unwanted_dir){

    if ($pref_language == 'af'){
        header('Location:en'.$_SERVER['SCRIPT_NAME']);
        exit;
        }
    if ($pref_language == 'sq'){
        header('Location:en'.$_SERVER['SCRIPT_NAME']);
        exit;
        }
}
?>

another way would be a regular expression, but this is simplier

I advise you to make it more dynamic on selecting the language. i.e:

<?php

$unwanted_dir = "/scripts";
$pref_language == 'af';  // dynamicaly set the language
$full_path = '/home/php/site/';

// this will make sure that the script name doesnt start with "/scripts" 
if (substr($_SERVER['SCRIPT_NAME'], 0, strlen($unwanted_dir)) != $unwanted_dir){

    if (is_dir($full_path . $pref_language)){
        header('Location:'$full_path . $pref_language . $_SERVER['SCRIPT_NAME']);
    }
    else{
        echo "Sorry, we don't support your language";
        // or
        // header('Location:go/to/unsopported/languages.php');
    }

    exit;
}
?>
