上传我的网站时出现PHP问题？

Question

I made a website on localhost. Then I uploaded it to different servers, and no problem. However, this time I tried to upload the web to another server, and in this one the code, which is exactly the same working on the other sites, does not work well. I was simplifying the mistake and must be in one of the following lines.

If I type on the URL my website, my code has to add the default language to the URL automatically (which is es ), if this one has not been specified yet. For example, if I type mydomain.com , it must be converted to mydomain.com/es .

Here the codes ( Note: lang was declared in htaccess, and is the name of the first parameter introduced on the URL, in this case, the language ):

index.php CODE:

<?php
    $idiomas = array("ES", "GL", "EN");
    if (!(isset($_GET['lang']) && $_GET['lang'] == "admin")) {
        require_once("pages/language.php");
    }
?>

language.php CODE:

<?php
    if (isset($_GET['lang']) && $_GET['lang'] != "") {
        switch ($_GET['lang']) {
            case strtolower($idiomas[0]):
            case strtolower($idiomas[1]):
            case strtolower($idiomas[2]):
            case 'admin':
                $_SESSION['lang'] = $_GET['lang'];
                break;
            default: {
                header("Location: ".ROOT);
            }
        }
    }
    else {
        if (!isset($_SESSION['lang']) || $_SESSION['lang'] == "") {
            echo '<meta http-equiv="refresh" content="0; url='.strtolower($idiomas[0]).'">';
            exit;
        }
    }
?>

Now, what is happening is: you type mydomain.com and this one is converted to mydomain.com/es on the URL, right, but it starts to do this each milisecond, reloading and reloading the page forever. I realised that when mydomain.com/es is already on the URL, in language.php the first condition of the if is not kept, and it should be kept.

I do not know why this code always worked in different servers and not in this one. Any idea, please? Thank you in advance.

Answer 1

As per your concern , URL is converted to other URL , this might be the reason for your problem as the $_GET['lang'] will not be exist on other converted URL.

Please check .htaccess file in your code directory.

There's a problem with the session handling You should start with session_start(); also you have to set the "lang" variable when you redirect ... Another option would be to include in the end of the url the ?lang= parameter (GET method)

echo '<meta http-equiv="refresh" content="0; url=/'.strtolower($idiomas[0]).'?lang='.$idiomas[0].'">';
