当 url 有变量时 $_GET 为空

2022-01-04 00:00:00 variables global-variables post get php

我有一个看起来像这样的网址 reg.php?lang=no_NO&passkey=test 我正在尝试获取密码变量，但它一直显示为空白.

I have a url that look like this reg.php?lang=no_NO&passkey=testand im trying to get the passkey variable, but it keeps showing up blank.

当我尝试 print_r($_GET); 它打印 Array ( ) ?！怎么会这样?

When I try print_r($_GET); it prints Array ( ) ?! How can this happen?

网站看起来像这样

    <?php

        print_r($_GET); 

        include('..libsSmarty.class.php');
    ?>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Activate account</title>

(...html code.. )

$smarty = new Smarty;

//$smarty->force_compile = true;
$smarty->debugging = false;
$smarty->caching = false;
$smarty->cache_lifetime = 120;


// PHP gettext api
define('PROJECT_DIR', realpath('./'));

(... define gettext ... )

$passkey=$_GET['passkey'];

(...work with passkey ...)

$smarty->display('templatessite.tpl');

?>


</body>
</html>

就是这样.我不明白为什么 $_GET 显示为空白.它已经让我发疯了一段时间了..

thats it. I can't understand why $_GET shows up blank. It's been driving me crazy for a while now..

推荐答案

当我遇到这样的问题时，我总是将我的脚本归结为基础.在脚本的最顶部试试这个:

When I run into something that stumps me like this, I always take my script right down to basics. Try this at the very top of your script:

var_dump($_GET);
exit;

然后您可以查看它是否实际上是从钩子中获取变量.如果没有，那么可能有更深层次的东西……比如 PHP 真的与 Apache 一起运行吗?如果它有效，开始添加其他东西，直到它再次停止，你就可以开始缩小罪魁祸首的范围.

Then you can see if in fact it is getting the vars from the hook. If not, then there may be something deeper... like is PHP really running with Apache? If it works, start adding in other things until it stops again and you can start narrowing down the culprit.
