当url有变量时，$ _GET为空 [英] $_GET is empty when the url has variables
问题描述
我有一个类似于 reg.php？lang = no_NO& passkey = test 的网址，我试图获取密码变量，但它一直显示为空白。
当我尝试 print_r（$ _ GET）; 时，它会打印 Array（） code>？！这是怎么发生的？
这个网站看起来像这样
<？php
print_r（$ _ GET）;
包含（'.. \libs\Smarty.class.php'）;
？>

（... 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'];
（...使用密钥...）
$ smarty-> display（'templates \site.tpl'）;
？>
< / body>
< / html>
就是这样。我不明白为什么$ _GET显示空白。这让我发疯了一阵子。
当我遇到像这样困扰我的东西时，我的脚本直到基本。在脚本的最上面试试这个：
var_dump（$ _ GET）;
出口;
然后您就可以看到实际上它是否从钩子中获得了变量。如果没有，那么可能会有更深层次的东西......就像PHP真的在Apache上运行一样？如果它起作用，开始添加其他东西，直到它再次停止，你可以开始缩小罪魁祸首。
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.
When I try print_r($_GET); it prints Array ( ) ?! How can this happen?
The site look something like this
<?php
print_r($_GET);
include('..\libs\Smarty.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('templates\site.tpl');
?>
</body>
</html>
thats it. I can't understand why $_GET shows up blank. It's been driving me crazy for a while now..
When I run into something that stumps me like this, I always take my script right down to basics. Try this at the very top of your script:
var_dump($_GET);
exit;
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.
