[英]php redirect based on url variable
I want to create a URL redirect based on a URL variable. 我想基于URL变量创建URL重定向。
so, if student%20gender (student gender) is male then go to www.one.com, if female, go to www.two.com. 因此,如果Student%20gender(学生性别)是男性,请访问www.one.com,如果是女性,请访问www.two.com。
couldn't figure this one out yet. 还不知道这个。 any help? 有什么帮助吗?
Question could use a little bit of a better explanation. 问题可以使用更好的解释。 Do you mean that someone is going to http://www.yoursite.com/yourscript.php?student%20gender=male
and you want them to be redirected to http://www.one.com
? 您是说有人要访问http://www.yoursite.com/yourscript.php?student%20gender=male
并且您希望他们重定向到http://www.one.com
吗?
If this is the case, PHP has a built in variable known as $_GET
which stores the values listed after a ?
在这种情况下,PHP具有一个内置变量$_GET
,该变量存储在?
之后列出的值?
in a URL. 在网址中。 So in the above example, we'd see: 因此,在上面的示例中,我们将看到:
$_GET['student gender'] = male;
You can use this to access any number of parameters separated by &
您可以使用它来访问由&
分隔的任意数量的参数
So the URL http://www.site.com/index.php?val1=a&val2=b&val3=c
would give us: 因此,URL http://www.site.com/index.php?val1=a&val2=b&val3=c
将为我们提供:
$_GET['val1'] = a;
$_GET['val2'] = b;
$_GET['val3'] = c;
After this, to do a redirect in PHP the easiest way is to send a Location:
header. 此后,要在PHP中进行重定向,最简单的方法是发送Location:
标头。 This is done like so: 这样做是这样的:
<?php
header("Location: www.newsite.com");
?>
Combining this with our $_GET
variable and some simple logic: 结合我们的$_GET
变量和一些简单的逻辑:
<?php
if($_GET['student gender'] == 'male'){
header("Location: www.one.com");
die();
} else {
header("Location: www.two.com");
die();
}
?>
$var = $_GET['yourvar'];
if($var == 'one'){
header("Location: http://www.one.com/");
}else if ($var == 'two'){
header("Location: http://www.two.com/");
}
then do http://www.yoururl.com?yourvar=one 然后执行http://www.yoururl.com?yourvar=one
You also have to make sure you look at the security aspects here, the best way yo accomplish this is 您还必须确保在此处了解安全方面,实现此目标的最佳方法是
$gender = isset($_REQUEST['gender']) ? $_REQUEST['gender'] : false;
switch($gender)
{
default: //The default action
//Send back to the gender select form
break;
case 'male':
//Send to male site!
break;
case 'female':
//Send to female site!
break;
}
This should be sufficient, but please never use $_X['?']
in functions that execute either shell or database queries without sanitation. 这应该足够了,但是请不要在无条件地执行shell或数据库查询的函数中使用$_X['?']
。
Note: _X
being (GET,POST,REQUEST,FILES) 注意: _X
为(GET,POST,REQUEST,FILES)
