Change content based on many urls

[Wunderkid]

Hello!

I`m newbie and just started with php. Could you help me?

I want to change text based on many url.

I write code, but it filtering only one url

 

<?php
$ref=getenv('HTTP_REFERER');
if (strpos($ref,"www.site.com/news")>0)
{
echo "News;
}
else
{
echo "";
};
?>

 

I want to make something like that, but it is not working, maybe you can edit it make it work

 

<?php
$ref=getenv('HTTP_REFERER');
if (strpos($ref,"www.site.com/1")>0)
{
echo "1;
}
else
{
if (strpos($ref,"www.site.com/2")>0)
{
echo "2;
}
else
{
if (strpos($ref,"www.site.com/3")>0)
{
echo "3;
}
else
{
?>

I don't think you want to use HTTP_REFERER. For one, you're not guaranteed that it will have a value. Two, HTTP_REFERER refers to the previous site the user was on. So, if I came here from google, HTTP_REFERER (if it had a value) would be http://www.google.com.

 

If you're trying to do what I think you want, you instead need to use query strings. If you have a url like:

 

www.site.com/index.php?p=news

 

The part starting at the '?' is known as a query string. You can grab its value by using the $_GET[] superglobal array, like so:

 

$page = $_GET['p']; // $page now contains 'news'

 

Obviously, you'd need to ensure that:

 

1. 'p' exists

2. it doesn't contain bad/dangerous data

 

But that's the general idea.

 

To make that work with a 'pretty' url, like:

 

www.site.com/news

 

You'll need to write a .htaccess file with the appropriate mod_rewrite rule(s). I suck at writing those, so someone else can address that part of it.
