如何使用链接自动填充信息？

Question

I am trying to make a php file that can be run when someone puts anything into a certain url. Say I want to go to a php script with $name as "david". Is it possible to go to a url www.-.com/Join/david and have it not go to that url, but rather a php script with a variable set to david?

Answer 1

You can have a page called join.php that takes a querystring, like join.php?name=david

With some rules in your .htaccess file, you could then use the url /join/david/ to actually serve your join.php?name=david to the visitor.

The rules for this would be as follows:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/?join/(.*?)/?$ /join.php?name=$1 [L]

Additionally, you could add the following so that if anyone actually tries to go to join.php?name=david, they are redirected to the clean URL instead:

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /join\.php\?name=([^\&\ ]+)
RewriteRule ^/?join\.php$ /join/%1? [L,R=301]

This answer references a previous answer by Jon Lin to a very similar question.
