Message:

I have a registration and activation code that I am updating a bit, after the user registers it sends them a email to activate.

Link emailed

/user/activate/$hashed_confirm_code

which generates

http://example.com/user/activate/0dbc0aef3d4d9d3e67ee4bf6c

I went to http://www.visiospark.com/mod-rewrite-rule-generator/ and did a mod rewrite changed the email link accordingly.

rewrite is on

RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]

RewriteRule ^ /%1 [NC,L,R]



RewriteCond %{REQUEST_FILENAME}.php -f

RewriteRule ^ %{REQUEST_URI}.php [NC,L]



RewriteCond %{QUERY_STRING} (^|&)hash_token=($|&)

RewriteRule ^user/activate$ /user/activate/?&%{QUERY_STRING}

if i click the link it produces the following in the browser

http://example.com/user/activate/0dbc0aef3d4d9d3e67ee4bf6c

however it just gives a 500 error, the basics of my activation code function is

function activate_user(){



    if (($_SERVER['REQUEST_METHOD'] === "GET") && isset($_SERVER['QUERY_STRING'])) {



        $confirm_code = $_SERVER['QUERY_STRING'];



       //do stuff





    }

}

now if i change the link in the browser

example.com/user/activate/0dbc0aef3d4d9d3e67ee4bf6c93c

to this

example.com/user/activate?0dbc0aef3d4d9d3e67ee4bf6c

it works, so if i remove the forward slash and add the question mark it works

My Answer:
To retrieve the parameter without the parameter name in PHP, you can use the $_SERVER['REQUEST_URI'] variable and then parse the URL to extract the parameter value. Here is an example code snippet to achieve this:

php
// Get the current request URI
$request_uri = $_SERVER['REQUEST_URI'];

// Extract the parameter value from the URI
$parts = explode('/', $request_uri);
$hashed_confirm_code = end($parts);

// Use the $hashed_confirm_code variable in your code
echo "Hashed Confirm Code: " . $hashed_confirm_code;


In this code snippet, we first get the current request URI using $_SERVER['REQUEST_URI']. Then, we split the URI by '/' and extract the last part, which is the parameter value we are interested in. Finally, we store this value in the $hashed_confirm_code variable for further use in your code.
