Extract text from URL using javascript and display on php file

Question

I have an error message on the URL when wrong password or captcha is added. Error looks like this on the url:

www.domain.com/signup.php?error_msg=The+characters+you+entered+did+not+match+the+word+verification

How to extract this from URL and display on the PHP file?

Answer 1

Just use the global $_GET array to retrieve the value:

echo $_GET['error_msg'];

More about this array can be found in the official documentation: http://php.net/manual/en/reserved.variables.get.php
