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?

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

I solved it with this: I have no idea how to post code here... <br><br> <?php $url = 'https://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; if (strpos($url,'My+Error') !== false) { echo '<div class="error_message">' . $error_message . '</div>'; } else { echo '';} ?>

@LinasMaz You could have just checked if the value was set using the isset function like so: if (isset($_GET['error_msg'])) echo $_GET['error_msg'];
