Hello! Today we want to review the match_domain() function in the Requests_SSL class. This function is one of the key components in managing SSL connections in WordPress. If you also use WordPress, you must be familiar with secure connections and their importance. The goal of this function is to verify and match the domains with the provided SSL certificate.
First of all, it’s important to know that SSL (Secure Sockets Layer) helps us maintain a secure connection to websites. When you visit a website to perform sensitive operations such as purchasing, having SSL is essential. This function in WordPress ensures that the domain requested matches with the SSL domain certificate.
As an example, suppose you have a website and want to establish a connection with HTTPS; this is where this function comes into play. This function can check if the domains the user is trying to connect to match the existing SSL domain. If the domains match, it proceeds; if not, a secure connection will not be established, and the security of your site may come into question.
Perhaps currently, it may be useful to see how we can use this function in our code. We have a sample code for you showing how to utilize this function in practice.
Sample Code
$ssl = new Requests_SSL();
$is_match = $ssl->match_domain($requested_domain, $ssl_certificate_domain);
if ($is_match) {
echo 'The domains match!';
} else {
echo 'Warning: The domains do not match!';
}Code Explanation
Code:
$ssl = new Requests_SSL();This line creates an instance of the
Requests_SSL class.Code:
$is_match = $ssl->match_domain($requested_domain, $ssl_certificate_domain);Here, the
match_domain() function is called to check if the requested domain matches with the SSL certificate domain.Code:
if ($is_match) {...If the domains match, this block executes and prints a message indicating the domains match.
Code:
else {...}If the domains do not match, this block executes and issues a warning to the user.
