If you’ve worked with submitting form data in WordPress you may have run into issues with quotes being slashed.
WordPress automatically escapes single and double quotes from any user input data as a security measure.
Let’s say a user enters their name as “Mike O’Reilly”. If you were to access that data directly with
$_POST['name'] it would output “Mike O\’Reilly”.
WordPress provides the
wp_unslash function to remove those slashes for use in your code. Using
wp_unslash( $_POST['name'] ); would output “Mike O’Reilly”.
If you setup your editor to follow the WordPress Coding Standards, you’ll see that it reminds you to use
wp_unslash anytime you’re accessing
$_POST data among other user input data.

The Authentik community from Brian Gardner and co. just launched and seems like it could be a great learning experience. No affiliation on my end, just a lot of great people I’ve followed are part of this project.
