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.
