If you’re a WordPress developer that writes HTML/CSS/JS, you should be very alert about website security. As it is one of the important aspects to protect your website from hackers, spammers etc. You need to prevent them from injecting malicious code into your databases. You must have heard about escaping. It helps to secure your data prior to rendering it for an end user. It also prevents cross-site scripting (XSS). WordPress provides built-in functions to stop this type of things automatically. But if you need to escape your output in a specific way, wp_kses function in WordPress will come handy. It will give you control over what is allowed and what’s not.
