Form validation is a crucial aspect of web development that ensures the data submitted by users through forms on a website is accurate, complete, and secure. By implementing validation rules, such as required fields, email formats, password strength, and more, developers can prevent erroneous or malicious data from being submitted. This helps improve the user experience by guiding users to provide the correct information and reduces the risk of security vulnerabilities. In WordPress websites, form validation can be achieved using various methods, including client-side validation with JavaScript and server-side validation with PHP. Proper form validation is essential for maintaining data integrity and protecting websites from potential threats.
