Data validation

**Data Validation**

Data validation is a crucial process in ensuring the accuracy, quality, and integrity of data entered into a system or application. It involves verifying that the data meets predefined rules and criteria before it is processed or stored. In the context of web development and WordPress, data validation helps prevent errors, security vulnerabilities, and inconsistencies by checking user input, form submissions, and database entries. Proper data validation improves overall user experience and maintains the reliability of your website’s data.
