Displaying validation errors: PHP with MySQL Essential Training (2013)

For the best user experience, you should get into the habit of displaying validation errors in MySQL all at once. Let the errors accumulate, and require users to fix them before they can submit the form. A message at the end can request that users fix the following errors, such as not leaving a form blank, and tools such as a red border around fields with errors enables you to display them in a user-friendly way. This video tutorial also covers other issues with validation errors.
