Before I used OOP if for example i had a form which the user had tried to submit but my php code had say seen that they have not entered a field, i could just echo something out next to the input box when the page reloads. But in OOP i cant see how to do it. During the validation from onside the class i can find errors and asign them to a variable or an array, but then how do i then show these errors to the user and echo out statements?
