12. Form Validation CodeIgniter Validation is an important process while building web application. It ensures that the data that we are getting is proper and valid to store or process. CodeIgniter has made this task very easy. Let us understand this process with a simple example. Example Create a view file myform.php and save the below code it in application/views/myform.php. This page will display form where user can submit his name and we will validate this page to ensure that it should not be empty while submitting. My Form Name Create a view file formsuccess.php and save it in application/views/formsuccess.php. This page will be displayed if the form is validated successfully. 49
CodeIgniter My Form Your form was successfully submitted! Create a controller file Form.php and save it in application/controller/Form.php. This form will either, show errors if it is not validated properly or redirected to formsuccess.php page.
