File upload with form data functionality is very useful for the web form. If you want to allow the user to send an attachment with the web form, file upload functionality needs to be integrated. The form submission and file upload functionality can be implemented easily with PHP.
Alternatively, you can build webform with file upload functionality without page refresh using jQuery and Ajax. JavaScript FormData interface provides an easy way to send form fields and their values to the server-side via Ajax. With the FormData object, the web form submission and file upload functionality can be implemented without page refresh.
In this tutorial, we will show you how to upload multiple files with form data using jQuery, Ajax, and PHP. You may also be running into an issue where the values are being repopulated by the struts value stack. In other words, you submit your form, do whatever in the action class, but do not clear the related field values in the action class.
In this scenario the form would appear to maintain the values you previously submitted. If you are persisting these in some way, just null each field value in your action class after persisting and prior to returning SUCCESS.
