File Upload

[eluser]Unknown[/eluser]
Hello, Im currently doing a project that uses the file image class. I currently display a form with inputs and a file input. Now the user should not have to upload a given file when they edit this form all the time. Im wondering how to check to see if the user has submited a file and then check if file upload is sucessful and then process it?

If your form input for the file was:

Code:

<input type="file" name="file"  />

Then you could do this

Code:

if($_FILES['file']['size'])
        {
            // do upload here
        }
