see is a FILES input was used

[jwk811]

there is a working file input in the form. when i process it EVEN if nothing was uploaded it still will say that the FILES input isset and != ''. how can i see if its actually being used?

Try putting this in your code. Replace "thefile" with the name of your file input element.

 

if(array_key_exists('thefile', $_FILES)) {
// Handle the uploaded file here
}

If a file is not selected, you will get an upload error value of 4.

 

I recommend examining and using some for the error checking logic in this post - http://www.phpfreaks.com/forums/index.php/topic,292945.msg1386624.html#msg1386624

if(isset($_FILES['myfile']) && $_FILES['myfile']['error'] != UPLOAD_ERR_NO_FILE)
{
// no file was uploaded, there could be a different error though
}
