Im putting together a drag and drop page where a user will drag an ellement (in this case and printable pdf) over into a print field.
I need blank fields on the right to return either as (void skip this) or with default pdf.
Here is the page Click Here
I answered my own questin incase someone needs to know. When validating the form I used
if( $item == "")
If that doesnt make sense feel free to message me and I can help explain.
