Dave,

 

I suggest you try a simple with <input type='file' name='file1' /> , and check how large the file could be uploaded.

 

check @$_FILES["file1"]["name"] and @$_FILES["file1"]["tmp_name"]

 

"name" mean the file name ,

 

and "tmp_name" mean the temp file path on the server.

 

Regards,
Terry
