HTML PHP Form Upload .doc and .docx only
I need some help with my syntax. I need the possibility to upload either .doc or .docx files. But I dont know how to go about it. Please see my code:

    //Сheck that we have a file
	if((!empty($_FILES["datafile"])) && ($_FILES['datafile']['error'] == 0)) {
	  //Check if the file is JPEG image and it's size is less than 2mb
	  $filename = basename($_FILES['datafile']['name']);
	  $ext = substr($filename, strrpos($filename, '.') + 1);
	  if (($ext == "docx,doc") && ($_FILES["datafile"]["type"] == "application/vnd.openxmlformats-officedocument.wordprocessingml.document") && 
		($_FILES["datafile"]["size"] < 2100000)) {
		//Determine the path to which we want to save this file
		  $newname = dirname(__FILE__).'/upload/'.$filename;
		  //Check if the file with the same name is already exists on the server
		  if (!file_exists($newname)) {
			//Attempt to move the uploaded file to it's new place
			if ((move_uploaded_file($_FILES['datafile']['tmp_name'],$newname))) {
			   $sasquach = "The file has been saved as: ".$newname;
       		   $link= 'http://orchardsystems2012.co.za/'.$_SERVER['PATH_INFO'].'/upload/'.$filename;
			} else {
			   //echo "Error: A problem occurred during file upload!";
			}
		  } else {
			 //echo "Error: File ".$_FILES["datafile"]["name"]." already exists";
		  }
	  } else {
		 //echo "Error: Only .jpg images under 2mb are accepted for upload";
	  }
	} else {
	 //echo "Error: No file uploaded";
	}


Please help :)
