KEEP FOR LATER USE!
$error = $this->handleFileUpload($importFile, $importFile['name']);

function handleFileUpload($fileData, $fileName)

	$error = false;

	$typeArr = explode('/', $fileData['type']); 

	print_r($typeArr);
	//If size is provided for validation check with that size. Else compare the size with INI file 
	if (($this->validateFile['size'] && $fileData['size'] > $this->validateFile['size']) || $fileData['error'] == UPLOAD_ERR_INI_SIZE) 
	{ 
		$error = 'File is too large to upload'; 
	} 
	elseif ($this->validateFile['type'] && (strpos($this->validateFile['type'], strtolower($typeArr[1])) === false))
	{ 
		//File type is not the one we are going to accept. Error!! 
		$error = 'Invalid file type'; 
	} 
		else 
	{ 
		//Data looks OK at this stage. Let's proceed. 
		if ($fileData['error'] == UPLOAD_ERR_OK) 
		{ 
			//Oops!! File size is zero. Error! 
			if ($fileData['size'] == 0)

				$error = 'Zero size file found.'; 
			} 
			else

				{ 
					//Finally we can upload file now. Let's do it and return without errors if success in moving.
