Question

我有3个表涉及此交易，项目，交易和销售。问题仅出现在销售表中，因为如果要插入到现场客户的值是数字，它只会保存到表销售中，但如果要插入的值是客户的名称则不保存。它似乎只接受数字，但我的客户数据类型是文本，它必须接受字符，如我们的名字。抱歉，我的英语不好，但我希望你能帮助我，代码和表格在下面

<?php

	include ('dbconnect.php');
	$itemcode = $_POST['itemcode'];
	$cusname = $_POST['cusname'];
	$price = $_POST['price'];
	$qty = $_POST['qty'];
	$left = $_POST['left'];	
	$newstock = ($left - $qty);
	$amount = $_POST['amount'];
	$tobepaid = ($price * $qty);
	$change = ($amount - $tobepaid);

	if ($amount<$tobepaid){
			echo "<script language='javascript'>
					alert('The amount tendered is insufecient for the item');
					document.location.href='stockout.php';
				</script>";	
	}
	else{
	mysql_query("update item set 
		qty = '$newstock'
		where itemcode = '$itemcode'");



    $result = mysql_query("INSERT INTO `transaction` (`transtype`, `itemcode`, `prevstock`, `qty1`, `currentstock`) VALUES ('stockout',$itemcode,$left,$qty,$newstock)");
	$result = mysql_query("INSERT INTO `sales` (`itemcode`,`customer`, `qty2`,`tobepaid`, `amount`,`change`) VALUES ($itemcode,$cusname,$qty,$tobepaid,$amount,$change);");


	echo "<script language='javascript'>
					alert('Updated $cusname');
					document.location.href='stockout.php';
				</script>";	
	mysql_close($con);
}
?>
