MySQLI的问题

Question

我可能太累了，看了一个小错误，但是这段代码不会在我的数据库中输入任何信息。

$sql = "INSERT INTO TABLE_NAME (UPC, Description, Make, Model, SNLocation, IMEI_MEID, Resetting, Notes, Image)

VALUES ($UPC, $Desc, $Make, $Model, $SNLocation, $IMEI_MEID, $Resetting, $Notes, $Image)";

mysqli_query($con, $sql) or die(mysqli_error($sql));

有人可以帮我检查一下这是否存在语法问题？

Answer 1

因为你有错误

$sql = "INSERT INTO TABLE_NAME (UPC, Description, Make, Model, SNLocation, IMEI_MEID, Resetting, Notes, Image)  

VALUES ('$UPC', '$Desc', '$Make', '$Model', '$SNLocation', '$IMEI_MEID', '$Resetting', '$Notes', '$Image')";

从Notes, Image)] <-----移除] ，并且需要引用值

Answer 2

您需要删除]并用单引号（'）括起字符串值：

$sql = "INSERT INTO TABLE_NAME
       (UPC, Description, Make, Model, 
       SNLocation, IMEI_MEID, Resetting, Notes, Image)] <-- Here --> 

VALUES ($UPC, $Desc, $Make, $Model, $SNLocation, $IMEI_MEID, $Resetting, $Notes, $Image)";

mysqli_query($con, $sql) or die(mysqli_error($sql));
