    echo "<script>alert('You have successfully Updated Email') </script>";
    }
    else 
     echo "<script>alert('You have Enter Wrong Password') </script>";
}
 ?>

我的查询结果更新寄存器集name ='m'，f_name ='dsf'，l_name ='dfsf'，sellers ='消费者'，company =' fdafa'WHERI id ='3

在sql中执行此查询时，它工作正常，但在我的php文件中，它在“字段列表”中给出了错误未知列'name'。我已经检查了我的专栏名称是否正确。同时我更改代码放置然后错误是相同的但列名称改变了 “字段列表”中的未知列'f_name'。其次，我的其他人查询成功执行但不影响我的数据库。这些查询在mysql中运行正常。

也许您在PHP中使用了错误的表/数据库？

echo "<pre>", var_dump( mysql_fetch_assoc( mysql_query("SHOW TABLES") ) ) , "</pre>"

表格在输出中吗？如果是，那么下一个输出中的列是什么？

echo "<pre>", var_dump( mysql_fetch_assoc( mysql_query("SHOW COLUMNS FROM register") ) ) , "</pre>"

未知列＆＃39;名称＆＃39;在＆＃39;字段列表＆＃39;
