Question

这是我的第一篇文章。请温柔。

我正在为设备服务历史创建一个基本数据库。我最初使用MySQL。但是，在阅读了很多帖子后，我试图改成mysqli。我页面中的前两个数据库连接正常工作。但第三个是在我的服务历史部分发布“0000-00-00 $ tech $ history”。当我使用MySQL vs mysqli时，一切正常。我确定我错过了一些简单的事情。我搜索过谷歌，找不到任何解决此问题的方法。

这是给我提问的页面的php部分。提前谢谢。

//This section sends service data to the specified database//
$con = mysqli_connect("localhost","root","pass","bed_logs");

// Check connection
if (mysqli_connect_errno())
{
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

if(isset($_POST['add']))
   if(! get_magic_quotes_gpc() )
   {
       $history = addslashes ($_POST['history']);
       $service_date = addslashes ($_POST['service_date']);
       $tech = addslashes ($_POST['tech']);

   }
   else
   {
       $tag5156 = $_POST['history']['tech']['service_date'];
   }
$sql = 'INSERT INTO tag5156 (service_date,tech,history) VALUES ("$service_date","$tech","$history")';

while ($row = mysqli_fetch_assoc($retval))
{
    print_r ($row);
}
$retval = mysqli_query($con,$sql);

if(! $retval )
{
    die('Could not enter data: ' . mysqli_error($con));
}
{
    echo "<CENTER>Record Updated</CENTER><BR><BR>";
}
mysqli_close($con);

HTML似乎运行良好。

Answer 1

这一行：

$sql = 'INSERT INTO tag5156 (service_date,tech,history) VALUES ("$service_date","$tech","$history")';

应该是

$sql = "INSERT INTO tag5156 (service_date,tech,history) VALUES ('$service_date','$tech','$history')";

或

$sql = 'INSERT INTO tag5156 (service_date,tech,history) VALUES ("'.$service_date.'","'.$tech.'","'.$history.'")';
