PHP：一个查询中有两个表

我有两个不同的问题如下

这是我的网络和构建名称的列表

Network            BuildingName
Mass and Mobile    Araneta
Mass and Mobile    Home Sweet
Hotels             Atrium Hotels

例如： 在我的组合框中，将显示的网络有

“Mass and Mobile”和“Hotels”

，之后当我选择

Mass and Mobile

时，它将显示带有复选框的

“Araneta”

和

“Home Sweet”

。这是我的节目

 echo "<div><input type='checkbox' class='checkall'> Check all</div>";
    $section = mysql_query("SELECT fldBldgName FROM tblbuilding where fldNetname = '$get_ID' ORDER BY fldBldgName");
    while ($row = mysql_fetch_array($section))
    {
        echo "<tr><td>";
        echo "<div><input id='playbldg' type='checkbox'  name='play[]' class='chk_boxes1' value='" . $row['fldBldgName']."'>";
        echo $row['fldBldgName'];"</div>";
        echo "</td></tr><br/>";
    }
    echo "<br/>";
    echo "<br/>";
    echo "<input type='submit' name='save' value='Add'  onClick='checkFields()'>";

在Mass and Mobile中，最长总持续时间为08:00:00，我们可以看到Araneta大楼已经满了，但Home Sweet还没有满

我计划做的是，如果Araneta的建筑名称已满，则没有复选框，但当小于08:00:00时，复选框将出现

我要执行的示例输出：

阿拉内塔-08:00:00

甜蜜家园-00:25:00

输出：

假设“[]”是复选框

   Araneta
[] Home Sweet
[] Sugar Free
[] Google

我该如何实现呢？

希望这对你有用

    echo "<div><input type='checkbox' class='checkall'> Check all</div>";
    $section = mysql_query("SELECT fldBldgName,if(fldTotalDuration<'08:00:00','show','notshow') as status FROM tblbuilding where fldNetname = '$get_ID' ORDER BY fldBldgName");
    while ($row = mysql_fetch_array($section))
    {
        echo "<tr><td>";
        if($row['status']=='show'){
            echo "<div><input id='playbldg' type='checkbox'  name='play[]' class='chk_boxes1' value='" . $row['fldBldgName']."'>";
        }
        else{
            echo "<div>";
        }       
        echo $row['fldBldgName'];"</div>";
        echo "</td></tr><br/>";
    }
    echo "<br/>";
    echo "<br/>";
    echo "<input type='submit' name='save' value='Add'  onClick='checkFields()'>";

echo“全部检查”；
$section=mysql\u查询（“如果需要，请选择fldBldgName(fldTotalDuration@SwapnilPatil...Hi，很抱歉回复太晚。。感谢您对我及其作品的帮助！：）
    echo "<div><input type='checkbox' class='checkall'> Check all</div>";

        }
        else{
            echo "<div>";
