这是我将近一周的问题，我无法解决。

设想：

在我保存数据之前，会出现一条确认消息，说... Station is full. do you want to continue saving?...然后当我尝试取消它时，它仍在保存数据..

按取消按钮将不再保存....

假设我有一个建筑物名称：Star 1 和 Star 2 ......

" Star 1"和"Star 2"将是$bldg的值 ..那么 STAR 1的总持续时间是 08:00:00 [这已经满了]，那么STAR 2 的总持续时间是 00:00:00 [数据库中尚不存在]

这是我的代码：

if (isset($_GET['js_varOK'])) 
$cancel = $_GET['js_varOK'];
else $cancel = "not";

    if($cancel != "yes")
    {
        for($i=0; $i<sizeof($bldg);$i++)
        {
        if($cancel != "yes")
        {   
        $result = mysql_query("SELECT * FROM tbldata WHERE  fldNetname = '".$network."' AND fldBldgName = '".$bldg[$i]."'  AND  fldWeek = '".$week."' AND fldMonth = '".$month."'  AND fldYear ='".$year."' ORDER BY id desc");
        if(mysql_num_rows($result)==0)
        {
        $totalduration = "";
        $seconds = 0;
        $minutes = 0;

        $computeSecMin = $seconds * $minutes; 
        $subSecMin = $computeSecMin + $duration; 
        $getMin = floor($subSecMin/60); 
        $getSec = $subSecMin%60; 
        $totalduration = $getMin .":". $getSec; 
        $query2 = "INSERT INTO tbldata(fldNetname,fldBldgName,fldPlaylist,fldMonth,fldWeek,fldYear,fldDuration,fldFrom,fldTo,fldTotalDuration,fldTimestamp,fldStatus, fldUser) VALUES ('".$network."','".$bldg[$i]."','".$AdName."','".$month."','".$week."','".$year."','".$duration."','".$from."','".$to."', '".$totalduration."','".$date."','".$status."',(SELECT fldid from tblmembers where fldUsername= '".$_SESSION['user']."'))";
        mysql_query($query2) or die (mysql_error());    

        echo "<script type='text/javascript'>\n";
        echo "alert('Data have been saved first!');\n";
        echo "</script>";       
        }
        else
        {
        while ($row = mysql_fetch_array($result))
        {
        if($network == "Mass and Mobile" && $row[fldTotalDuration]  == "08:00:00"  && $duration >= "0 s")
        {?><?php
        if(sizeof($bldg) == 1)
        {
        echo "<script type='text/javascript'>\n";
        echo "alert('$bldg[$i] station is already full.');\n";
        echo "window.location='booking_content.php'";
        echo "</script>";
        }
        else
        { ?>
        <script>
        var myVar = "station is already full. Do you want to save the other networks?";
        var js_varOK;
        var bldg;
        var network;
        if (confirm(myVar)) 
        {
        js_varOK = "no";
        bldg = "<?php echo $bldg?>";
        network= "<?php echo $network?>";
        window.location = "?js_varOK=" + js_varOK + "&bldg="+bldg + "&network="+network;
        } else 
        {
        js_varOK = "yes";
        window.location = "?js_varOK=" + js_varOK;

        }
        </script>
        <?php
        }

        }
        }

    }
    else
    {
       //do noothing
    }

因此，当我点击取消时，它只会转到else of do nothing...但它仍在保存..

根据我的理解... STAR 1 将是第一个读取 for 循环的程序，然后它会转到"if($network == "Mass and Mobile" && $row[fldTotalDuration] == "08:00:00" && $duration >= "0 s")"然后会出现一条弹出消息然后我将单击取消按钮然后值$cancel已经是“是”，那么 STAR 2 已经保存在我的数据库中，这应该是在单击取消时停止程序以保存它....

谢谢..

您的变量$_GET['js_varOK'] 在这两种情况下都已设置。如果您不想保存，它只是空的。

尝试像这样证明：

if (isset($_GET['js_varOK']) && $_GET['js_varOK'] != '') { // better way: .. && $_GET['js_varOK'] == 'yes'
    echo 'save';
} else {
    echo 'dont save';
}

我建议稍微清理一下您的代码。利用

if ($a == $b) {
    echo 'yes';
} else {
    echo 'no';
}

代替

if ($a == $b) echo 'yes';
else echo 'no';

它只是多一点代码，但不容易出错。
