while 循环中的 PHP 输入-解网

问：

我想在 while 循环中根据数据库循环一组输入。但是我无法正确定义输入名称，当使用 var_dump（$_POST）检查时，提交的 POST 为空。

<body background="images/tl.jpg">
<div id="container">    
    <?php include "mysql/head.php" ?>
    <div id="main">



<p align="left"> Your Staff ID : <?php echo $_SESSION['u_username'] ?></p>
<p align="left"> Your E-Mail : <?php echo $_SESSION['u_acemail']; ?></p>

<form id="sub-form" action="mysql/save_result.php/">
    <center>
<table align="center" width=80% border="2" cellpadding="1" cellspacing="1">
<tr>
<th>Student Index No</th>
<th>Result</th>


    <?php

    include "mysql/dbconnect.php";

        $batchno = $_POST['batch'] ;
        $year = $_POST['y'];
        $semester = $_POST['s'];
        $tname = $batchno."_".$year."_".$semester;
        $subcode = $_POST['subject'];

        $_SESSION['batchno'] = $_POST['batch'];
        $_SESSION['year'] =  $_POST['y'];
        $_SESSION['semester'] = $_POST['s'];
        $_SESSION['tname'] = $batchno."_".$year."_".$semester;
        $_SESSION['subcode'] = $_POST['subject'];


    echo "Results Table Name : ".$tname;
    echo "<br><br>";
    echo "<b>Subject Code : ".$subcode."&emsp;&emsp;&emsp;Batch : ".$batchno."&emsp;&emsp;&emsp;Year : ".$year."&emsp;&emsp;&emsp;Semester : ".$semester."</b><br>";

        $sql = "SELECT stindex,id FROM $tname WHERE stindex NOT LIKE '%stindex%' ORDER BY id;";

        $result = mysqli_query($conn, $sql);
        $check = mysqli_num_rows($result);

        while ($row=mysqli_fetch_assoc($result)) {

                $resultid = "result_".$row['id'];

                echo "<tr><td align='center'>".$row['stindex']."</td><td align='center'><input type='text' name='$resultid'>".$resultid."</td></tr>";
            }

            echo "</table><br>";
            echo "<b>Number of Rows Fetched :  ".$check."</b><br><br>";
    ?>
