Question

目前，$ row ['value']返回到pollUpdate.php中的值字段，该字段不可编辑。如何使该字段可编辑，并以dB为单位更新值字段。我试图将ID = $ row ['name']和value = $ row ['value']传递给updatedPoll.php。这些值虽未在网址中传递。

            <?php
            $connection = mysqli_connect("localhost", "root", "");
            mysqli_select_db($connection, "ukelection2015");
            $rs = mysqli_query($connection, "select * from poll");
            ?>
            <hr>
            <table border=1>
                <tr>
                    <th>Name</th>
                    <th>Value</th>

                while ($row = mysqli_fetch_array($rs)) {
                    print("<form method= 'post' action= ''>");
                    for ($x = 0; $x <= 2; $x++) {
