HiddenField发布没有名称的值

Question

这很奇怪，我以前从未见过这个。我使用post将值发布回同一页面进行处理。一切正常，直到我尝试使用隐藏字段发布值。使用相同的惯例我以前使用了一百万次。奇怪的是，它没有使用提供的名称发布，它只是使用hiddenField作为名称。这是代码

<input name="eid" type="hidden" id="eid" value="<? print $_GET['eid']; ?>" />

我用它来解决这个问题

print_r($_POST);

这是结果

  

[hiddenField] =＆gt; 6

现在，它发布了值，并在发布之前发布了隐藏字段中的正确值，但由于某些原因我似乎无法弄清楚，它不使用我在HTML中设置的name属性识别它。我所有的其他值都在使用已发布的名称。任何见解都会受到高度赞赏，因为我不希望以后再处理一些尴尬的隐藏字段。

编辑：这是页面的其余代码（相关部分）

 <?
    if (isset($_POST['Submit']))
    {
        print "<p>EID: " . $_POST['hiddenField'] . "</p>";
        $eid = $_POST['hiddenField'];
        $name = $_POST['name'];
        $email = $_POST['email'];
        $ncount = count($name);
        $ecount = count($email);
        $hash = uniqid() . "-" . count($name);
        if ($ncount == $ecount)
        {
            $test = true;
            for ($i = 0; $i < $ncount; $i++)
            {
                if ($name[$i] == "" || $email[$i] == "")
                {
                    $test = false;
                }
            }

            if ($test)
            {
                $tickets[] = array();
                for ($i = 0; $i< $ncount; $i++)

                    while (!$unique)
                    {
                        $tickets[$i] = generateCode();
                        $check_query = "SELECT id FROM ticket WHERE ticket_number='" . $tickets[$i] . "'";
