PHPExcel通过xls文件上传数据

你知道我做错了什么吗？我尝试做的是从选择框中选择一个值，然后在单击submit时上载一个xls文件，然后将其上载到MySQL。但当我点击提交时，我得到了无效的post请求

require '../PHPExcel/Classes/PHPExcel.php';
require_once '../PHPExcel/Classes/PHPExcel/IOFactory.php';
$proposal = "select * from proposal";
$rsExport = mysqli_query($DBCONN, $proposal) or die(mysql_error());
echo '<form id="proposal_form" method="post">';
echo "<select id='select_your_proposal' name = 'select_your_proposal'>";
echo "<option value=''>Select Your Proposal</option>";
while ($row = mysqli_fetch_array($rsExport)) {
    echo "<option value='" . $row['id'] . "'>" . $row['enterpriseid'] . " - " . $row['sitename'] . " - " . $row['presaleconsultant'] . " </option>";
}
echo "</select>";

<?php
if (isset($_POST['select_your_proposal'])) {
    $proposal2 = mysqli_query($DBCONN, "select * from proposal where id = '" . $_POST['select_your_proposal'] . "'");
    $row = $proposal2->fetch_assoc();
    $proposalid = $_POST['select_your_proposal'];
    unset($sessionid);
    $sessionid = uniqid();
    $user = CurrentUserName();
    $date = date('Y-m-d H:i:s');
    ini_set('display_errors', 1);

    // Check valid spreadsheet has been uploaded

1.）上载用户文件：




您需要以代码看起来像dis的形式定义操作

1.）上传用户文件：

或者使用一些javascript重定向页面
您可能最好将其标记为
php
，因为（从您收到的错误中）PHPExcel与此无关，它甚至没有到达代码的这一部分。但是，您的提交按钮不应该在表单中吗（除非您连接了一些js来处理提交）？
