Question

你知道我在做错了什么吗？我尝试做的是从选择框中选择一个值，然后在我点击提交时上传一个xls文件，然后将其上传到MySQL。但是当我点击提交时，我收到了无效的帖子请求。

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>";

您需要在代码看起来像dis的形式中定义操作 <form method="post" enctype="multipart/form-data" action="yournextpage.php"> 1.) Upload User File: <input type="file" name="spreadsheet"/>

或者使用一些javascript来重定向页面
