我正在为教师创建一个组件，教师可以为所有完成课程的学生生成pdf。 应该生成检查所有学生和pdf并将其保存在磁盘上。之后提供下载链接以下载生成的所有pdfs的zip。这就是我想要实现的目标。我使用fpdf生成pdf。 有什么建议吗？
以下是发布的表单和学生ID
<form
action="<?php echo JRoute::_('index.php?option=com_mentor&view=download_certificate&cid=' . $cid . '&Itemid=529') ?>"
name="download_certificate" method="post" id="download_certificate">
<table class="adminlist" border="1" cellpadding="0" cellspacing="0"
style="table-layout: fixed" id="content">
<thead>
<tr>
<th class="nowrap" style="width: 35px">
<input type="checkbox" name="selectall" id="selectall">
</th>
<th class="nowrap" align="center">
<?php echo JText::_('COM_MENTOR_USER_NAME'); ?>

<th class="nowrap" style="width: 140px">

<script>
function checked_value() {
var checkedValue = [];
var $len = $(".checkbox1:checked").length;
if ($len == 0) {
alert('Please select user');
}

var $this = $(this);
if ($this.is(":checked")) {
checkedValue.push($this.attr("id"));
}
});
$("#download_certificate").submit();
</script>
在点击图片标签上，表单会与学生ID一起提交，我会收到学生数据，他的姓名，成绩，课程，
<img src="/components/com_mentor/images/certificate_blue.png" class="certificate-ico right"
title="Download Certificate" onclick="checked_value();"/>
完成此处理后，页面将重定向到pdf.php页面
require_once('/wamp/opt/bitnami/apache2/htdocs/lms/lib/fpdf/fpdf.php');
$pdf = new FPDF(); $pdf->SetFont('times', '', 12);
$pdf->SetTextColor(50, 60, 100); $pdf->AddPage('L');
$pdf->SetDisplayMode(real, 'default'); $pdf->SetXY(10, 60);
$pdf->SetFontSize(12);
$pdf->Write(5, 'Dear Ms.XYX');
$filename = "test.pdf";
$dir = "/assets/";
$pdf->Output($dir . $filename, 'F');
