Question

我正在尝试使用Dompdf创建PDF，在我的程序中，我根据表单中的输入使用动态参数进行模型查询，但是当我单击我的按钮将值从选择按钮发送到控制器时，数据没有正确发送，任何想法为什么？下面是我的代码

<form class="form" method="get" action="<?=site_url()?>/laporan/pdfdownload" id="myID" name="myName">
    <select id="sel1" class="form-control">
         <option disabled selected="selected">Pilih</option>
                  <?php foreach ($kerja as $rows){?>
                  <option value="<?php echo $rows->id_project?>"><?php echo $rows->id_project.' - '.$rows->nama_project ?></option>
                  <?php }?>
    </select>
    <select id="sel2" class="form-control">
         <option disabled selected="selected">Pilih</option>
                  <?php foreach ($item as $rows){?>
                  <option value="<?php echo $rows->id_project?>"><?php echo $rows->id_project.' - '.$rows->nama_project ?></option>
                  <?php }?>
    </select>
   <button id="filter_button" style="margin-top: 26px;margin-left: 28px;width: auto" name="filter_button" type="submit" class="form btn btn-danger"><i class="fa fa-search"></i>&nbspSearch</button>
</form>

这是我的控制器

public function pdfdownload(){
                                      //If i click submit then all of the post didnt get sended
    $one = $this->input->post('sel1');//no value at all, anyone know why?
    $two = $this->input->post('sel2');//no value at all, anyone know why?

    $data['real'] = $this->report_m($one,$two)->row();

    htmlcontent = $this->load->view('laporan/download/laporan3.php',$data,true);
    include(APPPATH."third_party/dompdf/autoload.inc.php");
    // require_once APPPATH . 'third_party/dompdf/autoload.inc.php';
    $dompdf = new Dompdf\Dompdf();
    $dompdf->load_html($htmlcontent);
    $dompdf->set_paper("f4");
    $dompdf->render();
    $dompdf->stream("cobadlu.pdf",array("Attachment" => false));
    exit(0);
}

Answer 1

在HTML表单中，您需要使用name属性，而不仅仅是ID：

<select id="sel2" name="sel2" class="form-control">

Answer 2

首先，您的表单中存在错误：

<form class="form" method="get" action="<?=site_url()?>/laporan/pdfdownload" id="myID" name="myName">

您在此处提供 method ='get'，请将其更改为'post'。

其次，您没有在输入类型中包含'name'属性，因此在提交后不会发送任何数据。所以添加名称属性：

<select id="sel1" name="sel1" class="form-control">
<select id="sel2" name="sel2" class="form-control">

dompdf表单提交没有发送数据codeigniter
