Javascript 将细枝中的数组数据与symfony 3中的表单数据一起发布

我有一个web应用程序，它正在将用户电子邮件和名称从.csv文件导入数据库以进行邮件合并

上传后，我将.csv数据（作为一个数组）从控制器传递到要进行列匹配的细枝，以确保将正确的值持久化到数据库（firstname列实际上是firstname等）。用户通过列上方的choiceType下拉列表进行验证，并通过表单中内置的按钮提交他们的选择。然后由控制器执行此操作，并用于将正确的列数据持久化到数据库中。但是，由于.csv文件是在请求/响应周期后临时存储的，因此会被清除。因此，我想将我发送的要在细枝中显示的.csv数据发布回控制器，以便持久化到数据库中

这只能使用javascript来完成吗？或者在Symfony中有没有办法做到这一点

以下是细枝的相关部分：

        <div class="row">
        <div class="col-lg-12">                
            <section class="panel">
                <div class="panel-body">
                    <table class='table table-hover no-margin reports-table'>
                        <thead>
                            <tr>

                                   {{ form_start(emailCampaignListUserImportCheckForm)}}
                                   {{ form_row(emailCampaignListUserImportCheckForm.column1) }}
                                </th>

                                      {{ form_start(emailCampaignListUserImportCheckForm)}}

                                      <th>
                                        {{ form_start(emailCampaignListUserImportCheckForm)}}
                                        {{ form_row(emailCampaignListUserImportCheckForm.column3) }}

                                    </td>
                                </tr>                                     
                              {% endfor %}
                        </tbody>
                    </table>                          
                </div>   

以下是文件的上载方式：

 //  grab uploaded .csv file
    $file = $_FILES["file"]["tmp_name"];
    $fileimplode = implode("/", $file); 

    // convert .csv if made on mac
    if (!ini_get("auto_detect_line_endings")) {
        ini_set("auto_detect_line_endings", '1');
    }
    //  create array from .csv
    $reader = Reader::createFromPath($fileimplode);
    $addedUsers = $reader->fetchAll();
    $emailCampaignList = $this->get('email.list_repository')->find($request->get('listId'));

    return $this->render('EmailBundle:MailMerge:emailCampaignListsUsersImportCheck.html.twig',
    [
        'emailCampaignList' => $emailCampaignList,
        'addedUsers' => $addedUsers,
        'emailCampaignListUserImportCheckForm' => $emailCampaignListUserImportCheckForm->createView(),
        'listId' => $request->get('listId')
    ]                   
    );

您可以将数据放在隐藏字段中，以便将其传递到第二步。请原谅，这似乎很简单，因为我对这一点很陌生：我是否向表单中添加HiddenType字段，然后将传递的数组（$addedUsers）作为变量添加到细枝中的函数中？请说明如何在PHP中定义表单。添加到问题：文件是如何上载的？

 //  grab uploaded .csv file
    $file = $_FILES["file"]["tmp_name"];
    $fileimplode = implode("/", $file); 

    // convert .csv if made on mac
    if (!ini_get("auto_detect_line_endings")) {
        ini_set("auto_detect_line_endings", '1');
    }
    //  create array from .csv
    $reader = Reader::createFromPath($fileimplode);
    $addedUsers = $reader->fetchAll();
    $emailCampaignList = $this->get('email.list_repository')->find($request->get('listId'));

    return $this->render('EmailBundle:MailMerge:emailCampaignListsUsersImportCheck.html.twig',
    [
        'emailCampaignList' => $emailCampaignList,
        'addedUsers' => $addedUsers,
        'emailCampaignListUserImportCheckForm' => $emailCampaignListUserImportCheckForm->createView(),
        'listId' => $request->get('listId')
    ]                   
    );
