联系表单中的多个文件附件7

Question

当我将表单结果从联系表单7导出为PDF（fPDF）时。然后我们的联系表格7文件上传没有显示在联系表格7消息正文中。意味着两个附件文件都没有正确显示如何解决这个问题。我正在使用我的代码创建一个pdf，然后将其附加到我的电子邮件，工作正常，但当我从联系表单7前端上传文件然后我们的PDF文件没有显示。我的代码是：

add_filter( 'wpcf7_mail_components', 'mycustom_wpcf7_mail_components' );
function mycustom_wpcf7_mail_components($components){

if (!empty($components['attachments'])) {
//$components['attachments'] = array( 'attachedfile' =>  FPDF_PATH.'/dompdf-master/'.'Shoop.pdf'); // ATTACH THE NEW PDF THAT WAS SAVED ABOVE
$components['attachments'] .= array(FPDF_PATH .'/dompdf-master/'.'Shoop.pdf'); // ATTACH THE NEW PDF THAT WAS SAVED ABOVE
}
return $components;
}

Answer 1

转换：

$components['attachments'] .= array(FPDF_PATH .'/dompdf-master/'.'Shoop.pdf');

要：

$components['attachments'][] = FPDF_PATH .'/dompdf-master/'.'Shoop.pdf';
