아제가 php 문이랑 html 문이랑 좀 착각을해서 다시 소스를 공유드려볼께요.

지금 여기에는 첨부파일 코드는 삽입되어있지 않은데, php에 삽입하려고하면 어떻게 넣어야할지 해서요 ㅠ

php

<meta charset="utf-8">
<?php

	$email_to = "*** 개인정보보호를 위한 이메일주소 노출방지 ***";
	$email_subject = "제목";
	$email_subject = '=?UTF-8?B?'.base64_encode($email_subject).'?=';

     
     
    function died($error) {
        // your error code can go here
        echo "<script> alert('메일발송을 실패하였습니다. 항목을 다시한번확인해 주세요.');";
		echo "history.go(-1);";
		echo "</script>";
        die();
    }
    // validation expected data exists
    if(!isset($_POST["catego"]) ||
        !isset($_POST['com_name']) ||
        !isset($_POST['email']) ||
       !isset($_POST['address']) ||

        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }
     

    $catego = implode(" / ",$_POST["catego"]);
    //$sangpum = $_POST['sangpum'];
    $com_name = $_POST['com_name']; // required

    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {

  }
