Php插入查询和电子邮件附件

Question

希望有一些帮助，无法找到问题，我有一个脚本，基本上它是什么，提交候选人简历形式。

当用户填写表格并填写他的个人信息并附上他的简历时，表格会将信息和cv路径保存在数据库中并将cv保留在服务器内的文件夹中，而不是向公司发送电子邮件发布这份工作。一切正常，但只有一个问题，这就是简历，这不是将CV附加到发送给公司的电子邮件中。

有人可以查看代码吗？

if(isset($_FILES['files'])){


$errors= array();
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
    $file_name = $key.$_FILES['files']['name'][$key];
    $file_size =$_FILES['files']['size'][$key];
    $file_tmp =$_FILES['files']['tmp_name'][$key];
    $file_type=$_FILES['files']['type'][$key];  



    $random_digit=rand(0000,9999);

    $new_file_name=$random_digit.$file_name;

    if($file_size > 2097152){
        $errors[]='File size must be less than 2 MB';
    }       




    $query2="INSERT into candidates (`firstname`,`lastname`,`mobile`,`email`,`message`,`id_company`,`titulo_anuncio`,`job_type`,`data`,ativo) VALUES('$firstname','$lastname','$mobile','$email_candidate','$message','$id_company','$title_en','$job_type','$data','1'); ";
    mysql_query($query2);
    $user_id = mysql_insert_id();

    $query="INSERT into media (`id_candidate`,`file`,`size`,`type`) VALUES('$user_id','$new_file_name','$file_size','$file_type'); ";
    $to = $email;
    $subject = "Domainname.com | Portal of Jobs - New Candidate";

    $body = "";
    $body .= "Title Job: ";

    $body .= "\n";

    $body .= "In Attachement";
    $body .= "\n";



    $headers = "From:" . $to;
     if (mail($to, $subject, $body,$headers))


    $desired_dir="candidates_cv";
    if(empty($errors)==true){
        if(is_dir($desired_dir)==false){
            mkdir("$desired_dir", 0700);        // Create directory if it does not exist
        }
        if(is_dir("$desired_dir/".$new_file_name)==false){
            move_uploaded_file($file_tmp,"$desired_dir/".$new_file_name);
        }else{                                  // rename the file if another one exist
            $new_dir="$desired_dir/".$new_file_name.time();
             rename($file_tmp,$new_dir) ;               
        }

     mysql_query($query);           
    }else{
            print_r($errors);
    }
}
if(empty($error)){
    echo "<span style=\"color:green;font-weight:bold;\">Submitted whit Sucess Thanks</span>";
