Unable to read PHP Mail Attachment - php

Question

I am new to PHP, I need to create a form such that it asks the user to enter several fields and upload his/her resume. When he/she submits the form, his/her submissions should be email to me with his/her resume as the attachment with the email. I have used PHP for sending the email using php mail function. Everything works fine, except that the file attachment is not able to read. Please see the screenshot attached.

Also the file uploaded is in odt format. I need users to upload all type of resume formats.
I am posting the Essential Part of the Code. Please correct me if I am wrong
if ($_POST['submit_x']) {
$cand_name = trim($_POST['cand_name']);
$appl_email = $_POST['email'];
$target_dir = "/home/test/public_html/new/job/hr/Resume/";
$file = $_FILES['my_file']['name']; // Resume-Test.odt
$path = pathinfo($file);
$ext = $path['extension']; // odt
$temp_name = $_FILES['my_file']['tmp_name']; // /tmp/phpqkLeuL
$path_filename_ext = $target_dir.$file.".".$ext;
move_uploaded_file($temp_name,$path_filename_ext);
$mailto = 'robert.k1254#gmail.com';
$subject = 'Subject';
$message = 'My message';
$content = file_get_contents($path_filename_ext);
$content = chunk_split(base64_encode($content));
// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (RFC)
$eol = "\r\n";
// main header (multipart mandatory)
$headers = "From: name <test#test.com>" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol;
// message
$body = "--" . $separator . $eol;
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$body .= "Content-Transfer-Encoding: 8bit" . $eol;
$body .= $message . $eol;
// attachment
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $file . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol;
$body .= $content . $eol;
$body .= "--" . $separator . "--";
//SEND Mail
if (mail($mailto, $subject, $body, $headers)) {
echo "mail send ... OK"; // or use booleans here
} else {
echo "mail send ... ERROR!";
print_r( error_get_last() );
}
}

If you do it with PHP's mail() function,it difficult to find bugs.Download the PHPMailer script from here: http://github.com/PHPMailer/PHPMailer and include the main script file.
<?php
$email = new PHPMailer();
$email->From = 'From mail id';
$email->FromName = 'from name';
$email->Subject = 'Subject of message';
$email->Body = $bodytext;//body of the subject
$email->AddAddress( 'receiver email id' );
$file_path = 'path of the file you want to attach';
$email->AddAttachment( $file_path , 'filename' );
return $email->Send();
?>
