WP mail attachment from form without upload file on filemanager

Well I had to come up with workaround for this one

What I did is

1. Upload the file to the server
2. email with wp-mail
3. on successful email or not; unlink the uploaded image

1.Upload the file to the server

    /*image upload *//* GET File Variables */$target_dir = $_SERVER['DOCUMENT_ROOT']. "/uploads/";$image_name = $_FILES['YOUR_IMAGE']['name'];$target_file = $target_dir . basename($_FILES['YOUR_IMAGE']['name']);$uploadOk = 1;$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));// Check if image file is a actual image or fake image$check = getimagesize($_FILES["YOUR_IMAGE"]["tmp_name"]);if($check !== false) {    echo "File is an image - " . $check["mime"] . ".";    $uploadOk = 1;} else {    echo "File is not an image.";    $uploadOk = 0;}// Check file sizeif ($_FILES["YOUR_IMAGE"]["size"] > 500000) {    echo "Sorry, your file is too large.";    $uploadOk = 0;}// Allow certain file formatsif($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"    && $imageFileType != "gif" ) {    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";    $uploadOk = 0;}// Check if $uploadOk is set to 0 by an errorif ($uploadOk == 0) {    echo "Sorry, your file was not uploaded.";    // if everything is ok, try to upload file} else {    if (move_uploaded_file($_FILES["YOUR_IMAGE"]["tmp_name"], $target_file)) {        echo "The file ". basename( $_FILES["YOUR_IMAGE"]["name"]). " has been uploaded.";    } else {        echo "Sorry, there was an error uploading your file.";    }}$attachment = array($target_file);

2.email with wp-mail

    $to = $Email; // put your email here        $headers = array('Content-Type: text/html; charset=UTF-8','From:' . $name . '<' . $fromEmail . '>');        // $headers = 'From:' . $name . '<' . $studentEmail . '>' . "\r\n"; // put user's email here or duplicate your email        $subject = 'Apply Online Form';        if (wp_mail($to, $subject, $message, $headers, $attachment ) === false) {            echo "Error";             unlink($target_file);        } else {             unlink($target_file);            echo "<h3> Mail Sent Successfully</h3>";        }

3.on successful email or not unlink the uploaded image

unlink($target_file);
