html - Sending an image to email from web forms using php

Question

I am trying to send an image file from web forms to email, but it keeps sending an empty attachment. I have tried so many things, from changing emails to see if gmail is the problem, but it's all the same no matter what I try. Below is my code so far.

$tmpName = $_FILES['dl_image']['tmp_name'];
$fileType = $_FILES['dl_image']['type'];
$fileName = $_FILES['dl_image']['name'];
$size     = $_FILES['dl_image']['size'];

if (file($tmpName))
    {
    /* Reading file ('rb' = read binary)  */
    $file = fopen($tmpName,'rb');
    $data = fread($file, $size);
    fclose($file);

    /* Encoding file data */
    $encoded_content = chunk_split(base64_encode(file_get_contents($data)));

    $boundary = md5(date('r', time())); // define boundary with a md5 hashed value

    $headers = "MIME-Version: 1.0
"; // Defining the MIME version 
    $headers .= "Content-Type: multipart/mixed;
"; // Defining Content-Type 
    $headers .= "boundary = $boundary
"; //Defining the Boundary 

    $body .= "--$boundary
"; 
    $body .="Content-Type: $fileType; name=".$fileName."
"; 
    $body .="Content-Disposition: attachment; filename=".$fileName."
"; 
    $body .="Content-Transfer-Encoding: base64
"; 
    $body .="X-Attachment-Id: ".rand(1000, 99999)."

";  
    $body .= $encoded_content; // Attaching the encoded file with email

    $sentMailResult = mail($receiver, $subject, $body, $headers);

    if($sentMailResult )  
    { 
       echo "File Sent Successfully."; 
       unlink($fileName); // delete the file after attachment sent. 
    } 
    else
    { 
       die("Sorry but the email could not be sent. Please go back and try again!"); 
    } 
} 

And also below is my html code. I was thinking may the problem could be from the html code, but all attachment attributes parse correctly.

                    <div class="file-upload">
                      <button class="file-upload-btn" type="button" onclick="$('.file-upload-input').trigger( 'click' )">Add Image</button>

                      <div class="image-upload-wrap">
                        <input class="file-upload-input" type="file" name="dl_image" onchange="readURL(this);" accept="image/*" />
                        <div class="drag-text">
                          <h3>Drag and drop a file or select add Image</h3>
                        </div>
                      </div>
                      <div class="file-upload-content">
                        <img class="file-upload-image" src="#" alt="your image" />
                        <div class="image-title-wrap">
                          <button type="button" onclick="removeUpload()" class="remove-image">Remove <span class="image-title">Uploaded Image</span></button>
                        </div>
                      </div>
                    </div>
