i want when a user uploads a pdf from frontend, it automatically gets embedded in the post. i am using following code for that but didn’t get the result.

// Handle form submission
function handle_pdf_submission() {
  // Check if form was submitted
  if (isset($_POST['submit_pdf'])) {
    // Get PDF file from form
    $pdf_file = $_FILES['pdf_file'];
    
    // Upload PDF file to server
    $upload = wp_upload_bits($pdf_file['name'], null, file_get_contents($pdf_file['tmp_name']));
    $pdf_url = $upload['url'];
    
    // Embed PDF file
    $pdf_embed = '[pdf-embedder url="' . $pdf_url . '"]';
    
    // Create new post with embedded PDF file
    $post = array(
      'post_title' => 'New PDF Post',
      'post_content' => $pdf_embed,
      'post_status' => 'publish',
      'post_type' => 'PDFs',
    );
    
    $post_id = wp_insert_post($post);
    
    // Redirect to success page
    wp_redirect('/pdf-submission-success/');
    exit;
  }
}

// Display form on frontend
function display_pdf_submission_form() {
  ?>
  <form method="post" enctype="multipart/form-data">
    <label for="pdf_file">Upload PDF:</label>
    <input type="file" id="pdf_file" name="pdf_file">
    <br><br>
    <input type="submit" name="submit_pdf" value="Submit PDF">
  </form>
  <?php
}

// Shortcode to display form on a page
function pdf_submission_form_shortcode() {
  ob_start();
  display_pdf_submission_form();
  return ob_get_clean();
}
add_shortcode('pdf_submission_form', 'pdf_submission_form_shortcode');

// Add form action to current page URL
function add_pdf_submission_form_action($form) {
  $form_action = get_permalink();
  return str_replace('<form', '<form action="https://adify.in/project/aamarsahitya/submit-pdf/' . $form_action . '"', $form);
}
add_filter('pdf_submission_form_shortcode', 'add_pdf_submission_form_action');

// Handle form submission on init
add_action('init', 'handle_pdf_submission');

// Add filter to automatically embed PDF file
function embed_pdf_file($content) {
  if (is_singular('PDFs')) {
    $attachments = get_posts(array(
      'post_type' => 'attachment',
      'post_mime_type' => 'application/pdf',
      'post_parent' => get_the_ID(),
    ));
    
    if ($attachments) {
      foreach ($attachments as $attachment) {
        $pdf_embed = '[pdf-embedder url="' . wp_get_attachment_url($attachment->ID) . '"]';
        $content = str_replace('[pdf-embedder]', $pdf_embed, $content);
      }
    }
  }
  
  return $content;
}
add_filter('the_content', 'embed_pdf_file');

Kindly help.
