如何将表单的值传递给另一个表单 PHP？

Question

I have a form A in index.php which I need to pass the value of 'notebook_id' to formB in create_new_note.php. I used POST method to do this but it is not working.

form A in index.php

 <!-- Modal --> <div class="modal" id="newNotebookModal" tabindex="-1" aria-labelledby="newNotebookModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <center><h5 class="modal-title" id="newNotebookModalLabel">Create a New Notebook</h5></center> </div> <div class="modal-body"> <form class="forms-sample" method="post"> <div class="form-group"> <label for="notebook_name_label">Notebook Name</label> <input type="text" class="form-control" name="notebook_name" id="notebook_name" placeholder="Notebook Name"> </div> </div> <div class="modal-footer"> <button class="btn btn-outline-secondary btn-fw">Cancel</button> <input type="submit" class="btn btn-primary" name="submit" value="Create"/> </div> </form> </div> </div> </div> </div>

Form B

 <form class="forms-sample" method="post"> <div class="form-group"> <label for="note_title_label">Title</label> <input type="hidden" name="notebook_id" value="<?php echo $notebook_id; ?>"> <input type="text" class="form-control" name="note_title" id="note_title" placeholder="Title"> </div> <div class="form-group"> <textarea class="form-control" name ="note_content"id="note_content" rows="40"></textarea> </div> <button class="btn btn-outline-secondary btn-fw">Cancel</button> <input type="submit" class="btn btn-primary" name="submit" value="Create"/> </form>

I used MVC framework, hence this is my Controller code and Model code

// Controller

function addNotebook($std_id) {
    $notebook = new ManageNotesModel();
    $notebook->std_id = $std_id;
    $notebook->notebook_name = $_POST['notebook_name'];
   
    if($notebook->addNotebook() > 0) {
      $message = "Your notebook has been created!";
      echo "<script type='text/javascript'>alert('$message');
      window.location = '../ManageNotesView/create_new_note.php'</script>";
    }
  }

// Model
function addNotebook(){
  $sql = "insert into notebook(std_id,  notebook_name)values(:std_id, :notebook_name)";
  $args = [':std_id'=> $this->std_id, ':notebook_name'=>$this->notebook_name];
  $stmt = DB::run($sql, $args);
  $count = $stmt->rowCount();

  return $count;
}

Please help me, I'm new to this I tried to make way through it, but cant seem to figure out whats wrong

As I see your code is creating a new row in the database. After saving row into database you want to know the last inserted id of the entity called Notebooks. Reuse that value and pass it into your template of creating titles. If your MVC framework does not know the last inserted id, you should customize it and add functionality to do that. Check last_inserted_id
