Passing id to pdf printing with cakephp3 and tcpdf

Question

Personal I am generating reports in pdf and I am with the following problem, I need to set the id of the volunteer to print the pdf with the data of the volunteer, I tried as follows by the link:

view

<?= $this->Html->link(__('Imprimir'), ['action' => 'pdf_view2', $voluntario->id], ['class'=>'btn btn-info btn-xs']) ?>

it turns out that even though pdf printing obeys only the id I pass in the controller, so if I pass null, it comes null, if I pass the normal id as 2... comes the volunteer number 2... as I can pass the volunteer id to pdf_view?

controller

public function pdf_view2($schedule_id = null, $id = 2){        
      $this->viewBuilder()->layout('ajax');
      $this->set('title', 'My Great Title');
      $this->set('file_name', '2016-06' . '_June_CLM.pdf');
     $this->response->type('pdf');


  /*  $this->paginate = [
        'contain' => ['Oficinas']
    ];
    $voluntarios = $this->paginate($this->Voluntarios);
    

    $this->set(compact('voluntarios'));*/

    $voluntario = $this->Voluntarios->get($id, [
        'contain' => ['Oficinas']
    ]);

    

    $this->set('voluntario', $voluntario);

I need to take this id=2 and put so that it takes the volunteer id, how to do?

Answer 1

Your method should look like this:

    public function pdf_view2($schedule_id = null, $id = null)
    {
      $this->viewBuilder()->layout('ajax');
      $this->set('title', 'My Great Title');
      $this->set('file_name', '2016-06' . '_June_CLM.pdf');
      $this->response->type('pdf');
      
      $voluntario = $this->Voluntarios->get($id, [
            'contain' => ['Oficinas'],
        ]);

        $this->set('voluntario', $voluntario);
    }

Here on this line:

<?= $this->Html->link(__('Imprimir'), ['action' => 'pdf_view2', $voluntario->id], ['class'=>'btn btn-info btn-xs']) ?>

You need to see what is being passed on $voluntario->id

This is what is going to the parameter. You need to see if you are loading the id correctly!

Answer 2

Change that line:

public function pdf_view2($schedule_id = null, $id = 2){

To:

public function pdf_view2($id = null, $schedule_id = null){

Its function receives the ID of your URL in the first parameter and not in the second.
