获取Laravel控制器中的当前视图

Question

What I try to do : I want to generate PDF of the current view More details: : I got many clients and I want to create a button on each page so that I can generate PDF of each clients details.

Laravel package: https://github.com/barryvdh/laravel-dompdf

What I have done up to now :

1. I added DomPdf to my application
2. I created a Route::resource('imprimer', 'PrintController'); route
3. I added a PrintController

class PrintController extends \BaseController{

    public function show(){
      $pdf = PDF::loadView('clients.show');
      return $pdf->stream();
}}

4. I included a link in my view (2 versions)

{{ HTML::linkAction('PrintController@show', 'PDF',array(), array('class'=>'btn btn-primary pull-right mgright10')) }}

<a href="{{ URL::to('imprimer/' . $client->id) }}">Pdf2</a>

My question : How to pass to current view (ex: clients/1) to the controller so that the controller generates a PDF of the current page?

Answer 1

You have to set a variable that contains the current view name, since there's no built in method for that. We can use View::composer which is basically a callback for when a view gets rendered.

View::composer('*', function($view){
    View::share('view_name', $view->getName());
});

If it only affects certain views you could also restrict it by changing * to another mask.

So now you can do:

{{ HTML::linkAction('PrintController@show', 'PDF', array($view_name), array('class'=>'btn btn-primary pull-right mgright10')) }}

And receive it in your controller:

public function show($viewName){
   //...
}

I found how (I was close to it). Here is how I did for reference:

PrintController.php

class PrintController extends \BaseController{
public function show($id)
{
    $client_id = Client::find( $id );
    $html = View::make( 'clients.show' )->withClient( $client_id );
    $pdf = App::make( 'dompdf' );
    $pdf->loadHTML( $html );
    return $pdf->stream();
    }
}

View

<a href="{{ URL::to('imprimer/'.$client->id) }}">
  <button>PDF</button>
</a>

Route.php

Route::resource('imprimer', 'PrintController');

I managed to create a new way to call the "create PDF" function without having to add code to the PrintController.

PrintController.php

<?php
class PrintController extends \BaseController{

public function show( $id )
{
if( isset($id) )
{
    /** remove last 2 character */
    $class_name = substr( $id, 0, -2 );

    /** Stay only last character */
    $id = substr( $id, -1 );

    if( isset($class_name) )
    {
        $with_method = 'with'.ucfirst( $class_name ); // withClient
        $find_method = ucfirst( $class_name ); // Client
        $html = View::make( $class_name .'s.show' )->$with_method( $find_method::find($id) );    
    }
    else
    {
        $html = 'Data Not Found!';
    }

    $pdf = App::make( 'dompdf' );
        $pdf->loadHTML( $html );
        return $pdf->stream(); 
}
}
}

View (Only the client and $client to remplace)

<a href="{{ URL::to('imprimer/'.'client='. $client->id) }}" target="_blank">
  <button class="btn btn-primary pull-right mgright10">PDF2</button>
</a>
