Laravel 5.1 Snappy PDF overwrite

Is there an option to overwrite the existing PDF file?

I have this function:

public function quote($id){

    $quote          = Quotes::find($id);
    $last_quote     = sprintf("%'.04d\n", $quote->quote_number);
    $customer       = Customer::find($quote->customer_id);
    $items          = $quote->Items()->get();
    $fullinfo       = json_decode($quote->fullinfo);
    $token          = $quote->Tokens()->first();

    $data = [
        'quote'         => $quote,
        'last_quote'    => $last_quote,
        'customer'      => $customer,
        'items'         => $items,
        'fullinfo'      => $fullinfo,
        'token'         => $token,
    ];

    $pdf = App::make('snappy.pdf.wrapper');

    $pdf->LoadView('quotes.quote_print', $data)
        ->setOption('page-size', 'A4');
    $path = storage_path() . "/quotes/{$customer->name}/cotizacion.pdf";
    $pdf->save($path);
    return $pdf->stream();


}

The problem is that when i run that function for the second time i get a file already exist error.

My solution is to delete the file to be overwritten.

Versions

knplabs/knp-snappy v1.3.1 knplabs/knp-snappy-bundle v1.8.0

PDF creation logic (running under Ibexa community edition/Symfony)

private function _makePdf(ContentView $view) {
        $pdfFilename = $this->baseDir . $this->pdfUrl . '.pdf';
        unlink($pdfFilename);
        $html = $this->render($view->getTemplateIdentifier(), $view->getParameters());
        $this->knpSnappyPdf->generateFromHtml(
                $html->getContent(),
                $pdfFilename
        );
    }

I faced the same issue today in laravel.

Exit with code 1 due to network error: ContentNotFoundError

I tried to wrap my all css and script link with url() function.

Example:
Replace
        <link href="/css/bootstrap.min.css" rel="stylesheet">
to         
    <link href="{{url('/css/bootstrap.min.css')}}" rel="stylesheet">
And Replace
    <script src="{{url('/js/jquery-2.1.1.js')}}"></script>
To
    <script src="{{url('/js/jquery-2.1.1.js')}}"></script>

and my code working. Now every thing is fine. :)

What i did was to add the overwrite function to save(), like this:

public function save($filename, $overwrite = true)
{

    if ($this->html)
    {
        $this->snappy->generateFromHtml($this->html, $filename, $this->options, $overwrite);
    }
    elseif ($this->file)
    {
        $this->snappy->generate($this->file, $filename, $this->options, $overwrite);
    }

    return $this;
}

I have made a pull request for this: https://github.com/barryvdh/laravel-snappy/pull/76 , but this uses $overwrite = false as default

If assume you are using barryvdh/laravel-snappy with laravel 5.1

The function save() you are using to save doesn't support overwrite flag, it internally calls generateFromHtml that does support overwrite flag, the fourth argument.

see the save method in \vendor\barryvdh\laravel-snappy\src\PdfWrapper.php

public function save($filename)
{

    if ($this->html)
    {
        $this->snappy->generateFromHtml($this->html, $filename, $this->options);
    }
    elseif ($this->file)
    {
        $this->snappy->generate($this->file, $filename, $this->options);
    }

    return $this;
}

I would recommend you to use the following method of saving the view to pdf

public function quote($id){

    $quote          = Quotes::find($id);
    $last_quote     = sprintf("%'.04d\n", $quote->quote_number);
    $customer       = Customer::find($quote->customer_id);
    $items          = $quote->Items()->get();
    $fullinfo       = json_decode($quote->fullinfo);
    $token          = $quote->Tokens()->first();

    $data = [
        'quote'         => $quote,
        'last_quote'    => $last_quote,
        'customer'      => $customer,
        'items'         => $items,
        'fullinfo'      => $fullinfo,
        'token'         => $token,
    ];

    $pdf = App::make('snappy.pdf.wrapper');

    $html = view('quotes.quote_print', $data))->render();
    $path = storage_path() . "/quotes/{$customer->name}/cotizacion.pdf";

    //public function generateFromHtml($html, $output, array $options = array(), $overwrite = false)
    $pdf->generateFromHtml($html, $path,[],$overwrite = true);
    return $pdf->stream();


}

Hope this helps,

K
