문제

right, I have installed the service provider for wkhtmltopdf (https://github.com/ignited/laravel-pdf) and when I add 

Route::get('/', function() {
    $pdf = PDF::make();
    $pdf->addPage('<html><head></head><body><b>Hello World</b></body></html>');
    $pdf->send();
});

in my routes.php it generates a pdf file.

What I am trying to do is to POST a whole div to my controller and then generate a PDF from that.

My form:

<form id="convert" action="{{{ URL::to('') }}}/pdf" method="post">
<input type="hidden" name="body" id="body">
<input type="submit" class="btn btn-success pdf" value="Done? Convert to PDF!">
</form>

the jQuery:

$('form#convert').submit(function(){
                  $("input#body").val($("#preview").html());
              });

routes.php:

Route::post('pdf', 'PdfController@index');

and finally my controller (PdfController):

<?php

class PdfController extends BaseController {

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {

        $data = Input::get('body');


                $pdf = PDF::make();
            $pdf->addPage($data);
            $pdf->send('test.pdf');
            if(!$pdf->send())
        return $pdf->getError();
    }



}

Somehow I think it;s a basic POST vs GET thing, or I'm not doing things right. Right now I get the error Could not run command '/var/www/docassembly/vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'

but if I replace my variable inside my controller by straight html I get the same error.

If I use GET in the form and the route and pass straight html as a parameter, the error is different:

Could not run command '/var/www/docassembly/vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64' test /tmp/tmp_WkHtmlToPdf_Hq98EZ: Loading pages (1/6) [> ] 0% [======> ] 10% [============================================================] 100% Error: Failed loading page http://test (sometimes it will work just to ignore this error with --load-error-handling ignore)

So having it in the controller is also an issue. Any leads?

Turns out the answer is quite simple, just needed to start the input with

<html><head></head><body> and end with </body></html>

As my input for whtml2pdf was the content of a div, I just had to insert those html tags into the value of the input being sent to the controller and voila.

다른 팁

According to the documentation of the package you have provided, it says that you need to include the binaries in your composer.json file to make it work:

Note (you must also include wkhtmltopdf binaries) 32-bit systems

{
    "require": {
        "h4cc/wkhtmltopdf-i386": "*"
    }
}

64-bit systems

{
    "require": {
        "h4cc/wkhtmltopdf-amd64": "*"
    }
}

You can include both of these if you need.

Sounds like Laravel is trying to execute the 64bit binary and can't find it. Make sure that:

  • You have it placed in the right folder.
  • It has execution permission set with chmod.
