html2pdf's Issues

wkhtmltopdf is not recognized as an internal or external command

What steps will reproduce the problem?

in my main.php

'html2pdf' => [
            'class' => 'yii2tech\html2pdf\Manager',
            //'viewPath' => '@app/views/pdf',
            'converter' => [
                'class' => 'yii2tech\html2pdf\converters\Wkhtmltopdf',
                'defaultOptions' => [
                    'pageSize' => 'A4'
                ],
            ]
        ],

I installed the windows version here

https://wkhtmltopdf.org/downloads.html

What do you get instead?

Unable to convert file 'C:\xampp\htdocs\yii2\frontend\runtime\html2pdf\wkh3801.tmp.html': 'wkhtmltopdf' is not recognized as an internal or external command,
operable program or batch file.

How do i get it to work on my localhost? and once i move my site to my ubuntu server? What am i missing here? Thanks

One remark about wkhtmltopdf and options

It has taken me "ages" to get the cover, headers and footers and toc correctly rendered into the pdf.

The problem was that the order in the command of the option is important!

If the order is something like:
cover, header-html, footer-html
The headers and footers wont be rendered

cover, toc, header-html, footer-html
The headers and footers will only be on the toc page.

The order is impotent!
The options must be used in that order:
header-html, footer-html, cover, toc

To get the cover (which is rendered without header footer), toc (with header footer) and all other pages with header + footer rendered.

I found this here:
https://stackoverflow.com/questions/10583272/wkhtmltopdf-header-on-every-page

maybe it will be good if those options are added to the command manually and not by
foreach ($this->normalizeOptions($options)

At least this is the issue with the windows version wkhtmltopdf 0.12.4 (with patched qt)

why do not display image? i use xvfb-run wxhtmltopdf

Problem with sending the PDF

Hi i have created a pdf from a view.
The pdf is correctly rendered.

How can i "send" the file?
I tried:

 $pdf->send($file, $options = ['inline'=> false]);
 $pdf->send($file, $options = ['inline'=> false]);

But always getting an error.
The problem is that the Tempfile destructor deletes the file automatically on php end.
https://github.com/yii2tech/html2pdf/blob/master/src/TempFile.php#L36

So that the File couldn't been send because it's already deleted.

If i remove that line the file sending works flawlessly.

Wouldn't at be better to delete the file after download?

 Yii::$app->response->sendFile($pdf->name)->on(\yii\web\Response::EVENT_AFTER_SEND, function ($event) {
       unlink($event->data);
 }, $pdf->name);

Of course i could create another copy of that file, but then i don't understand the functions to send that file.

But maybe there is another solution which i don't know to prevent the call of the __destruct call.

Possible reasons:
No closed an open file pointer in class TempFile method send

wrong parameter pageSize is documentation for wkhtmltopdf used

After the documentation https://wkhtmltopdf.org/usage/wkhtmltopdf.txt
and the manual printed by -h option.

The parameter is page-size not pageSize as it is used in the readme
https://github.com/yii2tech/html2pdf/blob/master/README.md

if the same "defaultOptions" should be used regarding if the converter is mpdf or wkhtmltopdf then it must be replaced for wkhtmltopdf.

Anyhow the given examples sets pageSize for the wkhtmltopdf which is not correct.

Getting unknown property: yii\web\Application::html2Pdf

Yii::$app->html2pdf
->convert($html)
->saveAs('/path/to/output.pdf');
It gives following error
Getting unknown property: yii\web\Application::html2Pdf

Mpdf\MpdfException: Temporary files directory is not writable

When calling yii2tech\html2pdf\Manager::convert() with mPDF as the converter, the following exception is thrown:

Mpdf\MpdfException: Temporary files directory "/my-project/vendor/mpdf/mpdf/src/Config/../../tmp" is not writable in /my-project/vendor/mpdf/mpdf/src/Cache.php:17

#11 /my-project/web/index.php(31): yii\base\Application->run()
#12 {main}

This happens because the constructor of the main mPDF object requires tempDir to be already properly configured when instantiating its Mpdf\Cache in Mpdf\Mpdf::__construct() (line 983 in v7.1.0):

$this->cache = new Cache($config['tempDir']);

the default value for which comes from Mpdf\Config\ConfigVariables::$defaults:

$this->defaults = [
    ...
    'tempDir' => __DIR__ . '/../../tmp',
    ...
];

but your yii2tech\html2pdf\converters\Mpdf::convertInternal() does not set it to a valid value when instantiating mPDF:

$pdf = new \Mpdf\Mpdf([
    'mode' => $charset,
    'format' => $pageSize,
]);

so that even setting tempDir properly in yii2tech\html2pdf\converters\Mpdf::$defaultOptions has no effect.

Get cracking! 😉

Convert Page of Yii2 site

Is there are posibility to convert html page that generates from controller/view with css and other like in mPDF

i have page:
site.com/page/

how can i generate pdf from this page

mPDF its like this:

class PrintController extends Controller
{
    public function actionPrint()
    {
        $this->layout = "print";
..................
        $render = $this->render('....................', [
           .......................
        ]);
        $mpdf = new Mpdf(
            [
                'mode' => '+aCJK',
                "autoScriptToLang" => true,
                "autoLangToFont" => true,
            ]
        );

        $mpdf->SetMargins(0,0,5);
        $mpdf->SetDisplayMode('fullpage');
        $stylesheet = file_get_contents('........................'); // external css
        $mpdf->WriteHTML($stylesheet,1);
        $mpdf->WriteHTML($render);
        $mpdf->Output();
    }

or u can save it to file.

html2pdf can do like this?
