No content in outputPath!

[AureliusHogan]

I upgraded from version 1.x to version 2.0 and did all of the upgrading changes.

<pdf:document sourceFile="fileadmin/template.pdf" outputPath="typo3temp/registration.pdf">

This statement leads to a registration.pdf equal template.pdf. If I use outputDestination="inline" the result has the content of template.pdf inlcuding all pdf:text statements I've set.

Why does registration.pdf don't carry any content? What could be missing?

If you use outputDestination="inline" then it is only returned inline to the browser, but not saved to the filesystem. If you want to save it to the filesystem you should use outputDestination="file" or outputDestination="file-inline" to save it AND return it to the browser.

Please see: https://docs.typo3.org/typo3cms/extensions/pdfviewhelpers/ConfigurationReference/TypoScriptReference/Index.html#document-outputdestination

I tested the different outputDestination values with the following example and everything seems to work as expected, the document is correctly saved to the filesystem.

Does this solve your issue? Or else, does it work with the example Extend Existing PDFs?

[AureliusHogan]

No that doesn't change anything. Thx. for the fast reply.

It's not that the file is not generated. The problem is that the content inside of the document is not generated. If I use "file-inline" the document shown is correct but the document saved is without content.

@AureliusHogan Currently I can not reproduce that issue. It seems strange to me, that the document that is returned inline, has different content than the file that is saved, because TCPDF actually reads the saved file to return it's content. See:

pdfviewhelpers/Resources/Private/PHP/tcpdf/tcpdf.php

Lines 7674 to 7679 in 1647367

	$f = TCPDF_STATIC::fopenLocal($name, 'wb');
	if (!$f) {
	$this->Error('Unable to create output file: '.$name);
	}
	fwrite($f, $this->getBuffer(), $this->bufferlen);
	fclose($f);

and

pdfviewhelpers/Resources/Private/PHP/tcpdf/tcpdf.php

Line 7689 in 1647367

TCPDF_STATIC::sendOutputData(file_get_contents($name), filesize($name));

Does this also happen with the example Extend Existing PDFs?
Does it work if you do not use the option sourceFile?
Did this work with v1.x? If yes, you could try to use an older version of TCPDF (v6.2.17, https://github.com/tecnickcom/TCPDF/releases)
Can you try to open the document that is saved to the filesystem with your browser?
Are there any errors in the error log?
Can you try to debug that place in TCPDF?
Can you provide your template and maybe corresponding controller action?

[AureliusHogan]

Yes, it worked with 1.x!
No errors in log file.
And now the realy strange thing. This is what I see in the browser:

And this is the file which is saved:
test-doc.pdf

And this is the file I get, when I save the inline file:
test-inline.pdf

That's crazy!!

[maechler]

I can view both files:

Maybe there is an issue with your PDF viewer?
Can you try to view the document test-doc.pdf in the browser? (Probably you can just drag and drop the document to your browser)
Or try to view test-inline.pdf with the viewer you used for test-doc.pdf.

[AureliusHogan]

Yes, I just now noticed, that Adobe Acrobat says the document has an error. So I tried to validate it as you mention in your documentation. The result is:

Now the question is, how to find the problem? The code I use is rather simple:

<pdf:document sourceFile="typo3conf/ext/pdfviewhelpers/Resources/Public/Examples/ExtendExistingPDFs/pdf_template.pdf" title="ESM PDF-Test" outputDestination="file-inline" outputPath="typo3temp/test.pdf">
	<pdf:page autoPageBreak="1" importPage="1" margin="{top: 58, right: 20, bottom: 40, left: 20}">
		<pdf:text>

There seems to be an issue with the renderHeader and renderFooter methods in BasePDF. You could try to provide your own class and overwrite these methods:

<?php
namespace Vendor\YourExtension\Model;

class MyPDF extends \Bithost\Pdfviewhelpers\Model\BasePDF
{
    public function renderHeader()
    {
    }

    public function renderFooter()
    {
    }
}

plugin.tx_pdfviewhelpers.settings {
    config {
       class = Vendor\YourExtension\Model\MyPDF
    }
}

As long as you do not need the header and footer ViewHelpers, this should work. I will investigate that issue. Thanks again for reporting!

[AureliusHogan]

Perfect!!
That does the job for my purposes.

Thanx for the prompt support!!

[maechler]

Actually it is even enough to just overwrite the footer method renderFooter .

@AureliusHogan I just released a new version v2.0.1 that should fix that issue. It would be nice if you could update the extension, remove the fix from yesterday and test whether this works for you.

If you like the project, please consider giving it a star :)

[AureliusHogan]

Yes, now everything is fine. And it seems like it is a little faster even.
Good job!
Perfekt support!

[maechler]

Perfect, thanks for reporting and testing!
