DOMPDF_Exception "No block-level parent found. Not good."

[TomasNiDo]

Hi, im working on a project and I'm using your dompdf to create and render PDFs. Rendering PDFs is a success on my localhost but what's odd is it throws DOMPDF_Exception "No block-level parent found. Not good." error on live server. Any idea how to fix this?

Im using loadView() function..

[rayk-ri]

I'm having a similar issue when using the loadView method:

DOMPDF_Exception in inline_positioner.cls.php line 37:
No block-level parent found. Not good.

DOMPDF_Exception in inline_positioner.cls.php line 37:
No block-level parent found. Not good.

What is the problem?

[rayk-ri]

Here's how I'm using loadView:

$pdf = \App::make('dompdf.wrapper');
$pdf->loadView('foo.bar', $foobar);
return $pdf->stream();

Here's the stack trace I'm getting:

Guys, the problem in CSS.
I removed the CSS and it worked. DOMPDF use CSS 2.1.

[rayk-ri]

Worked for me too.
Thanks Nick!

I was able to fix this error by remove this CSS definition in de body section

        body {
           ...
           display: table;
           ...
        } 

Switched everything back on, even the fonts (who are responsible for massive delay when included) and it worked, so the display:table is the culprit here.

Also try to prevent line breaks in your template (if you're using one) - this caused this error in my case.

I have this problem on Mac OS X using any PHP version and libxml2 2.9.5 (I have different PHP versions compiled against it). I used the ugly hack for strip spaces between tags.

The bug is detailed on this dompdf issue: dompdf/dompdf#1494

[frin]

Thanks for that link @vaites I used another better solution on that page which is:

use Dompdf\Options;
$options = new Options();
$options->set('enable_html5_parser', true);
$dompdf = new Dompdf($options);

You have to set option enable_html5_parser to true, then it works again with libxml2 2.9.5 or newer.
This also fixed the issue of "Cannot redeclare ...." function, if you had any PHP functions inside the template/HTML.

Dompdf was working fine with php5.5.12 but on changing php version to 7.0.25 it stopped working and throwing this error.

An uncaught Exception was encountered

Type: DOMPDF_Exception

Message: No block-level parent found. Not good.

Filename: D:\wamp\www\ci316\application\libraries\dompdf\include\inline_positioner.cls.php

Line Number: 37

How to resolve this????

I removed all css still not working.

[gbrits]

Removing the entire HEAD section fixed my issue. Use inline styles, like an EDM.

After resolving all errors i am getting this error please give solution how to resolve this issue

The solution from @frin seems to be doing the trick! Better than debugging your html template.
I used $dompdf->set_option('enable_html5_parser', TRUE); to enable the option.

[Nesdf]

I fixed with "composer update"

[jglantonio]

I solved , deleting tag title.

This a message that i found on log after enable the log:
PHP Fatal error: Call to a member function get_node() on a non-object in /home/nfe/public_html/vendor/dompdf/dompdf/include/inline_positioner.cls.php on line 32

And this is the code near line 32:
if ( !$p )
throw new DOMPDF_Exception("No block-level parent found. Not good.");

$f = $this->_frame;

$cb = $f->get_containing_block();
$line = $p->get_current_line_box();

[DuncanFairley]

Just got this after a libxml2 update to 2.9.7.
I updated to dompdf 0.8.2 but the issue remains.

[tarhe]

Change:

public function loadView($view, $data = array(), $mergeData = array(), $encoding = null){
     $html = $this->view->make($view, $data, $mergeData)->render();
     return $this->loadHTML($html, $encoding);
 }

To:

public function loadView($view, $data = array(), $mergeData = array(), $encoding = null){
     $html = $this->view->make($view, $data, $mergeData)->render();
     $html = preg_replace('/>\s+</', '><', $html);
     return $this->loadHTML($html, $encoding);
 }

in /vendor/barryvdh/laravel-dompdf/src/PDF.php

Notice: $html = preg_replace('/>\s+</', '><', $html); in the second one.

[phoalmeida]

I didn't find any barryvdh/laravel-dompdf/src/PDF.php or public function loadView using grep.

Mine is dompdf, and on folder vendor there is only these folders:
composer filp laravel nesbot patchwork predis swiftmailer zizaco
bin d11wtq ircmaxell laravelbook nideia phenx psr symfony
classpreloader dompdf jeremeamia monolog nikic phpseclib stack zendframework

Any idea?

[victor-priceputu]

Had the same issue, for me it was caused by the html tag not being detected as a block-level parent.
Had to add the following CSS to fix it:
html, body { display: block; }

[vipinkumarvk]

"No block-level parent found. Not good."-if this is ur problem then the given below is one of its solution

Change lines 122 to 125 in /vendor/barryvdh/laravel-dompdf/src/PDF.php
From

public function loadView($view, $data = array(), $mergeData = array(), $encoding = null){
    $html = $this->view->make($view, $data, $mergeData)->render();
    return $this->loadHTML($html, $encoding);
}

To

public function loadView($view, $data = array(), $mergeData = array(), $encoding = null){
    $html = $this->view->make($view, $data, $mergeData)->render();
    $html = preg_replace('/>\s+</', '><', $html);
    return $this->loadHTML($html, $encoding);
}

[victor-priceputu]

NEVER change the code in your vendor folder. A pull request may be better than that. The next time you try to update the code, it will override the change and you are back to square 1. Plus how will you deploy? Normally the vendor folder is not supposed to be version controlled, so your change will not go beyond your local code.

My fix came with adding the following styling in the template:html, body {display: block;}

[markuszeller]

Enable before parsing via load_html(); solved it for me.
$oDompdf->set_option('enable_html5_parser', true);

[nzrubin]

try to minimize the HTML template for PDF (it will remove all the spaces and white spaces etc)
it worked for me

[alankarmore]

I was facing this same issue with Laravel 5.4 and "barryvdh/laravel-dompdf": "^0.7.1", but later I updated the version of dompdf to "barryvdh/laravel-dompdf": "^0.8", and issue resolved.
