[sarathiscookie]

I have added code but getting some error.

<?php // if you are using composer, just use this include 'vendor/autoload.php'; use Gufy\PdfToHtml\Config; // change pdftohtml bin location Config::set('pdftohtml.bin', 'poppler-0.37/bin/pdftohtml.exe');

// change pdfinfo bin location Config::set('pdfinfo.bin', 'poppler-0.37/bin/pdfinfo.exe'); // initiate $pdf = new Gufy\PdfToHtml\Pdf('file.pdf');

// convert to html and return it as Dom Object $html = $pdf->html();

var_dump($html); // check if your pdf has more than one pages $total_pages = $pdf->getPages();

// Your pdf happen to have more than one pages and you want to go another page? Got it. use this command to change the current page to page 3 $html->goToPage(3);

// and then you can do as you please with that dom, you can find any element you want $paragraphs = $html->find('body > p');

?>

Error getting is

Config::set('pdftohtml.bin', 'poppler-0.37/bin/pdftohtml.exe');

Assuming you have installed the poppler-utils. The code above, please use the absolute path instead of relative path.

[sarathiscookie]

Thanks it's a path problem. I have set full path and currently no error is showing. But the page is blank.

// change pdftohtml bin location Config::set('pdftohtml.bin', 'C:/xampp/htdocs/pdf-to-html-master/poppler-0.37/bin/pdftohtml.exe');

// change pdfinfo bin location Config::set('pdfinfo.bin', 'C:/xampp/htdocs/pdf-to-html-master/poppler-0.37/bin/pdfinfo.exe'); // initiate

[mgufrone]

Hai, can you give me your pdf you're using? i would like to test it on my device, too.

[KenFlip]

Hi @mgufrone ,

I am using a mac with a local version of my site on mamp, I am using the code below to run a test on a 5 page pdf:

<?php // if you are using composer, just use this include 'vendor/autoload.php';

// change pdftohtml bin location
\Gufy\PdfToHtml\Config::set('pdftohtml.bin', '/usr/local/bin/pdftohtml');

// change pdfinfo bin location
\Gufy\PdfToHtml\Config::set('pdfinfo.bin', '/usr/local/bin/pdfinfo');

// initiate
$pdf = new Gufy\PdfToHtml\Pdf(BASE_PATH . 'uploads/pdf/test.pdf');

// convert to html and return it as [Dom Object](https://github.com/paquettg/php-html-parser)
$html = $pdf->html();

echo $html;

?>

This is the response I am getting:

Please could you help me out as this is really urgent!

Thanks in advance.

[KenFlip]

@sarathiscookie Please if you could help me?

[mgufrone]

@KenFlip have you installed poppler-utils? if you haven't, please use this command below

brew install poppler

[KenFlip]

Hi, I ran that command and it installed a lot of things what folder was i supposed to run the command in? Kindest Regards Kenton

[KenFlip]

So I ran it again just incase in my localhost root directory and in my actual site root directory and both times i got this:

Warning: poppler-0.43.0 already installed

[mgufrone]

It doesn't matter where you run the command in. It will install on the global directory. Okay, next is check if you have properly installed the required package.

which pdfinfo

which pdftohtml

if it is the same location as your code, the code you wrote up there will run fine

[KenFlip]

Ran those two:

which pdfinfo gives me: /usr/local/bin/pdfinfo which pdftohtml gives me: /usr/local/bin/pdftohtml

My code is:

// change pdftohtml bin location
\Gufy\PdfToHtml\Config::set('pdftohtml.bin', '/usr/local/bin/pdftohtml');

// change pdfinfo bin location
\Gufy\PdfToHtml\Config::set('pdfinfo.bin', '/usr/local/bin/pdfinfo');

[mgufrone]

So, how was it? still not working or else?

[KenFlip]

Still not working at all...

Giving me that same error

[KenFlip]

I can send you the pdf if you would like... my end goal out of this, is the user must be able to download a pdf form. fill it out upload it to the site and get a results page containing some of the information from the uploaded pdf...

If that makes sense.

When they fill it out, the pdf will have input fields and stuff like that, so not writing or anything

[mgufrone]

Okay, send me the pdf to my email. I will check it out. :3

[KenFlip]

so if I have a plain text pdf will that work?

[mgufrone]

Yap, static pdf will work.

[KenFlip]

Could you possibly email me a plain text pdf that works on your system, I just want to see if I can get this work on my side. I can try convert the pdf form to a plain text pdf and then run t through

[mgufrone]

Hang on a sec, do you run your code through browser? or just from command line?

[KenFlip]

through a browser

[KenFlip]

That pdf you sent me doesnt work...

[mgufrone]

Oh. PHP, by default, disable shell_exec command, that is needed by the package. You should enable shell_exec function to run the package command.

[KenFlip]

Have no idea how to do that or even where to do that...

Hello!

I was fighting many hours with this library (was getting the same error, that guys before).

After long time of debuging I noticed that $content in Pdf.php:22 is empty.

Finally added 2>&1 to the shell command, so I got: $content = shell_exec($this->bin()." '".$this->file."' 2>&1"); Content then was able to get errors.

What finally turned out, the system could not see my pdf, even though the path was full and correct. I was getting 'I/O Error: Couldn't open file ''test.pdf'': No error.

Removed the ' ' from the code so I got: $content = shell_exec($this->bin()." ".$this->file);

And voila! $content is now filling up with data.

But I started to getting warnings with getting html output like "(...)test-1.html: failed to open stream: No such file or directory" [src/Html.php:36]

Weird thing is, that the displayed path exists! When copy-pasting it to the explorer I can see the HTML file. Sample path is: C:_MY_FILES\PROJECTS\eclipse_workspace\htdocs\My_Project\vendor\gufy\pdftohtml-php\src/../output/57ea99fab3250/test-1.html

When opened it manually I can see the file content as "something failed". Probably two new problems. One with path somehow, second that parsed html is not generated. No power to continue this fight. :-|

@mgufrone

I have follow all step, but i get still error, which posted below

Fatal error: Uncaught exception 'Exception' with message 'You're asking to go to page 1 but max page of this document is 0' in D:\wamp\www\test\pdftohtml\vendor\gufy\pdftohtml-php\src\Html.php on line 63 Fatal error: Uncaught exception 'Exception' with message 'You're asking to go to page 1 but max page of this document is 0' in D:\wamp\www\test\pdftohtml\vendor\gufy\pdftohtml-php\src\Html.php on line 63

I am using window system and download poppler from http://blog.alivate.com.au/poppler-windows/

Directory structure as below

poppler /bin/ vendor /all required vendor

I am not getting about below step

$ which pdfinfo /usr/local/bin/pdfinfo

$ which pdftohtml /usr/local/bin/pdfinfo

Is it required to install? If yes, then how to install in window system? Because in cmd "which" command not working.

Please provide me needful solutions.

[mgufrone]

@jimeshgajera Have you read this part? If so, have you change the binary location on the configuration?

[jimeshgajera]

@mgufrone , From where to read this part?

`include 'vendor/autoload.php'; use Gufy\PdfToHtml\Config; // change pdftohtml bin location Config::set('pdftohtml.bin', 'D:/wamp/www/pdftohtml/poppler/poppler/bin/pdftohtml.exe');

// change pdfinfo bin location Config::set('pdfinfo.bin', 'D:/wamp/www/pdftohtml/poppler/bin/pdfinfo.exe'); // initiate $pdf = new Gufy\PdfToHtml\Pdf('file.pdf');

// convert to html and return it as Dom Object $html = $pdf->html();`

i have set above location for poppler

[mgufrone]

Okay, I will take a look into it. I will inform you what I found

I'm really struggling with the error @garbus points out:

But I started to getting warnings with getting html output like "(...)test-1.html: failed to open stream: No such file or directory" [src/Html.php:36]

Unlike him my server is Linux based. Please help.

[drewgash]

I found the issue.

sudo yum install poppler-utils

That installs an old version (0.12.4) which does not have pdftohtml command options like "-s" and "-fmt".

Go to this page https://medium.com/@jakebathman/building-poppler-utils-for-centos-6-5-really-e52eccffc6ae to guide you on how to get a later version of poppler-utils. I installed https://poppler.freedesktop.org/poppler-0.22.5.tar.gz instead of 0.13.4 as instructed.

All the best!
