Save as PDF Error

Posted: Sat Jul 14, 2012 1:51 pm

Is anyone else experiencing any problems with using the 'Save as PDF' function for news articles when the article includes an image. I am currently receiving the following error:

Quote:

TCPDF ERROR: [Image] Unable to get image: http://www.mywebsite.com//uploads/image/image.jpg

I have been trying to solve the problem with the help of Montego, but we've not been able to pin it down.

Any suggestions would be gratefully appreciated.

I tried to add an image but when I click on the pdf icon to safe as pdf, I get an error on the site. I am coming back with more details, I am testing more things.

Edited: Guys, jakec is right.

If I add an image to the article and I click on the icon to safe as pdf I get no results and my site gets stucked loading without any result. After removing the image then it works again.

Shocked

Strange!

unicornio, thanks for testing on your site.

What error are you getting?

In your site admin preferences, do you have a trailing / on the end of your Site URL?

Posted: Sat Jul 14, 2012 5:45 pm

No I don't have that but I will do it if it is necessary.

Edited

I tested with and without the slash and it doesn't work neither Sad

I know why you are asking us that. Result

.com//modules.php?name=News&file=article&sid=2#disqus_thread

If I have the slash / I will not get any result but if I don't put it. I won't get it neither. Nothing is showing. I'm getting Gateway error, blank page

I can't reproduce the issue. You may want to try the latest release of TCPDF from here:

http://sourceforge.net/projects/tcpdf/files/tcpdf_5_9_172.zip/download

You can just copy over the files in classes/tcpdf folder.

The bit of code that is returning the error is in tcpdf.php file:

Code:




if ($imsize === FALSE) {


         if (substr($file, 0, -34) == K_PATH_CACHE.'msk') { // mask file


            // get measures from specified data


            $pw = $this->getHTMLUnitToUnits($w, 0, $this->pdfunit, true) * $this->imgscale * $this->k;


            $ph = $this->getHTMLUnitToUnits($h, 0, $this->pdfunit, true) * $this->imgscale * $this->k;


            $imsize = array($pw, $ph);


         } else {


            $this->Error('[Image] Unable to get image: '.$file);


         }

and that bit of code relies on several functions within tcpdf. Have you tried to use a different image and see if the results are the same? I am wondering if it could be an upload issue with the image.

Thanks nuken I'm out at the moment, but I'll give this a go tonight.

nuken, I guess you are right. It has to do with an image. I tested with .jpg image and it worked perfect. I guess this is an issue wiht .png or other images.

I downloaded the file u suggested but I didn't upload it yet until you answer my question to be sure I don't mess anything up.

I noticed I have to remove example forlder but there are more files inside. Can u let us know what exactly I should upload to update the package?

Edited: I decided to update it but it didn't solve any problem. Sad

Are you sure the image is not the problem? I have had no issues with any image types.

You can upload all the files in the package or just upload the same ones that come with RN. Not all of them are needed but they will not hurt anything.

The image is the problem, that's what I said. When I load an .png then my site keeps loading and loading and it doesn't respond until a few minutes.

when I load a .jpg then it works properly but not with (png images) Shocked

You are not following me unicornio. My question was is the image itself messed up.

Give me a link to the image you are having trouble with and I will try it to see if the issue may be server configuration related or image related.

I can not tell u that because when I click on the icon to safe as a pdf then nothing happens. I get a blank page and the website gets stuck. When I make the story everything goes well and it shows the png image, it is just when I want to safe this document as a pdf.

I did not ask for an explanation, I asked for the image you are having trouble with so I can test it and see if that is the problem or not.

nuken, I am not sure the probel I originally reported is the same as what unicornio is getting.

I've just checked my admin preferences and there is no trailing / on the end of the site URL, so I am sure where the extra / is coming from, but if I cut and paste the filepath then it works without a problem. Confused

Are you using a windows server or apache? The reason I say that it that in the tcpdf_config.php, the file path is set in the very top. The slashes may be added there. It looks like this:

Code:




if (!defined('K_TCPDF_EXTERNAL_CONFIG')) {





   // DOCUMENT_ROOT fix for IIS Webserver


   if ((!isset($_SERVER['DOCUMENT_ROOT'])) OR (empty($_SERVER['DOCUMENT_ROOT']))) {


      if(isset($_SERVER['SCRIPT_FILENAME'])) {


         $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])));


      } elseif(isset($_SERVER['PATH_TRANSLATED'])) {


         $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr(str_replace('\\\\', '\\', $_SERVER['PATH_TRANSLATED']), 0, 0-strlen($_SERVER['PHP_SELF'])));


      } else {


         // define here your DOCUMENT_ROOT path if the previous fails (e.g. '/var/www')


         $_SERVER['DOCUMENT_ROOT'] = '/';


      }


   }





   // Automatic calculation for the following K_PATH_MAIN constant


   $k_path_main = str_replace( '\\', '/', realpath(substr(dirname(__FILE__), 0, 0-strlen('config'))));


   if (substr($k_path_main, -1) != '/') {


      $k_path_main .= '/';


   }

this maybe where the extra slassh is coming from.

It's an apache server.

Posted: Sun Jul 15, 2012 6:14 pm

The double slash issues is caused by both of these lines in printpdf.php

Code:




//$baseURL = getNukeURL();


//die($baseURL);


$htmlcontent2 = reltoabs($bodytext, $baseURL);

I would recommend:

Code:




global $nuke_config;


$baseURL = $nuke_config['nukeurl'];

That only fixes half the problem. The problem is that the reltoabs() function does not differentiate between links that start with a "/" or not. I could not reproduce the problem, but could see how this might cause it.

unicornio or jakec, in tcpdf.php search for the three lines of:

Code:




$imsize = @getimagesize($file);

Replace with:

Code:




$imsize = getimagesize($file);

Then see what errors are thrown.

Palbin I don't get any result. the site is getting loading all the time

I added a png images as I said above. This link is for nuken so he can see by himself.

Where is printpdf.php? I can't find it

This is the error I get, for nuken and palbin,

Code:

Gateway Time-out





The gateway did not receive a timely response from the upstream server or application.

Palbin, thankyou the first set of changes fixed the problem. Smile

Posted: Mon Jul 16, 2012 8:27 am

unicornio, printpdf.php file is located under the News module.

Posted: Mon Jul 16, 2012 10:21 am

Unfortunatetly it didn't work for me. Now it opens more faster but still blank page and says nothing.

This is what Palbin suggested to do:

Code:

// Arabic and English content


$htmlcontent2 = $bodytext;


global $nuke_config;


$baseURL = $nuke_config['nukeurl'];


//$baseURL = getNukeURL();


//die($baseURL);//Palbin where did you get this line I didn't have this one here. I just added now


$htmlcontent2 = reltoabs($bodytext, $baseURL);


$pdf->WriteHTML($htmlcontent2, true, 0, true, 0);

Posted: Mon Jul 16, 2012 11:04 am

unicornio, this is what my code now looks like:

Code:




// Arabic and English content


$htmlcontent2 = $bodytext;


//$baseURL = getNukeURL();


//$htmlcontent2 = reltoabs($bodytext, $baseURL);


global $nuke_config;


$baseURL = $nuke_config['nukeurl'];





$pdf->WriteHTML($htmlcontent2, true, 0, true, 0);

I still get a blank page doing this, anyway I will always upload jpg since png doesn't work with me. I guess I have to live with this problem.

Turn on error reporting and see what error is being generated.

Posted: Mon Jul 16, 2012 3:11 pm

I guess I should have been more clear. Especially since I left diagnostic code in my last post. What your code should look like now is this:

Code:




// Arabic and English content


$htmlcontent2 = $bodytext;


global $nuke_config;


$baseURL = $nuke_config['nukeurl']; 


$htmlcontent2 = reltoabs($bodytext, $baseURL);

jakec, glad your site works with while commenting out the reltoabs() function, but I am unsure of the consequences.

nuken, do you know of a better function for converting links instead of this reltoabs() which apparently comes from nukeSEO. We need something that differentiates between links that start with a / or not.

unicornio, your problem should access or server setup based, but could possibly could be caused by this issue. You need to turn on error reporting as nuken suggests. I know "we" have went over this many times before.
