tcpdf is trying to write in /sites/all/libraries/tcpdf/cache

Your right, we need to change this.

I have never give the system the option to right to those directories and it works. I depends on the environment (Image Processing Library etc.).

sub

Relevant:
http://tcpdf.git.sourceforge.net/git/gitweb.cgi?p=tcpdf/tcpdf;f=config/t...

Came across this and just wanted to share where the cache path and all that is set :)

Just in case somebody can't get it to work (thanks to patcon for pointing out the solution):
1. Create a folder named tmp in your_drupal_site/sites/default/files
2. Make it writable by the server
3. Open the file your_drupal_site/sites/all/libraries/tcpdf/config/tcpdf_config.php and change this:

/**
 * cache directory for temporary files (full path)
 */
define ('K_PATH_CACHE', K_PATH_MAIN.'cache/');

/**
 * cache directory for temporary files (url path)
 */
define ('K_PATH_URL_CACHE', K_PATH_URL.'cache/');

to this:

/**
 * cache directory for temporary files (full path)
 */
define ('K_PATH_CACHE', K_PATH_MAIN.'../../../default/files/tmp/');

/**
 * cache directory for temporary files (url path)
 */
define ('K_PATH_URL_CACHE', K_PATH_URL.'../../../default/files/tmp/');

Of course you can use any name other than tmp for your folder.

I got this error after upgrading from Drupal 7.10 to Drupal 7.14

I copied the origional tcpdf and fpdi libraries I used on the Drupal 7.10 platform and got the above error...

When I install a new tcpdf library downloaded from the site the error goes away but none of the text is displayed in pdf only the images...

I have two sites on this platform both using views_pdf so the above solution will only solve one sites issues...

What would the best versions of tcpdf and fpdi to use in conjunction with this module?

Upgrading 7.12 to 7.14 (important Security Update) just caused my Views PDF View with images to render a similar error as well:

Warning: fclose() expects parameter 1 to be resource, boolean given in TCPDF->Image() (line 7525 of /var/www/html/sites/all/libraries/tcpdf/tcpdf.php).
Warning: fwrite() expects parameter 1 to be resource, boolean given in TCPDF->Image() (line 7524 of /var/www/html/sites/all/libraries/tcpdf/tcpdf.php).

^ I get this for every node in the view

Line 7523 starts on $fp line:

					if ($imgdata !== FALSE) {
						// copy image to cache
						$file = K_PATH_CACHE.'img_'.md5($imgdata);
						$fp = fopen($file, 'w');
						fwrite($fp, $imgdata);
						fclose($fp);
						unset($imgdata);
						$cached_file = true;
						$imsize = @getimagesize($file);
						if ($imsize === FALSE) {
							unlink($file);
							$cached_file = false;
						}
					}

On a side note, I would appreciate some help on this as this is on a client's production website who will be needing this view in the next couple weeks. I'll experiment with it but have never had to fix a library related issue in the past.

I was able to temporarily fix my specific issue by changing $diskcache to true on line 1213:

protected $diskcache = true;

I still get the errors because the "/var/www/html/sites/all/libraries/tcpdf/cache" directory isn't writable for this script. Gotta contact my other webmaster to see how he set up the privileges. If I can suppress the errors, I will let you know here.

Hi ownage,

Just a heads up, but that's a totally different error from the original, and so probably belongs in another new issue. I'd open a new one instead of posting here :)

Same issue here

TCPDF ERROR: [Image] Unable to get image: /web/libraries/tcpdf//sites/default/files/styles/exhibitor_logo_140/adaptive-image/public/E-Boost%20logo.png

Can't we just change the directory?

Glenn

Same issue here. I think it's time to change cache directory. Print, email and and PDF versions module already do that - TCPDF allows to set custom cache directory with K_TCPDF_EXTERNAL_CONFIG setting. I will try to create a patch for that.

Thanks for trying to create a patch!

Hello, Simon Georges!

I have created a patch for custom cache directory against 7.x - 1.x. I took idea from Printer, email and PDF versions (see here http://drupalcode.org/project/print.git/blob/refs/heads/7.x-1.x:/print_p...) Print module has separate setting for that, my patch at the moment just change the TCPDF cache directory so maybe that should be improved.

Hey, thanks!

Can somebody else review it, so we can confirm it works on several server configurations?

The patch from #12 worked for me.

Thanks!

I can confirm that patch #12 applied to 7.x-1.x-dev (2013-Mar-09) solved the issue for me.

I had all sort of error messages (see below) before that and no images.

Ok, committed, thanks for the patch and the reviews!

Exist a patch to handle this issues and others. Please see #2032189: Multiple issue fixing in a single patch and review others issues patch.

This is RTBC, and ready to apply.

This patch has already been committed and pushed (just minutes before your comment, I suppose it's just damn bad luck on the timing on my part).

Ummmm yeah I'll check again the full patch and handle the others fixings.
