A beginning of solution to display fields in pdf was created by vlester

Hello,

I found a way to display fields and extra fields in the pdf but it's far to be perfect : there are three problems I can't solve.

You'll find below the "view.pdf.php" file I modified (inspired a lot by the file view.html.php).
In this example, I used the default template and I have only the field "category" displayed. As you could see in the pdf file enclosed, it indeed displays the category but also the subcategory and that is cool.

I have also tried with another template with all the fields displayed (created by, revised by, hits...) and all these fields are in the pdf. And so is the Select-FlexiContent-Item plugin (I haven't yet tried with other plugins).

So here are the problems:
1/ The CSS.
The pdf file doesn't get the css of the tempate so you might have to change the positions of the fields in your template and may be the css of the file item.php (for example add some "padding-top", some "<br>", etc. )
The <ul> and <li> become dashes in the pdf. I removed them from the file item.php but there are still 3 dashes at the top of the pdf and I don't know how to remove them.
You also can change these variables in librairies/joomla/document/pdf.php

Code:

var $_margin_header	= 10;
var $_margin_top	= 25;

To avoid the duplicate title, I also change this in the same file :

Code:

// Set PDF Header data
$pdf->setHeaderData('',0,'Mon site - http://www.monsite.fr');

2/ The second and bigger problem is the path of the images. I have errors with almost all the images of the page. For example (I use JComments):
TCPDF ERROR: [Image] No such file or directory in www.monsite.fr/components/com_jc ... avatar.png
or
TCPDF ERROR: [Image] No such file or directory in www.monsite.fr/index.php?option= ... t&ac=97789

(This file "no_avatar.png" exists and the pathway is ok).
To limit errors, I duplicated in the repertory "tcpdf" the repertories "components/com_flexicontent/Images" and templates/the_name_of_my_template/images, I also duplicated the repertory "M_images". These dupplications solved the errors with all the images of these repertories (icons mostly). But the problem is for the new images such like users avatars and Kaptcha images. I can't find how to remove the errors with these files.
(What is weird is that the images in the description field don't cause error.)

3/ The last problem is again with JComments
All the comments are displayed in the pdf file and I'd rather not. And finally, there is in the footer this ugly code I can't remove :

Code:

var jcomments=new JComments(12671, 
'com_flexicontent','http://localhost:8888/monsite/index.php?option=com_jcomments&tmpl=component'); 
jcomments.setList('comments-list');  
 
jcomments.setAntiCache(1,0,0);

I hope I was clear (sorry for my english). But the best way is to try by yourself this view.pdf.file
Please let me know if you could solve some of these issues.
Thanks a lot

Find below the code to put in the file view.pdf.php (components/com_flexicontent/views/item)
