Hi, i´m trying to put a pdf button, how can i get the id of the article i´m in?

How about using something like this: echo JRequest::getInt('id');

Thanks a lot...

Can you explain a little more about how/where to use echo JRequest::getInt('id'); so others can use it?
Please.

Simon

Thanks, unfortunate Ning strips out the code ;(
Can you mail to support at k2joom dot com I will take a look and see if I can get that working as well.

The thing i did is temporary, because what i did was changing the print button for a pdf button.
Later i want to have a new button but i don´t know how to do it yet.
ok.

Procedure:
1º - I edit the file C:\xampp\htdocs\joomla\components\com_k2\templates\default\item.php
2º - I change the original code:




item->printLink; ?>" onclick="window.print();return false;">



item->printLink; ?>" rel="{handler:'iframe',size:{x:900,y:500}}">





For this code:





&lang= ','mywindow','width=800,height=400'
);return false;">




With this code i open the file i want, in my case to make the pdf (oh, I´m using FPDF), then i get the id of the article and the language so i can use $_GET on the "FILE TO OPEN", and print categories and extrafields on the pdf.


I don´t know if it the best way, but is working. Hope this can help.

Sorry for the you can´t see the code, i will send it to you.

Simon, i´m always getting : Sorry, Your uploaded file type is not allowed

How can i send the file to you?

I have added you as a friend, when you accept, I will send you an email address so that you can email a zip file.

JRequest filters the POST and GET for security reasons and give it back. $_SERVER or $_POST was sended by formulars, get via URL, getint converts the value from string to an integer number. You can you use JRequest everywhere in PHP in a "mounted" Joomla, take a look on joomla docs.

So, i have replaced the print button code to link me to a file that makes the pdf. I´m using fpdf.
But i need to get a only some extra fields but using $this->item->extra_fields[1]->name;, how can i make my pdf file use this code?

You need the K2 article-id delivered via GET to your script. You can temporary write the data ($this->items->extra_fields) in a database table and read it in. Or you build a query and more to take it out of the K2 tables. This is not so easy. Or your send the fields data via GET, but then think about security and filter the data.

Temporary write the data ($this->items->extra_fields) in a database table and read it in. How so?

Can you use Yiota's example and try something like this
$yourvar = JRequest::getInt('id');
right where you are in the code and use it on the fly?

I changed the print button code on item.php on the directory \joomla\components\com_k2\templates\default.
Does this answer your question?

How can i be able to load and use the k2 classes inside my pdf file (external file)? If i could do this i woudn´t need to use GET or POST and make my website vulnerable
