And the handler was called using the line....

http://www.thierrybazzanella.com/wakka.php?wiki=Accueil/raw&pdf=1

and here are the instructions....

"Elle est téléchargeable vers http://www.fpdf.org

INSTALLATION:

Téléchargez la librairie fpdf et dézippez-là dans un dossier.
Mettez le fichier fpdf.php et le dossier font à la racine de votre wiki.
Téléchargez le fichier handlers/page/raw.php livré ICI,éditez le, et définissez en absolu le chemin du dossier font de votre arborescence fichier.
Ligne 25 : define('FPDF_FONTPATH','/home/www/users/thierrybazzanella/www/html/font/');

Remplacer ce fichier par le vôtre en lieu et place. "

that were there.

Thanks, Mike. That looks nicely implemented - though I don't see where the page is turned into HTML first; my guess is you need to run it through the formatter first (it looks like it's transforming HTML tags - not Wiki-markup tags - for printing as PDF). But it shouldn't be too hard to make it work. --JavaWoman

Installing Fpdf

1. download the fpdf-package and put it's content into 3rdparty/plugins/fpdf

3. Change the following thing in wikka.php
a) no computing time (i.e. after line 385 if you are using 1.1.6.5):
change

if (!preg_match("/(xml|raw|mm)$/", $method))

if (!preg_match("/(xml|raw|mm|pdf)$/", $method))

b) we want no header and footer, therefore change in libs/Wakka.class.php
add after the following code (i.e. after line 1750 if you are using 1.1.6.5)

// raw page handler
elseif ($this->method == "raw")
{
header("Content-type: text/plain");
print($this->Method($this->method));
}

//page to pdf - handler
elseif ($this->method == "pdf")
{
print($this->Method($this->method));
}

4. Notice that the real work has only begun ;)
