Ok, I've found a workaround :

just disable "Prevent non-SEF variables from overwriting the parsed ones:".

It's just a workaround preventing Joomsef overriding correct vars with "cleaned" ones in sef.router.php into JRouterJoomsef::setRequestVars();

I hope it can help someone else.

For example if I'm calling this URL :

mywebsite.com/mysefurl?classe_energie_refrigerateur=A%2B%2B

getVar give me
classe_energie_refrigerateur=A

If Joomsef is disabled :
classe_energie_refrigerateur=A%2B%2B

WTF ????

Why does JoomSef filter my variables values ??? Why ???
Is there some antihack variable filtering ? How to disable it ?

Hi,

It seems there is a problem in Joomsef VM plugin in "Accept only filtered variables". (Manage extensions > Virtuemart > Variables filtering)

If I set :
Accept only filtered variables = yes
URLs that fail the variable filter test = Don't SEF variable

I get only non-sef url for virtuemart on frontend.

I need to not SEF all the variables not in "Don't SEF variable" because since I'm using Cherry picker CF, I can't know the list of variables it will use for filtering. (because the variables names are created from products customs fields which can change often)

Examples :
If no SEF, filtering URL should like this :
mywebsite.com/b?nombre_de_foyers_cuisini...mart_category_id=118

If SEF, it should like this : (but it don't)
mywebsite.com/b/electromenager/cuisson/c..._foyers_cuisiniere=3

If Accept only filtered variables = no I get :
mywebsite.com/b/electromenager/cuisson/cuisinieres-induction
(variable "nombre_de_foyers_cuisiniere" is just ignored)

If Accept only filtered variables = yes I get :
mywebsite.com/b?nombre_de_foyers_cuisini...mart_category_id=118
(It give me non SEF url, so I just want nombre_de_foyers_cuisiniere to be non SEF not the whole URL)

If I add "nombre_de_foyers_cuisiniere" to "Custom non-SEF variables" it work as expected. I get :
mywebsite.com/b/electromenager/cuisson/c..._foyers_cuisiniere=3

Unfortunately, I can't use "Custom non-SEF variables" because I'm using lot of customs fields changing often. I prefer just non SEF all unknown variables.

What am I doing wrong ?

Using :
Joomla! 2.5.22
VirtueMart 2.6.6 + Cherry picker
JoomSEF 4.5.2 (paying)
JoomSEF Virtuemart extension 3.0.22

Thank you for any help you can give me.

Best regards,
Yann
