Hi Frédéric,

that's very strange indeed - there's nothing wrong with the particular syntax you have used, as it's valid PHP and is supposed to work! I tested it on my test server and it didn't cause an error there.

One thing that you should do, however, is surround the right_META with quotes like this:

return "right_META";

Something that I have seen happen sometimes is that hidden characters can creep in when you are copying and pasting. You could try typing out the whole thing again instead of copying and pasting (lucky it's short).

If you can confirm that the error you reported ONLY occurs when you add the (!  ) syntax, then I will be very confused! Please let me know...

Cheers,
Stephen

I am *very* puzzled as to why this is happening for you. I have never seen an error like it. There's obviously something strange going on in your setup.

Perhaps you can avoid that syntax by changing the rule to the following:

if (

  $option != 'com_virtuemart'

  or JRequest::getVar('page') != 'shop.cart'

  or $Itemid != '2'

  or JRequest::getVar('zone_qty') != '1'

) return "right_META"; /* remplacer XXX par l'ID du module ou par sa position pour le faire apparaître */

Does this give you the same error?

Cheers,
Stephen

Hi thefbi,

the opposite of (x AND y AND z) is (!x OR !y OR !z).

So if you want to reverse the rule that you get from Advanced Debug mode, you have to change all the "==" to "!=" (as you have done), and change all the "and" to "or".

Therefore, I think this is what you want:

if (
  $option != 'com_quickform'
  or $view != 'quickmain'
  or $Itemid != '29'
  or JRequest::getVar('lang') != 'fr'
  or JRequest::getVar('forms') != '1'
  or JRequest::getVar('/quickmain/1_html') != ''
) return "left_FRED";

However, sometimes the Advanced Debug mode doesn't help you when you are trying to identify ONLY the front page of a component.

That's because often the inner pages of a component contain extra URL parameters, that the front page of the component does not have.

e.g. the front page of the component might be:

index.php?option=com_mycomponent&Itemid=100

and the inner pages might be:

index.php?option=com_mycomponent&Itemid=100&view=foobar&id=22

Therefore you can't uniquely identify the front page by looking for $option == com_mycomponent and $Itemid == 100, because that would select the inner page as well. The front page would have to be identified by having $option and $Itemid, but NOT having $view or $id.

I hope that might help to explain the situation... it might be easier if you can provide some more full URLs for some different pages in your component (or Advanced Debug output), or a link to your site if it's public.

Hope that helps,
Stephen

To combine those 2 rules, you can do it this way:

if  (
$option != 'com_virtuemart'
or ( JRequest::getVar('page') != 'checkout.index' and JRequest::getVar('page') != 'shop.cart' )
or $Itemid != '73'
or JRequest::getVar('/Voir-le-contenu-de-votre-panier_html') != '' /*!*/
) return 50;

In fact, I am pretty sure that you don't need the "Voir-le-contenu-de-votre-panier_html" line, so you should be able to use:

if  (
$option != 'com_virtuemart'
or ( JRequest::getVar('page') != 'checkout.index' and JRequest::getVar('page') != 'shop.cart' )
or $Itemid != '73'
) return 50;

Cheers,
Stephen
