Ça fait longtemps que le gabarit des news contient la variable canonical par défaut {assign var='canonical' value=$entry->canonical} et {process_pagedata} ne sert plus à rien. La partie concernant ce sujet est obsolète (elle date de 5 ans...).
Pour la V2, les variables des sous-gabarits ne seront plus disponibles dans les gabarits parents (dernière version stable de Smarty). Pour que cela soit à nouveau possible, il faut ajouter scope=global lors de l'assignation de la variable (voir le lien vers le post de Calguy au sujet de l'avancement de la V2 que tu nous as donné aujourd'hui ici

).Citation :In CMSMS 1.x it was assumed and documented that all smarty variables were available at all time, and never disappeared. If you created a variable (lets say 'page_title' in a module template called from the {content} tag that was called from within the </__body> section of your page template, that variable {$page_title} would be available within the <head> section of your page template.
Unfortunately, that is no longer true without explicit action by you. In smarty (now that CMSMS is using an un-modified version of Smarty), sub templates create their own scope. And there is a hierarchy of templates. Variables are copied from parent scopes into child scopes, but are not copied from the child to the parent. Making a smarty variable persistent across multiple scopes requires explicit action by the site developer (specifically you).
Fortunately, it is relatively easy to copy a local variable in a sub template, into a global variable for use in the parent, or other peer templates. And we have added a new smarty plugin to the core to help even more.
If you remember the stock News detail template there was a line such as this:
Code:
{assign var='canonical' value=$entry->canonical}
That created a smarty variable called 'canonical' that was then used in the <head> portion of the page template to create the <link rel="canonical"> tag.
Because of the new smarty scoping methodology, that syntax now looks like this:
Code:
{assign var='canonical' value=$entry->canonical scope=global}
Additionally, the {share_data} plugin will allow you to specify numerous local variables that should be copied to the local scope. i.e:
Code:
{share_data scope=global vars='page_title,canonical,page_description'}
CMSMS uses smarty sub-templates extensively. The most obvious ones are the {content} tags, module templates, like {News}, {Search}, or {Navigator}. However the three portions of the page template (above the HTML tag, from </__body> down, and the head section) are each individual sub templates. Thus, without explicit action variables created in the top section are now not available in the body.
