Assigning {asign} textsnippet containing HTML Content throws SmartyCompilerException

Shopware 5 Themes & Design

Dear Shopware Community,

i have a Problem with encodings in Shopware assigning a text snippet in the template.

{assign var='topBarPromoLinkText' value="{s name="MetaHeaderLeftLinkText__BR2017" namespace="topbarNavigation"}{/s}"}

I know that this is no best practice but we need to check the presence of a variable via an if condition so i need to assign it.

{if !empty($topBarPromoLink)}
   
      
   
{/if}

If i put a Quote in the snippet i get SmartyCompilerException:

Can anyone help me solve this so no matter what the user inserts in to the snippet in the backend the frontend just displays it as normal text!?

You wrote

{assign var='xxx' value="{s name="...}

So the parameter named value contains {s name= .
Everything after the second double quotation mark is intepreted as a next parameter/command/… .

Problem: You can’t use " inside of ". How should smarty know where your parameter ends? It just chooses the next occurence of " as the end marker of the parameter’s value.

Solution: Just use single quotation marks for the second parameter as you did for the first one.

Best regards

Thank you very much for your answer. But this does not solve the problem. The code still breaks. I guess it has to do with the {asign} tag… could that be the case?

Can you show us your updated code?

{assign var="topBarPromoLinkText" value="{s name='MetaHeaderLeftLinkText__BR2017' namespace='topbarNavigation'}{/s}"}

Does the snippet MetaHeaderLeftLinkText__BR2017 contain double quotation marks (")?

If so, I think there’s no easy solution except using PHP and assign the variable there.

yes thats true. it contains double quotes. we must asume that the editor puts in quotes.

If you tell us what you want to achieve, maybe we can find a different solution?

Why do you have to assign it to a variable anyways? Can’t you just use the snippet directly?

Ok, i need to asign the variable to the view because we use an if condition to check which fields are filled to decide what code to render.

If there was another way to check empty of a snippet directly, maybe that could help. 

{if !empty($topBarPromoImageLink)}
   {if !empty($topBarPromoLink)}
      
         
      
   {else}
      
   {/if}
{elseif !empty($topBarPromoLinkText)}
   {if !empty($topBarPromoLink)}
      
         {$topBarPromoLinkText}
      
   {else}
      {$topBarPromoLinkText}
   {/if}
{/if}

Excuse the wrong formatting but the code element does it automatically here.

 

Best regards,

Oliver

anyone an idea?

I’d suggest using a plugin like this:
(Comments are included)

 'onPostDispatch'

            // 2. Maybe you also need the variable inside a widget module
            // if so uncomment the following line
            //'Enlight_Controller_Action_PostDispatchSecure_Frontend' => 'onPostDispatch'
        ];
    }

    /**
     * The event listener function 
     */
    public function onPostDispatch(\Enlight_Controller_ActionEventArgs $args)
    {
        /** @var \Enlight_Controller_Action $controller */
        $controller = $args->get('subject');
        $view = $controller->View(); // 3. get the view object

        $snippets = Shopware()->Container()->get('snippets'); // 4. get the snippets object from the DI

        // 5. select your snippet
        $metaHeaderLeftLinkText = $snippets->getNamespace('topbarNavigation')->get('MetaHeaderLeftLinkText__BR2017');

        // 6. Assign it a a tpl variable called topBarPromoLinkText
        $view->assign('topBarPromoLinkText', $metaHeaderLeftLinkText);
    }
}

Just put this file at custom/plugins/MrMoreePlugin/MrMoreePlugin.php , install it, activate it and clear the cache. Then you should have a new frontend variable called topBarPromoLinkText containing the snippets text. This code is untested.
