Passing Template Variable Widgets to Snippets?

    I have a TV named MyTemplateVar with the HTML entities widget enabled. When I use this TV by itself, it parses htmlentities() properly. However, when I pass it to a Snippet, it disregards the Widget entirely.

    Is there a way to pass a Template Variable with Widgets to a Snippet?

    [!mySnippet? &sendString=`[*MyTemplateVar*]`!]

      No, because the snippet code fetches the raw value of the template variable. Well, I suppose the snippet in question could use a different API function to retrieve the formatted TV; the getTemplateVarOutput() function does that. http://wiki.modxcms.com/index.php/API:getTemplateVarOutput

      What you could do is create a snippet to replace the output widget (http://wiki.modxcms.com/index.php/Adding_TV_Widgets_without_hacking_the_core) then use that snippet (uncached) as the value for the parameter.

        [!mySnippet? &sendString=`[*MyTemplateVar*]`!]

        this should work
        first the tv is parsed and then its used in the snippet call.

          Hm. That’s correct. I was looking too deeply into the forest to see the tree!

            That’s my original code in the post above wink laugh The HTML entities values are not being returned properly.

            My [*MyTemplateVar*] has the content: " Some bad ! @ #* $( %) & and some more < > ";

            Then all [!mySnippet!] does is take the values and return them with html entities
            $output = "";

function htmlEncode($sendString){
$newVar = htmlentities($sendString);
return $newVar;
}
$output = htmlEncode($sendString);

return $output
