Answered Galleryitem &tpl parameter outputs an error on modx 2.2.7 - Is this a bug ?

The following code is used in my AdvSearch result template to display an image among other tvs :



I have to call a &tpl instead of using placeholders, due to some caching issue.

tplGalleryitem chunk is:


... and everything works fine, except that it outputs an error also and before all :

Notice: Undefined variable: output in C:\my\path\core\cache\includes\elements\modsnippet\9.include.cache.php on line 133

which is

if (empty($tpl)) return '';
$output .= $gallery->getChunk($tpl,$itemArray);
return $output;
}

( = line 128 here : https://github.com/splittingred/Gallery/blob/develop/core/components/gallery/elements/snippets/snippet.galleryitem.php )

Can someone have a look at this please ? I can't fix this for myself...

I'm still struggling with that issue.

This is my call


The Notice : Undefined variable appears when I set &toPlaceholders to 0, no matter if I add the &tpl property or not. The fact is that my tpl is called, and everything works fine... except that error that messes it all.

Here are some details on this "dot" operator: http://us2.php.net/manual/en/language.operators.string.php
And many other helpful things))

For this particular case you were absolutely right removing the dot.

Though it is better to add the check before the line causing this kind of errors:

haha.. actually i vaguely knew the dot has something to do with concatenation. Vaguely.

Anyway thanks for the tip I managed to ignore until today !
