Getting started with Galleria - got an error...

Tiggrrr42 · 2018-01-16 04:55:52

Backlight updated to latest release.

Publisher updated.

Created new Galleria template.

Created a new album and associated it with the template.

Published album and get this message on the page:

Something went wrong
Unexpected error: Undefined variable: thumbnails in galleria-pangolin.php on line 45

Album is at:

Testing Galleria

I've enabled guest credentials:

User: guest

Password: MtEfsGCZ8zm

Any suggestions?

(Enabling FTP would be more... interesting due to the way I've locked the server down...)

I don't see the error message on that page. But I don't see the slideshow either, even though it's in the page's source code.

Since the error implied thumbnails, have you tried using another thumbnail setting? I've tried them all during testing and they all worked for me.

rod barbee · 2018-01-16 06:54:33

there's a question mark in one of your photo captions. Try removing that and see if it helps.

Daniel Leu · 2018-01-16 07:17:46

That's a strange error; something Matt will have to look at. As Rod suggested, I would try different thumbnails settings.

Oh, which setting did you use that created this error?

rod barbee · 2018-01-16 08:41:19

never mind about the question mark. I just added one to a caption in a Galleria show and it didn't break it.

rod barbee · 2018-01-16 08:57:16

You might try clearing template cache as well as creating a brand new template. Looking at your template, I see you're using carousel. In the page source code I see this:

Galleria.run('.galleria', {
  autoplay: false,
  carousel : ,
  dataSource: data,
  imageCrop: true,
  fullscreenCrop: false,
  maxScaleRatio: undefined,
  showCounter: true,
  showInfo: true,
  thumbCrop: false,
  thumbnails: });

But in my slideshow, also using carousel, I get this:

Galleria.run('.galleria', {
  autoplay: 5000,
  carousel : true,
  dataSource: data,
  imageCrop: false,
  fullscreenCrop: false,
  maxScaleRatio: 1,
  showCounter: false,
  showInfo: true,
  thumbCrop: false,
  thumbnails: 'lazy'});

for some reason, carousel and thumbnails aren't getting any values attached to them. So maybe a new template?

Matthew · 2018-01-16 09:23:06

That's weird. Conditions are set up for every choice, and should be 'disabled' by default, rendering 'false' in both places. Try choosing any thumbnail type to force a change and save it, then switch back to your preferred choice.

Tiggrrr42 · 2018-01-16 15:36:55

Thanks for the replies - I'll have another try and report back later

speacock110 · 2018-01-16 18:52:11

I am having exactly the same problem. I have completly republished the images, inc. new images. Changed as many settings in the template and I still get the same error in red atb the bottom of the screen.

Matthew · 2018-01-16 20:28:49

Utterly bizarre. Sorry for the inconvenience, but we've had no luck at all reproducing this issue on our side. Try this, though.

Open the file /backlight/modules/pangolin-galleria/dynamic/js/galleria-pangolin.php in an editor.

Find this, near the top:

  if ( $model->value('galleria.thumbnails') == 'disabled' ) {
    $thumbnails = 'false';
    $carousel = 'false';
  } elseif ( $model->value('galleria.thumbnails') == 'carousel' ) {
    $thumbnails = '\'lazy\'';
    $carousel = 'true';
  } elseif ( $model->value('galleria.thumbnails') == 'empty' ) {
    $thumbnails = '\'empty\'';
    $carousel = 'true';
  } elseif ( $model->value('galleria.thumbnails') == 'pallet' ) {
    $thumbnails = '\'lazy\'';
    $carousel = 'false';
  }

Replace with this:

  if ( $model->value('galleria.thumbnails') == 'carousel' ) {
    $thumbnails = '\'lazy\'';
    $carousel = 'true';
  } elseif ( $model->value('galleria.thumbnails') == 'empty' ) {
    $thumbnails = '\'empty\'';
    $carousel = 'true';
  } elseif ( $model->value('galleria.thumbnails') == 'pallet' ) {
    $thumbnails = '\'lazy\'';
    $carousel = 'false';
  } else {
    $thumbnails = 'false';
    $carousel = 'false';
  }

Have you tried Matt’s potential fix?

simkense · 2018-01-17 00:37:30

I just tried, but still the same problem. (I also cleared the cache)

rod barbee · 2018-01-17 01:33:08

can you post a link to a galleria album that's not working. It'll give Matt another data point

rod barbee · 2018-01-17 01:38:12

another question: did you update the Publisher Lightroom plug-in?

speacock110 · 2018-01-17 03:00:27

Also tried the fix and it did not work. The publisher plugin is the latest. Also re copied just to check prior to republishing. Sorry cannot provide a link as my workflow involves a local website prior to uploading in case of issues like this

The error is now on line 35

Did you clear the template cache after modifying the file http://yourdomain.com/backlight/designer/?a=clear_cache

simkense · 2018-01-17 03:32:14

I updated the LR plugin.

speacock110 · 2018-01-17 03:37:21

cleared the cache, it has become an automatic process these days.

Could you post the entire error message please?

speacock110 · 2018-01-17 05:18:27

Exactly as previously posted at the start of this post but 45 replaced with 35
Unexpected error: Undefined variable: thumbnails in galleria-pangolin.php on line 35

Tiggrrr42 · 2018-01-17 05:54:46

Hmmmm

Tried the edit, cleared cache, republished.

This time I don't get the red error message, but I don't get a gallery either!

New test album here

speacock110 · 2018-01-17 05:57:40

I also noticed the red error message sometimes there and sometimes not. Usually after i have either logged in or logged out of Backlight admin, cleared the cache or closed then reopened the browser. Tried to find a reproducable patttern but as of yet have not.

Daniel Leu · 2018-01-17 07:06:16

I think I found the culprit: Open the file /backlight/modules/pangolin-galleria/dynamic/js/galleria-pangolin.php in an editor and change line 14 from

<?

to

<?php

Then clear the template cache (http://yourdomain.com/backlight/designer/?a=clear_cache).

It seems like different opening and closing tags for php can be used, but only if the platform is configured for it. It looks like this was the case for all beta testers

Tiggrrr42 · 2018-01-17 07:14:47

Ahhh, yes! I now have a working test.

Good catch - my installation of PHP7 doesn't have short tags enabled, which would account for the borkage.

Now all I need is the time to configure it!

Many thanks, Daniel
