Multiple NextGen Gallery Albums per page

  • (This was previously reported privately to Imagely support, but nonetheless, they requested this be publicly posted, so it is being posted here.)

    So, after getting the style we wanted… we found a couple of bugs.

    One is minor, and should be relatively easy to fix… if you click on one of the galleries in the album, when the page reloads, it sends you to the top of the page. This is jarring for the user.

    I think generating an <a name="nggallery-${idx} /> tag just before the gallery/album HTML itself, and ensuring every gallery link is suffixed with #nggallery-${idx}, would solve this.

    The second one though, is much more serious. For this, I quickly slapped together a demonstration. This is a bare-bones WordPress install, done yesterday morning, with no themes or plug-ins except the Imagely theme, and the NextGen Gallery, NextGen PRO plug-ins.

    https://albumtest.vk4msl.com/

    I’ve created four galleries, stored in two albums. (Note, the photos are not terribly high resolution — I use these for slow-scan television on amateur radio, where the “standard” is 320×240px.)

    Now, this page has two “album” blocks on it:

    • Animals
    • Landscapes

    For the sake of testing, I selected “Pro Film” style for the galleries on this page.

    Animals has two galleries: “Sam the cat” and “Wildlife”. These function just fine. No issues. Aside from the issue above where it sends you to the top of the page, they work well.

    The second one has two other galleries: “St. Helena Island” and “Snowy Mountains”. Its behaviour, despite an identical configuration (aside from selected album), is very different.

    These work, but when you “enter” one of these galleries, the gallery appears under the heading “Animals”.

    Now… on the actual site we want to use the “Pro Tile” gallery style. I made a second page showing what happens when you do this.

    https://albumtest.vk4msl.com/index.php/pro-tile-gallery-testing/

    Same set-up, just I changed the gallery style in each album block.

    The “Animals” galleries, work as they should.? Pro-tile works great despite all of these being low-resolution 4:3 aspect ratio photos.

    The “Landscapes” galleries break rather badly.? Enter one of those, and all galleries disappear.

    There’s no browser errors, this appears to be an issue in the PHP back-end code.? I’ve attached the Apache web server error log.

    My hunch is this:

    – when a user clicks on a gallery, they are taken to a URI constructed from this template: ${PAGE_URI}/nggallery/${GALLERY_SLUG} (where ${PAGE_URI} is the URI of the page, and ${GALLERY_SLUG} is the gallery title with all non-URL-safe characters substituted).
    – the PHP code sees the ‘nggallery’ sub-path in the URI… the *first* NGGallery block tries to interpret it.
    – First NGGallery block looks through its galleries (from the “Animals” album), can’t find one with a matching slug, silently fails.
    – Due to state corruption by the first NGGallery block, the second NGGallery also fails.

    “Pro Film” seems to almost work fine… it seems the first NGGallery block is interpreting the query.? “Pro Tile” appears to not handle this as gracefully (maybe some shared state?) and so when the first instance fails, it leaves variables in a bad state that means all subsequent NGGallery blocks fail to render properly.

    I’ve attached the Apache web server error log.

    Imagely support, see the email I sent yesterday for aforementioned log. I won’t post it on this forum for security reasons, but you should already have it in your support system.

    Is there something I’ve missed in the above? Or did support give me a bum steer and really this should have been reported to Imagely support (as it was originally before they sent me here)?

    It’s worth noting that NextGen PRO is involved here, as was spelt out in this post and the original email, which was purchased under an apparent “lifetime” support.

    Said site it was purchased for has been live less than a month, so if a “lifetime” support really does expire that quickly, then ALL Imagely customers should be made aware of that, as this is not normally what a “reasonable person” would define as “lifetime”.

    So, nothing heard… further information incoming. If this is the wrong, or irrelevant information, then PLEASE TELL ME… while I might wear a pointy hat, I’m no wizard, and definitely cannot read minds.

    To describe in pictures, what I am seeing… because apparently this silence seems to indicate a complete lack of understanding…

    Go to https://albumtest.vk4msl.com/index.php/pro-tile-gallery-testing/ as mentioned, there are two albums.

    On my machine, it looks like this: https://albumtest.vk4msl.com/bug/pro-tile-gallery-albums.png quite clean, well presented. It is this presentation we want for this page: https://imagery-captivation.com/photography/sports/ — so far, no issues.

    Click on one of the galleries on the first album, I see this when I click “Wildlife”: https://albumtest.vk4msl.com/bug/pro-tile-gallery-wildlife-gallery.png

    Two issues I see here:

    • the first album instance does exactly what it’s supposed to, we see the “Wildlife” gallery as expected
    • the second album instance is now completely blank — why? It should be showing the two landscape galleries…?

    Now, go back and try clicking on one of the landscape galleries. I get this: https://albumtest.vk4msl.com/bug/pro-tile-gallery-landscapes.png

    • The first album is now blank. Why? We didn’t touch it, it should be showing its two galleries (“Sam the cat” and “Wildlife”) like nothing happened.
    • The second album is also blank. Why? It should have the photos of the gallery I clicked on. Why is it blank?

    How do we fix this? We’d like to get this working so we can roll it out on the production site. I’ve set this site up temporarily while we troubleshoot the issue… but so far it seems I’m going to have to trawl through the PHP code. That is not paid support as I know it.
