Displaying random images from a selected gallery

    In NGG prior to version 2.0, it was possible to display a limited number of random images from a specific gallery — like so:

    [random id="2" max="8"]

    This functionality does not seem to be supported by the 2.0+ version. It is now possible to select a random set of images, but they are selected from all galleries (attributes gallery_ids and source seem to be mutually exclusive):

    [ngg_images source="random"]

    The closest result I’ve got was this:

    [ngg_images gallery_ids="1" order_by="RAND()"]

    But it performs the random selection only once (after the post has been saved) and then caches it, so that the image set is not changing upon web page update. Besides, I don’t think that using SQL quantifiers in shortcodes is a good thing.

    Also, I cannot find any way for limiting the number of displayed images.

    So, again, the question is: how does one display a limited number of random images from a specific gallery?

    @zeyalabs – There are a few more parameters you might consider using with your shortcode …

    – images_per_page
    – disable_pagination (set to 1 to hide the pagination navigation if needed)

    Using the order_by="rand()" parameter/functionality is not really documented as it is not always supported by all web hosts. In some cases, it will simply not work at all.

    Please feel free to share any thoughts and suggestions on how we could improve this here: https://www.nextgen-gallery.com/feature-voting/

    Thanks!

    Thank you, Cais.

    I finally got it working and described the solution and the way to it.

    If I may: I perfectly understand the need of refactoring and even for introducing new interfaces, but given the popularity of NGG, Photocrati should provide complete legacy behavior compatibility, at least over a certain transition period. Feature voting is nice, but it should be used for new features, not for re-requesting old ones.

    Thanks again for the reply, and keep up the good work!

    @zeyalabs – Thanks for the update and sharing the link to how you sorted this out for your particular installation.

    The current NextGEN Gallery (2.0.x branch) has been out for just over a year now; and, yes, we did miss some NextGEN Legacy functionality in the branch and we have done our best to implement the more popular options as quickly as possible.

    This is the reason we suggest Feature Requests for these use-cases and “missed” options now as we are fairly far along the path going forward with our latest platform.

    – Cais.
