Hi

I use

<?php if ($choices = $wf->the->has("sc_fieldset_choices")) ?>
<?php foreach ($choices as $choice) : ?>
<?php echo $choice->sc_choice_01; ?>
<?php endforeach; ?>

in a template. Everything works fine. I only couldn’t find out how to shuffle the field values before looping them.

Thanks,
Marcel

Hi, so just to clarify, you’re trying to randomise the collection before output? There’s no built-in method to shuffle, but you could try this:

https://gist.github.com/traversal/727a30139046e962a426

This will get an array of the choices using the items method first, which is then passed into the PHP shuffle function.

Hi, thanks for your help. I tried but I get
Warning: Invalid argument supplied for foreach()

Hi, apologies for that, I wrote the code incorrectly, forgetting that shuffle doesn’t return an array. I’ve updated the gist now:

Let me know if that works.

Thanks!

MasterPress 1.3.6 is now available

Masterpress 1.3.6 is a compatibility release. It resolves an edge case with shared fieldsets not working for MySQL 8 when the fieldset is limited to more than 1 post type or taxonomy or excluding any post types or taxonomies.

Plugin Requirements

MasterPress requires a minimum of WordPress version 4.9, MySQL 5.6, and PHP version 5.6.20.

We also recommend that PHP is configured to use a memory limit of 64MB per request (128MB may be required for sites with higher complexity).

This plug-in is not compatible with the WordPress.com hosted service.
