Setting shop categories via page attributes

If I echo the $cats variable and then use that output by copying and pasting to the category filter, it works. It's just when I directly use the variable in code, it doesn't. What do you mean trim it down?

That's fine Drew, thanks for your help :-)

I'll take a look at this this evening.

I think the problem is that it's not recognising $cats as an array. Even if I use your solution above, it errors with:

Warning: Invalid argument supplied for foreach()

I cant seem to get this right Drew. Essentially, I would like to use whatever categories selected when editing/creating a page using page attributes to then display products by the categories selected.

Any help with this would be appreciated.

If I do this:

$cats = perch_page_attributes([
    'template' => 'shop_settings.html',
    'skip-template' => true,
], true);

print_r($cats);

It returns all of my page attributes:

Array ( [description] => Array ( [_flang] => plain [raw] => [processed] => ) [keywords] => Array ( [_flang] => plain [raw] => [processed] => ) [noindex] => [nofollow] => [nosnippet] => [gmaps] => [productsToDisplay] => Array ( [0] => 1 ) [navGroup] => repairs [pageID] => 5 [pageParentID] => 0 [pagePath] => /accessories.php [pageTitle] => Accessories [pageNavText] => Accessories [pageNew] => 0 [pageOrder] => 4 [pageDepth] => 1 [pageSortPath] => /accessories [pageTreePosition] => 000-004 [pageSubpageRoles] => [pageSubpagePath] => / [pageHidden] => 0 [pageNavOnly] => 0 [pageAccessTags] => [pageCreatorID] => 1 [pageModified] => 2016-08-20 21:50:03 [pageAttributes] => {"description":{"_flang":"plain","raw":"","processed":""},"keywords":{"_flang":"plain","raw":"","processed":""},"noindex":null,"nofollow":null,"nosnippet":null,"gmaps":null,"productsToDisplay":["1"],"navGroup":"repairs"} [pageAttributeTemplate] => default.html [pageTemplate] => [templateID] => 1 [pageSubpageTemplates] => [pageCollections] => [perch_description] => Array ( [_flang] => plain [raw] => [processed] => ) [perch_keywords] => Array ( [_flang] => plain [raw] => [processed] => ) [perch_noindex] => [perch_nofollow] => [perch_nosnippet] => [perch_gmaps] => [perch_productsToDisplay] => Array ( [0] => 1 ) [perch_navGroup] => repairs )

It's weird - if I use my original setup:

$cats = perch_page_attributes(array('template' => 'shop_settings.html'), true);

It returns exactly what I want:

array('products/accessories/')

...But I can also echo that value, which I shouldn't be able to do - it should give me a Notice: Array to string conversion error.

Even though it gives me what I want, it doesn't work unless I paste it directly into the perch_shop_products:

perch_shop_products([
    'template' => '/products/rhapso-product-list.html',
    'category' => array('products/accessories/')
]);

Sure:

<perch:categories id="productsToDisplay" set="products" label="Category" divider-before="Product categories to display" >
    <perch:before>array(</perch:before>'<perch:category id="catPath" />'<perch:if not-exists="perch_item_last">,</perch:if><perch:after>)</perch:after>
</perch:categories>

That worked brilliantly! Thanks very much Drew. It's funny, I tried explode before, but I used semi-colon instead of pipe but it didnt work. I must have done something wrong...

Thanks again.
