Hi Coen, I can't get this code to work: "Catchable fatal error: Object of class WP_Error could not be converted to string in...." Any ideas?

Have you inserted your attribute name in the variable on line 15?

Thanks for the reply. Yep, sure have...

I think the error is caused by products not containing any categories. Added a check for an empty array in the latest revision.

Still no luck I'm afraid. Same error.

Updated again, can you try again?

Thanks again Coen, but same error: "Catchable fatal error: Object of class WP_Error could not be converted to string in..."
Could you explain what this predefined $brand is and how Woo uses it? I'll try and help trouble shoot if I can...

And you are absolutely sure that the name you enter in line 15 is the exact name of the attribute? You could for example use 'product_cat' to show the product categories linked to it.

$brand is not a predefined variable, it is used from another example. I've updated it to a standardized version, using local $terms and $term variables.

My apologies Coen, my stupidity: I wasn't giving the "pa_" prefix to the attribute name!!!! Sorry, and thanks!

Hi Coen,

I'd have a question regarding this: With slight code changes, would it also be possible showing the attribute values (e.g. for attribute pa_brand - value "Calvin Klein") beneath the product images in the product categories? Basically what I would like to do is add additional information next to my product images, so users can already see certain specifications of my items, before having to go to the single product page.

Thanks a lot,
Rich

@richangel Yes, you would basically be using another hook, like 'woocommerce_after_shop_loop_item_title' or 'woocommerce_after_shop_loop_item' for example. The rest of the code doesn't really change much.

Great, thanks a lot for your answer, I will give it a shot!

Rich

Thanks @coenjacobs

I added the code but it only shows one (the first one) $term->name

For some reason the loop is not working. Do you have any suggestion? Thanks!

I'm trying to show all terms for an attribute in a list in sidebar, so I think the problem is that $post->ID is for a specific Post. I need to call the entire list (values for the specific attribute)... Any suggestions? Thnaks!

I created a Folder, and placed the php in a .txt file from above, change line 15 to "pa_brand" "pa_popular-designs"

I don't get an error, but nothing happens, no attributes showing.

Does this code still work with latest woo & wp? would love to use it

Hi Coen
I'm trying to make this into a shortcode, so that if I put it on a page a list of the specified product attributes will show up as links. Is that possible?>
Thanks

Hi Coen
I have the same problem - no error but nothing showing.
Is there something I need to change for more recent versions of woocommerce and WP?
Thanks!

Nope, this code works fine in the latest versions of WooCommerce and WordPress.

Make sure you get the attribute slugs exactly right (including the pa_ prefix) and it will work, just tested it.

Hi,

I confirm, the code works with pa in the prefix of the attributes.
But
How to display on one single line one attribute and then a second line a second attribute
(with the automatic loop)

Hello, this works just fine, but after I click the attribute it shows a white page. I did this stuff here http://wcdocs.woothemes.com/codex/extending/using-custom-attributes-in-menus/ but still not working.

Hi, this is a nifty little "plugin" and it's working flawlessly.

I'm trying to remove the attribute name from the add_action but I've tried everything and it gives me all kinds of different errors. Are there a easy way to change this. Ex.: Buttonsize 3/4 should become Button is 3/4. I would still like the slug to be buttonsize.

Thanks in advance and if this isn't possible it's still a rather nice piece of code :-D

Best regards
Valdimarsson

Well, having not to much PHP-experiance, I would like to know where to put this plugin? Functions.php? A .php-file for by itself? Or where?

I am trying to put an attribute with the property fx: Condition: Used, right next to the SKU in the product_meta div..

Help would be greatfully appreciated!

I can't get this to work. If my attribute name is 'format', I put pa_format (format being the name of the attribute) and they don't show up. Should it be '<pa_format>' or 'pa_format' or pa_format? Neither seem to work. Thanks!

Hello,
From last update of Woocommerce I have label "Product" in front of every attribute name. Please how could I remove it?
Thanks

Change hook
add_action( 'woocommerce_shop_loop_item_title', 'cj_show_attribute_links' );

I want to add Link in attributes Value and want to display Link in attributes Value.
