Trying to add an extra text field to a taxonomy called Brands (product_brand) and getting this error with code on fresh install.
Fatal error: Cannot use object of type WP_Error as array in /home/mjackson/public_html/kinglouie.me/wp-content/themes/superstore/woocommerce/archive-brand.php on line 46
original code (line 46 is $term = $terms[0];)
<?php
global $post;
// load all 'category' terms for the post
$terms = get_the_terms($post->ID, 'brand');
// we will use the first term to load ACF data from
if( !empty($terms) )
{
$term = $terms[0];
$custom_field = get_field('contact_info', 'category_' . $term->term_id );
// do something with $custom_field
}
?>
Your help documents say that to Display a field in my Archive template all I need do is include this code
<p><?php the_field('field_name', 'category_7'); ?></p>
With my relevant data. However I can’t seem to get this to work either. Is it possible you could perhaps include a code snippet example for every setup that works on fresh, unmodified installs? Whether it be for adding WYSIWYG’s or Calender or, like in my case, a simple text field. This would certainly help me a lot just now and I suspect a few more out there.
Great looking new forum btw 🙂
@udapud,
The first issue is not ACF related (its throwing an error before getting to the ACF function). If your taxonomy slug is ‘product_brand’, your get_the_terms() function should be
$terms = get_the_terms($post->ID, "product_brand");
In addition to checking if the term array is empty, you should check for a WP error like:
if ( $terms && ! $terms->is_wp_error() ) { ... }
Since WP_Error is an object, it can’t be used as an array like in $term[0].
The second code posted should work on a fresh install, provided you have a field called “field_name” (with a value) for taxonomy “Category” for the term with ID 7.
Hi @udapud
Instead of using
‘
$term = $terms[0];
‘
Can you try
$term = array_pop($terms);
Does that fix the issue?

Ok, so I managed to get this code to work to get a specific taxonomy ID (so I know the system is working)
<p><?php // the_field('contact_info', 'product_brand_14'); ?></p>
But trying to get the same terms of the current Term ID being displayed, doesn't work however. (In my “archive-brands” template.) Even with array_pop.
<?php
global $post;
// load all 'category' terms for the post
$terms = get_the_terms($post->ID, "product_brand");
// we will use the first term to load ACF data from
if( !empty($terms) )
{
$term = array_pop($terms);
$custom_field = get_field('contact_info', 'category_' . $term->term_id );
// do something with $custom_field
}
?>
Thanks guys
Is ‘contact_info’ a field for Category terms or Brand terms? Based on the field that works, I’m guessing the latter, in which case you’ll need to change the 2nd get_field argument:
$custom_field = get_field('contact_info', 'product_brand_' . $term->term_id);
I’m afraid changing “category_” to “product_brand_” had no effect. It’s almost like that line has no way of getting the id of the current term. The address reads like this http://site/?product_brand=1st-call-mobility where “1st-call-mobility” is the term of the product_brand taxonomy.
“contact_info” is my ACF field slug, and “Brands” is a Custom taxonomy, whose slug is “product_brand”. Its a Woocommerce plugin, essentially for adding manufacturers to Woocommerce products.
I’ve tried printing this code before and it just wasn’t picking up the terms custom field in the print either.
Do I perhaps need to define “$custom_field” somewhere?
No matter I fixed it. The problem was with “get_field” I replaced it with “the_field”
<?php
global $post;
// load all 'category' terms for the post
$terms = get_the_terms($post->ID, "product_brand");
// we will use the first term to load ACF data from
if( !empty($terms) )
{
$term = array_pop($terms);
$custom_field = the_field('contact_info', 'product_brand_' . $term->term_id);
// do something with $custom_field
}
?>
By the way chaps thanks incredibly for the help, I was ready to gauge out my eyes. 🙂
