struggling with taxonomies and taxonomy terms

Hello,

Thanks for the feedback!

The Taxonomy Terms field has 3 different “Return Format” settings possible:

• Terms names
• Terms ID
• Terms object

In all cases, it will return an array of Terms Names/ID/Object when using get_field('my_taxonomy_terms'), depending on the “Return Format” you selected in the Field Settings.

I’m not sure why you see the following:

So <?php echo (get_sub_field(‘category_tag_term’));?> returns “New Cat, Uncategorised” exactly what i want.

This is not normal, as get_field() and get_sub_field() will never change an array into a readable string format such as Item 1, Item 2.

However, the ACF functions the_field() and the_sub_field() which echo values has a builtin feature which convert array into a readable string such as this one.

In all cases, your code looks quite complexe to debug the issue. I would recommend to run a simple test to see which function return what:

<?php if(have_rows('my_flexible_content')): ?>
    <?php while(have_rows('my_flexible_content')): the_row(); ?>
    
        <?php if(get_row_layout() === 'post_grid'): ?>
        
            get_sub_field:
            <pre><?php print_r(get_sub_field('category_tag_term')); ?></pre>
        
            <hr/>

            the_sub_field:
            <pre><?php the_sub_field('category_tag_term'); ?></pre>
        
        <?php endif; ?>
    
    <?php endwhile; ?>
<?php endif; ?>

Hope it helps!

Have a nice day!

Regards.

Hi Konrad,

thank you so much for getting back to me.

I have implemented the simpler code you suggested

looks like i have used the incorrect function the explain my issue the_sub_field rather than get_sub_field.

thank you for explaining the difference.

what i need is for
“$categoryTagTerm” to be replaced by “array(‘New Cat, Uncategorised’)”

so that the chosen terms are placed with in the sub-array

the same way “$PostTypeChoice” becomes the chosen post-type ie “testimonials”
and
“$PostsPerPage” becomes the chosen number of post to display for example “4”

this

$postGridArgs = array(
                'post_type' => $PostTypeChoice,
                'posts_per_page' => $PostsPerPage,
                'post_status' => 'publish',
                'tax_query' => array(
                  array(
                       'taxonomy' => $categoryTag,
                       'field'    => 'name',
                       'terms'    => $categoryTagTerm,
                        'operator' => 'IN'
                        )
                )
        );

to this

$postGridArgs = array(
                'post_type' => 'testimonials',
                'posts_per_page' => '4',
                'post_status' => 'publish',
                'tax_query' => array(
                  array(
                       'taxonomy' => 'category',
                       'field'    => 'name',
                       'terms'    => array('New Cat, Uncategorised'),
                        'operator' => 'IN'
                        )
                )
        );

maybe there is a way to get the data i want, i assume its a string of values separated by commas, that creates the sub array?

I just got $PostTypeChoice and $PostsPerPage functioning so quick. Perhaps im approaching it all wrong, sorry im very new to this

Hello,

In order to turn an array into a string which use commas, I would recommend to check the implode() php function (see documentation).

However, note that’s not how the tax_query works, as it expect an array of terms ids/names/slugs if you want to query multiple terms, not an array with a string using commas. See WP_Query documentation & demo.

Notice the difference:

Array of values (good):

array('value1', 'value2')

Array with a string that use commas (not good):

array('value1, value2')

Hope it helps!

Have a nice day!

Regards.
