Hello, i added custom filed for category, called cat_thumbnail_image i want to show my category.php child category information with thumbnail images. i already search in this forum and got many post like it tried almost all the way but failed to get result. i am sure i am missing something.
here is code
Return Value is Image URL
<?php
$args = array('child_of' => 43);
$categories = get_categories( $args );
foreach($categories as $category)
$image = get_image('product_categories_'.$category->term_id);
{
echo '<figure class="snip0015"><img src="'.$image['url'].'" alt="'.$image['alt'].'" /><h2>'. $category->name.'</h2>';
echo '<div> Description:'. $category->description . '</div>';
echo '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '></a></figcaption></figure>';
}
?>
it show me Fatal error: Call to undefined function get_image() …..
i tried
$image=get_image('cat_thumbnail_image'.$category->term_id); >> error showing
and
$image=get_field('cat_thumbnail_image', 'category_'.$category->term_id); >> image filed empty
and
$image=get_field('cat_thumbnail_image', $category); >> image filed empty
Hi @pagol
Could you please tell me where did you add the custom field? Was it the product category or the normal post category?
ACF doesn’t have a function called get_image(), that’s why you got the error message. Could you please try to set the ID manually like below?
$image = get_field('cat_thumbnail_image', 'category_99');
print_r($image);
Where ’99’ is the ID of the category. If it works, then there’s something wrong with your $category variable.
Thanks 🙂
This is filed section screenshot
This is category section screenshot
i can not put static category id. because under my category i have more sub category, in my query i wan to show all child category title, description and image
Hi @pagol
Could you please test the following code for me?
$image = get_field('cat_thumbnail_image', 'category_99');
echo <pre>;
echo "Image field value:";
var_dump($image);
echo "Category value:";
var_dump($category);
echo </pre>;
Where ’99’ is the ID of the category. Yes, please set the ID manually in this test so we know if the get_field() function returns the value or not.
Thanks 🙂
it show long dump code i just paste part
<?php
$args = array('child_of' => 43);
$categories = get_categories( $args );
foreach($categories as $category)
{
$image = get_field('cat_thumbnail_image', '47');
echo '<pre>';
echo "Image field value:";
var_dump($image);
echo "Category value:";
var_dump($category);
echo '</pre>';
}
?>
47 is my one of category id.
result bellow
Image field value:NULL Category value:object(WP_Term)#399 (17) { ["term_id"]=> int(47) ["name"]=> string(7) "Banners" ["slug"]=> string(14) "banner-designs" ["term_group"]=> int(0) ["term_taxonomy_id"]=> int(47) ["taxonomy"]=> string(8) "category" ["description"]=> string(124) "We design and print custom size banners for all industries including motorsports, transportation, special events & more." ["parent"]=>
Hi @pagol
How about this one?
$image = get_field('cat_thumbnail_image', $category->taxonomy . '_' . $category->term_id );
echo '<pre>';
echo "Image field value:";
var_dump($image);
echo '</pre>';
This page should give you more idea about it: https://www.advancedcustomfields.com/resources/get-values-from-a-taxonomy-term/.
Thanks!
COOL… this is work. 🙂 thanks you so much for quick and great support ..
now i am facing one small issue. bellow is my code. it is working fine. i get proper value but issue i want only active category value. bellow code show all category image loop
<?php
$args = array('child_of' => 67);
$categories = get_categories( $args );
foreach($categories as $category)
{
$image = get_field('cat_thumbnail_image', $category->taxonomy . '_' . $category->term_id );
echo '<div class="test">'.$image.'</div>';
}
?>
Hi @pagol
Could you please tell me what did you mean by “only active category value”? Did you mean only show categories that have the “cat_thumbnail_image” field value? If that’s the case, I believe you can do it like this:
foreach($categories as $category){
$image = get_field('cat_thumbnail_image', $category->taxonomy . '_' . $category->term_id );
// Check if the image exists
if( $image ){
echo '<div class="test">'.$image.'</div>';
}
}
If that is not what you want, could you please explain it to me again?
Thanks 🙂
Thanks for reply.
actually before code was loop. meaning all child category image will show. that was fine work.
but now i need also only show category image. not loop all child category.
example my category like bellow
- Printing (main category)
- – 4 color (child category)
- – 2 color (child category)
- – offset print (child category)
so now when i will view/access 4 color category (cat-printing.php this page for all printing child category template ) then in that page will show 4 color category image only
i tried you code not work really . it show error foreach($categories as $category){
Hi @pagol
I’m not sure if I understand your explanation, so please forgive me if I’m wrong.
To show the image for the child category, I believe you can do it like this:
$current_term = get_queried_object();
$image = get_field('cat_thumbnail_image', $current_term );
echo '<div class="test">'.$image.'</div>';
If that is not what you want, could you please share some screenshots of the issue with notes on how you want it to be?
Thanks 🙂
wow… cool !!!!! @James … it work super 🙂 thank you so much.
two issue solve it here 🙂
Thanks again for great and quick support
Hi James, I saw this topic and I am facing the same issue as some others here. Maybe you can help me out too, here 😉
I have the following code:
<?php
foreach ( $terms as $term ) {
$image = get_field('berufe-thumb', $term->taxonomy . '_' . $term->term_id );
echo '<pre>';
echo "Image field value:";
var_dump($image);
echo '</pre>';
?>
The result is: Image field value:NULL
Could you have a look at it, please?
