Hi. I have an image custom field in each category. On my parent category page I am then displaying the children of that category along with title, link, description and the custom field image. The problem I have is that an image does display for each child but it’s the same one rather than each child category’s image. Here’s the code I’m using in my parent (the image custom field is “cat_half_image”):
`
<?php
$cat = get_query_var(‘cat’);
$args = array(
‘child_of’ => $cat,
‘orderby’ => ‘name’,
‘order’ => ‘ASC’
);
$attachment_id = get_field(‘cat_half_image’, ‘category_’. the_category_ID( $echo ) .”);
$size = “thumbnail”;
$categories = get_categories($args);
foreach($categories as $category) {
echo ‘<div class=”cat-block g_6″>’;
echo ‘<p>term_id ) . ‘” title=”‘ . sprintf( __( “View all posts in %s” ), $category->name ) . ‘” ‘ . ‘>’ . wp_get_attachment_image( $attachment_id, $size ).’ </p> ‘;
echo ‘<h2>’. $category->name . ‘</h2>’;
echo ‘<p>’. $category->description . ‘</p>’;
echo ‘</div>’; }
?>
Any help or ideas would be greatly appreciate as I’ve been failing with this all weekend!
Hi @greencode
The code you use to populate $attachment_id is OUTSIDE the sub categories loop. Therefor, it will not be dynamic for each category.
You need to move this within the loop.
You may find that the_category_ID doesn’t work within the loop. You will need to use $category->term_id of something similar
Thanks

Hi Elliot,
Really appreciate you taking the time to help out with this. What I’m slightly confused about is that the code I have above is working correctly with the exception of the custom image field i.e. the title, link and description are all pulling in from the sub category correctly so I’m not sure what else to do?
Forgive me here, my coding knowledge is not amazing.

Hi @greencode
The category name is showing because you have written the code WITHIN the loop:
$category->name
Your ACF code doesn’t work because you have written the code OUTSIDE the loop.
My previous comment already outlines this, so if your not able to understand how this effects your code, I highly recommend that you hire a WP developer to help out with your project.
Thanks

Thanks so much for drumming this into me. I’ve finally figured it out. You were correct on both accounts i.e. needed to be inside the loop and also needed to use
$category->term_id
So the final code I have is
<?php
$cat = get_query_var('cat');
$args = array(
'child_of' => $cat,
'orderby' => 'name',
'order' => 'ASC'
);
$categories = get_categories($args);
foreach($categories as $category) {
$attachment_id = get_field('cat_half_image', 'category_'. $category->term_id .'');
$size = "half-img";
echo '<div class="cat-block g_6">';
echo '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . wp_get_attachment_image( $attachment_id, $size );
echo '<h2>'. $category->name . '</h2>';
echo '</a>';
echo '<p>'. $category->description . '</p>';
echo '</div>'; }
?>
Hello,
I’m trying to do the same thing, but ONLY for the current parent category.
Here the code displays all the elements for ALL categories.
Do you know what do I have to adapt ?
Thanks in advance for your help.
