Hi there,
I have what I thought was a very simple thing to do but I am just hitting a brick wall over and over again. I’m hoping someone can help.
The set up: I have a CPT (sponsor) where I have assigned an ACF group (not an acf field group – just a group). Individual posts within the CPT receives input such as an image, child age, sponsorship availability, date of birth, etc. There is also an ID number assigned to each child to help with keeping track.
The problem: On the CPT archive page, I need to sort and display these children by ID number. Going off the principle that you treat a group as you would a repeater field, I have tried several times to use the instructions found at https://www.advancedcustomfields.com/resources/how-to-sorting-a-repeater-field/ to no avail. For some reason, the same child is being repeated over and over, sometimes with strange letters or numbers after the name.
Unfortunately, I do not have an option to remove things from the group to allow for sorting because 180 kids have already been entered and their information all goes away when the sub_fields are moved out of a group.
The code: My CPT is sponsor. My group name is “child_info” ( field key “field_5f99f4b780bbe” ). The group sub_field I want to sort by is “child_idnum” ( field key “field_5f99ed668d9eb” ).
I have placed this code into my functions file:
function my_acf_load_value( $value, $post_id, $field ) {
// vars
$order = array();
// bail early if no value
if( empty($value) ) {
return $value;
}
// populate order
foreach( $value as $i => $row ) {
$order[ $i ] = $row['field_5f99ed668d9eb']; //the name and key match each other
}
// multisort
array_multisort( $order, SORT_ASC, $value );
// return
return $value;
}
add_filter('acf/load_value/name=child_idnum', 'my_acf_load_value', 10, 3); //the name and key match each other
and this (quite pared down for testing) code into my archive-sponsor.php file (pls note: I’ve also tried using the field key(s) here with no luck):
<?php
// Get repeater value
$repeater = get_field('child_info');
// Obtain list of columns
foreach ($repeater as $key => $row) {
$speaker[$key] = $row['child_idnum'];
$fspeaker[$key] = $row['search'];
}
// Sort the data, ascending
array_multisort($speaker, SORT_ASC, $repeater);
// Display newly orded columns
echo '<ul class="br-sl">';
foreach( $repeater as $row ) {
echo '<li>';
echo the_title();
echo $row['child_idnum'];
echo '</li>';
}
echo '</ul><!-- .br-sl -->'; wp_reset_query(); ?>
Any help or direction is greatly appreciated. I’m sure I am missing something simple but I am too close to see what that is.
Thank you!
