Hi, i’ve created a repeater field that it is generated by registering contacts. For example, my repeater field have the following sub fields:
– name
– email
– message

This is registered in a frontend form.

In my back of WordPress appears like this (chek the order):

– name 1, email 1, message 1
– name 2, email 2, message 2
– name 3, email 3, message 3

I want to add a filter that appears like this (automatically with the inverted order and for a specific custom post type called “Message Contact”):

– name 3, email 3, message 3
– name 2, email 2, message 2
– name 1, email 1, message 1

Please, can you help me?? Thanks

i don’t know if it is possible to filter at backend without one of this:

• a additional field that contains the “count”
• a save date_time-field
• any other (own) field that you can order by

where you can order by ASC/DESC

if you have one of this field, than you can use this how-to to order your repeater

if it is only for frontend: than it is no need for such a field. just use something like this
$reversed = array_reverse($your_repeater);

Thanks for answer… ACF’ support commented me about array_reverse, too. Thye give me this code:

function my_acf_load_value( $value, $post_id, $field ) {
// bail early if no value
if( empty($value) ) {
return $value;
}
// return
return array_reverse($value);
}
add_filter(‘acf/load_value/name=my_repeater_field_name’, ‘my_acf_load_value’, 10, 3);

But appears the next error:

Warning: array_reverse() expects parameter 1 to be array, string given in C:\xampp\htdocs\new_useem_wp\wp-content\themes\useem\functions.php on line 203

In line 203:
return array_reverse($value);

What could be happening?

Thanks

I’m running into the exact same issue, I’ve noticed that $value is just a string equal to the number of rows I have saved in the repeater field.

Yes, I’ve put print_r($value) and it returns the number of rows. Ther should be some way that return the array of the rows…. but I dont know how
