There isn’t enough information to give an exact answer, but in general you can pre-populate a repeater this way.
// this filter has the field key of the repeater field
add_filter('acf/load_value/key=field_123456', 'my_repeater_values', 20, 3);
function my_repeater_values($value, $post_id, $field) {
// generate rows of the repeater
// see next code snippet
return $value;
}
The value you generate needs to be a nested array
// $value format
$value = array(
// you add a nested array for each row
array(
// this nested array holds the field key => value pairs for each sub field
'field_234567' => 'value of sub field 1',
'field_345678' => 'value of sub field 2'
),
// second row of repeater
array(
// this nested array holds the field key => value pairs for each sub field
'field_234567' => 'value of sub field 1',
'field_345678' => 'value of sub field 2'
),
// etc....
)
this does not include any checking. For example, you probably do not want to overwrite existing values/rows and want to add new rows when new users are added. I also don’t know exactly what information you want to store.
However, I would probably store the commission information you want to store as a custom field on the user profile page in a field group that is only available to site admins and then get the information from there when I need it.
