So this is a minor aesthetic change, but would be neat if not difficult to implement. I often want to set a starting number of rows for a repeater field (e.g. when going to edit, show 4 rows by default). The only way to do this at the moment is to set a minimum number of rows, which isn’t ideal as occasionally there might need to be fewer rows than the default.
This can be done with the acf/load_value filter https://www.advancedcustomfields.com/resources/acfload_value/.
add_filter('acf/load_value/name='your-repeater-field-name', 'your_set_repeater_default_values_function_name', 10, 3);
function your_set_repeater_default_values_function_name($value, $post_id, $field) {
if ($value !== NULL) {
// value will be exactly NULL if the field has never been updated
// ie on a new post. If it is not null then you don't want to
// overwrite what's there
return $value;
}
// set new value
$value = array(
// a nested array for each row
array(
// and array item for each field
// use field keys
'field_1234567890abc' => 'default value',
'field_01234567890ab' => 'default value',
// etc...
),
// another row
array(
// etc...
),
);
}
Fantastic – did not know about that – thank you
