I have a “Repeater” field which is generated like this:
if(function_exists("register_field_group"))
{
register_field_group(array (
'id' => 'acf_custom_object',
'title' => 'Custom Object',
'fields' => array (
array (
'key' => 'custom_images',
'label' => 'Images',
'name' => 'image_urls',
'type' => 'repeater',
'sub_fields' => array (
array (
'key' => 'custom_image',
'label' => 'Image',
'name' => 'image_url',
'type' => 'text',
'column_width' => '',
'default_value' => '',
'placeholder' => '',
'prepend' => '',
'append' => '',
'formatting' => 'html',
'maxlength' => '',
),
),
'row_min' => '',
'row_limit' => '',
'layout' => 'row',
'button_label' => 'Add Row',
),
),
'location' => array (
array (
array (
'param' => 'post_type',
'operator' => '==',
'value' => 'my_custom_post_type',
'order_no' => 0,
'group_no' => 0,
),
),
),
'options' => array (
'position' => 'normal',
'layout' => 'default',
'hide_on_screen' => array (
),
),
'menu_order' => 0,
));
}
The field is NOT generated by Admin GUI, it gets generated in my functions.php together with the custom post type it belongs to.
No I have the problem, that I could not add repeating values by a hook. It seems like in my hooked function the fields generated by code and not by GUI are not known/fillable?!
Hooked function:
function post_saved($post_id)
{
$images = array('test1.jpg', 'test2.jpg', 'test3.jpg');
$values = array();
foreach ($images as $n => $image) {
$values[]['image_url'] = $image;
}
update_field('field_53562b25c883a', $values, $post_id);
}
add_action('pmxi_saved_post', 'post_saved', 10, 1);
UPDATE:
Ok, I’ve found the reason why the field (generated in functions.php) is not recognized in other hooks. It seems like the fields have to start with “field_”!!!
