How to save repeater field injected into WPJM form

I’m injecting and ACF Pro field group into an existing WP Job Manager job submission form:

/**
 * Inject ACF fields into route submission form.
 * This example uses the WP Job Manager Field Editor hook 
 * field to fire job_manager_field_actionhook_prefix_acf_repeater
 * 
 * @param array $field settings for field
 * @param string $key field key 
 */
add_action( 'job_manager_field_actionhook_prefix_acf_repeater', 'prefix_acf_repeater', 10, 2 );
function prefix_acf_repeater( $field, $key ) {
	// We only want to add this on the front end. 
	// The back end does not need custom display and saving.
	if ( is_admin() ) {
		return;
	}

	 // Insert ACF group field
	 acf_form( [
		 'new_post' => true,
		 'post_id' => 'new_post', // Prevent old form values from being persistent
		 'fields'=> [ 'field_5c9bf22960ed8'],
		'return' => '', // No return value for WPJM compat. // https://support.advancedcustomfields.com/forums/users/jamesryder/replies/
		'form' => false,
		'honeypot' => false,
	] );
}

I am not calling acf_form_head() because it conflicts with the WP Job Manager submission process. I am however, enqueueing acf_enqueue_scripts() so that the JS and CSS are loaded.

add_action( 'init', 'prefix_acf_enqueue_scripts_manually', 1 );
function prefix_acf_enqueue_scripts_manually() {
	acf_enqueue_scripts();
}

I’ve created a callback function for save_post_job_listing (code at the end of this post) which allows me to look at $_POST and save my repeater fields, but this required building a complex custom save function which will break if the field structure is modified.

Does ACF have a built in function that will allow me to manually trigger the saving of this group field? Or alternatively a more straight forward way of getting ACF and WPJM to work together?

It’s my understanding that the acf_update_{thing}() functions only work for fields that have already been saved and that these functions do not work with $_POST, but it also seems like there’s a better way of going about this than what I’m doing.

Here’s the custom save function:

add_action( 'save_post_job_listing', 'prefix_save_group');
function prefix_save_group( $post_id ) {

	$fields = tsr_acf_route_field_ids_days();
	 $fields = [];

	$fields['days'] = [
		'id'   => 'field_5c9bf22960ed8',
		'name' => '_tsr_route_days'
	];

	$fields['stops'] = [
		'id'   => 'field_5c9bf22962649',
		'name' => 'stops'
	];

	$fields['stop_name'] = [
		'id'   => 'field_5c9bf229635e9',
		'name' => 'stop_name'
	];

	$fields['day_notes'] = [
		'id'   => 'field_5c9bf25a6c3e0',
		'name' => 'day_notes'
	];	
	
	// Get array of days data from $_POST
	$days_data = isset( $_POST['acf'][ $fields['days']['id'] ] )
		? $_POST['acf'][ $fields['days']['id'] ]
		: null;

	// Bail if we have no data.	
	if ( null === $days_data ) {
		return;
	}

	// Day repeater (stores number of rows)
	$days_data_count = count( $days_data );
	$meta_key = $fields['days']['name'];
	update_post_meta( $post_id, '_' . $meta_key, $fields['days']['id'] );
	update_post_meta( $post_id, $meta_key,       $days_data_count );
	
	// Loop through days data and save it.
	$day_counter = 0;
	// Days
	foreach ( $days_data as $day ) {
		// Day
		foreach ( $day as $day_field => $day_field_value ) {
			// Day Stops
			if ( $day_field === $fields['stops']['id'] ) {
				// Number of stops
				$stops = $day_field_value;
				$stops_count = count( $stops );

				$meta_key = $fields['days']['name'] . '_' .
										$day_counter . '_' .
										$fields['stops']['name'];

				update_post_meta( $post_id, '_' . $meta_key, $day_field );
				update_post_meta( $post_id, $meta_key,       $stops_count );
				
				$stop_counter = 0;
				// Stop fields
				foreach ( $stops as $stop ) {
					// Stop field
					foreach ( $stop as $stop_field => $stop_value ) {
						// Stop Name
						if ( $stop_field === $fields['stop_name']['id'] ) {

							$meta_key = $fields['days']['name']  . '_' .
													$day_counter . '_' .
													$fields['stops']['name'] . '_' .
													$stop_counter . '_' .
													$fields['stop_name']['name'];

							update_post_meta( $post_id, '_' . $meta_key, $stop_field );
							update_post_meta( $post_id, $meta_key,       $stop_value );
						}

						// Stop Notes
						if ( $stop_field === $fields['stop_notes']['id'] ) {

							$meta_key = $fields['days']['name']  . '_' .
													$day_counter . '_' .
													$fields['stops']['name'] . '_' .
													$stop_counter . '_' .
													$fields['stop_notes']['name'];

							update_post_meta( $post_id, '_' . $meta_key, $stop_field );
							update_post_meta( $post_id, $meta_key,       $stop_value );
						}
					}
					$stop_counter++;
				} // Day stop
			} // Day stops
			
			// Day Notes
			if ( $day_field === $fields['day_notes']['id'] ) {

				$meta_key = $fields['days']['name'] . '_' .
										$day_counter . '_' .
										$fields['day_notes']['name'];
										
				update_post_meta( $post_id, '_' . $meta_key, $day_field );
				update_post_meta( $post_id, $meta_key,       $day_field_value );
			}	// Day notes		
		} // Day

		$day_counter++;
	} // Days
}

Just following up…

(And sorry for the double post of the question. My post disappeared when editing, then re-appeared)

I figured out that triggering do_action( 'acf/save_post', $post_id ); is the key. This means that creating a custom save function is not necessary.

add_filter( 'job_manager_update_job_data', 'my_acf_save_repeater_data', 10, 2 );
function my_acf_save_repeater_data( $post_id, $route_data ) {
	do_action( 'acf/save_post', $post_id );

	return $route_data;
}
