Hi guys,
I trying to create a new custom field type, where the user can click on an image and there by create a point on that image (X and Y). The point is represented in the two input fields underneath the image.

So far, I have downloaded the ACF Field Type starter-kit and added the image and the input fields to the frontend, but I need to understand how to save data and pass data around in from javascript to php (class-XXX-field-XXX-v5.php)

In the render_field_settings function I’ve added point_x and point_y to hold the two values, but I dont know if that is right?

acf_render_field_setting( $field, array(
			'label'			=> __('Point X','acf-overlay-point'),
			'instructions'	=> __('Customise the X point','acf-overlay-point'),
			'type'			=> 'number',
			'name'			=> 'point_X',
		));

and

acf_render_field_setting( $field, array(
			'label'			=> __('Point Y','acf-overlay-point'),
			'instructions'	=> __('Customise the Y point','acf-overlay-point'),
			'type'			=> 'number',
			'name'			=> 'point_Y',
		));

Or maybe a good tutorial?
