Pre-populate number field from CPT custom field

Hi @joecam

I hope you are doing well.

There are some hook available for that, just before sharing the code, could you let us know:

– Is it a fixed post/page that you have the ID, OR
– Is it dynamic we need to get an ID on the fly?

Best Regards

Hi Patrick,

Thank you for your response.

It is a dynamic page for every CPT detailed page. I would need to get and populate a number field in the form based on the CPT’s custom field, to be able to fill payment field with value.

Hi @joecam

I pinged our SLS Team to review this and we will get back with some update as soon this is possible.

Kind Regards,
Kris

Hi again @joecam

This snippet should help. In the code?2910?should be changed to your form ID and?number-1?should be changed to your number field’s ID (need to change on multiple places).

add_action( 'forminator_before_form_render', 'wpmudev_number_field_value_form', 10, 5 );
function wpmudev_number_field_value_form( $id, $form_type, $post_id, $form_fields, $form_settings ) {
	if ( 2910 == $id ) {
		add_filter( 'forminator_field_number_markup', 'wpmudev_add_value_field_cpt', 10, 5 );
	}
}

function wpmudev_add_value_field_cpt( $html, $id, $required, $placeholder, $value ) {
	$meta_val = '';
	if ( strpos( $id, 'forminator-field-number-1' ) !== false ) {
		$meta_val = get_post_meta( get_the_ID(), 'your_meta_key', true );
		$html = str_replace( 'name="number-1"', 'name="number-1" value="'.$meta_val.'"', $html );
	}
	
	return $html;
}

Thank you so much, it is working as expected.

Note for other users looking for the same solution: need to replace your_meta_key in the code with the key of the custom field from ACF.

Thank you!
