Hidden field getting data from ACF

Hi @fdcommunication

I hope you are doing well today.

I pinged our SLS Team to review your query and double-check if this snippet is still valid. We will post an update here as soon as more information is available.

Kind Regards,

Hi again @fdcommunication

We have track main issue which is your “acf_reference_du_circuit”.

The custom field name should be reference_du_circuit . If you’re keeping the custom field name acf_reference_du_circuit then it won’t work.

The snippet is such that it will exclude?acf_and then will use the rest of the string in?get_field?function.

In short the hidden field it should be?acf_reference_du_circuit?and custom field name should be?reference_du_circuit

Kind Regards,
Kris

Hello,

Thank you for your answer !

My ACF field is reference_du_circuit. So I put this code in Snippets plugin:

add_filter( 'forminator_field_hidden_field_value', function( $value, $saved_value, $field ){
	if( ! empty( $field['default_value'] ) && 'custom_value' === $field['default_value'] && strpos( $value, 'reference_du_circuit' ) !== false ){
		$field_keys = explode('reference_du_circuit', $value );
		$post_id = false;//default is current post/page
		$value = get_field( $field_keys[1], $post_id );
	}
	return $value;
}, 10, 3 );

Then I add a hidden field {hidden-2} to my form. Select custom value and write reference_du_circuit in custom value field.

Unfortunately it doesn’t work :(.

In my submission form it is only written “Hidden” without the content of my acf field.

What can I do ?

Hi @fdcommunication

You should use the original code:

add_filter( 'forminator_field_hidden_field_value', function( $value, $saved_value, $field ){
	if( ! empty( $field['default_value'] ) && 'custom_value' === $field['default_value'] && strpos( $value, 'acf_' ) !== false ){
		$field_keys = explode('acf_', $value );
		$post_id = false;//default is current post/page
		$value = get_field( $field_keys[1], $post_id );
	}
	return $value;
}, 10, 3 );

Only change is that in the hidden field’s custom value you should write?acf_reference_du_circuit?instead of?reference_du_circuit

It works ! Thank you very much.

And thank you for being so reactive !

Have a good day.
