Thank you for reporting Jaume.
It is fixed. It was coming from 3rd party library class we had included. I have added the fix in the 1.0.8 and is available from wp.org now.

Hi Nana,
I am about to do it for a project of mine with Community Builder. I will share the code as a blog post next week.

Thank you

Hi Carl,
Thank you for posting.

You can easily create a load more or infinite scroll behaviour using the MPP_Media_Query
https://buddydev.com/mediapress/topics/api-reference/core/mpp_media_query/

Also, we do plan to add this as a standard feature sometime in future.

PS: Thank you for letting me know about the demo. The issue was cropping up dues to the way WordPress behaves with mysql strict mode. we have it fixed now.

Thank you
Brajesh

Hi Dennis,
Here is the example

function buddydev_validate_field_dennis() {

	$field_1 = 12;//the first field which has two options
	//since field one is required, we don't validate if it is not present, Bp will take care of it
	if ( ! isset( $_POST[ $field_1 ] ) ) {
		return;
	}

	$value = $_POST[ $field_1 ];////make sure to escape it , I don't know expected type, so have left it.

	//if we are here, one of the option has been selected, so

	$bp = buddypress();

	if ( $value == 'a' ) {
		//check if question 2( assume field id 13) is present
		if ( empty( $_POST['field_13'] ) ) {
			$bp->signup->errors['field_13'] = 'This is a required field, you should not askip it';
		}

	} elseif ( $value == 'b' ) {

		//in this case, field_14, field_15, field_16 is required
		$required_fields = array( 14, 15, 16 );
		foreach ( $required_fields as $field_id ) {
			if ( empty( $_POST[ 'field_' . $field_id ] ) ) {
				$bp->signup->errors[ 'field_' . $field_id ] = 'Required field.';
			}

		}

	} else {
		//not of the allowed value
		$bp->signup->errors[ $field_1 ] = 'Please make sure to use a valid value.';
	}
}

add_action('bp_signup_validate', 'buddydev_validate_field_dennis' );

You will need to update the field ids and the value of the first field( ‘a’, ‘b’ with actual values)

I hope you can take it from there.
