Hi Tosin,
Thank you for the reply.

Although it is fine to do that, I will rather write a function. If you check, there are 3 things which vary field id, value and error message.

You can remove the previous code and use the following instead.

// forces user to select a specific select field value on registration page.
add_action( 'bp_signup_validate', function () {
	bd_tosin_validate_signup_field( 4448, 'I accept', 'This is a required field. You must accept.' );

	// You can uncomment the below function and specify your value. Repeat it as you need.
	// bd_tosin_validate_signup_field( 2, 'some other value', 'Your error message' );
	// bd_tosin_validate_signup_field( 2, 'some other value', 'Your error message' );

} );

/**
 * Validates BuddyPress signup field.
 *
 * Makes sure that the user entered value is same as the expected value. If not, the specified error will be shown.
 *
 * @param int $field_id
 * @param string $expected_value expected value to match.
 * @param string $error_message Error message to be shown if the values do not match.
 *
 * @return void
 */
function bd_tosin_validate_signup_field( $field_id, $expected_value, $error_message = 'Please try again, the value did not match our expectation' ) {

	if ( ! isset( $_POST[ 'field_' . $field_id ] ) ) {
		return; //should never happen if the field is marked as required.
	}

	$input_value = wp_unslash( $_POST[ 'field_' . $field_id ] );

	if ( strtolower( $expected_value ) !== strtolower( $input_value ) ) {
		buddypress()->signup->errors[ 'field_' . $field_id ] = $error_message;
	}
}

And you can use it for as many fields as you need.

Hi tosin,
Please use the following code

// forces user to select a specific select field value on registration page.
add_action( 'bp_signup_validate', function () {
	$field_id       = 4448; // Your select field id.
	$accepted_value = 'I accept'; // please change with the value you want to accept.

    if ( ! isset( $_POST[ 'field_' . $field_id ] ) ) {
		return; //should never happen if the field is marked as required.
	}

	$selected_val = $_POST[ 'field_' . $field_id ];

	if ( strtolower( $accepted_value ) !== strtolower( $selected_val ) ) {
		buddypress()->signup->errors[ 'field_' . $field_id ] = __( 'This is a required field. You must accept.', 'buddypress' );
	}

} );

please make sure to update the variable $accepted_value with the actual value which you have used for your selectbox.

Hi Greg,
Thank you.

I see the reason why that did not work. The site archive page templates do not use our bundled template. It comes from your theme and it seems to me they have it hardcoded. I will be looking into the theme this weekend and get back to you with a proper suggestion.
