Well, at this point, I’ve arrived to a code that is working without bugs, but it keeps failing in its purpose:

add_filter( 'wpcf7_validate_checkbox*', 'user_plan_validation_filter', 20, 2 );

function user_plan_validation_filter( $result, $tag ) {
	$tag = new WPCF7_Shortcode( $tag );

	$field = 'user-plan';

	if ( $field == $tag->name ):
		if ( isset( $_POST['user-plan'] ) ):
			$user_plan = trim( $_POST['user-plan'] );
		else:
			$user_plan = '';
		endif;

		if ( $user_plan == '' ):
			$result->invalidate( $tag, "Selecciona un plan para poder finalizar el tramite" );
		endif;
	endif;
 
	return $result;
}

Using the PHP Error Log I checked that all the variables are being filled with the values I expect, the conditional sentences also are working as expected, but the validation message keeps showing the one setted in the Contact Form configuration.

Any help?

Thanks!

Got it! That bug is solved. Here’s the code:

add_filter( 'wpcf7_validate_checkbox*', 'user_plan_validation_filter', 10, 2 );

function user_plan_validation_filter( $result, $tag ) {
    $tag = new WPCF7_Shortcode( $tag );
 
    if ( $tag->name == 'user-plan' ) {
    	$user_plan = $_POST['user-plan'];
        // $user_plan = isset( $_POST['user-plan'] ) ? trim( $_POST['user-plan'] ) : '';
 
        if ( $user_plan == '' ) {
            $result->invalidate( $tag, "Selecciona un plan para poder finalizar el tramite" );
        }
    }
 
    return $result;
}

Now the validation process doesn’t get stuck, but the validation message shown is not my custom one but the one set in the form options. What can I be doing wrong?

Thanks a lot for your help Takayuki, cheers!
