Validation select custom using wpcf7_add_shortcode

  • Hello,
    I need help to validate a select I created through wpcf7_add_shortcode.

    When selected “notselect” I want to present an error message and do not send the form.

    I’ve tried everything! I thank anyone who can help me.

    The code of my select:

    wpcf7_add_shortcode('eventos_lista', 'createbox', true);
function createbox(){
			$lista_produtos = new WP_Query(array('showposts'=>100, 'post_type' => 'eventos'));
			$output = "<select name='evento' id='evento' class='form-control' onchange='document.getElementById(\"evento\").value=this.value;'><option value='notselect'>Evento</option>";
			//foreach ( $myposts as $post ) : setup_postdata($post);
			while ($lista_produtos->have_posts()) : $lista_produtos->the_post();

				$data = rwmb_meta( 'paulo_date' );
				$ativo = rwmb_meta( 'paulo_radio' );
				$title = get_the_title();
				if($ativo == 1) {
					$output .= "<option value='$title'>$title - $data</option>";
				}

			endwhile;
			$output .= "</select>";
			return $output;
}

    thanks!

    Takayuki,
    I created the code below:

    add_filter( 'wpcf7_validate_eventos_lista*', 'custom_email_confirmation_validation_filter', 20, 2 );
function custom_email_confirmation_validation_filter( $result, $tag ) {
    $tag = new WPCF7_Shortcode( $tag );

    if ( 'evento' == $tag->name ) {
        $evento = isset( $_POST['evento'] ) ? trim( $_POST['evento'] ) : '';

        if ( $evento == 'notselect') {
            $result->invalidate( $tag, 'Selecione um evento acima.' ) );
        }
    }
    return $result;
}

    The filter is working, however it does not have the phrase “Please fill the required field.” under the select I created, similar to most inputs.

    If you want to see running: https://breventos.net/confirme-sua-presenca/

    thanks!
