How to avoid getting spam from front end form

We don’t have any “official” way to handle that, that I’m aware of, but I wager there are hooks that you could use to output something like hidden fields and whatnot to the form that you can check for upon submission.

Thank you for your answer. I will look for any solution for CMB2 and I will share with you if I find anything.

I’d look into using the honeypot method. Basically, a hidden field that looks like a real field to a bot.. If the field is filled, you know a bot submitted the form.

Hi Justin and Michael,

I added codes below and so far I don’t get any spam from the front end form. I wanted to leave it here just in case for someone who wants to solve this robot spam issue with the front end form.

Thank you for all your help.

Code below is added to function wds_frontend_form_register().

//email 2
	$cmb->add_field( array(
		'name' => __( '', 'wds-post-submit' ),
		'default' => $submitted_author_email,
		'id'   => 'submitted_author_email2',
		'type' => 'text_email',
	) );

Code below is added to function wds_handle_frontend_new_post_form_submission()

// Check email2 submitted
	if ( !empty( $_POST['submitted_author_email2'] ) ) {
		return $cmb->prop( 'submission_error', new WP_Error( 'post_data_missing', __( 'Please enter your email address.' ) ) );
	}
