Hi @sami616

Could you please tell me if this “registration template” is on front end or back end?

If it is on the front end, I think you can add a hidden input on your form to mark it as a registration page. Maybe something like this:

acf_form(array(
    'html_after_fields' => '<input type="hidden" name="acf[register]" value="true"/>',
));

After that, you can check this hidden input using the $_POST variable. It should be something like this:

add_filter('acf/validate_value/name=sr_email', 'my_acf_validate_email', 10, 4);
function my_acf_validate_email( $valid, $value, $field, $input ){
	
	if( !$valid ) {
		return $valid;
	}
    
	if(($_POST['acf']['register'] == 'true') && email_exists($value)){
		$valid = 'Email already in use';
	}

	return $valid;
}

I hope this helps.
