Set a minimum and a maximum for tags

[Heizpad]

Hi there!

Other than categories (where a user can only choose one category) for tags the user can choose infinite or none at all.

Is there a way to set a minimum (eg 1) and a maximum (eg 3)? Now the user has to choose at least one and is able to choose up to three tags.

Is this possible?

Thank you

Please try this PHP snippet

add_filter( 
	'hivepress/v1/models/listing/attributes', 
	function ($attributes){
		if(isset($attributes['tags'])){
			$attributes['tags']['edit_field']['max_values'] = 3;
		}
		
		return $attributes;
	},
	1000
);

add_filter( 
	'hivepress/v1/forms/listing_update/errors', 
	function ($errors, $form){
		if(count((array)$form->get_value('tags')) < 1){
			$errors[] = 'Please set at least one tag';
		}
		
		return $errors;
	},
	1000,
	2
);
