Check for conditions to proceed

This trigger allows to have custom conditions to be checked before rest of the triggers can be processed.

One of the few possible scenarios can be

Collecting multiple fields before next trigger can be executed
Comparing user message with internal chat variable. E.g you set chat variable and later you want that visitor entered correct text.

Attribute supported placeholders

Attribute supports these placeholders

lhc.<main chat attribute> E.g lhc.email, lhc.nick, lhc.phone etc. See swagger for all attributes.
<identifier> - this can be either custom attribute Field identifier or just array key from chat_variables
<chat_variable> - identical to {args.chat.chat_variables_array.<variable_key>} It can be set using Update current chat response response type
So if you set variable bot_touched in attribute field you can use either bot_touched or {args.chat.chat_variables_array.bot_touched}
{args.chat.<main chat attr>} or {args.msg.msg} you can use text matching for visitor message.
online_department use as attribute to check is department online (respects department online hours and operators online statuses). In value field 1 means online, 0 - means offline
online_op_department use as attribute to check is department online (ignores department online hours) and checks only for operators. In value field 1 means online, 0 - means offline
online_department_hours use as attribute to check is department online by online hours settings (ignores ignores operators statuses). In value field 1 means online, 0 - means offline
siteaccess you can use this attribute to check what siteaccess visitor is on and execute appropriate trigger. E.g if you want different response by language. eng,lit list of default siteacess
chat_files check does chat has files
- chat_files > 0 - chat has files
- chat_files contains pdf,jpg - chat has pdf or jpg
operator_files same checks as chat_files except only for operator files
user_files same checks as chat_files except only for visitor files
{validation_event__<event_name>} E.g {validation_event__my_event_validator} event with my_event_validator will be dispatched and result afterwards compared with expected output. my_event_validator = 1

If you do not enter Value means it's empty.

E.g

so lhc.email != <empty> as in screenshot. Means I'm checking that e-mail would not be an empty string.
{args.msg.msg} I'm expecting message to contain one of the words dispute, chargeback, refund{2}, money back, contact bank. Refund word can have two typos.

How to validate `{validation_event__<event_name>}`

class erLhcoreClassExtensionValidateevent
{

    public $configData = false;

    public function __construct()
    {
        
    }

    public function run()
    {
        $dispatcher = erLhcoreClassChatEventDispatcher::getInstance();
        $dispatcher->listen('chat.genericbot_event_handler', 'erLhcoreClassExtensionValidateevent::genericEventHandler');
    }
    
    public static function genericEventHandler($params)
    {
        if ($params['render'] == 'my_event_validator') {
            return array(
                'status' => erLhcoreClassChatEventDispatcher::STOP_WORKFLOW,
                'validation_result' => 1
            );
        }
    }
}
