Amo model supported

• LeadModel
• ContactModel

How to use

Localization

Before use set necessary localization (at now supported only en and ru).

LocaleService::setLocale('ru');

Basic usage

$this->typeFactory = new CommonTypeFactory(); // creates inner representation of AmoCRM custom fields

$this->handlerFactory = new HandlerFactory($this->logger); // creates handler decides placeholder of given custom field looks like
$this->placeholderFactory = new PlaceholderFactory(); // creates placeholder of given custom field representing entity (like 'Lead') and name (like 'Name of lead')

$this->placeholderBuilder = new CommonPlaceholderBuilder($this->logger, $this->handlerFactory, $this->placeholderFactory); // creates an array of placeholders strings of given entity type

$this->customFieldMapper = new CustomFieldMapper($this->logger); // creates an inner representation of AmoCRM custom fields from Amocrm custom field model
$this->entityMapperFactory = new CommonEntityMapperFactory( $this->typeFactory, $this->logger); // creates an inner representation of AmoCRM entity from Amocrm entity model
$this->replacer = new CommonReplacer($this->logger, $this->handlerFactory, $this->placeholderFactory); // creates an array with placeholders values as key and model values as values

/**
 * parses given string template with placeholders and substitutes given model values
 */
$this->templateProcessor = new MessageTemplateProcessorService( 
    $this->logger,
    $this->placeholderBuilder,
    $this->customFieldMapper,
    $this->entityMapperFactory,
    $this->replacer
);

$contactCustomFields = $amocrmClient->customFields(EntityTypesInterface::CONTACTS)->get();

$placeholders = $this->templateProcessor->getVariables(EntityTypeEnum::CONTACT, $contactCustomFields) // managers may choose placeholders from list during client message creation

// then

$contact = new ContactModel();
$contact->setName('John');

$template = 'Hello, {{Contact / Name of contact}}!';

$message = $this->templateProcessor->replaceVariables($template, $contact); // results in Hello, John!

Explanations

1. If there is no value for given placeholder, it will be replaced with empty string.
2. Placeholders pattern consists of entity type and field name divided by '/' like {{Lead / Custom field name}}, so it may result in string of Lead entity even if there is no custom field named 'Custom field name' if getVariables method is used with type Lead but custom fields of Contact entity.
