Creating conditions

Mailcoach ships with a ConditionAction that allows you to define a condition and split the automation in a true and false branch.

By default this action ships with 3 conditions:

• Subscriber has a specific tag
• Subscriber has opened an automation mail
• Subscriber has clicked (one or all) links in an automation mail

You can also create your own conditions by creating a class that implements the Spatie\Mailcoach\Domain\Automation\Support\Conditions\Condition interface.

Let's take a look at the HasTagCondition class as an example:

<?php

namespace Spatie\Mailcoach\Domain\Automation\Support\Conditions;

use Spatie\Mailcoach\Domain\Audience\Models\Subscriber;
use Spatie\Mailcoach\Domain\Automation\Models\Automation;

class HasTagCondition implements Condition
{
    public function __construct(
        private Automation $automation,
        private Subscriber $subscriber,
        private array $data,
    ) {
    }

    public static function getName(): string
    {
        return (string) __('Has tag');
    }

    public static function getDescription(array $data): string
    {
        return (string) __(':tag', ['tag' => $data['tag']]);
    }

    public static function rules(): array
    {
        return [
            'tag' => 'required',
        ];
    }

    public function check(): bool
    {
        return $this->subscriber->hasTag($this->data['tag']);
    }
}

##__construct

The construct method receives the current automation, the subscriber you're checking on and an array of data.

The array of data is only used by the default conditions, custom conditions will always receive an empty array.

##getName & getDescription

The static getName() method gets called to show the name of the condition in the dropdown. The getDescription() method gets shown on the summary of the action.

##check

The check() method is the heart of your condition. Anything is possible in this method, in the example above we're simply checking if the subscriber has a specific tag.
