Features

The module allows you to set the order in which observer instances are executed while dispatching events

Usage

1. Install module via composer:

    composer require driiiftking/module-observers-priority
    bin/magento module:enable Driiiftking_ObserversPriority
    bin/magento setup:upgrade
   

2. In any events.xml file you can use optional priority attribute to set order of executing. Higher priority means earlier execution of the observer. Default priority is 0.

Native events.xml file:

    <event name="some_magento_event">
        <observer name="observer_third" instance="Vendor\Module\Observer\Third"/>
        <observer name="observer_first" instance="Vendor\Module\Observer\First"/>
        <observer name="observer_last" instance="Vendor\Module\Observer\Last"/>
        <observer name="observer_second" instance="Vendor\Module\Observer\Second"/>
    </event>

Likely order of execution: Third > First > Last > Second

Modified events.xml file:

    <event name="some_magento_event">
        <observer name="observer_third" instance="Vendor\Module\Observer\Third" priority="10"/>
        <observer name="observer_first" instance="Vendor\Module\Observer\First" priority="30"/>
        <observer name="observer_last" instance="Vendor\Module\Observer\Last"/>
        <observer name="observer_second" instance="Vendor\Module\Observer\Second" priority="20"/>
    </event>

Order of execution: First > Second > Third > Last

CLI debug tool:

bin/magento dev:observer:info event_name [--area=areacode]

Example

bin/magento dev:observer:info cms_page_render --area=frontend
