Magento 2: Plugin before/around/after Interaction

Plugins are sorted by sort order first, and then by method prefix.

Example: for method with 3 plugins (PluginA, PluginB, PluginC) with following methods and sortOrder:

• PluginA (sortOrder = 10)
  • beforeDispatch()
  • afterDispatch()
• PluginB (sortOrder = 20)
  • beforeDispatch()
  • aroundDispatch()
  • afterDispatch()
• PluginC (sortOrder = 30):
  • beforeDispatch()
  • aroundDispatch()
  • afterDispatch()

Execution flow should be following:

• PluginA::beforeDispatch()
• PluginB::beforeDispatch()
• PluginB::aroundDispatch()
  • PluginC::beforeDispatch()
  • PluginC::aroundDispatch()
    • Action::dispatch()
  • PluginC::afterDispatch()
• PluginB::afterDispatch()
• PluginA::afterDispatch()

From the Magento 2 cookbook:

If there are multiple plugins that extend the same original function, they are executed in the following sequence:

• the before plugin with the lowest sortOrder
• the around plugin with the lowest sortOrder
• other before plugins (from the lowest to highest sortOrder)
• other around plugins (from the lowest to highest sortOrder)
• the after plugin with the highest sortOrder
• other after plugins (from the highest to the lowest sortOrder)
