Pre-install actions - validation
Extensions are installed in control panel from Extension Manager section. Before installation there following checks are performed:

  • check available space
  • is extensions directory writable
  • was extension already installed ( extension upgrade )
  • does extension support used core version
  • does hosting support all php modules used by extension
  • does extension override some controllers/ template files that already overridden by another extension. if two or more extensions override completely same files there will be a conflict, so high priority extension will be used. But, there will be warning in the install about conflict.


Post-install actions

  • check all files list and sizes
  • run install process
