Debugging magento

Debugging in Magento

You probably already have PHP Storm and xdebug running to debug Magento. If not see computer_apps_accounts_installation_setup.

There are more tools and settings that help you to debug Magento.

One of those tools what may come handy is alternate template hints module called Aoe_TemplateHints by Fabrizio Branca. iec-mod-import Aoe_TemplateHints

Firefox add-on

These add-ons work in Linux, Mac, Windows.

“easy xdebug” let you start a xdebug-session.

“Firebug” let you see everything that happens on the client side in the web browser.

Admin settings

In Admin – > System -> Configuration -> Developer you find settings for Profiler and Logging.

Change “Current configuration scope” on the upper left to get more debug settings for each scope.

Settings “Template Path Hints” and “Add Block Names to Hints” show you the name of each block the page is built from.

Developer mode

Magento can be set into Developer mode. This means that you can se more error messages that is normally hidden.

If you look at Index.php you find the following:




This code checks the MAGE_IS_DEVELOPER_MODE environment variable in Apache.

You can activate this variable in your local MAMP-installation, and you can get all messages.

See this page: magento_developer_mode

Observe: Developer mode affect the translations.

Normal is 1. Inline, 2. Site tranlate.csv, 3. module translation, 4. the string in the template

With developer mode you get 3 and 4.



You can send a string to a log file and then look in that file.
