Frequently in the templates, I see code like this:
I understand what it’s doing, but what exactly is _e? I didn’t see that in the Template Tags, Conditional Tags or one other page about tags that I viewed in the Codex, and searching for “_e” doesn’t result in anything. Where is this set? Thanks!
Searches the localization module for the translation of $message, and passes the translation to the PHP echo statement. If no translation is found for $message, it just echoes $message.
__() is used when the message is passed as an argument to another function; _e() is used to write the message directly to the page.
