WordPress Cross Reference

Functions that are not part of a class:

Retrieve the author of the current post.

param: string $deprecated Deprecated.
return: string The author's display name.

the_author( $deprecated = '', $deprecated_echo = true ) X-Ref

Display the name of the author of the current post.

The behavior of this function is based off of old functionality predating
get_the_author(). This function is not deprecated, but is designed to echo
the value from get_the_author() and as an result of any old theme that might
still use the old behavior will also pass the value from get_the_author().

The normal, expected behavior of this function is to echo the author and not
return it. However, backwards compatibility has to be maintained.

param: string $deprecated Deprecated.
param: string $deprecated_echo Deprecated. Use get_the_author(). Echo the string or return it.
return: string The author's display name, from get_the_author().

get_the_modified_author() X-Ref

return: string The author's display name.

the_modified_author() X-Ref
