[pmwiki-devel] When Readpage fails

[Daniel Roesler]

Correct me if I'm wrong, but you might want to check
RetrieveAuthPage() for a response of 'null'.
<http://www.pmwiki.org/wiki/PmWiki/FunctionList>

What I use:
$page = RetrieveAuthPage($pagename, "edit");
if(!($page === null))

where you use === instead of ==, since a return of 0 or false might
still be accepted as false.

Avast!
