[Lilug-dev-sig] Lilug Dev-Sig Meeting Tonight (8/19) @ 8pm

[Robert Wilkens]

Read a little further down:

// The result of the expression (true && false) is assigned to $g
// Acts like: ($g = (true && false))
$g = true && false;

// The constant true is assigned to $h and then false is ignored
// Acts like: (($h = true) and false)
$h = true and false;

Note one very important difference in the comments of how they work.

Rob,

I'm pretty sure 'and' and '&&' are equivalent in PHP.  I just checked here:

http://php.net/operators.logical

I'm pretty sure it's more of a mediawiki cache problem than a coding problem in the extension.  Of course, I may very well be mistaken.

Mark.

As I understand it, for what you are doing you want to use, like in c, the 2-character ampersand or && to do what you want to do there.  i.e. if ((this)&&(that)){dothis}; as opposed to if ((this)and(that)){dothis};.. I'm not sure how it interprets the word 'and' but I googled around and confirmed with some basic self-reaffirmation that && is perhaps the more accurate symbol there.  Please correct me if I'm wrong, and if that still doesn't fix it, get back to me either way because I didn't go much further than that in my reading over.

> I remember when I first wrote the extension that mediawiki's caching was getting in the way.  I took steps to disable caching in certain circumstances, but that was a few versions of mediawiki ago.  So, who knows if that is still working correctly.  I suspect that mediawiki had a cached version of the page from August 18th, when it would have correctly said "tomorrow, august 19th" and then incorrectly served that same page out of the cache on August 19th.  I saw this problem first-hand today.  When I first went to the page it said "today, august 19th", even though it is the 20th today.  After logging in to the wiki it changed to say "september 16th" which is when the next dev-sig meeting is.  With that said, for some reason I'm now seeing that the day of the week isn't being shown when it should.  It says 'september 16th' instead of 'thursday, september 16th'.  Very weird.
