I recently ran into a problem where I needed to display the same date several
times on one page, but in different locales. The solution that I came up with
was to extend the {(ftime...)} function to take an optional third parameter
'lc' which takes a locale in which to render the date. Since I use ftime in a
number of places on my site, I was very careful to preserve all existing
functionality, so the following should be a safe drop-in replacement. If you
have a use for it, you can just copy what follows into config.php. I would
like to see this extension added to the core, if other folks find it useful too.
$MarkupExpr['ftime'] = 'lc_ftime($args, $argp)';
## lc_ftime handles {(ftime fmt=x when=y lc=z)} expressions.
##
function lc_ftime($args = NULL, $argp = NULL)
{ global $TimeFmt, $Now, $FTimeFmt;
## get the format string
if( isset($argp['fmt']) )
$fmt = $argp['fmt'];
else if (strpos(@$args[0], '%') !== false)
$fmt = array_shift($args);
else if (strpos(@$args[1], '%') !== false)
list($fmt) = array_splice($args,1,1);
else
{
SDV($FTimeFmt, $TimeFmt);
$fmt = $FTimeFmt;
}
## determine the timestamp
if( isset($argp['when']) )
list($time, $x) = DRange($argp['when']);
else if (@$args[0] > '')
list($time, $x) = DRange(array_shift($args));
else $time = $Now;
## get the locale
if( isset($argp['lc']) )
$locale=$argp['lc'];
else
$locale=array_shift($args);
## make sure we have %F for ISO dates, %s for unix timestamps.
$fmt = str_replace(array('%F', '%s'), array('%Y-%m-%d', $time), $fmt);
## handle locale switch, if need be.
if( isset($locale) )
{
$oldlc = setlocale(LC_ALL,'0');
setlocale(LC_ALL,$locale);
$ret = strftime($fmt,$time);
setlocale(LC_ALL,$oldlc);
}
else
$ret = strftime($fmt,$time);
return $ret;
}
