Show current date without a snippet

  • netProphET Reply #1, 9 years, 5 months ago
    Just a quick tip while it's in my head (from updating my band's sadly neglected site).

    I wanted to put the current year in the footer of my site, without bothering with a snippet. (If there are any magic settings containing the current time, I could not recall. Maybe there are.) But here's a simple way to do it in any case:

    [[!+nowdate:default=`now`:strtotime:date=`%Y`]]


    The "nowdate" placeholder doesn't really exist, but giving it a default value of "now" gets you a value to pass along. Pass that to the strtotime filter, you get the current unix timestamp. Pass that to the date filter, you get any representation of the current date you want.

      If you want this to change with the actual date, you need to call it uncached.

          Brilliant. smiley

          I imagine instead of `now` you could probably use `tomorrow` `yesterday` `next week` `next thursday` etc.

            The "now" is simply passed on to the PHP strtotime function internally. So any legal parameter to strtotime could be used. 
            [[+nowdate:default=`2 years ago`:strtotime:date=`%Y`]]



            Examples from here http://php.net/manual/en/function.strtotime.php

            <?php
echo strtotime("now"), "\n";
echo strtotime("10 September 2000"), "\n";
echo strtotime("+1 day"), "\n";
echo strtotime("+1 week"), "\n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "\n";
echo strtotime("next Thursday"), "\n";
echo strtotime("last Monday"), "\n";
?>

              Great found!
              Thanks for sharing
              Would be another good example for chaining multiple output-filters at rtfm:

                Just be aware that it will be a lot more processing-intensive, and thus slower, than a simple snippet, like the CopyYears snippet, which will display the current year or a range of years, like '2000-2014'
                $now = date("Y");
$startYear = $modx->getOption('startYear', $scriptProperties, $now);
$spacer = $modx->getOption('spacer', $scriptProperties, '-');
$years = ($now > $startYear) ? $startYear.$spacer.$now : $now;
return $years;

$spacer = $modx->getOption('spacer', $scriptProperties, '-');
$years = ($now > $startYear) ? $startYear.$spacer.$now : $now;
return $years;

                  have a snippet 'loop'

                  $loops = $modx->getOption('loops',$scriptProperties,10);
$tpl = $modx->getOption('tpl',$scriptProperties,'');

for ($i=0; $i < $loops; $i++){
    $p['idx'] = $i;
    $output[] = $modx->getChunk($tpl,$p);
}

$output = implode('<br />',$output);

return $output;


                  another snippet 'nowdate':
                  return strftime('%Y-%m-%d %H:%M:%S');


                  I call it:

                  [[!loop? &loops=`10000` &tpl=`nowdate`]]


                  having in the nowdate-chunk:
                  [[!+nowdate:default=`now`:strtotime:date=`%Y-%m-%d %H:%M:%S`]]


                  first output: 2014-10-31 07:09:09
                  last output: 2014-10-31 07:09:20

                  having in the nowdate-chunk:
                  [[!nowdate]]


                  first output: 2014-10-31 07:21:34
                  last output: 2014-10-31 07:21:50


                  So, I don't know why,
                  but with the output-filter-version, I have allways about 10secs between the first and last output.
                  With the snippet-version, I have allways about 15secs for 10000 loops.


                  When I replace getChunk in the snippet with strftime directly:

                  $loops = $modx->getOption('loops',$scriptProperties,10);
$tpl = $modx->getOption('tpl',$scriptProperties,'');

for ($i=0; $i < $loops; $i++){
    $p['idx'] = $i;
    $output[] = strftime('%Y-%m-%d %H:%M:%S');
}

$output = implode('<br />',$output);

return $output;


                  there is no difference between the first and last output, so much less than one second without the getChunk - parsing - process.

                    Ok. Sounds good. Not enough difference either way to make a difference.
