I searched out for something that does this date formatting stuff (like at youtube comments) and convert a timestamp or datetime into spoken language. I could not find anything that satisfied me, so I sat down and cranked it out.

just three short remarks:
1) the code currently creates german words, but this could be changed easily using the array at top of the function. maybe somebody wants to make it configurable using an parameter.
2) the code works well with unix timestamps generated using time() and also seamless with mysql datetime strings like '2009-06-28 02:22:46'
3) the debug and echo stuff could be ignored or deleted Wink


here is the modifier function, just copy it in a file called modifier.timeAgo.php and place the file in the smarty plugin directory.


hope you enjoy it!


Code:

<?php
/**
 * Smarty plugin
 * @package Smarty
 * @subpackage plugins
 */


/**
 * Smarty date modifier plugin
 * Purpose:  converts unix timestamps or datetime strings to words
 * Type:     modifier<br>
 * Name:     timeAgo<br>
 * @author   Stephan Otto
 * @param string
 * @return string
 */
function smarty_modifier_timeAgo( $date)
{
    // for using it with preceding 'vor'            index
      $timeStrings = array(   'kurzem',            // 0       <- now or future posts :-)
                        'Sekunde', 'Sekunden',    // 1,1
                        'Minute','Minuten',      // 3,3
                        'Stunde', 'Stunden',   // 5,5
                        'Tag', 'Tagen',         // 7,7
                        'Woche', 'Wochen',      // 9,9
                        'Monat', 'Monaten',      // 11,12
                        'Jahr','Jahren');      // 13,14
      $debug = false;
      $sec = time() - (( strtotime($date)) ? strtotime($date) : $date);
      
      if ( $sec <= 0) return $timeStrings[0];
      
      if ( $sec < 2) return $sec." ".$timeStrings[1];
      if ( $sec < 60) return $sec." ".$timeStrings[2];
      
      $min = $sec / 60;
      if ( floor($min+0.5) < 2) return floor($min+0.5)." ".$timeStrings[3];
      if ( $min < 60) return floor($min+0.5)." ".$timeStrings[4];
      
      $hrs = $min / 60;
      echo ($debug == true) ? "hours: ".floor($hrs+0.5)."<br />" : '';
      if ( floor($hrs+0.5) < 2) return floor($hrs+0.5)." ".$timeStrings[5];
      if ( $hrs < 24) return floor($hrs+0.5)." ".$timeStrings[6];
      
      $days = $hrs / 24;
      echo ($debug == true) ? "days: ".floor($days+0.5)."<br />" : '';
      if ( floor($days+0.5) < 2) return floor($days+0.5)." ".$timeStrings[7];
      if ( $days < 7) return floor($days+0.5)." ".$timeStrings[8];
      
      $weeks = $days / 7;
      echo ($debug == true) ? "weeks: ".floor($weeks+0.5)."<br />" : '';
      if ( floor($weeks+0.5) < 2) return floor($weeks+0.5)." ".$timeStrings[9];
      if ( $weeks < 4) return floor($weeks+0.5)." ".$timeStrings[10];
      
      $months = $weeks / 4;
      if ( floor($months+0.5) < 2) return floor($months+0.5)." ".$timeStrings[11];
      if ( $months < 12) return floor($months+0.5)." ".$timeStrings[12];
      
      $years = $weeks / 51;
      if ( floor($years+0.5) < 2) return floor($years+0.5)." ".$timeStrings[13];
      return floor($years+0.5)." ".$timeStrings[14];
}

?>



to use it, in your template:

Code:
(vor {$myDate|timeAgo})


the date must be assigned to $myDate and the output will be e.g.
- (vor 7 Stunden)
- (vor 2 Tagen)

Alright, I am totally new to Smarty but I can understand new stuff.
I added this modifier.timeAgo.php to the plugins folder like instructed, I altered my TABLE to add the time stamp like so:
Code:
ALTER TABLE mytable ADD dt_added TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP


I added some stuff, the new TIMESTAMP displayed perfectly.
eg; each row in dt_added
2009-09-26 19:50:19
2009-09-26 19:50:32
2009-09-26 19:50:35

Now when I call it from my template with: {$dt_added|timeAgo}
It displays the hour from the 1st hour.
Like, 1 new entry now displays '20 Hours Ago' then 1 new entry an hour later displays '21 Hours Ago' so it's not converting the time, just from the date.

Am I doing something wrong here? I have been fidgeting with it for hours! Thanks!

Hi atl,

are you sure, that your variable $dt_added contains the correct timestamps?
I tried your format and it worked correctly.

Code:
{assign var='myDate' value='2009-09-26 19:50:19'}
vor {$myDate|timeAgo}


output: vor 2 Monaten


The timeAgo modifier displays the distance since the start of the unix timestamps (e.g. 1970) if no correct timestamp is given:

Code:
{assign var='myDate' value='something wrong'}
{$myDate|timeAgo}


output: vor 41 Jahren


hope this helps you out

ah and the timestrings array should be localized into your language of course. The code at the top is displaying german.

best regards
Stephan

I figured out why this is not working for me. The timestamps I am using only display date eg; 2009-09-26 00:00:00 and not date and hr:min:sec eg; 2009-09-26 19:50:19
Script works fine, thanks everyone.
