Date

Come regola generale, passate sempre le date a Smarty in forma di timestamp. Questo consente ai progettisti di usare date_format per un pieno controllo sulla formattazione delle date, e rende semplice anche il confronto fra date quando necessario.

Note

A partire da Smarty 1.4.0, potete passare date a Smarty come timestamp unix, timestamp mysql, o qualsiasi altro formato leggibile da strtotime().

Example 18.4. uso di date_format


{$startDate|date_format}

    

Questo stamperà:


Jan 4, 2001

    

{$startDate|date_format:"%Y/%m/%d"}

    

Questo stamperà:


2001/01/04

    

{if $date1 < $date2}
   ...
{/if}

    

Quando usate {html_select_date} in un template, il programmatore probabilmente vorrà convertire l'output del modulo in un formato timestamp. Ecco una funzione che può aiutarvi in questo.

Example 18.5. convertire le date provenienti da un modulo in timestamp


<?php

// stabiliamo che gli elementi del modulo si chiamino
// startDate_Day, startDate_Month, startDate_Year

$startDate = makeTimeStamp($startDate_Year, $startDate_Month, $startDate_Day);

function makeTimeStamp($year="", $month="", $day="")
{
   if(empty($year)) {
       $year = strftime("%Y");
   }
   if(empty($month)) {
       $month = strftime("%m");
   }
   if(empty($day)) {
       $day = strftime("%d");
   }

   return mktime(0, 0, 0, $month, $day, $year);
}
?>
