Hi,

I have the date_diff function working and that gives me the difference between two dates in terms of days, months or years. However, I was wondering if it was possible to subtract one date from another and show the answer as a complete date?

I.E. 2011/12/01 - 2010/06/01 = ??/??/??

Is this possible with smarty?

Thanks

Chris

That doesn't make sense. What it the answer to your example?


I.E. 2011/12/01 - 2010/06/01 = ??/??/??


You can get the number of seconds between the dates, but there isn't a "date" that equals to.

Yes, your right. On reflection what I need is to minus a fixed number of days from a date.

So for example,

18/11/2010 - 7 Days = 11/11/2010

Is that possible?

Thanks for your time

date_format will take anything strtotime() will process, so this works:

{"-7 days"|date_format:"%Y-%m-d%"}

If you want a date exactly 7 days ago.

Hi,

Thanks for that, I cant quite get it working though. Is this correct,

{$date|"-7 days"|date_format:"%Y-%m-d%"}

Im guessing not as it doesnt work, or any of the other variations I have tried.

Thanks

its only working on now(), not an arbitrary date, as in my example.

You could subtract 86400*7 from a datestamp, then pass that to date_format. Or write a plugin that does this in PHP:

strftime('%Y-%m-%d',(strtotime($date)-(86400*7)));

assuming $date is a date parsible by strtotime().

what is this for specifically? maybe a plugin exists for what you want.

Hi,

Thanks for your helps. I got it working now. I just wanted to create a payment date 6 weeks before another variable date. See below.


<!-- payment date check starts here -->
{capture assign="unix"}{$entry->fields.date->value}{/capture}
{math equation="x - y" x=$unix|strtotime y=3628800 assign="payment_date"}
<!-- payment date check ends here -->
<tr>
<td><em>Payment Due:</em></td>
<td><em>{$payment_date|date_format:"%d/%m/%Y"} (6 weeks before the course date)</em></td>
</tr>


Thanks

Chris
