    In the Content module I'm pulling in a dynamic image that uses a date range built in the URL like

    Code

    &bdate=20100429&edate=20100501


    The range I need for the dynamic content is today's date plus two days.

    So I've got a custom template in the /themes/mytheme/templates/modules/content/ folder with this code (URL trimmed down for clarity)

    Code

    <div>
    <!--[assign var='bdate' value=$smarty.now|date_format:"%Y%m%d"]-->
    <!--[assign var='edate' value=$bdate+2]-->
    <img src="/&bdate=<!--[$bdate]-->&edate=<!--[$edate]-->" width="750" height="250" />
    </div>


    This works fine except at the end of the month like today. It produces a non-existent date on the last two days of every month, since for instance today
    20100429
    + 2 = 20100431 (No such date as April 31)

    Is there a way I could change the Smarty variables to correct for this?

    Note about the forum

    I'm getting a pop-up error box full of errors every time I post or edit a post. The post goes through, but freezes up the browser so it looks like nothing has happened.

    here's what I get, it's late so maybe someone is working on the forum.

    Code

    I dont' know how to do this in smyrty, but you can write your own little Smarty modifier.
    Maybe this is what you are searching for: http://bytes.com/topic/php/answers/857706-addition-subtraction-smarty

    agreed that a Smarty modifier would be easiest.

    have the modifier accept the date string
    create a datetime object from the formatted string
    modify the datetime object to add two days
    return new formatted string.
