[SOLVED] Date.add / DateHelper.php doesn't work for me


I am unable to use the Date.add function.

test = ${Date.add(Date.create('today'), '2 days')}

Doesn’t work.
I have to edit the file DateHelper.php (Neos.Eel)

     * Add an interval to a date and return a new DateTime object
     * @param \DateTime $date
     * @param string|\DateInterval $interval
     * @return \DateTime
    public function add($date, $interval)
I added this line -->
        $interval = date_interval_create_from_date_string($interval);
        if (!$interval instanceof \DateInterval) {
            $interval = new \DateInterval($interval);
        $result = clone $date;
        return $result->add($interval);

Does the date.add function work for anyone without date_interval_create_from_date_string() ?

Thanks in advance

You have to follow the syntax outlined here:


in your case: P2D

I find the idea to support the string syntax you used nice as well, but then that would be breaking. We might add it as separate method.

Hi Christian,

Thank you very much for your fast and professional answer. I probably wouldn’t have found the solution even though I had been reading the PHP manual all day today. It finally worked, I’m very happy about that.

btw Date.create('+2 days') should work, too
