Fluid compare dates - typo3

Question

I want to compare two dates. I want to make a condition which checks if the date in my database is older than the date in two days.
Here are my two variables:
{<f:format.date format="d.m.Y">+2 days</f:format.date>}
{<f:format.date format="d.m.Y">{day.valid}</f:format.date>}
I want to solve this in the template, not in the model or the controller.

Answer 1

Assign your date to variable »yourdate«.
<f:if condition="{f:format.date(date: '+2 days', format: 'Y-m-d')} < {f:format.date(date: yourdate, format: 'Y-m-d')}">
<f:then>
yourdate is smaller than now + 2 days.
</f:then>
<f:else>
yourdate is greater than or equal to now + 2 days.
</f:else>
</f:if>

Answer 2

Here is my current solution which adds in a current date and does some calculations with the date from the content.
In the controller, add the current date to the data:
$this->view->assign('date_now', new \DateTime());
This is available as {date_now} in fluid then:
<f:if condition="{f:format.date(date: date_now, format: '(Y-m-d)')} > {f:format.date(date: '{event.date}-4 weeks', format: '(Y-m-d)')}">
<f:then>
<p>Event date is past</p>
</f:then>
<f:else>
<p>Event date is upcoming</p>
</f:else>
</f:if>
Note how on the right side, where some calculation is done, additional quotes and curly brackets come in ('{event.date}-4 weeks').
PS I prefer the Y-m-d format to U for a date comparison, as we don't want to compare the current time – just the date.

Answer 3

Convert the date to an unix timestamp using format="U" and compare them. You need to add a variable which contains the comparing date.
<f:if condition="{f:format.date(date: day.valid, format: 'U')} > {f:format.date(date: date_compare, format: 'U')}">
Date is valid
</f:if>

Answer 4

Actually: because DateTime has a getTimestamp method (http://php.net/manual/en/datetime.gettimestamp.php, since 5.3.0) which perfectly conforms to the supported getter method naming in Fluid, the following is perfectly possible. Given $date1 and $date2 are both DateTime instances assigned to the template:
<f:if condition="{date1.timestamp} < {date2.timestamp}">...</f:if>
Will compare the two dates as unix timestamp integers without the need to format the dates. So for your case, assign a $date = (new \DateTime('now'))->modify('+2 days'); from your controller action and compare to that in Fluid. Or just assign the time() timestamp and compare directly to that, skipping the DateTime usage.
