Working with Date

3:17 with Alena Holligan

Date can be used both as a filter and as a function. Because twig compiles to PHP, and Twig's date function returns a valid dateTime object, we can use PHP method calls on our date.

The date filter formats a date to a given format:

{{ post.published_at|date("m/d/Y") }}

The date function converts an argument to a date to allow date comparison:

{% if date(user.created_at) < date('-2days') %}
    {# do something #}
{% endif %}

Both the filter and the function may accept a timezone.

    Let's scroll down to the footer. 0:00
    To display the current year, 0:04
    we're going to use a filter, we're going to filter now. 0:07
    Now with a filter of date and I want to display the year. 0:12
    The date filter accepts two arguments. 0:20
    The first is our format and the second is a time zone. 0:23
    We don't have to specify time zone here. 0:27
    It will use the server time zone or the time zone we set up for our application. 0:30
    I just wanted the year, so we just use capital Y. 0:35
    Let's check that our year is still displaying. 0:39
    Great, still works. 0:42
    If you look at the documentation, 0:45
    date can actually be used as a filter or as a function. 0:47
    Let's give that a try. 0:51
    We're going to move our join down into our comments. 1:00
    And then we're going to add a conditional. 1:08
    {% if date() < 1:11
    date('2020-01-01')}. 1:15
    We can either pass a valid date or no date at all. 1:26
    This will use the current timestamp, which is the same as using now. 1:30
    Just like our filter, we have the option to pass a time zone as well. 1:34
    Next, we'll add an else, And our endif. 1:38
    For else, we'll use I can see clearly now. 1:50
    If our current date is before 2020, we're going to show a countdown. 1:57
    Because Twig compiles to PHP and Twig's date function returns 2:04
    a valid date time argument, we can use PHP method calls on our date. 2:09
    We use another command and 2:16
    we'll set the difference equal to 2:20
    date().diff(date('2020-01-01')), 2:26
    then we're going to display difference.days. 2:36
    Days until 2020. 2:44
    Lets check this out in a browser. 2:48
    Because I'm running this before 2020, I see the countdown. 2:51
    Twig is designed to be simple and easy to use for creating templates, but 2:56
    it also allows more advanced options and customizations. 3:01
    Before you go too crazy, keep in mind that Twig is meant to be used with views. 3:05
    Your view should focus on display, while keeping logic to a minimum. 3:11
