datePost = 17-04-2015 今天= 06-05-2015

上面的例子返回它：-11

Answer 1

您必须编写自定义树枝扩展名

您必须使用以下代码编写一个twig函数，如here所述，通过php函数进行make diff：

$calcFrom = $from;

$calcTo = $to;
$now->diff($calcFrom)->format("%a")

并通过Twig extension提供。

如果您使用的是symfony2框架您可以使用KnpTimeBundle

在树枝上：这与当前日期进行比较：

{# Returns something like "3 minutes ago" #}
{{ time_diff(form) }}

这与另一个日期比较：

{# Returns something like "3 minutes ago" #}
{{ time_diff(form , to ) }}

希望这个帮助

问题已解决

{% set datePost = mat.data_criacao|date('d-m-Y') %}
{% set today = "now"|date('d-m-Y') %}
{% set difference = date(today).diff(date(datePost))%}
{% set leftDays = difference.days %}
{% if datePost == today %}
      1 day
{% else %}
    {{ leftDays }}
{{ endif }}

如何减去枝条中的日期？
