php - 如何获得树枝的天差

Question

• 如何获得与当天的天数差异。

• 发推文在：“2015-02-22 09:56:42”。

枝条

{% for key,value in data.about %}
{% set tweets_date=(value.tweetedAt|date).date("now").format('%a') %}
{% endfor %}

我也试过

{% set dd='now'|date('d-m-Y') %}
{% set tweets_date=(value.tweetedAt|date).dd.format('%a') %}

最后我尝试了，但它给出了错误：

哈希键必须是带引号的字符串、数字、名称或括在括号中的表达式（值“{”的意外标记“标点符号”

{% set difference = {{ date("m/d/Y") }}.diff(date(value.tweetedAt)) %}
{% set leftDays = difference.days %}

错误：

<span class="small light_grey">{{tweets_date}}</span>

Impossible to invoke a method ("date") on a string variable ("June 6, 2015 01:06") in AcmeBundle

• 如何从tweet_date几天前的形式中获得差异。

更新了我twig/extensions通过作曲家安装的项目

Answer 1

我试过这段代码，它可以工作。

{% set difference = date(value.tweetedAt|date('Y/m/d')).diff(date('now'|date('Y/m/d'))) %}
{% set leftDays = difference.days %}

Answer 2

您需要在对象上使用过滤器而不是方法。你需要使用time_diff过滤器：

{%set tweets_date=value.tweetedAt|time_diff %}

要使其工作，您需要首先通过 composer 安装 twig-extensions：

composer require twig/extensions

然后将其包含在带有适当标签的服务容器中：

services:
    app.twig.extension.date:
        class:        Twig_Extensions_Extension_Date
        tags:
             - { name: 'twig.extension' }

Answer 3

如果日期来自实体，您可以：

{{ entity.days }}

并在您的实体中实现：

public function getDays()
{
    return $this->date->diff(new DateTime)->format('%a');
}
