HomeBackend DevelopmentPHP Tutorial浅析Yii2 GridView 日期格式化并实现日期可搜索教程_PHP

Yii2

先给大家展示下日期格式化效果图,如果大家满意请继续往下阅读:

这个我们分情况讨论

1、如果你的数据库字段created_at存的时间格式是date或者datetime,那很简单,gridview中直接输出该字段created_at即可,如上图中右侧所示

2、如果数据库存入的时间戳类型,如上图中左侧所示,则需要像下面这样进行输出

[
'attribute' => 'created_at',
'value' => function ($model) {
return date('Y-m-d H:i:s', $model->created_at);
},
],
[
'attribute' => 'created_at',
'format' => ['date', 'Y-m-d H:i:s'],
],

以上展示了两种方式进行格式输出,都可以。但是,如果想要实现搜索的机制,如果你的数据库存入的是datetime型,很方便,dataProvider不用做修改,

代码如下

$query->andFilterWhere([
// ......
'created_at' => $this->created_at,
// ......
]);

如果你的数据库存入的是时间戳。

第一步,修改对应规则如下图所示

第二步,修改dataProvider可参考如下代码

//我们搜索输入框中输入的格式一般是 2016-01-01 而非时间戳
//输出2016-01-01无非是想搜索这一天的数据,因此代码如下
if ($this->created_at) {
$createdAt = strtotime($this->created_at);
$createdAtEnd = $createdAt + 24*3600;
$query->andWhere("created_at >= {$createdAt} AND created_at <= {$createdAtEnd}");
}

这里做个小总结,建议使用datetime类型,个人觉得存时间戳甚是麻烦,如果你有好的建议,欢迎给我留言,共同学习进步。在此也非常感谢大家对网站的支持!
