哪里的年份过滤器Laravel收集

Question

我有一个带有“ created_at”属性的Laravel集合，我想按年份进行过滤，就像雄辩的那样：

<div class="white-container">
    <div class="container">
        <div>
            <ul class="firstthree">
                <li>
                    <img src="images/brush.svg" class="brush" alt="brush">
                    <p class="brush">Graphic Design</p>
                </li>
                <li>
                    <img src="images/wand.svg" class="wand" alt="wand">
                    <p class="wand">UI Design</p>
                </li>
                <li>
                    <img src="images/code.svg" class="code2" alt="code">
                    <p class="code">Front-end Dev</p>
                </li>
            </ul>
        </div>

        <div>
            <ul class="secondthree">
            <li>
                <img src="images/settings.svg" class="settings" alt="settings">
                <p class="settings">Back-end Dev</p>
            </li>
            <li>
                <img src="images/database.svg" class="database" alt="databases">
                <p class = "database">Databases</p>
            </li>
            <li>
                <img src="images/mobile.svg" class="mobile" alt="mobile">
                <p class="mobile">Mobile Devices</p>
            </li>
        </ul>
        </div>
    </div>
</div>

但是在一个集合中。

谢谢！

$model->whereYear()

您可以使用“收藏夹”方法filter来查找年份符合您的条件的那些人：

$collection = Model::all();

$collection->filter(function ($value) {
    return $value->created_at->year === 2019; // assuming, that your timestamp gets converted to a Carbon object.
});
