Laravel call helper

Question

我在调用Laravel中的助手时遇到了一些问题。我有刀锋，里面有这个代码

@foreach ($sel->get_offers() as $o)
<option value="{{$o->get_date_range()->get_range()}}" {{($o->get_offer_key() == $u_key)? 'selected': ''}}>
@php
$select = $o->get_date_range()->get_start('j M D');
$change = str_replace(["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], [uctrans('labels.Monday'), uctrans('labels.Tuesday'), uctrans('labels.Wednesday'), uctrans('labels.Thursday'), uctrans('labels.Friday'), uctrans('labels.Saturday'), uctrans('labels.Sunday'), uctrans('labels.Jan'), uctrans('labels.Feb'), uctrans('labels.Mar'), uctrans('labels.Apr'), uctrans('labels.May'), uctrans('labels.Jun'), uctrans('labels.Jul'), uctrans('labels.Aug'), uctrans('labels.Sep'), uctrans('labels.Oct'), uctrans('labels.Nov'), uctrans('labels.Dec')], $select);  @endphp
{{$change}}
</option>                    
@endforeach

所以现在，我需要变量$change从刀片中删除并导入到helper (但仍然调用刀片)，如下所示

function translate_selects()
{
    $change = str_replace(["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], [uctrans('labels.Monday'), uctrans('labels.Tuesday'), uctrans('labels.Wednesday'), uctrans('labels.Thursday'), uctrans('labels.Friday'), uctrans('labels.Saturday'), uctrans('labels.Sunday'), uctrans('labels.Jan'), uctrans('labels.Feb'), uctrans('labels.Mar'), uctrans('labels.Apr'), uctrans('labels.May'), uctrans('labels.Jun'), uctrans('labels.Jul'), uctrans('labels.Aug'), uctrans('labels.Sep'), uctrans('labels.Oct'), uctrans('labels.Nov'), uctrans('labels.Dec')], $select);
    return $change;
}

如何在刀片/控制器中调用此帮助器？我没有在config/app.php中做任何更改。

Answer 1

您可以创建文件并将其命名为helper.php。

这个文件将不会有类或接口来实现它的功能。

然后在composer.json文件中，将helper.php路径放在files键中。

就像这样。

"autoload": {
    "files": [
        "app/helper.php" // full path here for your file
    ],
}

helper.php文件将是这样的。

<?php

function translate_selects()
{

$change = str_replace(["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun", "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], [uctrans('labels.Monday'), uctrans('labels.Tuesday'), uctrans('labels.Wednesday'), uctrans('labels.Thursday'), uctrans('labels.Friday'), uctrans('labels.Saturday'), uctrans('labels.Sunday'), uctrans('labels.Jan'), uctrans('labels.Feb'), uctrans('labels.Mar'), uctrans('labels.Apr'), uctrans('labels.May'), uctrans('labels.Jun'), uctrans('labels.Jul'), uctrans('labels.Aug'), uctrans('labels.Sep'), uctrans('labels.Oct'), uctrans('labels.Nov'), uctrans('labels.Dec')], $select);
return $change;
}

很高兴能让我知道你过得怎么样。

Answer 2

添加新的provide for Helper

artisan make:provider HelperServiceProvider

迁移到app/Providers/HelperServiceProvider.php

通过注册方法调用所有HelperFile

public function register()
{
    foreach (glob(app_path().'/Helpers/*.php') as $filename){
        require_once($filename);
    }
}

在providers配置/app.php中添加条目

'providers' => [
    'App\Providers\HelperServiceProvider',
]

现在您可以在任何地方调用自定义帮助器函数。
