Laravel Blade - 自定义助手 [英] Laravel Blade - custom helper

问题描述

我有很多数字的表格，我想对所有数字都使用数字格式.所以现在我有这个:

I have table with a lot of numbers and I want to use number format for all of them. So right now I have this:

<tbody>
    @foreach($table['float']['chips_amount'] as $float)
        <tr>
            <td class="no-border"></td>
            <td class="text-right chip-width">{{ number_format($float['chips']['value'], 0, ' ', ' ') }}</td>
            <td class="text-right count-width">{{ $float['count'] }}</td>
            <td class="text-right">{{ number_format($float['chips']['value'] * $float['count'], 0, ' ', ' ') }}</td>
        </tr>
    @endforeach
    <tr>
        <td class="no-border" colspan="3"></td>
        <td class="text-right value-width bold-border">{{ number_format($table['float']['amount'], 0, ' ', ' ') }}</td>
    </tr>
</tbody>

但我只是在重复相同的函数 number_format() 并且当有人决定格式会不同时可能会出现问题.然后我必须更改表格中的所有格式.我对 Nette 框架有一些经验，并且存在我可以拥有自定义助手然后在模板中使用它的选项，即: {{ $anyNumber|myCustomFormat }} 在管道之后我有自己的自定义助手.Laravel Blade 模板中有类似的东西吗?我在文档中没有找到任何关于此的内容.

But I'm just repeating the same function number_format() and there could be problem when somebody decide that format will be different. Then I have to change all formats in table. I have some experience with Nette framework and there exists option that I can have custom helper and then use it in template, i.e: {{ $anyNumber|myCustomFormat }} where after pipeline I have my own custom helper. Is there something like that in Laravel Blade templates? I didn't find anything about this in documentation.

推荐答案

您可以创建自己的刀片帮助文件.
创建您的文件(例如在 app/Helpers/bladeHelpers.php 中)并添加代码.例如;

You can create your own blade help file.
Create you file (say in app/Helpers/bladeHelpers.php) and add code. For example;

<?php
if (! function_exists('my_custom_number_formt')) {
    /**
     * Format number
     *
     * @param $value
     * @param $attribute
     * @param $data
     * @return boolean
     */
    function my_custom_number_formt($value)
    {

        return number_format($value, 0, ' ', ' ');

    }

}

然后将此文件添加到您的 composer.json 中的 autoload 部分(记得在 psr4 声明中根据您的项目设置命名空间)；

Then add this file to your composer.json in the autoload section (remember to set the namespace as per your project in the psr4 declaration);

{
... rest of file
"autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\": "app/",
            "MyApp\Custom\": "src/"
        },
        "files": [
            "app/Helpers/bladeHelpers.php"
        ]
    },
... rest of file
}

注意，此时您可能需要清除缓存.

N.B You may want to clear your cache at this point.

然后在你的刀片文件中使用；

Then use in your blade files;

<td class="text-right chip-width">{{ my_custom_number_formt($float['chips']['value']) }}</td>
