currency format in laravel
提问by Johnny
I am using currency format in lots of places in my blade files. I am using number_format to show a proper currency format. So it looks like this
我在刀片文件的很多地方都使用了货币格式。我正在使用 number_format 来显示正确的货币格式。所以它看起来像这样
<p>${{ number_format($row->nCashInitialBalance, 2) }}</p> // ,123.00
<p>${{ number_format($row->nCashCalculatedBalance, 2) }}</p> // 0.50
<p>${{ number_format($row->nCashPaymentsReceived, 2) }}</p> // ,341.15
<p>${{ number_format($row->nCardFinalBalance, 2)}}</p> // 4.10
if I don't use it it looks like this
如果我不使用它，它看起来像这样
<p>${{ $row->nCashInitialBalance }}</p> // 23
<p>${{ $row->nCashCalculatedBalance }}</p> // 0.5
<p>${{ $row->nCashPaymentsReceived }}</p> // 41.15
<p>${{ $row->nCardFinalBalance }}</p> // 4.1
Also for the input fields I am using toFixed(2)in lots of places.
同样对于我toFixed(2)在很多地方使用的输入字段。
#nDiscount_fixed").val() = parseFloat( $("#nDiscount_fixed").val()).toFixed(2);
Isn't there an easiest way to show all the variables as proper currency format? I have used number_formatand toFixed(2)almost more then 50 times now.
没有最简单的方法将所有变量显示为正确的货币格式吗？我已经使用number_format和toFixed(2)几乎超过50倍了。

You could create a custom Laravel directive. You still need to call that directive at every place you need it but comes with the benefit that if you ever want to change the code (e.g. replace number_format with something else) you only have to update that directive.
您可以创建自定义 Laravel 指令。您仍然需要在每个需要的地方调用该指令，但它带来的好处是，如果您想更改代码（例如，用其他内容替换 number_format），您只需更新该指令。
Example (taken from the docs and updated for your use case) (in your AppServiceProviderbootmethod):
示例（取自文档并针对您的用例进行了更新）（在您的AppServiceProviderboot方法中）：
Blade::directive('convert', function ($money) {
return "<?php echo number_format($money, 2); ?>";
});
To use in in Blade:
在 Blade 中使用：
@convert($var)

You can add a custom Blade directivein the boot()method in your AppServiceProvider.phpfile.
您可以在文件的方法中添加自定义 Blade 指令。boot()AppServiceProvider.php
For example:
例如：
Blade::directive('money', function ($amount) {
return "<?php echo '$' . number_format($amount, 2); ?>";
});
And in your Blade file, you will just have to use @money()like this:
在你的 Blade 文件中，你只需要@money()像这样使用：
@money($yourVariable)
回答by Robert Kehoe
I would most not use a "directive"... I found it cleaner to do the same logic as an accessor on the model.
我最不会使用“指令”......我发现在模型上执行与访问器相同的逻辑更清晰。
public function getAmountAttribute($value)
{
return money_format('$%i', $value);
}

If you want to format negative numbers, you'll need to do it this way:
如果你想格式化负数，你需要这样做：
Blade::directive('money', function ($amount) {
return "<?php
if($amount < 0) {
$amount *= -1;
echo '-$' . number_format($amount, 2);
} else {
echo '$' . number_format($amount, 2);
}
?>";
});
In your blade file use:
在您的刀片文件中使用：
@money(-10)
If you make edits to your directive, you'll need to clear your view:
如果您对指令进行编辑，则需要清除视图：
php artisan view:clear
