Question

在我的Laravel 5.1应用程序中，我有一个Subscription功能。它在某种程度上起作用，但不是我想要的......

场景：用户在2016年10月订阅了6个月。所以，数组看起来像这样：

[
    "subscription_months" => 6
    "subscription_start_month" => "01-10-2016" // <-- will be carbon instance
    "subscription_end_month => "31-03-2017" // <-- will be carbon instance
    "monthName" => "October"
]

我展示的上述数组只有1个月..数组中还有5个元素..

我想要的是，我想在Year

之后附加monthName

所以，它看起来像这样。

[
    [
        "monthName" => "October, 2016" // <-- for 1st month
    ]

    [
        "monthName" => "November, 2016" // <-- for 2nd month
    ]

    [
        "monthName" => "December, 2016" // <-- for 3rd month
    ]

    [
        "monthName" => "January, 2017" // <-- for 4th month
    ]

    [
        "monthName" => "February, 2017" // <-- for 5th month
    ]

    [
        "monthName" => "March, 2017" // <-- for 6th month
    ]
]

到目前为止，我尝试过的代码是：

$startMonthForMixed = $invoice->subscription_start_date->month;

for($i = 0; $i < $invoice->subscription_months; $i++) {
    $convertedInvoices[] = [
        'id' => $invoice->id,
        'order_code'               => $invoice->order_code,
        'order_type'               => 'Mixed - Subscription',
        'subscription_months'      => $invoice->subscription_months,
        'subscription_start_month' => $invoice->subscription_start_date,
        'subscription_end_month'   => $invoice->subscription_end_date,
        'monthName'                => date("F", mktime(0, 0, 0, $startMonthForMixed, 01)) . ", " . Carbon::now()->addYear()
     ];
     $startMonthForMixed++;
 }

有人可以帮帮忙吗？提前谢谢。

Answer 1

您尝试过的代码将始终使用当前年份，因此如果订阅期限为另一年，则无法使用。

您可以在代码中使用此变体，这会使用一些Carbon和DateTime方法：

// take copy of start date
$subscription_month = $invoice->subscription_start_date->copy();

for($i = 0; $i < $invoice->subscription_months; $i++) {
    $convertedInvoices[] = [
        'id' => $invoice->id,
        'order_code'               => $invoice->order_code,
        'order_type'               => 'Mixed - Subscription',
        'subscription_months'      => $invoice->subscription_months,
        'subscription_start_month' => $invoice->subscription_start_date,
        'subscription_end_month'   => $invoice->subscription_end_date,
        'monthName'                => $subscription_month->format("F, Y")
    ];
    // move to first date of following month
    $subscription_month->modify('first day of next month');
}

Answer 2

您可以使用Carbon对象的add方法添加1个月来循环显示月数。然后，格式化只是调用format方法的问题，正如trincot已经提出的那样

根据条件显示月份和年份
