Question

得到以下错误：

警告：date（）期望参数2为long，字符串为 /home/users/2/catfood.jp-cybercat/web/academy/wp-includes/functions.php 在第112行

指向该行：

$datemonth = $wp_locale->get_month( $datefunc( 'm', $i ) );

上述行需要进行哪些更改才能解决此问题？

这是整个代码

function date_i18n( $dateformatstring, $unixtimestamp = false, $gmt = false ) {
global $wp_locale;
$i = $unixtimestamp;

if ( false === $i ) {
    if ( ! $gmt )
        $i = current_time( 'timestamp' );
    else
        $i = time();
    // we should not let date() interfere with our
    // specially computed timestamp
    $gmt = true;
}

$datefunc显然是php的日期方法的别名。如果是这种情况，那么您试图通过传递单个整数1-12来获取月份。如果不能这样做，则需要将时间戳传递给PHP的日期方法，然后根据您传递的属性，选项将返回以下数据。然后，您将它传递给wordpress locale get_month方法，该方法返回月份的名称。您需要重构代码，以便$ i不是for循环变量。如果你只是想让Jan-Dec做到

$i = 1;
$monthArray = [];

do {

    // Just push the months to an array and pass it to the view
    array_push($monthArray, $wp_locale->get_month($i);
    $i++;

} while($i < 13);

然后用它做你需要的。如果要从数据库获取记录，则需要在返回的模型中访问适当的值。否则你将传递一个数组对象。如果您正在访问模型，您应该这样做）

// Access the property that you intended to retrieve the month on.
$datemonth = $wp_locale->get_month( $datefunc( 'm', $i['published_at'] ) );

我添加了一个名为＆＃34;付费会员专业版的插件＆＃34;这个插件是用英文写的，我翻译成日文。有很多这样的代码：

<?php printf(__('課金 #%s ( %s )', 'pmpro'), $pmpro_invoice->code, date_i18n(get_option('date_format'), $pmpro_invoice->timestamp));?>

我尝试按以下方式更改这些代码：

时间戳），$ pmpro_invoice-＆gt;代码）;？＆gt;

我想这就是导致这个问题的原因。你觉得怎么样？

现在我再次下载了这个插件，没有问题。

感谢您帮助我。
