仅覆盖 WordPress PHP 函数的一部分

Question

我正在使用 Divi WordPress 主题，它通过一个函数在其 core.php 文件中添加 Google 字体。

PHP / WordPress 中有没有一种方法可以仅覆盖预先存在的函数的一部分？ 我想在我的子主题的 function.php 中添加一些内容，以便为 蒙特塞拉特数组。

当然，我可能会覆盖整个函数，但我希望有一种方法可以只编辑蒙特塞拉特数组，以添加更多权重选项。

这是添加一些预设权重的主题功能：

Answer 1

您可以使用“et_builder_google_fonts”过滤器：

将此添加到您的functions.php 以为Tangerine 字体添加额外的权重，例如：

add_filter('et_builder_google_fonts', 'my_custom_google_fonts', 10);

function my_custom_google_fonts($google_fonts) {

    $google_fonts['Tangerine']['styles'] = '300,400,700';

    return $google_fonts;

}
