Redux 框架 - 自定义字体过滤器

Question

我正在尝试将一组自定义字体传递给我认为是 Redux 框架上的 custom_fonts 过滤器，到目前为止，此设置返回错误：

Warning: Invalid argument supplied for foreach() in ....

我的过滤器：

add_filter('redux/theming/field/typography/custom_fonts', function ( $array ) {

  $array = array(
    "foo" => "foo font",
    "bar" => "bar font",
  );

    return $array;

});

Redux 核心似乎在通过时处理 custom_fonts：

if ( $this->field['custom_fonts'] !== false ) {
    $this->field['custom_fonts'] = apply_filters( "redux/{$this->parent->args['opt_name']}/field/typography/custom_fonts", array() );
    if ( ! empty( $this->field['custom_fonts'] ) ) {
        foreach ( $this->field['custom_fonts'] as $group => $fonts ) {
            $this->parent->font_groups['customfonts'] = array(
                'text'     => $group,
                'children' => array(),
            );
            foreach ( $fonts as $family => $v ) {
                $this->parent->font_groups['customfonts']['children'][] = array(
                    'id'          => $family,
                    'text'        => $family,
                    'data-google' => 'false',
                );
            }
        }
    }
}

原文件上面的代码：https://github.com/reduxframework/redux-framework/blob/188ddf5a5bd86314775f872553ad6af6f07b51ed/ReduxCore/inc/fields/typography/field_typography.php#L903

我的数据正在传递到过滤器，因为它试图通过 foreach 处理它，但不明白为什么它可能会中断。谁能弄清楚我可能遗漏了什么？

Answer 1

这是因为您return数组的格式有误。

试一试：

$array = array(
    "custom_fonts"=> [
        "foo" => "foo font",
        "bar" => "bar font",
    ]
);
