php - 从自定义字段获取背景颜色？

Question

我正在使用来自 wordpress 的 Meta Slider，管理页面向 slider 添加了两个选项，即“标题”和“URL” 我想向字段添加“背景颜色”选项并具有 LI 类从字段中调用背景颜色。我该怎么做。

这是字段所在 slider 的 php，我如何以及在何处添加“背景颜色”选项。

另外，我要在 css 中添加什么以便它从后台字段调用？

Answer 1

 // localise the JS
        wp_localize_script( 'metaslider-admin-script', 'metaslider', array( 
            'url' => __("URL", 'metaslider'), 
            'caption' => __("Caption", 'metaslider'),

            /* ADD */'Background Color' => __("Background Color", 'metaslider'),

            'new_window' => __("New Window", 'metaslider'),
            'confirm' => __("Are you sure?", 'metaslider'),
            'ajaxurl' => admin_url( 'admin-ajax.php' ),
            'resize_nonce' => wp_create_nonce('metaslider_resize'),
            'iframeurl' => METASLIDER_BASE_URL . 'preview.php',
            'useWithCaution' => __("Caution: This setting is for advanced developers only. If you're unsure, leave it checked.", 'metaslider')
        ));

public function iframe() {
    wp_enqueue_style('metaslider-admin-styles', METASLIDER_ASSETS_URL . 'metaslider/admin.css', false, METASLIDER_VERSION);
    wp_enqueue_script('google-font-api', 'http://fonts.googleapis.com/css?family=PT+Sans:400,700');

    $link = apply_filters('metaslider_hoplink', 'http://www.metaslider.com/upgrade/');
    $link .= '?utm_source=lite&utm_medium=more-slide-types&utm_campaign=pro';
