我正在为wordpress制作插件-对此我还很陌生-但我正在尝试制作显示来自不同来源(CNN,The Onion,MOZ等)的供稿的信息中心小部件。我已经设置了插件我从https://jeremyhixon.com/tool/wordpress-option-page-generator/获得了自定义选项页面,一切似乎都正常运行。我的问题是-如何从选项页面中获取值并将其添加到我的小部件代码中。以下是具体选项:
进纸标签资讯提供网址文章数
/*
* Retrieve this value with:
* $dashboard_feeds_options = get_option( 'dashboard_feeds_option_name' ); // Array of All Options
* $feed_label_0 = $dashboard_feeds_options['feed_label_0']; // Feed Label
* $feed_url_1 = $dashboard_feeds_options['feed_url_1']; // Feed URL
* $number_of_articles_2 = $dashboard_feeds_options['number_of_articles_2']; // Number of Articles
*/
这是我的小工具代码示例,其中洋葱作为供稿源
/** START The Onion Dashboard */
add_action( 'wp_dashboard_setup', 'onion_dashboard_add_widgets' );
function onion_dashboard_add_widgets() {
wp_add_dashboard_widget( 'dw_dashboard_widget_onion', __( 'The Onion', 'dw' ), 'dw_dashboard_widget_onion_handler' );
}
function dw_dashboard_widget_onion_handler() {
$feeds = array(
array(
'url' => 'https://www.theonion.com/rss',
'items' =>15,
'show_summary' => 1,
'show_author' => 0,
'show_date' => 1,
),
);
ob_start(); // start output buffering
wp_dashboard_primary_output( 'dw_dashboard_widget_onion', $feeds );
$buffer = ob_get_clean(); // get the buffer without printing the content
// add the target attribute to the a-tag:
$result = str_replace("<a class='rsswidget'",
"<a class='rsswidget' target='_blank'", $buffer);
echo $result;
};
/** END The Onion Dashboard */
总结-如何将在选项页面中输入的值纳入此代码,以使某人可以轻松地将多个仪表板小部件添加到他们的网站?一如既往-预先感谢您帮助我解决这个问题!
我会使用get_option
,您可以在这里找到更多信息:https://developer.wordpress.org/reference/functions/get_option/。基本想法是这样的:
// from your plugin
$example_option_value = get_option('example_option_key');
// do something with $example_option_value
