説明
The RSS Feed checker looks through your blogroll for links with rss feeds and then stores the name and url of the latest article.
The Links RSS Enhanced widget then displays the latest links in descending order.
The idea for the widget comes from the blogroll widget on blogger.
Version 2.0 for PHP 8 and above only. Only tested on 6.9.
For earlier versions of PHP use Version 1.1
Technical section
The plugin will create an extra table in your wordpress database to store the latest feed updates,
this will be called links_rss with the prefix for your database e.g. wp_links_rss
A Cron (schedule) is created to run every 30 minutes and process links. Note that Cron in WordPress
depends on hits, your WordPress website receives. So playing with this plugin within an offline
environment (MAMP, XAMPP, WAMP etc.) without anyone or anything triggering the scheduling by
sending requests to the WordPress page won’t produce any results if you do not trigger it by
yourself.

インストール
インストール
- Upload all the files to a new directory in the
/wp-content/plugins/directory - WordPress の「プラグイン」メニューからプラグインを有効化
- Visit the RSS Feed Checker Settings to initialise Cron Job and Create Database tables.
- From Appearance section of the dashboard select widgets
- Drag the “Links RSS Enhanced” widget into your selected sidebar
- Enter caption and number of links to show
削除
Because the plugin adds in a database table, options and a cron job (schedule) you need to remove the plugin via WordPress rather than just deleting it in FTP
- プラグインを無効化します
- Delete the plugin
If you only deactivate plugin the setting and table will be kept, only the cron job will be disabled.
FAQ
-
Where are the settings?
-
The settings are in the links admin panel under RSS Feed Checker
-
Where do I enter the RSS feed details?
-
The location of the feed can be added into the “advanced” box of the add/edit link screen. To assist with this, an additional metabox has been added that you can turn on with the screen options at the top of the screen.
-
I have a lot of links will this overload my website?
-
Firstly, only the links with feeds are processed. The plugin runs every 30 minutes and you can control how long it will run for and how long it will wait for feeds to respond. The server load limit can be configured to stop the checker running if your server is busy.
-
How can I display the feed using a shortcode rather than the widget?
-
Use the following shortcode syntax.
[LinksRSSEnhanced count=”number”]
-
How can I open the links in another tab?
-
The widget and shortcode will add the target attribute to the link based on the target assigned to the link e.g. _blank, _top, _none
