Download, unzip, and upload the `random-posts-within-date-range-widget` folder along with all its files to the `/wp-content/plugins/` directory. Activate the plugin through the ‘Plugins’ menu in WordPress. Go to the ‘Widgets’ page under ‘Appearance’ and drag an instance of the widget into the selected sidebar. Edit settings to meet desired effect. A few important notes: * If you click the “Always use current date as end point” box, it will override the “End Date” settings. (I had fancy JavaScript functions to validate/disable these menus, but ran into issues when running multiple instances of the widget. It’s on my to-do list for upcoming versions.) * Likewise, if you click the “Use time relative to current date” box, it will override the above date settings. * If the “Show Excerpt” box is checked and the post has a manual excerpt, WordPress will output the entire manual excerpt, regardless of what is entered in the “Excerpt Length” box. * If you check the “Show Excerpt” box and leave the “Excerpt Length” box blank or with “0” entered, it will use the default 55 words. The CSS of the widget can be edited much like any other HTML element. The structure is as follows: `TITLE DATE` `This can then be used as follows:` `have_posts() ){ $random_posts->the_post(); ?>`
