quick-event-manager/quick-event-manager/legacy/quick-event-manager.phpQuick Event Manager [qem-calendar] Shortcode
The Quick Event Manager plugin shortcode is designed to display a calendar with events. It fetches and displays event data stored in the WordPress database, including event dates, titles, and descriptions. The shortcode also supports navigation through months and years, and allows filtering of events by category.
Shortcode: [qem-calendar]
Parameters
Here is a list of all possible qem-calendar shortcode parameters and attributes:
category– Filters the events displayed by categorynavigation– Toggles the navigation on/offmonth– Sets the calendar to a specific monthyear– Sets the calendar to a specific yearlinks– Toggles the event links on/offcategorykeyabove– Displays the category key above the calendarcategorykeybelow– Displays the category key below the calendarusecategory– Enables category filteringsmallicon– Adjusts the size of the event iconwidget– Adjusts the shortcode for widget useheader– Defines the HTML tag used for headersfullpopup– Enables a full-sized popup for eventscalendar– Enables calendar viewthisisapopup– Specifies that the calendar is in a popup
Examples and Usage
Basic example – Displaying the calendar with default settings
[qem-calendar]Advanced examples
Displaying the calendar with specific category and navigation settings. The calendar will only show events from the specified category and will not allow month-to-month navigation.
[qem-calendar category="music" navigation="off"]Displaying the calendar with a specified month and year. The calendar will start from the specified month and year.
[qem-calendar month="12" year="2022"]Displaying the calendar with links turned off and a small icon set to “trim”. The events will not be clickable and a small trim icon will be displayed.
[qem-calendar links="off" smallicon="trim"]Displaying the calendar in a widget, with a header set to h3. The calendar will be suitable for a widget area and the header of the calendar will be h3.
