Quick Restaurant Menu [erm_menu] Shortcode
The Quick-Restaurant-Menu shortcode is a powerful tool for displaying menus on your WordPress site. It allows customization of the menu’s appearance and content. The shortcode uses global post data to fetch and display a menu. It allows you to specify the ‘id’ of the menu, whether to show ‘thumb’ (thumbnails), the ‘price’ position, and if the price should be ‘inline’. If the post type isn’t ‘erm_menu’, it returns an empty string. The menu is then rendered using a template from the plugin’s directory.
Shortcode: [erm_menu]

Here is a list of all possible erm_menu shortcode parameters and attributes:
id– Unique identifier of the menu postthumb– Decides if thumbnails are shown or notprice– Determines the position of the priceprice_inline– Decides if price is displayed inline or not

The shortcode fetches the current day and time, checks against the rules set in the ‘erm_week_rules’ meta field for the ‘erm_menu_week’ post type. If the current day and time fall within the specified range, the menu for the day is displayed. If not, it returns an empty string.
Shortcode: [erm_menu_week]
