Ml Slider [metaslider] Shortcode

The MetaSlider shortcode is used to embed a slideshow in a WordPress page or post. It accepts parameters like ‘id’, ‘title’, ‘restrict_to’, and ‘theme’. If ‘id’ or ‘title’ is not provided, it exits. If ‘title’ is given, it fetches the corresponding ‘id’. It also allows restricting the slider to a specific page or the homepage. If the specified slider is not found or not published, it returns a comment.

Shortcode: [metaslider]

Parameters

Here is a list of all possible metaslider shortcode parameters and attributes:

id – The unique ID of the MetaSlider.
title – The title of the MetaSlider, used to fetch the ID.
restrict_to – Limits display of the MetaSlider to specific pages.
theme – The theme applied to the MetaSlider.

Examples and Usage

Basic example – Displaying a MetaSlider slideshow by referencing its ID.

                $id = $wpdb->get_var(
                    $wpdb->prepare(
