wpgmp_shortcode_attributes

The wpgmp_shortcode_attributes hook in the WP Maps Pro plugin allows developers to customize the attributes for the [put_wpgmp] shortcode. It is triggered when the shortcode is processed, enabling the addition or removal of attributes dynamically.

Usage

Developers can implement this hook in their theme’s functions.php file or in a custom plugin. The hook provides the flexibility to modify the attributes of a map displayed using the shortcode, which can be particularly useful for tailoring the map’s behavior or appearance based on certain conditions.

Example 1

This example demonstrates how to change the limit attribute to show only 5 locations.

add_filter('wpgmp_shortcode_attributes', 'modify_map_limit');
function modify_map_limit($options) {
    $options['limit'] = 5;
    return $options;
}

Example 2

In this example, we add a new attribute to display maps from a specific category named “restaurants”.

add_filter('wpgmp_shortcode_attributes', 'add_category_filter');
function add_category_filter($options) {
    $options['category'] = 'restaurants';
    return $options;
}

Example 3

This example shows how to remove the show_all_locations attribute to prevent showing all locations by default.

add_filter('wpgmp_shortcode_attributes', 'remove_show_all_locations');
function remove_show_all_locations($options) {
    unset($options['show_all_locations']);
    return $options;
}

Remember to always validate and sanitize input data when modifying shortcode attributes to ensure security and prevent potential vulnerabilities.
