activate_(plugin) │ action-hook │ WP 2.0.0

Fires as a specific plugin is being activated.

This hook is the "activation" hook used internally by register_activation_hook(). The dynamic portion of the hook name, $plugin, refers to the plugin basename.

If a plugin is silently activated (such as during an update), this hook does not fire.

Usage

add_action( 'activate_(plugin)', 'wp_kama_activate_plugin_action' );

/**
 * Function for `activate_(plugin)` action-hook.
 * 
 * @param bool $network_wide Whether to enable the plugin for all sites in the network or just the current site. Multisite only.
 *
 * @return void

function wp_kama_activate_plugin_action( $network_wide ){

	// action...
}

$network_wide(true|false)

Whether to enable the plugin for all sites in the network or just the current site. Multisite only.
