validate_plugin() WordPress Function
The validate_plugin() function is used to check whether a plugin is valid or not. This function is important because it helps to ensure that only valid plugins are installed on a WordPress site. The function takes two parameters: the plugin folder and the plugin file. If the plugin folder and file are both valid, then the function will return true. Otherwise, it will return false.
