The settings for your WordPress theme are stored in the options database, in the wp_options table. This is where you can find the plugins stored. Depending on what you're trying to do, the query will be different. The add-on directory contains all the plugin files, but you won't usually need to modify them.
The data for each plugin is stored in the wp_settings table, with a prefix of cma_label_ or cmdm_ of the plugin abbreviation. The more options a plugin has, the more data WordPress needs to store, which may remain even after disabling the plugin and affect the look or functionality of the theme. The WordPress core is fully featured and customizable without having to include everything for everyone. Moving plugin data between two different websites can be difficult due to the IDs associated with each other as foreign keys. Any plugins available in the WordPress Plugin Directory can be installed through the built-in plugin installer.
To install, update or delete a plugin, all you need to do is add, change or delete a directory from there. MySQL is like the company that makes the cabinet that stores all the data of your WordPress plugins. Mu-plugins are add-ons installed in a special directory within the content folder and are activated automatically. If there are any static files such as CSS, JS or image files used directly by different plugins, they are stored in the plugins directory. If you have a copy of the plugin as a zip file, you can upload and install it manually through the Plugins administration screen. CreativeMinds offers a top-notch personalized WordPress service, ranging from site corrections to large-scale solution development.
There are thousands of add-ons available in the directory, so you're sure to find something useful. The if (function_exists ()) searches for the add-on and will only call the plugin function if it's installed and active.
