One of the main platforms for content publishing, generally running a site and developing themes and various plugins. However, to understand something, a bit of backstory is required to really know the inner workings of WordPress, the way the gears turn and all that jazz. This will better help us understand how certain things run and even error solving since we could trace down what the possible problem could originate from.
WordPress Directory Structure
Here we start of by looking at the structure when we install WordPress, various files are added, these can be divided into two types, the first is the main ‘WordPress directory” files and the other are as titled. Various website design and development in USA would teach the same elements in WordPress backend as these are the fundamentals when learning WordPress.
These files are directly related to the content being displayed in the WordPress admin panel which loosely translates to the backend of your site. You’ll see such elements as dashboard.php, options.php, widgets.php and users.php. From here, you can control how your site operates, who has access to it, the privileges to the people working on your site and other tools that you can add to it.
Over here, files such as plugin files, theme files and other media upload, your familiarity with the folder increases when you create a theme or plug-in on your own.
The heart of WordPress resides here. All the default settings, default functionalities reside here alongside default hooks, shortcodes that could be tracked to this very folder.
WordPress Load process
So when you load up WordPress, the file Index.php, this file is present in the directory so if you wanted to know where exactly the process starts from, its fro this file and you have to actually open it to look at the startup process. Then the WP_USE_THEMES is set to true from default, this indicates to WordPress to load the theme set for through the template hierarchy and to display it on the other elements of the page content, basically the face of the operation.
This element includes three aspects, the wp-load.php, calls wp() and template-loader.php. This initializes as a WP class object and the template-loader’s job is to initialize page templates but before all this starst, wp-load.php is the one that starts the whole process.
Certain paths are defined on this file, they are being constantly used in plugin and theme developments to make a reference to the root directory. The next step that it takes is to load the wp-config via the wp-load.php, in the scenario that wp-config does not exist within the directory that you’ll have to create one.
Finally, the last of the loading process, wp-config is involved in the installing of WordPress, this file would contain the database settings which h is the database username, the name and the password. The authentication leys generated for cookies, the database table prefix itself and the wp-setting.php.
The wp-settings is where all the workings occur, exploring this file is quite complex and has to be done in details since it contains quite important codes.
Well that sums it up, these are the elements behind work during the loading up of WordPress, each element has its important roles to play and to ensure WordPress works flawlessly and as you want it to be. There are a lot of other elements and origins of the codes used and developed for WordPress but that would be for perhaps, another time. If you want to further learn about WordPress, any WordPress development company in USA would gladly walk you through the process of WordPress works.
