When installing WordPress for the first time on the localhost / server it presents forms and a step-by-step registration of a first user admin.
I would like to understand how I do a verification of these and how the system understands that it is the first installation.
I'm developing a mini-blog for the portfolio and would like to do exactly what Wordpress does when running for the first time.
The fundamental step WordPress uses to understand whether or not it is already installed is to look for the wp-config.php file, this happens in the file wp-load.php , around line 34 .
If it does not find this file in the allowed places (in the root of the site, a folder above the root), the system loads some functions and calls the file wp-admin/setup-config.php .
At setup-config.php it checks whether the wp-config-sample.php file exists, and from there, displays the form you see, starting with the screen to select a language.
