How To Connect Database In WordPress With Example


To initiate a WordPress database connection, developers can utilize the wp-config.php file, which serves as the configuration file for their website.

For example:

/** The name of the database for WordPress */
define( ‘DB_NAME’, ‘brand’ );
/** Database username */
define( ‘DB_USER’, ‘root’ );
/** Database password */
define( ‘DB_PASSWORD’, ” );
/** Database hostname */
define( ‘DB_HOST’, ‘localhost’ );

define(‘DB_NAME’, ‘database_name’); defines the name of your specific database while define(‘DB_USER’, ‘username’); signifies the respective username associated with it. Additionally, specify define(‘DB_PASSWORD’, ‘password’); as well as define(‘DB_HOST’, ‘localhost’); where localhost refers to connecting through your local machine or alternatively an IP address can be used for remote connections. By following these steps diligently and entering accurate information within the wp-config.php file’s defined constants area pertaining to WordPress database connection settings; developers will establish a secure and reliable link that allows smooth interaction between their website’s content management system (CMS) and its underlying database infrastructure.
