This guide explains what the "MySQL prefix" option in a site's parameters is for and what the implications are for running your Web applications (CMS) and PHP scripts.

Definition

When the "MySQL prefix" option is enabled for a site, it is no longer necessary to add the prefix "wxyz_" in front of the name and the users of your MySQL database. A PHP script can therefore connect to MySQL with the user "myuser" and a database "mybase" and access will be automatic with the user "wxyz_myuser" and the database "wxyz_mybase".

Disabling the MySQL Prefix option

1. Open the admin console (https://login.infomaniak.com)
2. Go to Hosting
3. Click on the hosting/domain name concerned
4. On the hosting dashboard, under Sites, click on the domain name of the site concerned
5. Enable or disable the MySQL Prefix option
6. Make the necessary adjustments in the configuration files for your Web applications and PHP scripts

Implications and adjustments to be made

After disabling theMySQL Prefix option for a site, some PHP or CMS scripts may not work. In order to re-establish the connection to your databases, it is essential that you update the following information in the configuration file(s) of the scripts concerned:

• The name of the MySQL database
  • Before: mybase
  • After: wxyz_mybase
• The user of the MySQL database: the prefix of your server must be added
  • Before: myuser
  • After: wxyz_myuser
