Hello there! Usually websites come with a single database. However if you want to connect multiple databases, that’s also possible, but you would need to consult with a developer for more information as that is a custom solution.

Hi! Can you clarify what error message are you getting?

Hey there, can you clarify where you intend this script to help login?

your registration script was really helpful, thanks

Hi! Yes, you can connect your HTML form to your database using PHP code. You can find a guide on how to create the connection here and another more generic about PHP to MySQL connection here.
In order to create a database on Hostinger, simply follow this guide and then to see how to edit your WordPress in HTML in order to insert the form, check this tutorial.

Hi there, your MySQL password should be that of the database you’ve created. Due to security reasons we suggest to never reuse your passwords and have them different. If you need help changing your password have a look at our guide here.
As for the “host”, generally “localhost” should work, but if you’re not able to succeed with it, you can also try out “mysql”. I also suggest to check with our Customer Success team for more urgent assistance 🙂
