How to connect to database

There's a dimension that must not be overlooked, and that needs to be taken into account. If at the outset you are looking for the server behavior palettes inherent in older versions of DW, this may possibly imply that you already have a site base, and that this one is likely to have been based on server behaviors...

If this is the case, if you use new extensions (DMX Zone as well as Webassist) or if you start working with Wappler again, or even if you develop your own code using MySqli (I personally prefer PDO, but that's another subject), you're bound to encounter artifacts between the old code and the new one... in my opinion, it would be wiser to go back to the old code and update it, whether from the new extensions, the new environment, or the new approach based on hand-coding.

If you now start a brand new project, everything remains green and open... it's up to you to move towards the environment that will suit you best, taking into account the comments made by everyone here on this forum.

Deep dive into server-side coding with PHP & MySQLi (improved):

Without the heavy lifting:

-- Wappler ~ Visual Web App Builder - https://wappler.io/

Hope that helps.

Since many versions now, Adobe has removed Server Behaviors from DW, so you wont have anymore access to UI Drag & Drop Database connexion, except if you run extensions from Drop Zone, Web Assist....

Well, beside giving the URL I wont be by any help, I never used them 😞
