Hi there. Thanks for the video and information. Do you have a video where you create multiple instances of node-red for multiple projects on same server at once? :)
Hi, Thanks for the video. I was wondering if you had an opinion on data validation? By that in this example for the price parameter should we use a more comprehensive function within your convert to string OR is it better to catch the fail on conversion to a float? In either case we would need to notify the user that there is a problem with what they entered. We could either wait until they save (use this event to check) or once they leave the price entry field, but I'm not quite sure how to get that correct.
Thanks for watching! The first possibility that comes to mind would be to the function `node.send()` to return multiple objects; one for each table, for example. nodered.org documentation has more info on how that function can be used.
I'm not sure PHP would be the best tool to use here. Javascript would be the much better way to work in Node-RED with MySQL. Most MySQL actions can be done in Node-RED with no extra outside code required.
It allows injection attacks, be careful. I am searching ways to disable injection attacks but I don't find any with sql and node-red. If someone knows how, please tell me.
