Uploading photos has been a problem with Run Basic.
First it has to be at the root program, and not a RUNNED program.
You need some way of keeping track of your photos. That usually means maintaining a record for each photo. With this system you only need one photo ID for all your photos or data.
This system has always worked great for me, mainly because I run most of my stuff from a main menu. This makes it a RUNNED program and that's a problem.
This system solves several problems.
1. it can be run from a RUNNED program
2. It is one set of code that serves all your projects
2. You don't have to create a file to keep of each photo.
How it works.
Lets say you have a table called Equipment. You want to keep one or many photos of the equipment referenced by photoID.
The table may look something like this:
equipID varchar(10),
description varchar(30),
....
photoId varchar(20);
In the Equipment table you only need to create one photoID with something unique. For example the rowid. However when creating new records you don't have the rowid. So use maybe use something unique like time to nearest second:
t$ = time$()
hhmmss$ = left$(t$,2) + mid$(t$,4,2) + mid$(t$,7,2)
photoId$ = mid$(date$("yyyymmdd"),3)+hhmmss$
photoId$ = "X"+word$(photoId$+"_",1,"_") + "_"
This system looks for all photos that starts with that number. Therefore you can have as many photos as you like...
You need to create a project called "upload". This project takes care of uploads for all your systems.
You need to create a <iframe> in your code to run the photo program.
You pass information about your project, and directory to hold the uploaded photos, and how many photos are allowed.
