I am wondering what the best workflow would be to handle this process.
Basic steps are.
The user selects a csv file and uploads it.
The csv file is then checked against a set of rules.
If the csv file is invalid
The user is shown the rows that are invalid.
The user is given the choice to terminate the upload or, strip the invalid lines.
If the csv file is valid, or strip is clicked
The user is shown a screen to choose the filename.
If the filename is already taken the user is given the choice to
a) rename the file (to a name of their choosing)
b) replace existing file.
c) rename the file to filename_1 etc
When the name is chosen a table is created in the database called (csv_filename);
Then data from the csv is entered into the table.
The file is deleted.
The user is taken to a page showing the file data (from the table)
My issue is,
This is all run through ajax.
How do I handle reporting what file we are dealing with?
I dont want to pass back the filename in an ajax response as that is too easy to tamper with.
I dont want to create a table to hold the filepath and pass back an id, as it seems to be a waste to have a table for just this.
There are some issues with this, when the file is uploaded in the first step. Its done, its got a file name, and it can’t be terminated because its already there. It has to be, or how will you analyze it?
From the users perspective you can make it look like thats how its working, which maybe is what you meant.
Anyways, to report what file you’re dealing with, store it in a session variable.
