Re: Re: Re: Test if string is already quote()'d?by Seumas (Curate)

It's true that I do have a degree of control over things here in that all of the software code is written by my hand and my hand only - and that the input comes almost entirely from form-input by users.
Part of my intention here, however, was to decide whether I would have to force myself to always send quoted or non-quoted variables to my functions and stick with that practice, or if I could very easily write my functions so that they could say "oh, this is already quoted so I'll use it as-is" and "this one isn't quoted, so I'll quote() first before applying it into the SQL query".
Also, doing some quote testing would probably suck as I allow HTML in the input (it's an auction site).
Since I was finally able to refine my abstraction layer to something very simple when it comes to the INSERT and UPDATES, I've decided to stick with the practice of _NEVER_ quote()'ing anything. I'll just pass everything to my Auction::DB class and let it do the work (I know, I should have done this in the first place, but I was looking for a solution outside of putting it in my DB class since I wasn't quite ready to roll it out yet).
Here is the solution I have used:
I have an sqlInsert() method in my Auction::DB class:
Then I call it like this (by the way, I use PostgreSQL but this should work with most DBs):
Now, I never need to concern myself with quoting again. And yes, I know I should have just done this in the first place, but I was looking to tidy up my existing code separately from my transition to a mod_perl/OO based re-write of the site (which I am actually in the process of doing right now).
I also understand that Perl is a horrible first language and it's a really bad idea to make Perl your first introduction to object oriented coding. However, I started my software in Perl five years ago, that's what it's in now, it's what I know the best (so far) and it's more important to maintain/improve the software and the site as it is now than to rewrite a 16,000+ line program in an entirely different (and new to me) language.
Fortunately, I've had Perlmonks to refer to as a lot of the pitfalls and questions I've encountered during this transition to OO have already been asked by others. :)
