I have read about SQL injection, and I will be scrubbing the data
before searching but the search is only available after logging into
the system. No one who isn't logged in can even view the page :)
That couldn't be less relevant. Repeat after me... "Legitimate" users
can be malicious too. All data going into a SQL statement needs to be
escaped unless it's a hard-coded string. No exceptions. Ever.
I see what you are getting at, and I do plan to check the data before
searching the contents of the database, but I was hoping to get one
thing working at a time since I'm still learning all of this :)
Sorry to go on about it, but security is not something you add after
you've got it working - that leads to holes. You need to bake security
right in from the start.
