Hi guys.
Ive developed a site and now I've come to the stage where I need to
test each textfield on each form for illegal characters that have been
inputted.
I would like to know from some of you how you go about it?
Do you use a regular expression and test each textfield sequencially,
also what do you do when you find illegal characters? do you strip
them out of the inputted information or do you post an error message
and tell them that there are illegal characters?
I have many pages and many textfields so I would like to use the best
and most appropriate and time effective approach by taking in your
suggestions before doing the testing and counter measure.
Thanks in advance
Be more specific about what you mean by "illegal" characters. Give us
some examples.
Well any kind of character that could break the the site and the SQL statement. Its not really important what the characters are inputted but rather how to remedy the situation once these characters
have been entered.
Thanks
