Lab
9
This lab is to test your knowledge of being able to check user input data for errors and to lessen the possibility of a user entering malicious data.
The lab must contain several items. Your resulting output should like similar to this.
Modify the pages add.php and edit.php from the previous lab:
- Eliminate the possibility of a user entering malicious data. Do this by making a function that strips tags, strips slashes, and removes any whitespace from the ends of the string (trim). Punctuation will stay for this assignment, as names and addresses have punctuation in them..
- Check user input. Use regular expressions to do this.
- If the input does not pass the regular expression, create an error message stating this and do NOT add the record to your database.
- If the input did not pass, when the screen reloads, keep the original data in the textboxes so the user does not have to type everything back in.
Assignment is due 1 week from when it was assigned. 50% penalty if late.
