So I know about MySQL injection and always escape all my user input before putting it in my database. However I was wondering, imagine a user tries to submit a query to inject, and I escape it. What if I then at a later moment take this value from the database, and use it in a query. Do I have to escape it again?
I’ve been trying to make a code that prompts the user to enter a minimum value and a maximum value in order to return a random value from the interval of those two. It’s been hours now, and I can’t really understand what I’m doing wrong. Also forgive me, I’m a student, so I’m still trying to understand these basic stuff.
so I am creating this table where I take the attendance of someone. I did a table when I show the players and give them false values by default. So I want to it be when you can select only one of the option, the person is present, missing, injured, sick or late.

I would like the user to upload a .csv file, and then have the browser be able to parse the data from that file. I am using ReactJS. How would this work? Thanks.
Is there a catchall function somewhere that works well for sanitizing user input for SQL injection and XSS attacks, while still allowing certain types of HTML tags?
Many of us need to deal with user input, search queries, and situations where the input text can potentially contain profanity or undesirable language. Oftentimes this needs to be filtered out.
I have a site where users can post stuff (as in forums, comments, etc) using a customised implementation of TinyMCE. A lot of them like to copy & paste from Word, which means their input often comes with a plethora of associated MS inline formatting.
Here is the code :
I’m working on a contact book application to improve my python skill, so far I’ve created functions to add new contact, view existing contact, but I’m stuck on a function to edit them, I don’t know how to tackle this task (note that editing and adding information is based on user input), currently the only information this application is recording are name, phone number and/or email (if user entered an email).
