Need HELP !

Hello

I have a resource login and registration here, but I do not know what is the function to block certain characters and color codes. I wonder what is the function that prevents the creation of accounts with special characters and colors.

Thank you.

probably use a regular expressions like so

  
username = 'whatever32$#@(*$59' 
if username:match('[a-zA-Z0-9]+') ~= nil then  
    print 'It is alright' 
else  
    print 'It contains illegal characters or is not long enough' 
end 
  

tested for syntax and functionality

the regex I used ([a-zA-Z0-9]+) means: allow any character in range of a-z, A-Z, underscores and 0-9 and require at least one of those with no maximum

Could add to this script code that prohibits the use of color codes?

Thank you.

string.find 

String: "#%x%x%x%x%x%x"

[uhm]

well that code I posted doesn't allow the # character, so it already does

[Dinossauro]

But how do I apply this script to the resource? It's not working.

[uhm]

nay dawg you obviously need to change the hardcoded values to shiz like guiGetText and instead of those prints you do the actual handling like draw a popup when its wrong and trigger your server side code to do sql shiz

What? O_o

I do not quite understand, I'm Portuguese, my English is not so good.

[uhm]

Okay, I shall formulate it so it is better to understand or translatable by a machine:

Indeed. The code I have posted won't work instantly. Because you must replace the values I have set manually by functions such as guiGetText. Instead of the lines where I put "print", you must put the actual handling. Such as showing a pop-up window when the check fails. And when the check succeeds, put code so your server does things like SQL "INSERT"-commands. If you are checking if the username is okay in a client-side script, you also must put a trigger for the code on the side of your server (server-side). Because you can not use SQL-commands directly on the client-side.

[Dinossauro]

You could replace these values ​​with any example?

Thanks...

Lua used patterns, not RegExr. It's not same.
