[Resolved] Limiting form submition characters

GenesisFusion

Here's my problem, I need to stop people from using characters other than standard english language characters, the reason for this is it is a game signup page, and the game server crashes if a character other than a standard english character is in a players name, I have no idea what language would do this, I'm totally lost at trying to do this, I dont even have the slightest idea where to start.

if (preg_match('%[^a-z]%i', $name_of_var))
  echo 'You entered something wrong';

[^a-z] means anything which is not in the range from a to z the i at the ends makes it case-independent so it will also mach capitals

Thanks alot, I'll use that, want any credits for this in my mod of the First Star Online client and server?

Have I made some sort of mistake...

if (preg_match('%[^a-z]%i', $char)) {
  echo 'You have entered incorrect characters in your characters name';
exit;
}

Because I tested it and incorrect characters still work.

mrhappiness

please do echo $char

above if (preg_match('%[^a-z]%i', $char)) {

echo $char;

so that i can see which illegal characters aren't found

GenesisFusion

Eh, its okay now... Never mind, I read it you said it wouldnt accept cap's so I just tried caps because i was too lazy, so i tried ¡è¡Â¦Å¦¨¡ì¦È and it stopped it... thanks for your help, much appreciated

GenesisFusion

One more thing if you have time, with character stats, I need it so say if they type 20 in one, it will say they have (so many points) left and it will limit the ammount they put in, is this possable also?
