Hello,

How can i add a max character limit to a variable?

So if the var the user inputs is too long, it stops the procedure. else, continue.

Thanks in advance

PHP Code:

if(strlen($var)>$limit){
  echo('naughty boy!');
  exit();
}
else{
  ....
} 


Or in html, on the <input> tags, you have a "maxlength" attribute that specify the maximum number of characters the user can type.
