How do I give a text area max length in Php?

[JasMate]

Here is the code: ProductName varchar(50) NOT NULL default '',

The problem is people can still type in heaps of characters after the "50". I would like it to be so they can't type anymore after the "50". How do I do this?

Thanks for helping.

The only way you can do it with a textarea is using javascript.

Like iNod said you can't actually limit the textarea with php however you can validate the input after submission. It's just a bit better than storing only 50 charactors of the input and not telling the user.

if( strlen($_POST['textarea']) > 50)
{
    echo 'You entered too many characters!';
}
