how can I code so that only one letter can be used in a textarea

Question

I have a div and inside the div there is a textarea. But The problem is that I only want that when I will put in a word/letter I want to do so I only can put in like "1" or "A" and not "AA" or "11". Anyone got a code?

What language are you talking about? Can you show some code, please? — Dieter Meemken, Mar 18 '16 at 08:16

Use maxlength attribute

<textarea cols="30" rows="10" maxlength='1'></textarea>

In this thread you can find more options like jQuery validation: Limit number of characters in input field

If you need also to check at backend, then in e.g. php it will be like:

<?php

if (isset($_REQUEST['textfiledname']) && (strlen($_REQUEST['textfiledname'])     == 1) {
return true;
}
else {
return false;
}

?>
