I'm using this code to limit max number of characters to a determined field... is it possible to force UPPERCASE?
Here's what I'm using:
add_action("wp_footer", "cod_set_max_length");
function cod_set_max_length(){
if( !is_checkout())
return;
?>
<script>
jQuery(document).ready(function($){
$("#cracha_empresa").attr('maxlength','33');
$("#cracha_primeironome").attr('maxlength','12');
$("#cracha_sobrenome").attr('maxlength','26');
// more fields
});
</script>
<?php
}
