counting characters

[prophoto]

I have a new project coming up which will require the form to count characters in a text area box in order to calculate total cost, how would I accomplish this?

ah missed the bit about the total cost, so your calculation element might have some PHP code as follows:

$costPerWord = 0.1;
$text = '{table___textarea}';
$words = explode(' ', $text);
$cost = count($words) * $costPerWord;
 
return $cost;

how would this work to count characters, not words?

Try ...

$costPerWord = 0.1;
$text = '{table___textarea}';
$cost = mb_strlen($text) * $costPerWord;
 
return $cost;
