How to limit words in textarea?

[kilbey1]

Hi all,

I'd like the amount of words a user enters in a textarea box to not be greater than 75. Can you help?

Thanks,
Eve

Textareas dont have a MAXLENGTH attribute so you cant actually limit the number of characters a user could type in,so the only thing I can think of (and this is just a theory), you could use Javascript onChange()event to evaluate the contents of the textarea as the user types, count the spaces in the string and then alert the user when 75 spaces are counted. It would probably be a lot of work to accomplish this or use the same principal by validating the input upon submission. split the string into an array (split it by the space character) and then count the number of elements in the array. If the array has more than 75 elements, return false and let the user know that they have typed too many words in the box.

Use javascript, or the php strlen function:

if (strlen($var) > 75)
 {
    echo "Error: A maximum of 75 characters are allowed!";
 }

Nah, not characters, words.

This would not be possible without an extreme amount of coding.
