minimum amount of words in text boxs

[echo@]

how can you set a minimum ammount of words for a textbox in indexu?

say 250 bare min for the description field?

<script>
function CheckLength()
{
var msg_area = document.getElementById("Message");
msg_area.innerHTML = "";
if (document.getElementById("comments").value.leng th < 20) {
msg_area.innerHTML = "YOU DID NOT ENTER ENOUGH INFORMATION";
}
else document.getElementById("testform").submit();
}
</script>

Modify to your requirements

these scripts only work if input type="button" not input type="submit".

indexu simply refuses to submit it the input type is set to button.

from what i can gather if the script was working with input type="submit" the user would recive the minimum ammount of character warning acordingly BUT the form would still submit anyway.

I have tried two scripts now but they require input type="button" to be enabled.

The next problem when i get this working will be knowing how to apply this to more than one <textarea>

are you looking for words or characters....???

if you are looking for characters, you can use javascript (getElementById) to test the length of field and change your onsubmit to return a true / false value. something like onsubmit="javascript:return ValidateMinFields(this)". Test as many fields as you like. If one fails the test, popup an alert message and the form is not submitted.

if you are testing for a minimum number of words, you will need to use the javascript split function instead of the length function.

then in the add.php/modify.php test the fields again using the PHP explode function to test for words or the strlen function to test for characters. (NEVER RELY SOLELY ON JAVASCRIPT TO VALIDATE A FORM). If they don't pass the test there, send the user back to the form with the appropriate message.
