verify text entered in textarea of form

[hingis_rules]

Is there a way to check to see if text was entered in a textarea of a form with either PHP or Javascript?

Thanks

you can use both.

with javascript:

if(FormName.textareaName.value == "") {
   alert("no value entered");
}

With php

// assuming method on your form is set to post
if(strlen($_POST['textarea']) == "0") {
   echo "No value entered";
} else {
   echo "value entered";
}

Ok, but what if someone just enters a line break or something like that. The above solution fails even though the text box is empty of text.

You can use trim() then use strlen() to verify, or you can use a regular expression to make sure they entered either a number and/or letter.
