hi
i need to validate textarea of a html form using php
<textarea name="comments" cols="26" rows="3"
id="comments"><?php
echo($comments);?></textarea>
presently my php code to validate the text area is
if($comments == "" )
{
$error.="<br>Please enter your comments";
}
with this code if a user hits the space bar once or couple of times as a
matter of fact there are no characters entered by the user i do not want
this to happen, if a user simply hits the spacebar and does not type
anything i should be able to display an alert message.
please advice how i can change the above php code.
thanks.
