PHP Guestbook Spam comments, Stop!!!

[simy202]

Hi,
I just begin to learn PHP and would like to test my learning with a PHP Guestbook, But I have a question here: I have a PHP guestbook that is occasional hit with spam comments. Thus, I am setting up a question that you must answer to post your comments.

The input page is: input.htm and the output is: output.php.

Here is the portion of code in the form in input.htm(note the portion in bold):

Code: Select all

<form name="Entry" method="post" action="output.php">
                           <h2 align="center"><strong><font face="Georgia, Times New Roman, Times, serif">Hearts At Home Guestbook</font></strong></h2>
                           <p></p>
                           <p><strong><font face="Georgia, Times New Roman, Times, serif">Sign Guest Book</font></strong></p>
                           <h2><textarea name="comment" rows="11" cols="74"></textarea></h2>
                           <p><strong>Name:</strong></p>
                           <input type='text' name='name' value=''size='24' border='0'>
                           <li>Is fire hot or cold?:</li>
                           <input type='text' name='question' value='' size='24' border='0'>         
       <!--mark_town--><!--mark_mail-->
                           <p></p>
                           <input type="submit" name="send" value="Send to Guest Book" border="0">
       <input type="reset" name="reset" value="Reset" border="0">
       <input type="hidden" name="new_entry" value="true">
       <input type="hidden" name="localDate">
                        </form>
