Simple Captcha Script
Easy to add contact form captcha
How to add the captcha
is a script added to contact forms to help determine if a real human is submitting the info. It prevents bots from submitting your website forms and using them to send out spam emails through your website.
In our example above, if the correct number is entered in the form, you will be rewarded with a new number to enter. Exciting? Yes. But if you add this to your HTML form page it has a more practical use to prevent auto form submit bots.
You can edit the colors in the css code you'll add in step #1. The background is a two color gradient. You can freely experiment with the css styles.
Before you start
It is very important to do all 4 steps on this page, and also test your form
after you add the code below. Make backups
of your HTML page and CSS file before you start!
Step 1.) Add css code
Copy the following code and add it to the bottom of your CSS file like the "style.css" or "coolstyle.css". If you do not have a global css file you can add it to the <head> of your HTML page only
if you include <style type="text/css"> opening and </style> closing tags. View the source code of this page to see how it's used in the <head> section.
Step 2.) Add captcha box
Copy the following code and add it to the main body of your HTML page inside the form between the <form> start and </form> end tags. Add this code where you want the captcha box to appear, usually just above the <submit>
Step 3.) Add form function
The code in the box below is added to your <form> action line as in this example:
<form method="post" action="http://your-web-domain.com/cgi-bin/formmail.cgi" onsubmit="return checkform(this);">
View the source code of this page if you are not sure how to add the above code.
Copy the code below and paste it just after the end of your form. Paste it just after the </form> closing tag. Do not
add this code in the HTML page head section.

- Form is not working or looks broken: Try re-copying the code above and be sure you have copied every line of the code in the boxes.
