Administration

The administration page is used to change the characteristics of the captcha system so that you may tailor it to meet your expectations, the admin page includes 5 important sections :

• Form properties (it's important to add the URL of your form only if you need the error message, which should be displayed to your visitor when  he incorrect security code, appears in the same page of your form)
• Captcha image properties : this section allow you to change the width, height , border and font of your turing image to fit your template.

• Error Alert properties : in this section you control how the error message which should be displayed to your visitor when he enters invalid security code, there are 3 options for how to show the error message :
  1. Error message appears in a new page generated by the form captcha , the error message you set appears on this page
  2. Error message appears in a new message you creates, in this case you need to generate a web page and type it's URL in the "generated error page".
  3. Error message appears in the same page of your form , in this case you need to add the following tag in your form page in the place that you want the error message to appear at :
  
  

  <!-- error alert goes here -->

   

• Success page: After processing the form normally the form possessor should direct your visitor to certain page where a thank you message displayed , Form captcha is not a form processor it only protect your form from automatic submission but however if you need it to direct your visitor somewhere after code verification you should check the "direct to success page" box and add the page URL in the "success page"

• Admin login info : setting the login info of the admin page , you shouldn't enter a password unless you want to change the existing one.
