Captcha Validation Always Fails
I am using only server validations, and for my captcha that was generated when I ran my from through CSS Form Builder is using the following kind of server validation:
Any Form Post
Server Variable: strtolower(((isset($_POST["securityCaptcha"]))?$_POST["securityCaptcha"]:""))
Same as: strtolower($_SESSION['captcha_Security_Code_1'])
checked not case sensitive
Does not seem to work. What's wrong here?
Attached is my code.
