[PHP] Adding reCAPTCHA to form using PHP

[Ernie Kemp]

Need help with reCAPTCHA. Never installed it before.

When Submit is clicked the "quoterequest-redirect.php" is run but I think it
would be better to test the reCAPTCHA before the "quoterequest-redirect.php"
program has been run.

I check the CAPTCHA in "quoterequest-redirect.php", it displays a invalid
message if invalid but the user has to tab back to fill in the CAPTCHA
again.

 

The reCAPTCHA show correctly but I need some help/hints/tips here.

 

Thanks very much again,

..../Ernie
