So I was asked to add a captcha into a PHP page that someone created a long time ago. I’m terrible with PHP but I have done other programming so I’ve been trying to piece it together. Here’s the code I’ve got so far, when the captcha is entered correctly everything works fine, but if it’s entered incorrectly the page reloads with an error message as well as showing the correct message for an invalid entry below the error. Thanks for any advice!
The error is: Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /var/www/vhosts/tinypaws.org/httpdocs/adoptapp.php:53) in /var/www/vhosts/tinypaws.org/httpdocs/adoptapp.php on line 290
Here’s what I’ve got…
