ginerjm Posted August 25, 2017 Share Posted August 25, 2017 Assuming that the error message is coming from the code at "step 3", why is your fetch commented out? And - what is the point of the code at step 2??? Link to comment Share on other sites More sharing options...
cyberRobot Posted August 28, 2017 Share Posted August 28, 2017 What are you looking to do? Is this a registration / sign-up form? Is it to log in? If you're not doing so already, you need to look into password hashing. More information can be found here: http://php.net/manual/en/faq.passwords.php Assuming that the error message is coming from the code at "step 3", why is your fetch commented out? There's another fetch in the while loop. Link to comment Share on other sites More sharing options...
requinix Posted August 28, 2017 Share Posted August 28, 2017 Make sure you are not going to welcome.php directly or through a link. Have to use the form in form1.html to get there. Which isn't good, but that's how you have it set up for now. Link to comment Share on other sites More sharing options...
