4,309 PointsPHP Token and AJAX
I have a static function call Token::generate(); that is needed when submitting forms.
As you can see the variable $token that is using my method to create my token.
Then you see the variable $hidden that is add the var to the form.
The problem is that if the user fails log in then the form will clear so they can enter there information with the errors that were created in the last attempt.
If the user attempts to try again with that token, it will not work because token has already been used.
Should I just create a php file that will just generate a token? Then I could use ajax to make a get request to obtain the token?
Would there be a better way?
if ($user->isLoggedin()) {
echo '<span class="profile-link"><a class="titles red-links" href="/' . $user->data()->username . '">' . $user->data()->username . '</a></span>';
} else {
$token = Token::generate();
$hidden = '<input type="hidden" name="token" value="' . $token . '">';
