../../acc/$id/info/ - this is the path with the data from the account
if the password and login do not match, everything is fine - it writes the "wrong password", but if I enter it correctly, it writes

    1 answer 1

    http-response headers cannot be sent after you have started outputting response body data. if your form code is displayed before the headers are issued, then nothing happens, you need to separate the data output and the condition check ie if you are successfully logged in, set $success=1; and later check if ($success) does not print the form.

    for the rest, the code is of course terrible, but if you are just learning, then ok.

    so we see that this is a code in a foreign language, why are you apologizing?

    • and where you need to put $ success = 1; when the page is updated, the variable will default to zero - BedOmar
    • when updating you, I understand, already in the cookie look, if set, then $ success = 1, otherwise 0; - strangeqargo
    • do you understand my cookies do not fall asleep as you see - BedOmar
    • doesn’t complain because the output happens before the cookies are posted, transfer it below - strangeqargo
