Trying to bump the count_of_logons by 1 using this update.
Phpmyadmin shows the count staying at zero.
I think that this SET count_of_logons = 'count_of_logons + 1'
is not coded correctly, but I get no errors so can not tell.
Anybody have any ideas?
The table def has count_of_logons INT,
$sql = "UPDATE members
SET count_of_logons = 'count_of_logons + 1'
WHERE logon_id = '$logonid'
AND logon_pw = '$logonpw'
AND email_verified = 'Y'";
Why are you quoting 'count_of_logons + 1'? In any case, that's the problem.
'count_of_logons + 1' is a string. You are assigning it to an INT, so it must
be converted to a number. Strings which do not start with anything numeric
convert to 0. For example:
mysql> SELECT 'count_of_logons + 1' + 0;
+---------------------------+
| 'count_of_logons + 1' + 0 |
+---------------------------+
| 0 |
+---------------------------+
1 row in set (0.00 sec)
Leave out the quotes to get the expected result:
$sql = "UPDATE members
SET count_of_logons = count_of_logons + 1
WHERE logon_id = '$logonid'
AND logon_pw = '$logonpw'
AND email_verified = 'Y'";
