没有任何错误时不会执行我的查询

Question

I have a login script in which I also execute a query to log when and from where people try to log in to my site. This little piece of code doesn't return any errors and the header works, but the query doesn't work for some reason. Does anyone have any idea what I'm doing wrong?

if($count==1){

$securityquery = "INSERT INTO security_kk (action,datetime,country,IP,Affected table,comment) VALUES (:action,:datetime,:country,:IP,:Affected_table,:comment)";
$q = $db->prepare($securityquery);
$q->execute(array(':action'=>"Login",
                  ':datetime'=>$datetime,
                  ':country'=>$country,
                  ':IP'=>$_SERVER['REMOTE_ADDR'],
                  ':Affected_table'=>"members",
                  ':comment'=>"Authenticated as ".$myusername));

$_SESSION['username'] = $myusername;
$_SESSION['privileges'] = $row['privileges'];
$_SESSION['email'] = $row['email'];
header("location:index.php");
}

I'm a beginner at PDO, but since there are no errors. I don't know where to look.

Answer 1

datetime is a data type in MySQL. Wrap that column identifier in ticks. Also, column identifiers with spaces in their name must be wrapped in ticks.

$securityquery = "INSERT INTO security_kk (`action`,`datetime`,`country`,`IP`,`Affected table`,`comment`) VALUES (:action,:datetime,:country,:IP,:Affected_table,:meta)";

Answer 2

Your error (or possibly one of the errors) is the difference between

:meta     // your query contains this

and

':comment'=>"Authenticated as ".$myusername;

Your array has no value for the placeholder named :meta

It doesn't hurt to check for errors using the error checking functions though, rather than having others try to figure out a simple typo.

while there aren't any errors

Because you aren't checking for them.

Answer 3

1. DateTime is a datatype of mysql.
2. check your Affected table column name - No space in column name

best way to use like below.

$securityquery = "INSERT INTO security_kk (action,[datetime],country,IP,Affected table,comment) VALUES (:action,:datetime,:country,:IP,:Affected_table,:meta)";
