Hi. I have a problem with my MySQLi insert syntax, here it is:

PHP Code:
$con dbcon(); //Open db connection
$result mysqli_query($con,"INSERT INTO `web_posts` (title_sk, date, owner, owner_id, category, category_id, content_sk, tags, show) VALUES ('".$postTitle."', '".timestamp()."', '".get_login()."', '".$_SESSION['user_id']."', '".$postCategory."', '".get_category_id($postCategory)."', '".$postText."', '".$postTags."', 'true')") or die(mysqli_error($con)); //Insert data to db
mysqli_close($con); //Close db connection 
MySQLi errors:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'show) VALUES ('Test test test!', '04.05.2014 16:18:43', 'admin', '1', 'News' at line 1
