Recommended Posts



        //something was posted
        $d_name = $_POST['d_name'];
        $manner_death = $_POST['manner_death'];
        $place_death = $_POST['place_death'];
        $nok = $_POST['nok'];
        $rel_nok = $_POST['rel_nok'];
        $morgue_att = $_POST['morgue_att'];
        $tag_num = $_POST['tag_num'];
        $treatment = $_POST['treatment'];

        if(!empty($d_name) && !empty($manner_death) && !is_numeric($user_name))

            //save to database
            $query = "insert into data (user_id,d_name,manner_death,place_death,nok,rel_nok,morgue_att,tag_num,treatment) values ('$user_id','$user_name','$d_name'.'$manner_death','$place_death','$nok','$rel_nok','$morgue_att','$tag_num','$treatment')";

            mysqli_query($con, $query);

            header("Location: post.php");
            echo "Please enter some valid information!";

You failed to test the result of the call to 'query'.  If you do that you may get an error message that helps you out.  Plus - you don't do any validation of the inputs you are getting which means you can be saving bad data in your db.  You need to examine your inputs and try to then use prepare statements for your database interactions from now on.

Lastly - I suggest that you look up using the PDO interface rather than the old mysqlI one.

Rearranging your query to line up the fields with the values...

$query = "insert into data 
(user_id,       ???        d_name,   manner_death,   place_death    ,nok,   rel_nok,   morgue_att,  tag_num,  treatment) values 
('$user_id','$user_name', '$d_name'.'$manner_death','$place_death','$nok','$rel_nok','$morgue_att','$tag_num','$treatment')"; 

Whether you chage to PDO (recommended) or stay with mysqli, use prepared statements. Don't put data values into the query string.

Putting this line of code before you connect the database will get it to report mysql errors...
