Question

Maybe this sounds odd, but I have the feeling I am doing something wrong in my code. I did test it locally and it worked fine, however, when I try to send the data online, it doesn’t get entered into the database. I don’t know what I am doing wrong at the moment, and I can’t see the error (might have looked to much to the code or something like that). Sometimes a fresh look might help better.

The HTML:

<form method="post" class="signin" action="inc/actions/processing.php">
        <fieldset class="textbox">
            <label class="username">
                <span>Username</span>
                <input id="username" name="username" value="" type="text" autocomplete="off" placeholder="username">
            </label>
            <label class="charactername">
                <span>Charactername</span>
                <input id="charactername" name="charactername" value="" type="text" autocomplete="off" placeholder="Your character's first name">
            </label>
            <label class="password">
                <span>Password</span>
                <input id="password" name="password" value="" type="password" placeholder="Password">
            </label>
            <button class="submit button" name="RegisterUser" type="submit">Register User</button> 
        </fieldset>
  </form>

The PHP, processing part:

if(isset($_POST['RegisterUser'])){
        $Username = $_POST['username'];
        $Pass_nomdf5 = $_POST['password'];
        $Password = md5($Pass_nomdf5);
        $Charactername = $_POST['charactername'];       
        RegisterMember($Charactername,$Username,$Password);
        CloseConnection();
        header( "Location: http://" . strip_tags( $_SERVER ['HTTP_HOST'] ) . "/newHolo/" );
        exit;           
}

The PHP for the RegisterMember function:

function RegisterMember($Charactername,$Username,$Password){
    $query = "INSERT INTO User(CharacterFname,Username,Password) VALUES ('".$Charactername."','".$Username."','".$Password."');";
    SendQuery($query);
}

I ran it over quite a few times, but I have the feeling it’s a setting in my database that screws me. I switched all the NOT_NULLs to NULLs, except for the ID fields (see pic of database table below).

I am just not sure where my error is, cause locally it ran fine before i uploaded it. I did run though on an older version of PHP, and I have a feeling it might have to do with that as well. Can anyone help me out here?

Answer 1

As i stated above, it was an sql error that came back, and had indeed nothing to do with my code. I cleared the error message, when I noticed that I didnt fill in any data yet into the datafields of Sgroup.

 #1452 - Cannot add or update a child row: a foreign key constraint fails (darktide_newdarktide/User, CONSTRAINT User_ibfk_1 FOREIGN KEY (SgroupId) REFERENCES Sgroup (SgroupId))

Dumb, I should have known that if i have a constraint on a field, It should be at least filled with the data. So, i filled up that table, and voila, that did the trick. Thanks for your input people.
