Hello list,
I'm trying to learn and get comfortable with HTML forms in PHP. In one
example I am trying to include a file upload in one of the forms. I can
connect to the database but for some reason the MySQL query string is bad.
I've been over this for a while now and I think the problem is with the
form. I was hoping to get the esteemed opinion of the list in where I may
be going wrong.
This code:
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd;
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=en lang=en

titleGuitar Wars - Add Your High Score/title
link rel=stylesheet type=text/css href=style.css /
/head
body
h2Guitar Wars - Add Your High Score/h2
?php
if (isset($_POST['submit'])) {
// Grab the score data from the POST
$name = $_POST['name'];
$score = $_POST['score'];
$screenshot = $_FILES['screenshot']['name'];
if (!empty($name) !empty($score)) {
// Connect to the database
$dbc = mysqli_connect('localhost', 'admin', 'secretsauce', 'gwdb')
or die('Cannot connect to database');
// Write the data to the database
$query = INSERT INTO guitarwars VALUES (0, NOW(), '$name', '$score',
'$screenshot');
mysqli_query($dbc, $query)
or die('Cannot insert query');
// Confirm success with the user
echo 'pThanks for adding your new high score!/p';
echo 'pstrongName:/strong ' . $name . 'br /';
echo 'strongScore:/strong ' . $score . '/p';
echo 'pa href=index.phplt;lt; Back to high scores/a/p';
// Clear the score data to clear the form
$name = ;
$score = ;
mysqli_close($dbc);
}
else {
echo 'p class=errorPlease enter all of the information to add
your high score./p';
}
}

$_SERVER['PHP_SELF']; ?

Results in this output:
Guitar Wars - Add Your High Score Cannot insert query
Assuming the first field is an autonumber you don't want to set it. Otherwise
every row you try to insert will have an ID of 0, which will be a unique index
clash after the first one.
But take note of what everyone else is saying. You should be getting the error
message when this happens which will tell you exactly what the problem is,
above and beyond Cannot insert query (which, btw, makes no sense at all :)).
