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">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Guitar Wars - Add Your High Score</title>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<h2>Guitar 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 '<p>Thanks for adding your new high score!</p>';
echo '<p><strong>Name:</strong> ' . $name . '<br />';
echo '<strong>Score:</strong> ' . $score . '</p>';
echo '<p><a href="index.php"><< Back to high scores</a></p>';
// Clear the score data to clear the form
$name = "";
$score = "";
mysqli_close($dbc);
}
else {
echo '<p class="error">Please enter all of the information to add
your high score.</p>';
}
}
?>
<hr />
<form enctype="multipart/form-data" method="post" action="<?php echo
$_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="MAX_FILE_SIZE" value="32768" />
<label for="name">Name:</label>
<input type="text" id="name" name="name" value="<?php if
(!empty($name)) echo $name; ?>" /><br />
<label for="score">Score:</label>
<input type="text" id="score" name="score" value="<?php if
(!empty($score)) echo $score; ?>" />
<br />
<label for="screenshot">Screenshot:</label>
<input type="file" id="screenshot" name="screenshot" />
<hr />
<input type="submit" value="Add" name="submit" />
</form>
</body>
</html>
Results in this output:
Guitar Wars - Add Your High Score Cannot insert query
Thanks again for your help. This is an awesome list!
Tim
You should have your error settings set to show everything.
I include these three lines in all my development work:
error_reporting(E_ALL);
ini_set('display_errors', '1');
set_time_limit(2);
In this case, I do think that your insert statement is incorrect - I
could be wrong. I think the VALUES clause s/b just 'VALUE'. Also if
you added MYSQLI_ERROR to your error handling you should get a very
helpful message.
