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"
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
   <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" />
   <h2>Guitar Wars - Add Your High Score</h2>

   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', '$score',
       mysqli_query($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">&lt;&lt; Back to high scores</a></p>';

       // Clear the score data to clear the form
       $name = "";
       $score = "";

     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" />

Results in this output:

Guitar Wars - Add Your High Score Cannot insert query

Thanks again for your help. This is an awesome list!


You should have your error settings set to show everything.
I include these three lines in all my development work:

ini_set('display_errors', '1');

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.
