  1. I found the error. I was missing the '$' in front of row in this part of the code in view_quotes.php: {row['quote_id']} fixed to {$row['quote_id']} Thanks again for helping me identify the issue.
  2. I did notice that. Here's what I see: http://localhost:8888/phpfortheweb/edit_quote.php?id={row['quote_id']} What's the fix for this?
  3. Here's the HTML after adding the snippet you included above: <pre>Array ( [id] => {row['quote_id']} ) Array ( ) </pre> <!doctype html> <html> <head> <meta charset="UTF-8"> <link rel="stylesheet" media="all" href="../css/style.css" /> <title>Edit a Quote</title> </head> <body> <div id="container"> <h1>My Site of Quotes</h1> <br /> <!-- BEGIN CHANGEABLE CONTENT --> <h2>Edit a Quotation</h2><p class="error">This page has been accessed in error.</p><hr /> <h3>Site Admin</h3> <p><a href="add_quote.php">Add Quote</a> <-> <a href="view_quotes.php">View All quotes</a> <-> <a href="logout.php">Logout</a></p> </div><!-- close container --> <div id="footer"> <p>Content © 2013</p> </div> </body> </html> I appreciate any help you can offer. Thanks!
  4. I haven't run the query using phpMyAdmin, but I copied/pasted the query from the edit_quotes.php file into the next exercise (delete_quote.php) and I was able to delete quotes: //Define the query. $query = "SELECT quote, source, favorite FROM quotes WHERE quote_id={$_GET['id']}"; if ($r = mysql_query($query, $dbc)) { //Run the query. $row = mysql_fetch_array($r); //retrieve the information. So, this would indicate that the query works, right? Why would it work in one instance (delete) and not another (edit)? I checked my DB user's privileges and it appears I have all privileges enabled... (that was just a wild guess). Thanks again for your help. I'm at a loss and I've stared at this for so long I feel like I'm locked up. ;-)
  5. I'm working my way through Chapter 13 and I'm unable to get my edit_quote.php page to work. The error message I'm getting is: I understand that the reason for this is that the script isn't getting a valid ID. I'm just not sure why. Here's my code. I've reviewed it line-by-line a few times, but I'm not seeing the problem: <?php define('TITLE', 'Edit a Quote'); include('templates/header.html'); print '<h2>Edit a Quotation</h2>'; //Restrict access to adminsitrators only. if (!is_administrator()) { print '<h2>Acess Denied!</h2> <p class="error">You do not have permission to access this page.</p>'; include('templates/footer.html'); exit(); } //Need the database connection. include('includes/mysql_connect.php'); if (isset($_GET['id']) && is_numeric($_GET['id']) && ($_GET['id'] > 0)) { // Display the entry in a form. //Define the query. $query = "SELECT quote, source, favorite FROM quotes WHERE quote_id={$_GET['id']}"; if ($r = mysql_query($query, $dbc)) { //Run the query. $row = mysql_fetch_array($r); //retrieve the information. //Make the form. print '<form action="edit_quote.php" method="post"> <p><label>Quote <textarea name="quote" rows="5" cols="30">' .htmlentities($row['quote']). '</textarea></label></p> <p><label>Source <input type="text" name="source" value="'.htmlentities($row['source']). '"/></label></p> <p><label>Is this a favorite? <input type="checkbox" name="favorite" value="yes"'; //Chec the box if it is a favorite. if ($row['favorite'] == 1) { print ' checked ="checked"'; } //Complete the form. print ' /></label></p> <input type="hidden" name="id" value="' .$_GET['id']. '" /> <p><input type="submit" name="submit" value="Update This Quote!" /></p> </form>'; } else { //Couldn't get the infomration. print '<p class="error">Could not retrieve the quotation because:<br/>' .mysql_error($dbc). '.</p> <p>The query being run was: ' .$query. '</p>'; } }elseif (isset($_POST['id']) && is_numeric($_POST['id']) && ($_POST['id'] > 0)) { //Handle the form. //Validate and secure the form data. $problem = FALSE; if (!empty($_POST['quote']) && !empty($_POST['source']) ) { //Prepare the values for storing. $quote = mysql_real_escape_string(trim(strip_tags($_POST['quote'])), $dbc); $source = mysql_real_escape_string(trim(strip_tags($_POST['source'])), $dbc); //Create the "favorite" value. if (isset($_POST['favorite'])) { $favorite = 1; } else { $favorite = 0; } } else { print '<p class="error">Please submit both a quotation and source.</p>'; $problem = TRUE; } if (!$problem) { //Define the query. $query = "UPDATE quotes SET quote='$quote', source='$source', favorite=$favorite WHERE quote_id={$_POST['id']}"; if ($r = mysql_query($query, $dbc)) { print '<p>The quotation has been updated.</p>'; } else { print '<p class="error">Could not update the quotation because:<br/>' .mysql_error($dbc) . '.</p><p>The query being run was" ' .$query. '</p>'; } }// No problem! } else { // No ID set. print '<p class="error">This page has been accessed in error.</p>'; } // End of main IF. mysql_close($dbc); //Close the connection. include('templates/footer.html'); //Include the footer. ?> Thanks!
