Unfortunately, despite the best efforts of myself, the technical editor, the copy editor, the line editor, the proofreader, and despite the multiple revisions, errors still occur. This page lists all the errors found in the book since it went to print.
Note: errors are corrected in subsequent printings and therefore your particular copy may not contain all of the following. You may also be experiencing problems not caused by a mistake in the book. If so, you may find the solution to your problem by using the book’s corresponding forum. Significant changes in the technology will be addressed there and you can also find problems and solutions encountered by other readers.

| Chapter | Page # | Description | Date Added |
|---|---|---|---|
| 2: Security Fundamentals | 39 | At the top of the page, it suggests that Figure 2.8 is on the next page when it’s actually on the same page. | November 30, 2010 |
| 3: First Site: Structure and Design | 53 | In the last paragraph, the phrase “PDF scripts” in the fourth sentence should be “PDF files”. | September 5, 2011 |
| 3: First Site: Structure and Design | 55 | In a stunning oversight, the escape_data() function defined never actually gets used! The intention was for that function to be called in lieu of mysqli_real_escape_string() in the site’s code. Ugh! | January 3, 2011 |
| 3: First Site: Structure and Design | 56 | In Step 7, the order of the arguments to the mysqli_real_escape_string() function are in the wrong order. It should be:
return mysqli_real_escape_string ($dbc, trim ($data)); |
December 9, 2010 |
| 3: First Site: Structure and Design | 65 | In Step 7, the conditional should check if $this_page equals $v, not $k:
if ($this_page == $v) echo ' class="selected"'; |
December 9, 2010 |
| 3: First Site: Structure and Design | 70 | Steps 3 and 4 should be reversed, so that the database connection is included prior to the header. This will become relevant in Chapter 4, when the login system is instituted. | December 1, 2010 |
| 3: First Site: Structure and Design | 71 | The code in Step 10 should actually be
// $_SESSION['user_admin'] = true; |
November 9, 2010 |
| 4: User Accounts | 74 | The backslash preceding the first line of code shouldn’t be there. | November 29, 2010 |
| 4: User Accounts | 87 | In Step 9, the query should make use of the get_password_hash() function, not create_password_hash(). | November 30, 2010 |
| 4: User Accounts | 91 | The first bit of code should include a file named login.inc.php. | November 29, 2010 |
| 4: User Accounts | 97 | The prompt in Step 1 should say “text editor or IDE”. | August 28, 2012 |
| 5: Managing Site Content | 110 | The label for attribute value in Step 14 should be title. | January 11, 2011 |
| 5: Managing Site Content | 132 | Step 1 should say that the file being created is named view_pdf.php. | January 3, 2011 |
| 6: Using PayPal | 151 | The prompt in Step 1 should say “PayPal Sandbox Test Site”. | August 28, 2012 |
| 7: Second Site: Structure and Design | 166 | The first sentence under the caption “Product Tables” should begin “Six product-related tables…”. | May 20, 2011 |
| 8: Creating a Catalog | 211 | The code at the top of the page, as part of Step 4, should have one more closing curly bracket, which completes the conditional begun in Step 3. | July 19, 2011 |
| 8: Creating a Catalog | 224 | The two references to the get_sale_price() function should be just get_price(). | December 22, 2010 |
| 9: Building a Shopping Cart | 239 | The conditional in the ternary operator in line 4 of the code under Step 12 needs to be updated per the explanation in this forum posting. | June 23, 2011 |
| 9: Building a Shopping Cart | 245 | The conditional in the ternary operator in line 11 of the code needs to be updated per the explanation in this forum posting. | June 23, 2011 |
| 9: Building a Shopping Cart | 248 | The get_shipping() function ought not to apply number formatting to the calculated shipping. As written, if the shipping is more than $999 (which, yes, is unlikely but still…), the query that inserts the order into the database, which includes the shipping, will fail because of the comma used to break up thousands. Ideally the function should return an unformatted number (or just formatted to two decimals), leaving the view script to format it as needed. | August 28, 2011 |
| 10: Checking Out | 253 | Reports have it that Authorize.net has changed how they handle the creation of test accounts. According to one reader, now Authorize.net provides your API Login ID and Transaction Key online, after logging into the Authorize.net system (the information is not provided via email). | June 23, 2011 |
| 10: Checking Out | 289 | In the code for Step 4, the single quotation marks are missing around the array index in $_POST[‘cc_number’]. | April 2, 2011 |
| 10: Checking Out | 290 | The errors array referenced in Step 8 should be $billing_errors not $shipping_errors. | October 23, 2010 |
| 10: Checking Out | 298 | The response variable referenced in Step 10 should be $response not $post_response. | October 9, 2011 |
| 11: Site Administration | 342 | Step 4 should include $r = mysqli_query($dbc, $q); | February 22, 2011 |
| 11: Site Administration | 347 | Under Step 11, all five TH elements are incorrectly closed. | November 30, 2010 |
