// book states that: "|| cannot be used to force a second statement to execute if the first fails."
// this is wrong, as shown in examples below.
// the actual difference is || has higher precedence than assignment operator and "or" has lower precedence.
// if you do "or", the result of file contents is frsit assigned to $html1 and then second statement is executed if $html1 is false.
// if you do "||" the result of whole expression (file_get_contens() || die1("cannot do");) is assigned to $html2

exampe 12-4, 4th edition |
in the 4th edition, in example 12-4, it should be
$connection = new mysqli($hn, $un, $pw, $db);
in otherwords, it should be like in 4th edition, example 12-3
$connection = new new mysqli($hn, $un, $pw, $db);
assuming of course that login.php has these variables set up ($hn, $un, $pw, $db)
otherwise, if example 12-4 is left as is currently, the book's reader cannot login. It'll say something like 'database not found'

Example 12-4 |
The combination of the smartytest.tpl file (Example 12-4) and Example 12-3 does not work as intended: deleting files does not work.
Since deleting (in Example 12.3) is only done after a test that will always fail, the file is never deleted.
The test fails because isset($_POST['author']) will never evaluate to TRUE.
This also holds for the other tests with 'title', 'category', etc., (but not for 'isbn').
The reason why this is the case is because, in Example 12-4, the only things that are posted are 'delete' and 'isbn'.
the part between the section tags should be changed to:
{section name=row loop=$results}
<form action="smartytest.php" method="post">
<input type="hidden" name="delete" value="yes">
<input type="hidden" name="author" value="{$results[row].author}">
<input type="hidden" name="title" value="{$results[row].title}">
<input type="hidden" name="category" value="{$results[row].category}">
<input type="hidden" name="year" value="{$results[row].year}">
<input type="hidden" name="isbn" value="{$results[row].isbn}">
<pre>
Author {$results[row].author}
Title {$results[row].title}
Category {$results[row].category}
Year {$results[row].year}
ISBN {$results[row].isbn}
<input type="submit" value="DELETE RECORD"></pre>
</form>
{/section}
I'm not knowledgeable enough about Smarty to say it is a bug in the current version, but I would be surprised.
