Where Dynamic Page List is first mentioned on both pages |
The extension DynamicPageList (DPL) is mentioned but there are two extensions by that name: (1) DynamicPageList (Wikimedia) and (2) DynamicPageList (third-party).
I believe Mr. Barrett referring to the third-party version based on the code examples, but which extension he is referring to is not explicitly clear.
Note from the Author or Editor:
Since my book was published, a second extension has started calling itself DynamicPageList. My book documents the "third-party" DPL. The simplest way to fix this is:
- On page 278, first line, change the URL to http://www.mediawiki.org/wiki/Extension:DynamicPageList_%28third-party%29.
Page 125 already says DPL is a "third-party extension" so I don't think we need to correct anything here. |

First example on that page |
The example has one too many brackets. This is the text in the book:
'''[[dog]]]'''
This is what the text should be:
'''[[dog]]'''
Note from the Author or Editor:
The reader is correct. Change the triple bracket ]]] into a double bracket ]]

Second code sample |
This example does let superheroes edit in the Headquarters namespace, but it goes too far and also gives them all the abilities of sysops via the "editinterface" right. To fix this problem, replace the last five lines of code:
// Make namespace read-only except to those with the editinterface
// right, such as sysops
$wgNamespaceProtection[NS_HEADQUARTERS] = array('editinterface');
// Give superheroes the editinterface right
$wgGroupPermissions['superheroes']['editinterface'] = true;
with these six lines:
// Create a right unique to superheroes.
$wgGroupPermissions['superheroes']['mightmakesright'] = true;
// Only users with this right can edit pages in the headquarters namespace
$wgNamespaceProtection[NS_HEADQUARTERS] = array('mightmakesright');
// Optionally, give this right to sysops too (recommended)
$wgGroupPermissions['sysop']['mightmakesright'] = true;

The statement
-------------
If you don’t want any logo, set:
$wgLogo = false;
-------------
is not correct. This means to use the default logo.
Note from the Author or Editor:
The line of code should be changed to:
$wgLogo = '';

1rst paragraph |
"edit MediaWiki:Site notice"
should read
"edit MediaWiki:Sitenotice"
Note from the Author or Editor:
The reader is correct - this is a bad linebreak in the middle of a word. The term:
MediaWiki:Sitenotice
which is split across lines 1-2 of the page, belongs on a single line. |

Last line |
The book says that all extension code in the chapter can be downloaded and gives a book address, but there is no link at that address for the extension code. Is there some other location where we can get a link to this code?
Note from the Author or Editor:
The reader is correct. I will arrange with the editor (Mike L) to get these code examples posted. |

Example 15-2 |
In the definition of function ufUserVariable_Magic(), the second parameter, $langID , is passed by reference with an ampersand. However, in more recent versions of mediaWiki (I tried the code in Mediawiki 15.3) the second parameter must not be passed by reference - if you do, you get an error message and the wiki execution stops.
Note from the Author or Editor:
In example 15-2, in the line:
function wfUserVariable_Magic(&$magicWords, &$langID) {
remove the ampersand from &$langid, making it $langID. |

Example 15-5, function render() |
In trying example 15-5 with MediaWiki 15.3, I discovered that the example shows the 3rd parameter is passed by reference. This prevents the function from executing. Removing the & from the parameter making it pass by value allows the code to work in this version of MediaWiki. Two pages later, example 15-7 on page 297 correctly passes this parameter by value.
Note from the Author or Editor:
On page 295, example 15-5, in the fifth line from the bottom ("static function render..."), locate the word:
&$parser
and remove the ampersand (&) to make it:
$parser |

The very end |
The final paragraph should end with this additional sentence, if it will fit:
Message names must be lowercase.
just after the phrase "English, French, and Spanish." The word "must" should be emphasized in italics.
Note from the Author or Editor:
This is correct. If message names are not lowercase, the code will not work. |

code at bottom of page |
In the construct method, the call is made to
SpecialPage::SpecialPage('FancyForm');
This produces an error, at least with the latest svn version of MediaWiki
Fatal error: Call to undefined method SpecialPage::specialpage() ...
Sample code from http://www.mediawiki.org/wiki/Manual:Special_pages suggests the following type of construct method, which does work:
parent::SpecialPage('FancyForm');
There is a similar construct call on page 302.
I would guess that this may vary with different versions of PHP if this code worked in the past, but the parent:: call might be the best approach.
Note from the Author or Editor:
The line:
SpecialPage::SpecialPage('FancyForm');
should be changed to:
parent::SpecialPage('FancyForm'); |

Example 16-2 |
Example 16-2 uses the class 'SecureLoginPage' from Example 16-3.
All 3 times the class called incorrectly ('FancyForm' or 'SecureLogin').
Note from the Author or Editor:
1. The caption to example 16-2 should be changed from:
Example 16-2: SecureLogin.php
to:
Example 16-2: SecureLoginPage.php
2. Line 9 of example 16-2 should have the word FancyForm changed
to SecureLoginPage, and each of lines 10-12 need the word
SecureLogin changed to SecureLoginPage. There is one change per
line, for a total of four changes. The result should be:
$wgAutoloadClasses['SecureLoginPage']
= dirname(__FILE__) . '/SecureLoginPage_body.php';
$wgHooks['UserLoginForm'][] = 'SecureLoginPage::secureLogin';
$wgHooks['BeforePageDisplay'][] = 'SecureLoginPage::otherPage';
Changes to example 16-3:
1. The caption should be changed from:
Example 16-2: SecureLogin_body.php
to:
Example 16-2: SecureLoginPage_body.php

Index listing |
These two index entries under Symbols:
$wgAutoloadClasses, 285
$wgTitle, 300
should instead appear in index section "W", where all the other $wg... variables currently appear.
