                    - 20 submitted: last submission 05 Jun 2014

                    Page No.: 108 | Errata type: Code

                    In the "Index Controller" Section the file name should be IndexController.php instead of Index.php. Otherwise the autoloader will not find it.

                    Readers can also find the solutions for their errata at http://magedevguide.com/errata

                    Page No.: 25 | Errata Type: Technical

                    Under the definition for merging towards the top of the page, the second sentence should use branch instead of brand.

                    Page No.: 30 | Errata Type: Typo

                    There is an extra "the" under the third bullet point for "Controller"

                    It should be "The classes in this folder are meant to be abstract classes and extended by the controller class under the controllers folder"

                    Page No.: 40 | Errata type: Technical

                    Second bullet point should say "groups" not "group" since there is no "group" node in the provided code sample.

                    Page No.: 29 | Errata type: technical

                    The image at the bottom shows a typical Magento module folder structure. It should folder name as "Controllers" with a capital "C". It should be "controllers"

                    Page No.: 79 | Errata Type: Code

                    The second code snippet, 1st line of code says:

                    $productCollection->addAttributeToFilter('small_image', array('notnull'=>'','neq'=>'no_selection'));

                    should be

                    $productCollection->addAttributeToFilter('small_image', array('notnull'=>'','neq'=>'no_selection'))

                    There should be no semi colon at the end of the code line.

                    Page No.: 96 | Errata Type: Code

                    At the bottom of the page, bullet point 3:

                    app/code/local/Mdg/Giftregistry/Model/Entity.php

                    should be

                    app/code/local/Mdg/Giftregistry/etc/config.xml

                    Errata type: Typo | Page number: 92

                    In the bottom section the second step:

                    Create a new file called Type.php and copy the following content into the file (the file location is app/code/local/Mdg/Giftregistry/Model/Mysql4/ Type/Collection.php):

                    should be:

                    Create a new file called Collection.php and copy the following content into the file (the file location is app/code/local/Mdg/Giftregistry/Model/Mysql4/ Type/Collection.php):

                    Errata type: Code | Page number: 144

                    The first bullet states the location of the main.phtml template as:

                    app/design/adminhtml/default/default/template/customer/.

                    The location should read:

                    app/design/adminhtml/default/default/template/mdg/giftregistry/customer/

                    Errata type: Code | Page number: 81

                    In the section "Using Direct SQL", under "Reading" subsection, the description of `fetchOne` is incorrect

                    Quoting the source code's phpdoc at lib/Varien/Db/Interface.php, `fetchOne` fetches the first column of the first row of the SQL result.

                    Errata type: Code | Page number: 125

                    The edit.phtml file is like this:

                      <input type="hidden" id="type_id" value="<?php echo 
                    $loadedRegistry->getTypeId(); ?>" />

                    This field will not be posted without a name. If you update the edit.phml file like this it works:

                    <input type="hidden" name="type_id" id="type_id" value="<?php echo 
                    $loadedRegistry->getTypeId(); ?>" />
                                <input type="hidden" name="registry_id" id="registry_id"
                    value="<?php echo $loadedRegistry->getEntityId(); ?>" >

                    Errata type: Code | Page number: 125

                    At the bottom of the page there is a table with function can also be written as:

                    getModel()
                         |
                    getModelInstance()
                        |
                    getModelClassName()
                        |
                    getGroupedClassName()

                    Errata type: Code | Page no: 82

                    The line: $read = $resource->getConnection('core_write);

                    Should read: $write = $resource->getConnection('core_write');

                    Errata type: Code | Page no: 113

                    The line: if($this->getRequest()->getPosts() && !empty($data))

                    Should be: if($this->getRequest()->getPost()&&  !empty($data))


                    Errata type: Technical | Page number: 143

                    It reads: "We are setting the gridId; the default sort to be by eventDate, and we are enabling pagination and filtering."

                    Should be: "We are setting the gridId; the default sort to be by eventDate, and we are disabling pagination and filtering." 

                    Errata type: Code | Page number: 129 

                    The line: if ($searchParams = $this->getRequest()->getParam('search_params'))

                    Should be: if ($searchParams = $this->getRequest()->getParam())

                     

                     

                    The line: $this->getLayout()->getBlock('mdg_giftregistry.search.results')

                    Should be: $this->getLayout()->getBlock('giftregistry.results')

                    Errata type: Code | Page number: 119

                    The following step:
                    3. Add the following code inside the node (the file location is app/design/frontend/base/default/layout/mdg_giftregistry.xml)

                    Should be:

                    3. Add the following code inside the node (the file location is app/code/local/Mdg/Giftregistry/etc/config.xml)

                    Errata type: Code | Page number: 112

                    The function $this->getRequest()->getPost(), as used within newPostAction, >> editPostAction, and deleteAction, should actually be written as $this->getRequest()->isPost().

                    Errata type: Code | Page number: 114

                    The function deleteAction() must end with a call to $this->_redirect('*/*/'); Otherwise, the registry will be deleted as requested. The end must match the ends of newPostAction() (page 112) and editPostAction() (page 113)
