Since Breadcrumb NavXT 3.5.0, two WordPress actions have been added into Breadcrumb NavXT. They are the bcn_before_fill and bcn_after_fill actions. As their names suggest, the first runs at the beginning of bcn_breadcrumb_trail::fill(), and the second runs at the end of the same function. Both actions pass a reference to the current bcn_breadcrumb_trail instance into the hooked function. This post quickly covers a use case for the bcn_after_fill action.
Believe it or not, Google has a rich snippits format for breadcrumbs. A user on the WordPress.org forums pointed it out to me. Is it cool? Sure. Is it useful? In its current form, probably not, and this is why.
If you are receiving an error similar to the following while activating Breadcrumb NavXT, please continue reading.
Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /wp-content/plugins/breadcrumb-navxt/breadcrumb_navxt_admin.php on line 53
This should be only caused by PHP4. The line of code PHP is failing on is protected $version = '3.5.1';. Specifically, it is the protected part that PHP4 does not know about, and subsequently chokes on. Some users have claimed to receive this in a PHP5 environment. If you receive this error, please insert
somewhere in your footer. Then, open up a page on your site and look in the output from phpinfo for your PHP version. If the version is not PHP5.2 or newer, please inquire with your webhost on how to migrate to a modern PHP installation. If the output states you have a version of PHP that is 5.2 or newer, please copy the output and e-mail it to me (full output). Feel free to provide an abridged output in the comments section of this page.
So today I received an email stating that a plugin of mine is featured in a book about WordPress—I wonder which one it was. After doing a little research I confirmed that the book does, indeed cover Breadcrumb NavXT—the email wasn’t very specific as to which plugin they were talking about, and I almost passed it off as spam.
The book is “WordPress and Flash 10x Cookbook” by Peter Spannagle and Sarah Soward. As the title suggests it covers WordPress and integrating flash elements into it (Yes, I find it odd that Breadcrumb NavXT is in it, but whatever). The section covering Breadcrumb NavXT is in chapter 2, and does a decent job representing it. Though, personally I would have elaborated a little more on it. In particular, I would have been a little more specific in the installation instructions—the provided instructions could lead to a different plugin being installed.
Unfortunately, with the fast pace of software development, the book is sort of out of date (not as bad as a WordPress 2.8 Themes book released this month by the same publisher). Luckily, Breadcrumb NavXT has not changed enough for the instructions in the book to be invalid or misleading. If you are looking for a book on WordPress and Flash you may want to check it out. You can pick up a copy from the usual place (Amazon).
With the first beta of WordPress 3.0 being available, it’s time to think about Breadcrumb NavXT once again. Currently, the SVN version of Breadcrumb NavXT works in WP 3.0. All versions of Breadcrumb NavXT prior to 3.5 (not released yet), have known bugs in WP 3.0.
As Breadcrumb NavXT 3.5 is already upping the minimum WordPress version to 2.8, support for custom post types won’t make this release. Some modifications to the core will be done to enhance extensibility for those who don’t want to use OOP techniques (e.g. filter/action hooks will be added). The first “beta” of this will be available, without updated translations, in the next two weeks. After a month of beta status, translations should be updated and a release in early May (will be moved up to be within a few days of the WordPress 3.0 release, if not before).
Breadcrumb NavXT 3.6 will require WordPress 2.9 as custom post type support will be added. Depending on the time available this release may have enhanced multi blog support. Currently, it looks like this will show up sometime in July.
Breadcrumb NavXT 3.7 will wrap up any multi blog support not covered in 3.6. Depending on how WordPress 3.0 and 3.1 turn out, this version may require WordPress 3.0. This will be a fall release, probably sometime in October.
