Breadcrumb NavXT 7.1.0

Posted by in WordPress > Plugins

Holy new settings export format Batman! This release features several improvements relating to settings, including a new JSON format for settings export and import, updated BCN_SETTINGS_FAVOR_* behavior, improved handling of CPTs that are added too late in the settings page, and fixing a bug in the old XML settings export and import features.

On the filter front, a new filter, bcn_before_loop, was added. Similar to the existing bcn_after_fill, this filter allows unique handling of the breadcrumb trail when multiple renderings are called on the same page. Unlike the bcn_after_fill and bcn_before_fill actions which are bypassed when bcn_display() is called without $forced = true, bcn_before_loop filter will run on every call to bcn_display().

In addition to fixing a bug caused by the introduction of namespacing in 7.0 in the old XML settings export and import routines, several other bugs were fixed. The options updating and adding routines were updated to explicitly set the autoload value, to prevent loading the backup settings option unless absolutely needed (during an ‘undo’ operation). Lastly, a bug resulting in a PHP error on term archives that don’t have an active term was fixed.

Updates to the BCN_SETTINGS_FAVOR_* Constants Behavior

Posted by in Announcements

Beginning with Breadcrumb NavXT 7.1, the behavior of the BCN_SETTINGS_FAVOR_NETWORK and BCN_SETTINGS_FAVOR_LOCAL constants are changing. Previously, while both would try to favor their respective settings (local vs network), the resulting settings did not differ significantly from the BCN_SETTINGS_USE_* counterparts. Since Breadcrumb NavXT 7.0 changed to storing only non-default settings to the database, it made sense to update the logic behind the two BCN_SETTINGS_FAVOR_* constants.

In Breadcrumb NavXT 7.1, BCN_SETTINGS_FAVOR_LOCAL merges the local site settings (stored in the database) into the network settings, which, in turn, are merged into the default setting values. This results in a behavior where non-default values for local site settings will override the corresponding network settings.

Similarly, in Breadcrumb NavXT 7.1, BCN_SETTINGS_FAVOR_NETWORK merges the network settings (stored in the database) into the local settings, which, in turn, are merged into the default setting values. This results in a behavior where non-default values for network settings will override the corresponding local site settings.

In summary, Breadcrumb NavXT 7.1 implements changes to the BCN_SETTINGS_FAVOR_* constants that make them behave in a more logical and useful manner.

Using the bcn_manage_options Capability

Posted by in Guides

Since version 6.5.0, Breadcrumb NavXT uses the custom capability bcn_manage_options to grant access to, and allow updating settings on the Breadcrumb NavXT settings page. By default, Breadcrumb NavXT tries to add this capability to the administrator role. However, some setups do not have an administrator role, and require the bcn_manage_options capability to be assigned to the appropriate role on that site.

The following code, when placed in a site specific plugin, adds the bcn_manage_options to the role ROLE:

function my_bcn_manage_options_cap_adder()
{
    $role = get_role('ROLE');
    if($role instanceof \WP_Role && !role->has_cap('bcn_manage_options')
    {
        $role->add_cap('bcn_manage_options');
    }
}
add_action('admin_init', 'my_bcn_manage_options_cap_adder');

Simply swap ROLE for the name of the role that needs access to the Breadcrumb NavXT Settings page.

Breadcrumb NavXT 7.0.2

Posted by in WordPress > Plugins

This is the second, and hopefully last, bug fix release of the 7.0 branch of Breadcrumb NavXT. In this release, the “Sorry, you are not allowed to access this page.” message when attempting to visit the Breadcrumb NavXT settings page has been fixed for the majority of users. Additionally, the behavior of the default setting instantiation was changed to allow bcn_settings_init to set the value of the following settings: Hhome_template, Hhome_template_unlinked, hseparator, and hseparator_higher_dim.

The permissions bug was due to the introduction of namespacing in adminKit 3.0, which caused a check against WP_Role to always return false (since it was looking in the wrong namespace), resulting in the bcn_manage_options capability never getting assigned to the administrator role. Note that this primarily affected sites that never had Breadcrumb NavXT 6.5.0 or 6.6.0 installed (i.e. new installs or updating from a version prior to 6.5.0). If your WordPress install does not have an administrator role, you will need to add the bcn_manage_options capability to the appropriate role in your install.

As always, you can grab the latest version of Breadcrumb NavXT from the Breadcrumb NavXT page.

Breadcrumb NavXT 7.0.1

Posted by in WordPress > Plugins

This is the first, and hopefully only, bug fix release of the 7.0 branch of Breadcrumb NavXT. This release features fixes to 4 bugs and 2 behavior changes for better resiliency to non-supported environments. As part of this, two different settings errors have been fixed/handled more gracefully (the get_value on string error and the int required string given error). A few tweaks were made to hopefully support PHP5.6 without error (this is untested so the minimum listed PHP requirement stays at 7.0). Additionally, the run level for the default settings generation was moved from 11 to 9000, this should avoid errors in the settings page caused by other plugins registering post types at priorities other than the default 10.

Lastly, in order to work around issues with 3rd party code that is not 7.0 compatible, the location that the bcn_settings_init filter is applied has been moved to the top of the setup_setting_defaults function. With this new location, 3rd party code can still add settings, however the default settings can no longer be modified.

As always, you can grab the latest version of Breadcrumb NavXT from the Breadcrumb NavXT page.
