Question

Is it possible to show breadcrumbs based on the URL. For example if the user hits example.com it means home->test1->test and if user hits example1.com it means home->test2->test. Is it possible to control the breadcrumbs visibility. Any one guide me how to do this.

Answer 1

A very nice implementation of A very customizable breadcrumb can be found in the Zen theme. If you already use a sub-theme of Zen then you’re in luck. You;ll only probably have to configure it and you’re good to go.

1. Options for the breadcrumb: each theme has it’s own settings. So you’ll need to add the options you’ll want for youre breadcrumb (On/Off, separator, home link On/Off etc.) in a themes/your_theme_name/theme-settings.php file. Here you’ll find a starting point. For inspiration check out the theme-settings.php (for defining the options) and zen.info file (for providing the default values for the options).

2. Theme the breadcrumb: then you’ll have to implement your_theme_name_breadcrumb function in template.php. Again look in the file with the same name in the Zen theme for an example.

3. Showing the breadcrumb: last step is to make sure that your breadcrumb is visible and you do this by printing the $breadcrumb variable. Look in the page.tpl.php file template for the default implementation and customize it as you like.
