I’m posting this here as there doesn’t seem to be any documentation on how to do this. The WP e-Commerce plugin is a decent shopping cart plugin for WordPress, unfortunately it’s documentation is rather poor!
The breadcrumbs (once enabled via the settings in the admin panel) display a breadcrumb trail on your product pages. by default is looks something like this:
Store Name » Products Page » Category Name » Product Name
To edit the output you need to edit the function in the theme files. The function is:
<?php wpsc_output_breadcrumbs (); ?>
You can pass an array of arguments to the function. Your options are:
'before-breadcrumbs' => '<div class="wpsc-breadcrumbs">', 'after-breadcrumbs' => '</div>', 'before-crumb' => '', 'after-crumb' => '', 'crumb-separator' => ' » ', 'show_home_page' => true, 'show_products_page' => true, 'echo' => true
Now simply pass your arguments to the function, for example:
<?php wpsc_output_breadcrumbs ( array ( 'crumb-separator' => ' > ', 'show_home_page' => false, ) ); ?>
The above would display breadcrumbs with ‘>’ as a separator and removes the homepage:
Products Page > Category Name > Product Name
I also think its best to put your breadcrumb function in a separate file e.g ‘wpsc-breadcrumbs.php’ then include it in each instance:
<? include "wpsc-breadcrumbs.php"; ?>
This way you don’t need to edit it multiple times should you decide to change something in the future.
I hope this can be of help to someone!
The colours of your Web site are important because they will define the mood and emotions of your visitors as well as reflect your identity and image branding.
The huge array of plugins available for WordPress is one of it’s most appealing aspects. Unfortunately not all are cross-browser compatible especially with older versions of Internet Explorer.
