OpenCart Breadcrumb in header.tpl

Question

Can someone tell me how can I have the breadcrumb nav within the header.tpl and not in the product.tpl of opencart?

Answer 1

Due to the way 1.5.X is coded, you'll need to rewrite every controller and add a method back to the document class to allow passing from the product controller to the header controller. Is there any particular reason you want to do so?

Answer 2

I've just had to figure this out for a new site we're building and I've come up with the following; use at your own risk (I'll report back if I run into any major problems, but I can't foresee any... famous last words)

Basically the breadcrumbs are built in the controllers and we need the resulting $breadcrumbs array in the header controller. Modify system/engine/controller.php as follows:

[...snip...]
protected function render() {
    foreach ($this->children as $child) {
        $this->data[basename($child)] = $this->getChild($child,array('parent_data'=>&$this->data));
}
[...snip...]

This will send all the data in the parent controller, before render() was called, to every controller/method of the $children. Then we just need to pick this up in the header controller as follows:

<?php   
class ControllerCommonHeader extends Controller {
    protected function index($args=array()) {
        // parent data
        $this->data['parent_data'] = $args['parent_data'];
[...snip...]

And we can access everything in the template with $parent_data['whatever']. In this case, $parent_data['breadcrumbs'] will be the array of breadcrumbs that I can loop over with the code I've removed from each page.tpl and added to my header.tpl.

Answer 3

if all else fails just hack the css, something like

.breadcrumb {
   margin-left: -270px;
   margin-top: -65px;
}

will move the breadcrumb up and to the left.
