Move blockcart in new hook

[Vincent-31]

Hi,
 
I have created a new hook called "displayCartInBreadcrumb"  in the breadcrumb.tpl to display the link to the cart in every page of the template:

<div class="breadcrumb clearfix">
<a href="">{hook h='displayCartInBreadcrumb'}</a>
<a class="home" href="{$base_dir}" title="{l s='Return to Home'}">Accueil</a>
{if isset($path) AND $path}
<span class="navigation-pipe"{if isset($category) && isset($category->id_category) && $category->id_category == 1} style="display:none;"{/if}>{$navigationPipe|escape:'html':'UTF-8'}</span>
{if $path|strpos:'span' !== false}
<span class="navigation_page">{$path|@replace:'<a ': '<span itemscope itemtype="http://data-vocabulary.org/Breadcrumb"><a itemprop="url" '|@replace:'data-gg="">': '><span itemprop="title">'|@replace:'</a>': '</span></a></span>'}</span>
{else}
{$path}
{/if}
{/if}
</div>

There is the code in blockcart.php:

Actually, "hi there!" is well displayed in every page, but i am not able to display the link to the cart. 

 

Does someone know how to do it?

Hi

 

add this in your hook

return '<a href="'.$this->context->link->getPageLink('order').'" > CART LINK </a>';

It will return a link to the cart

Thanks Mohamadou for your reply.

 

In fact, i would like to add the link supplied by the custom block cart of the template, with an ajax behaviour (it displays the cart content when mouse si hover).

 

Any idea?

[Vincent-31]

I found a solution! In fact, it was only a css problem, if everything works great!
