Breadcrumb - Active Link For Last Item

[radus]

Hi,

 

I wanted to have last item as hyperink in template breadcrumb

 

I had success for making it on Category and Subcategory if they were last pages, but not for Product page, which is like default [ no hyperlink ].

 

Below is the code; getPath modification to make page name breadcrumb as active hyperlink using page friendly url, is what I look for.

 

Thanks in advance.

 

/theme/theme/

 

<!-- Breadcrumb -->

{if isset($smarty.capture.path)}{assign var='path' value=$smarty.capture.path}{/if}

<div class="breadcrumb">

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"><a itemprop="url" href="{$base_dir}" title="{$shop_name|escape:'htmlall':'UTF-8'}"><img src="{$img_dir}icon/home.gif" height="18" width="18" title="{$shop_name|escape:'htmlall':'UTF-8'}" alt="{$shop_name|escape:'htmlall':'UTF-8'}" /></a></div>

{if isset($path) AND $path}

<span class="navigation-pipe">{$navigationPipe|escape:html:'UTF-8'}</span>

{if !$path|strpos:'span'}

<span class="navigation_page">{$path}</span>

{else}

{$path}

{/if}

{/if}

</div>

<!-- /Breadcrumb -->

Hi

i would like to add <strong> character on the last Item

May you help me please ?

[murtaza.dev]

Well, this is not a very active forum and prestashop lacks a serious documentation for developers. For your question, I somehow modified breadcrumbs for my project. You have to certain steps in order to add lastItem class to your breadcrumn

 

1. Override Tools.php to override/classes/Tools.php

2. Name your class "class Tools extends ToolsCore{ }"

3. Copy getPath function to your newly created Tools.php

4. Delete file from cache/class_index.php

 

Now that you have overrided that function, your can do whatever you want, specific to your question you can add lastClass to your item like this.

On line 61 or 62

 

Before

return $full_path.$path

 

After

if ($path) {
                   $item = $full_path . "<li class="lastItem"><a href="javascript:;">" . $path . "</a></li>";
               } else {
                   $item = "<li class="lastItem"><a href="javascript:;">" . $full_path . "</a></li>" . $path;
               }
               return $item;

 

Hope it helps.

 

Regards

Perfect thanks you very much !!!!

Just edit the " " to ' '

in your php code

[radus]

@ kevin78: good point ! is what I remember seeing at www.overstock.com and it was UX friendly

 

@ murtaza.dev: +1 +1 & many thanks

What about pages like 'sitemap'? The breadcrumb doesn't seem to be parsed through getPath on that page?

 

Seriously the way Prestashop generates breadcrumbs is retarded.

murtaza Thank you very much!

Hi,
 
I've managed to modify last element for categories and products thanks to murtaza's help, but when I go through my account, it does not work.
 
Code is:
 
<div class="breadcrumb">
   <a title="return to Home" href="http://www.dail-software.com/">Home</a>
       <span class="navigation-pipe"></span>
            <a href="https://www.dail-software.com/en/my-account">My account</a>
             <span class="navigation-pipe"> </span>
        Order history
</div>

 

and it should be:

 

<div class="breadcrumb">

    <a title="return to Home" href="http://www.dail-software.com/">Home</a>

    <span class="navigation-pipe"></span>

    <span class="navigation_path">

        <a href="https://www.dail-software.com/en/my-account">My account</a>

        <span class="navigation-pipe"> </span>

        Order history

    </span>

</div>

 

Can anybody help me?

 

Thanks
