Changing Previous/next links

-- HikaShop version -- :2.2.3 Business edition
-- Joomla version -- : 1.5.26
-- PHP version -- : 5.3.8

Hi,

Two questions about the previous/next links on top of the product pages.

1. Is it possible to show the name of the previous/next product instead of a button image?

2. How to change the ordering method of products used by the previous/next links?
The products in my categories are ordered alphabetical.
But the previous/next links use ordering by id. That's very confusing to the customers. These buttons link to the previous product in the id-order and the next product in the id-order.

I can't find a way to change this to have Previous linking to the previous product in the alphabetical order,
and Next linking to the next product in alphabetical order .

Udo

Hi Udo,
1. I think that you'll probably find your answer through this thread .
2. I don't think that you'll be able to change that without using some code customization.

Hi Mohamed,

Thanks for the reply.

1. I already read this thread. The code presented changes the prev/next buttons into the text Previous and Next.
My question is about changing .the buttons into the name of the previous product, and the name of the next product. So customers can see which product is linked to.
Is this possible?

2. Is the code customization difficult to do?
As it is now the prev/next links are of no use for me because for the customers there is no logic in the ordering.

Hi,

1. Anything is possible with the appropriate code. You would have to add the code:
$links->previous_product = $elt;
after:
$links->previous = hikashop_completeLink('product&task=show&cid='.(int)$id_previous.'&name='.$elt->alias.'&'.$pathway.$url_itemid);

and:
$links->next_product = $elt;
after:
$links->next = hikashop_completeLink('product&task=show&cid='.(int)$id_next.'&name='.$elt->alias.'&'.$pathway.$url_itemid);

in the file components/com_hikashop/views/product/view.html.php

and then change the code:
JText :: _('PREVIOUS_PRODUCT')
to:
$this->links->previous_product->product_name

and:
JText :: _('NEXT_PRODUCT')
to:
$this->links->next_product->product_name

in the file "show" of the view "product" via the menu Display>Views.
2. The ordering is not done based on the id but based on the ordering value of the products in the category. If you want to change that you'll have to edit the file components/com_hikashop/views/product/view.html.php and change the line:
$query='SELECT DISTINCT a.product_id FROM '.hikashop_table('product_category').' AS a LEFT JOIN '.hikashop_table('product').' AS b ON a.product_id=b.product_id WHERE '.implode(' AND ',$filters).' GROUP BY a.product_id ORDER BY a.ordering ASC';

to:
$query='SELECT DISTINCT a.product_id FROM '.hikashop_table('product_category').' AS a LEFT JOIN '.hikashop_table('product').' AS b ON a.product_id=b.product_id WHERE '.implode(' AND ',$filters).' GROUP BY a.product_id ORDER BY b.product_name ASC';

Thanks, Nicolas, works great, just what I needed.

Only one small disadvantage: after an update the changes in view.html.php get lost.
But it's a small effort to adjust the code again.

Udo

We'll add the lines in the view.html.php in the next version as this might be useful for others.
