Retrieve the name and a link from a specific category was created by neo191987

-- HikaShop version -- : 3.0.1

Hi want to ask how I can retrieve a name and a link to a specific category?
The task is the following:
In the product page should appear as follows: field name: name and link to the category. For example when I a product with category: Steam (Products (main) / Platform / Steam) to extract only the data for the category Steam. Thus to filter the products from this category only. I do not like the current system for Tags and use it as a substitute.
I urgently need this code.

Something similar to this code

Code:

<?php 
  foreach($this->categories as $category){
  $categoryClass = hikashop_get('class.category');
  $categoryClass->addAlias($category);
  echo '<a href="'.hikashop_contentLink('category&task=listing&cid='.$category->category_id.'&name='.$category->alias,$category).'">'.($category->category_name).'</a>';
  }
  ?>

Hi,

You had a typo in your code, I've fixed it for you.
Besides that, it's indeed that code that you want to add, for each in the file "show_default" of the view "product" via the menu Display>Views.
That will add a link to the listing of products of the categories of the product.

Hi, is it possible to extract information not for all categories but only for a category. For example if a product has a 5 languages to extract data from the Languages category without the other categories to which it is linked product. Generally speaking, my goal is to extract data from only one category that contains subcategories related to product.

Hi,

I'm not following you. This code only display the clickable category name of the categoreis related to the product, no other categories.
And if you want to filter out some categories of the list to only display one, sure that's possible. Just add the code to skip the categories you don't want based on your criteria.

Just this code I need. Can you check if there is any incompatibility with the new version of hikashop. I also want to ask can you make code with canonical url. Thanks in advance

Code:

<?php
	$url = JURI::base(true)."/index.php?option=com_hikashop&ctrl=category&task=listing";
	$productClass = hikashop_get('class.product');
	$categories = $productClass->getCategories($this->element->product_id);
	$categoryClass = hikashop_get('class.category');
        $bookCat = '';
        $writters = '';
	foreach($categories as $category){
		$categoryInfo = $categoryClass->get($category,true);
		$cid='';
		$name='';
		if(isset($categoryInfo->category_id) && !empty($categoryInfo->category_id)){
			$cid = "&cid=".$categoryInfo->category_id;
			$name = str_replace(' ','-',strtolower($categoryInfo->category_name));
			$name = "&name=".$name;
		}
		$item_id = '';
		global $Itemid;
		if(isset($Itemid) && !empty($Itemid))
			$item_id = "&Itemid=".$Itemid;


		if($categoryInfo->category_parent_id == '2') //replace it by the id of CATEGORIES cateogry
		    $bookCat .= "<a href='".$url.$cid.$name.$item_id."'>".$categoryInfo->category_name."</a> ";
		elseif($categoryInfo->category_parent_id == '2') //replace it by the id of WRITTERS category
		    $writters .= "<a href='".$url.$cid.$name.$item_id."'>".$categoryInfo->category_name."</a> ";
	}
        echo "<span class='listCategories'>".$bookCat."</span><br/>";
        echo "<span class='listWriters'>".$writters."</span>";
?>

Hi,

I see many problems with that code.
1. You already have the equivalent of $categories in $this->categories, so you don't need the code:

Code:

$productClass = hikashop_get('class.product');
	$categories = $productClass->getCategories($this->element->product_id);

2. The code

Code:

$name='';
		if(isset($categoryInfo->category_id) && !empty($categoryInfo->category_id)){
			$cid = "&cid=".$categoryInfo->category_id;
			$name = str_replace(' ','-',strtolower($categoryInfo->category_name));
			$name = "&name=".$name;
		}

is wrong, you should rather use the alias of the category as in the code I gave you.

3. Instead of manually prepending JURI::base(true) to the non-SEF URL, you should rather use the hikashop_contentLink function like in the code I gave you.

Basically your whole code should be converted to only:

Code:

<?php 
  $bookCat = '';
  $writters = '';
  foreach($this->categories as $category){
  $categoryClass = hikashop_get('class.category');
  $categoryClass->addAlias($category);
  if($categoryInfo->category_parent_id == '2')
    $bookCat .= '<a href="'.hikashop_contentLink('category&task=listing&cid='.$category->category_id.'&name='.$category->alias,$category).'">'.($category->category_name).'</a>';
  elseif($categoryInfo->category_parent_id == '2')
    $writters .= '<a href="'.hikashop_contentLink('category&task=listing&cid='.$category->category_id.'&name='.$category->alias,$category).'">'.($category->category_name).'</a>';
  }
  echo "<span class='listCategories'>".$bookCat."</span><br/>";
  echo "<span class='listWriters'>".$writters."</span>";
  ?>

The code in the other thread is more than 4 years old. at that time, the hikashop_contentLink function, the addAlias function or the $this->categories variable didn't existed.

Thanks for the correction. But now I have the following problem - not showing the name and links to the categories. This is all the code that I've entered:

Code:

<?php 
        $developers = '';
        $publishers = '';
        foreach($this->categories as $category){
        $categoryClass = hikashop_get('class.category');
        $categoryClass->addAlias($category);
        if($categoryInfo->category_parent_id == '15')
        $developers .= '<a href="'.hikashop_contentLink('category&task=listing&cid='.$category->category_id.'&name='.$category->alias,$category).'">'.($category->category_name).'</a>';
        elseif($categoryInfo->category_parent_id == '22')
        $publishers .= '<a href="'.hikashop_contentLink('category&task=listing&cid='.$category->category_id.'&name='.$category->alias,$category).'">'.($category->category_name).'</a>';
  }
  echo "<span class='list-developers'>".JText::_('Developer: ').$developers."</span><br/>";
  echo "<span class='list-publishers'>".JText::_('Publisher: ').$publishers."</span>";
  ?>

Maybe I missed something.

The categories to which I want to take the data are developers (id:15) and publishers (id:22).

The result is as follows

The old code

Code:

<?php
	$url = JURI::base(true)."/index.php?option=com_hikashop&ctrl=category&task=listing";
	$productClass = hikashop_get('class.product');
	$categories = $productClass->getCategories($this->element->product_id);
	$categoryClass = hikashop_get('class.category');
        $developers = '';
        $publishers = '';
	foreach($categories as $category){
		$categoryInfo = $categoryClass->get($category,true);
		$cid='';
		$name='';
		if(isset($categoryInfo->category_id) && !empty($categoryInfo->category_id)){
			$cid = "&cid=".$categoryInfo->category_id;
			$name = str_replace(' ','-',strtolower($categoryInfo->category_name));
			$name = "&name=".$name;
		}
		$item_id = '';
		global $Itemid;
		if(isset($Itemid) && !empty($Itemid))
			$item_id = "&Itemid=".$Itemid;


		if($categoryInfo->category_parent_id == '15')
		    $developers .= "<a href='".$url.$cid.$name.$item_id."'>".$categoryInfo->category_name."</a> ";
		elseif($categoryInfo->category_parent_id == '22')
		    $publishers .= "<a href='".$url.$cid.$name.$item_id."'>".$categoryInfo->category_name."</a> ";
	}
        echo "<span class='list-developers'>".JText::_('Developer: ').$developers."</span><br/>";
        echo "<span class='list-publishers'>".JText::_('Publisher: ').$publishers."</span>";
?>

result is

Hi,

You need to change $categoryInfo to $category in the new code. I had forgotten to rename that variable when copy/pasting these lines from the other code.
