Magento – Link to configurable product with specific values selected

configurable-productmagento2

Similar to this, but with Magento 2

I want to load a configurable product page, with pre-selected attribute value.

My final purpose is to replace the simple product's url in the catalog with the "parent" configurable's url, with the selected attribute values from the simple product.

I have retrieved the "parent" configurable's url for every product, and i have replaced it with the simple product's url in the catalog. I am missing a way to load the configurable's product page, with different selected values each time.

I adapted my answer from this code snippet here...

This method will take a configured product and a simple child product and return the "hash" URL that preselects the variant. The key method doing the work here is getConfigurableAttributesAsArray()

 /**
 * @param \Magento\Catalog\Model\Product $parentProduct
 * @param \Magento\Catalog\Model\Product $simpleProduct
 * @return string Hashed Url
 */
public function getHashUrl($parentProduct, $simpleProduct)
{
    $configType = $parentProduct->getTypeInstance();
    $attributes = $configType->getConfigurableAttributesAsArray($parentProduct);
    $options = [];
    foreach ($attributes as $attribute) {
        $id = $attribute['attribute_id'];
        $value = $simpleProduct->getData($attribute['attribute_code']);
        $options[$id] = $value;
    }
    $options = http_build_query($options);
    return $parentProduct->getProductUrl().($options ? '#' . $options : '');
}

Configurable Product – How to Link with Pre-Selected Values

This is not a full answer but could be a nudge in the right direction.
You can autoselect configurable product options using an url hash.
Take a look for example here:

http://demo.magentocommerce.com/men/new-arrivals/linen-blazer.html#92=22&180=77

If you add #attribute_id=value_id to the URL Magento will select automatically the options you specify.
Now all you need to do is to find a way to append to the URL of the configurable products these values depending on the page you are on.
If you have only the brand as a configurable attribute then it should be easy.
You already know the id of of the brand attribute.
And for the value just create a new attribute for categories, with a custom source model that returns as options all the brands.
Let's call it brand.
Select for each category the brand you want autoselected.
Then in the product list page add something like this:

$urlSuffix = '';
if (Mage::registry('current_category')) {
    $urlSuffix = '#'.'brand attr id here'.'='.Mage::registry('current_category')->getBrand(); //find a way so you don't hard code the brand attribute id.
}

Then replace all occurrences of

<a href="<?php echo $_product->getUrl()?>">...</a>

with

<a href="<?php echo $_product->getUrl().$urlSuffix;?>">...</a>

If you have more attributes that need to be autoselected I think you can do the same as for brand attribute.
