Multiple Select - Render as url and search

Question

I'm building a bookshop with Magento. I've some multiple select custom attributes for Authors and Translators.

I'd like to render their values as a link to the advanced search to list all products for that Author / Translator.

First Problem: The advanced search does not accept the string /catalogsearch/advanced/result/?author="Name"
Second Problem: Can I render every item as a Link? for eg. something like this

< a href = "/catalogsearch/advanced/result/?author= < ? php echo $_product->getAttributeText('author') ?>"> < ? php echo $_product->getAttributeText('author') ?>

Hi domfitty, what have you tried and what doesn't work as expected? What you want to achieve sounds reasonable and shouldn't be any problem? — Fabian Blechschmidt

First problem is solved :) For single select attributes I'm able to get it as a link using this code <a href="/catalogsearch/advanced/result/?author=<?php echo $_product->getData('author') ?>"><?php echo $_product->getAttributeText('author') ?></a> I'm not able to parse it if I select 2 or more options because I get an array. Any ideas? — domfitty

If I understand you correctly, your problem is now with multiple select attributes. If you execute an advanced search and look at the resulting URL, you will see it looks like:

[YOUR_BASE_URL]/catalogsearch/advanced/result/?author[]=1&author[]=2&other_attribute[]=45

Actually, this is how you transfer multiple input values with the same name. The name is then not name="author", but name="author[]". Also, make sure you don't use getAttributeText() for the URL part - it expects the option_id, so getData('author') or the magic getter getAuthor() is correct.

Your final link would be like:

<a href="<?php echo Mage::getBaseUrl() ?>catalogsearch/advanced/result/?author[]=<?php echo $_product->getAuthor() ?>"><?php echo $_product->getAttributeText('author') ?></a>

Now to the problem if a product has more than one author. As Fabian suggested, you can use is_array and foreach.

<?php $_authors = $_product->getAuthor(); if( !is_array($_authors) ) { $_authors = explode(',', $_authors); } $_authorTexts = $_product->getAttributeText('author'); if( !is_array($_authorTexts) ) { $_authorTexts = array($_authorTexts); } foreach($_authors as $i => $_author) { ?><a href="<?php echo Mage::getBaseUrl() ?>catalogsearch/advanced/result/?author[]=<?php echo $_author ?>"><?php echo $_authorTexts[$i] ?></a><?php }

You are quite right! I'm trying to use multiple select attributes in product detail and link them INDIVIDUALLY to advanced search page. For example: Book1 with Author1, Author2 --> Link1 to advanced search of Author1 AND Link2 to advanced search of Author2 — domfitty

Because I'd like to have one <a tag for each author and not a unique tag for ALL authors. — domfitty

Hm, sorry, but this is not helpful... what does not work? Is there an error? Is there any output? Could you maybe post the output of var_dump($_authors) and var_dump($_authorTexts) right after their definition? — simonthesorcerer
