来自PHTML的Magento SQL查询

Question

I wanted to know how to run sql queries in magento via the phtml files. The query itself is quite complicated and will require joins. Any ideas?

For you information:

I have products which have 3 custom attributes( Towns, Regions, Cities). Now what I am trying to achieve is a list of towns from AZ in an alphabet order. When clicked on this town, it filters the product associated with the town.

Hope it makes sense.

Any help is much appreciated.

The phtml file is technically nothing else than a usual php file, so you can use all models, ressources and so on. So you could just go with:

$resource = Mage::getSingleton('core/resource'); 
$readConnection = $resource->getConnection('core_read'); 
$query = 'SELECT * FROM ' . $resource->getTableName('catalog/product');
$results = $readConnection->fetchAll($query);

BUT the phtml file is a view, so you should not work directly on database there. Instead try to create a model, use that in the block and then call the prepared data from the block object.
