Refresh Magento Cache Programmatically

Antonio — Sat, 06 Mar 2010 04:16:45 +0000

When writing processes to automate some of Magento’s normally laborious tasks, perhaps for a product-import script, a mass attribute update script, category import, or inventory adjustment, keep in mind that you may have to refresh some kind of cache — especially when working with attributes. If you are encountering quirks or inconsistencies with your data, try these:

Rebuild Catalog Index

Mage::getSingleton('catalog/index')->rebuild();

Rebuild Flat Catalog Product

Mage::getResourceModel('catalog/product_flat_indexer')->rebuild();

Inventory Stock

Mage::getSingleton('cataloginventory/stock_status')->rebuild();

For more cache refreshes, such as:

Catalog Rewrites
Layered Navigation Indices
Product Image
Search Index

Clear Magento Customers, Orders, Searches, and Tags

From the Magento dashboard, there is no intuitive way of deleting/clearing/resetting customer, order, search, or tag data. As developers, we have to test the various functions of our specific Magento setup before presenting it to the client. Before the site can go live, all of the test data has to be removed so it doesn’t interfere with the client’s other business functions such as accounting and inventory.

Fortunately, removing test data is as easy as running SQL queries:

Clear customers:

TRUNCATE TABLE `customer_entity`

Clear orders:

TRUNCATE TABLE `sales_order`

Clear searches:

TRUNCATE TABLE `catalogsearch_query`

Clear tags:

TRUNCATE TABLE `tag`
TRUNCATE TABLE `tag_relation`

You might have expected to meddle with other tables, like all the `sales_order_*` or `customer_entity_*` tables. However, thanks to the database’s various constraints, any related rows are automatically deleted thus preventing orphan data.
