Magento 1: Check if customer has quote

Question

How can I filter customers by the fact if they have a quote in the sales_flat_quote table? I could foreach every customer to check if their email address is located in the sales_flat_quote table, but that doesn't sound like a good way to do it.

Answer 1

You can filter that table with its corresponding collection model:

$quote = Mage::getResourceModel('sales/quote_collection')
         ->addAttributeToFilter('customer_id', $customer->getId())
         ->addAttributeToFilter('is_active', 1)
         ->getFirstItem();

if($quote) {
    //customer has quote
}

You only need the customer ID.
