When does Magento consider a cart to be abandoned? Where's that time limit set?

Question

If left to default settings, what circumstances would have to occur for Magento 1.7 to consider a cart abandoned? Where is the code that makes this determination located?

I know that this is probably set somewhere in the quote, but I can't find it for the life of me.

I've done some Googling, but like so many Magento questions I'm left empty handed. Thanks!

Answer 1

As you probably know the setting is located here:

Admin => system => Configuration => Sales => Checkout => Shopping Cart => Quote Lifetime (days)

This will add the setting to the database (core_config_data table) with path:

checkout/cart/delete_quote_after

This path is used in the code on:

app/code/core/Mage/Sales/Model/Observer.php line 54

So when someone is adding something to a cart it will be updated. When a customer logs in and his cart is there it will be updated. When a cart is not updated for the last 30 days. It will be removed.

Extra information:

In case you wonder when this code is used, It is used by the cronjob of magento.

check: App/code/core/Mage/Sales/etc/config.xml line 1732

<crontab>
    <jobs>
        <sales_clean_quotes>
            <schedule>
                <cron_expr>0 0 * * *</cron_expr>
            </schedule>
            <run>
                <model>sales/observer::cleanExpiredQuotes</model>
            </run>
        </sales_clean_quotes>

Hope this helps.

As an oft quoted sick joke, the observer only cleans out completed orders -> $quotes->addFieldToFilter('is_active', 0); and as abandoned carts never get is_active set from 1 to 0, abandoned guest carts have infinite staying power and after a year, can consume considerable database storage space. – Weinstock

I read that that the "Quote Lifetime (days)" only applies to (anonymous) nog-logged-in customers. But a cart from a logged-in user never expires. Have you come across this difference in behavior? – Hasid

@Edison thanks for pointing out. i have removed the links to the old source code. – Lissy

Answer 2

The question was about when a cart becomes abandoned, not when the quote expires. As Magento doesn't have abandoned cart functionality, it's arbitrary. The various extensions to add it let you set it.

Magento does have an abandoned cart "functionality" in the sense that it has carts it considers abandoned, it just doesn't have a mechanism for doing anything with said carts. – Slip

In our e-commerce we've overridden the method cleanExpiredQuotes inside app/code/core/Mage/Sales/Model/Observer.php

Our business rule looks like this:

$quotes = Mage::getModel('sales/quote')->getCollection();     
$quotes->addFieldToFilter('created_at', array('to' => date("Y-m-d", time() - $lifetime)));

$quotes->addFieldToFilter('is_active', 1);
foreach ($this->getExpireQuotesAdditionalFilterFields() as $field => $condition) {
    $quotes->addFieldToFilter($field, $condition);
}
$quotes->walk('delete');
