The Real Difference Between addAttributeToFilter and addFieldToFilter in Magento 2
Magento developers often run into a common question: what’s the difference between addAttributeToFilter and addFieldToFilter in Magento 2? On the surface, they might seem interchangeable, but the logic behind them tells a different story.
Let’s get straight into it. No vague explanations, just exactly what you need to know.
An Overview
addAttributeToFilter: Works With EAV Data
Magento 2 uses the Entity-Attribute-Value (EAV) model for certain entities like products and customers. This model is flexible but comes with a learning curve. That’s where addAttributeToFilter fits in, it’s made specifically to work with this structure.
In simple terms, use addAttributeToFilter when you’re filtering by attributes that are defined in the Magento admin panel, like SKU, color, size, etc. These are not standard columns in a table but rather values stored in the EAV model, as shown here.
Use case example:
$productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
$productCollection->addAttributeToFilter('sku', 'example_sku');
Here, sku is an EAV attribute. This line fetches products where the SKU is example_sku.
So, when your filter needs to pull values from Magento attributes that were added via the admin, addAttributeToFilter is the right method to use.
addFieldToFilter: Meant for Flat Table Columns
On the flip side, addFieldToFilter is a workhorse when you’re dealing with regular, non-EAV based tables. Think of sales orders, customer addresses, invoices, these follow a flat table structure in the database.
addFieldToFilter interacts directly with database columns, not abstracted attribute values. It’s ideal when your filtering logic revolves around data that’s physically stored in the database tables, such as in Magento Cloud Bitbucket integration scenarios.
Use case example:
$orderCollection = $objectManager->create('Magento\Sales\Model\ResourceModel\Order\Collection');
$orderCollection->addFieldToFilter('status', 'complete');
Here, status is a direct field in the sales order table. No EAV logic involved.
Magento Attribute vs. Field Filtering, Clear Comparison
Data Type
- addAttributeToFilter: Works with EAV attributes
- addFieldToFilter: Targets database table columns
Use Case
- addAttributeToFilter: Ideal for product filtering (e.g., color, size)
- addFieldToFilter: Used for non-EAV collections (e.g., order status)
Admin Panel Link
- addAttributeToFilter: Attributes are managed in the Magento admin panel
- addFieldToFilter: No direct link in the admin panel
So, Which One Should You Use?
Now that you’ve seen how they differ, here’s how to decide:
- Use addAttributeToFilter for products or other EAV-based entities.
- Use addFieldToFilter for orders, invoices, and non-EAV entities.
There’s no “one is better than the other” here, it all depends on the structure of the data you’re working with. And that’s the real difference between addAttributeToFilter and addFieldToFilter in Magento 2.

Conclusion
To recap, the difference between addAttributeToFilter and addFieldToFilter in Magento 2 boils down to how Magento stores the data behind the scenes. One is for EAV attributes managed via the admin, the other for straight-up database columns.
Understanding this difference isn’t just helpful, it’s essential if you’re building efficient, error-free Magento modules or custom features like this.
