How to Create Attributes in WooCommerce Programmatically?

Attributes are the labels we use to provide additional details for our products. For example, an “attributes” label for a shirt might include “Size,” “Color,” and “Material.”

In WooCommerce, attributes are created from the Products > Attributes page. Here you can add, edit, and delete attributes as needed.

However, sometimes you may need to create attributes programmatically. This can be done with a few simple lines of code.

Here’s how:

1. First, you’ll need to register the attribute. You can do this with the register_taxonomy function:

function register_my_attribute() {register_taxonomy('pa_my_attribute',   
//The name of the taxonomy. Name should be in slug form 
(must not contain capital letters or spaces). 
'product',//post type name array(  
'hierarchical' => true,  
'label' => 'My Attribute',  //Display name
'query_var' => true,  
'rewrite' => array(  
'slug' => 'my-attribute'    
// This controls the base slug that will display before each term 
//'with_front' => false 
// Don't display the category base before )));}  

2. Create terms for the attribute. Terms are the actual values that will be assigned to products (e.g. “Small,” “Red,” or “Cotton”). You can create terms with the wp_insert_term function:

// First, create the term $term = wp_insert_term(  
'Small', // The term 
'pa_my_attribute', // The taxonomy array('description'=> 'This is a small size',// The description of the term 
'slug' => 'small' // The slug for the term (optional))  ); 

3. Assign terms to products. Once you have registered an attribute and created its terms, you can assign those terms to products. You can do this with the wp_set_object_termsfunction:

// Assign terms to a product by post ID (replace 123 with actual post ID) 
 $product_id = 123;   
 $terms = array( 'small', 'red', );   
 wp_set_object_terms( $product_id, $terms, 'pa_my-attribute');
