woocommerce: add value to a product attribute

问题:

How do I add value to a woocommerce attribute through code? I have created an attribute called 'Dispatch time' (taxonomy: pa_dispatch) and now I want to add value to a particular product's Dispatch attribute.

How to do this programmatically?

回答1:

I found the answer, you need to use wp_set_object_terms to set the terms of object of a taxonomy,

wp_set_object_terms( $object_id, $terms, $taxonomy, $append); 

Where, $append can be true or false, if true, the tag will be appended to existing tag, if false, the tag is replaced.

In my example,

wp_set_object_terms( $object_id, '2 Business Days', 'pa_dispatch' , false); 

Here, the pa_dispatch is the woo-commerce taxonomy.

You cannot add value to an attribute. You need to make the product variable, create a variation, and assign it with the attribute. Now in this variation you can assign a value.

EDIT:

After more clarification on the question, here is an updated solution.

Add the below function to your functions.php. Call it on the appropriate hook and pass the product ID as well as the attribute values.

function se19519561_set_attributes($post_id, $attributes) {      //Type attribute     $product_attributes['type'] = array(         //Make sure the 'name' is same as you have the attribute         'name' => htmlspecialchars(stripslashes('Dispatch Time')),         'value' => $attributes,         'position' => 1,         'is_visible' => 1,         'is_variation' => 1,         'is_taxonomy' => 0     );  //Add as post meta update_post_meta($post_id, '_product_attributes', $product_attributes);  } 

Hope this helps!
