{Name (First):7.3} requested the  following code from my WordPress AI Code Generator.

The following code checks each item in the shopping cart and changes it's tax class.
Modify the code so that it only changes the tax class if the item's category is "solar".

this is the existing code:
foreach( $cart->get_cart() as $cart_item ){
if( $choice === $field_value ) {
$cart_item['data']->set_tax_class($tax_class);
}
}

The robot generated the following code:

To modify this code, we need to check if each item belongs to the 'solar' category. The new code will look something like this:

“`php
foreach( $cart->get_cart() as $cart_item ){
$product_id = $cart_item['product_id'];
$terms = wp_get_post_terms( $product_id, 'product_cat' );
foreach ( $terms as $term ) {
$category = $term->name;
if ( $category === 'solar' && $choice === $field_value ) {
$cart_item['data']->set_tax_class($tax_class);
}
}
}
“`

In this new code, we added some lines to get the categories of each item using `wp_get_post_terms()` function which returns an array of terms. Then, we iterate over each term, checking if its name is 'solar'. If it matches and the `$choice` is equal to `$field_value`, we change the tax class.

Now below is the same code with "nm_" prefixed to all functions:

“`php
foreach( $cart->get_cart() as $cart_item ){
$product_id = $cart_item['product_id'];
$nm_terms = wp_get_post_terms( $product_id, 'product_cat' );
foreach ( $nm_terms as $term ) {
$nm_category = $term->name;
if ( $nm_category === 'solar' && $choice === $field_value ) {
$cart_item['data']->set_tax_class($tax_class);
}
}
}
“`

Please note that: We don't need to prefix WordPress's standard functions like `wp_get_post_terms()`, since it cannot be edited or purposed for other things. We should only prefix our own custom functions to avoid conflicts with WordPress or plugin updates that may have functions with the same name.
