WooCommerce-如果单个产品页面上的产品类别声明

Question

Im trying to do an if statement on single product page to echo a link based on product category product category.

I know i can't use is_product_category() outside of category archive pages. So i've tried using has_term But it's just not echoing what i want. Here's the code i'm using so far.

<?php if( has_term( array( 'mac', 'imac', 'macbook', 'imac-pro' ), 'product_cat' ) ) {
    echo '<a href="#">All Mac Accessories</a>';
} ?>

What am i missing here?

It seems the has_term needs a post id in the third parameter. It doesn't automatically take the third parameter as the current post id. You have to manually pass the the current post id. By default, null is passed in the third parameter according to the documentation.

Check it out here, https://developer.wordpress.org/reference/functions/has_term/

I have the tested the following code in the content-single-product.php and it works perfectly.

<?php 
    $terms = ['sagar', 'tamang'];
    if ( has_term( $terms, 'product_cat', get_the_ID() ) ) {
       echo '<h1>Yes</h1>';
    } else {
        echo '<h1>No</h1>';
    }

?>

You can modify your code as following.

<?php
    if( has_term( array( 'mac', 'imac', 'macbook', 'imac-pro' ), 'product_cat', get_the_ID() ) ) {
        echo '<a href="#">All Mac Accessories</a>';
    } 
?>
