添加自定义字段以获取产品页面（仅适用于特定产品ID）

Question

I need to add custom tab on product page, but i want it show it only for some product ids.

Here my code for adding the custom tab on front end.

add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab' );
function woo_new_product_tab( $tabs ) {
    $tabs['desc_tab'] = array(
        'title'     => __( 'Additional Information', 'woocommerce' ),
        'priority'  => 50,
        'callback'  => 'woo_new_product_tab_content'
    );

    return $tabs;
}

and then i should add below function too for displaying the content.

function woo_new_product_tab_content() {
    echo '<p>some text</p>';
}

but now these function work for all product ids. I want to load this two function only for some product id, could someone help me?

I tired to add if(is_product() && get_the_id() == 8) on both functions but $tabs not appear on others product ids page , ( on product id "8" $tabs worked well )

Answer 1

the problem of that code wast about to forget return $tabs

if(is_product()) {
//if(is_product())) {
return $tabs;
}
return $tabs;
}

so the final code could be like this.

function woo_new_product_tab( $tabs ) {
if(condition) {
$tabs['desc_tab'] = array(
    'title'     => __( 'Additional Information', 'woocommerce' ),
    'priority'  => 50,
    'callback'  => 'woo_new_product_tab_content'
);
return $tabs;
}
return $tabs;
}
