向WooCommerce单个产品页面添加多个选项卡

我试图添加三个自定义选项卡到WooCommerce。我有下面的代码，其中两个显示，但由于某种原因，属性描述选项卡没有显示在页面上。不仅数量定价选项卡没有显示其描述。我试图将代码的不同部分移动到不同的位置，我检查了错误或缺失部分的代码。这是我能找到的最接近的了。

我的过程基本上是删除现有的我不想要的选项卡，然后按我想要它们出现的顺序添加新选项卡。

下面是我使用的代码:

// WooCommerce Tabs

// REMOVE EXISTING TABS
add_filter( 'woocommerce_product_tabs', 'woo_remove_product_tabs', 98 );

function woo_remove_product_tabs( $tabs ) {
    unset( $tabs['description'] );          // Remove the description tab
    // unset( $tabs['reviews'] );           // Remove the reviews tab
    unset( $tabs['additional_information'] );   // Remove the additional information tab
    return $tabs;
}


// ADD ATTRIBUTE DESCRIPTION TAB
add_filter( 'woocommerce_product_tabs', 'woo_attrib_desc_tab' );
function woo_attrib_desc_tab( $tabs ) {
    // Adds the Attribute Description tab
    $tabs['attrib_desc_tab'] = array(
        'title'     => __( 'Desc', 'woocommerce' ),
        'priority'  => 100,
        'callback'  => 'woo_attrib_desc_tab_content'
    );
    return $tabs;
}

// ADD QUANTITY PRICING TAB
add_filter( 'woocommerce_product_tabs', 'woo_qty_pricing_tab' );
function woo_qty_pricing_tab( $tabs ) {
    // Adds the qty pricing  tab
    $tabs['qty_pricing_tab'] = array(
        'title'     => __( 'Quantity Pricing', 'woocommerce' ),
        'priority'  => 110,
        'callback'  => 'woo_qty_pricing_tab_content'
    );
    return $tabs;
}
// ADD OTHER PRODUCTS TAB
add_filter( 'woocommerce_product_tabs', 'woo_other_products_tab' );
function woo_other_products_tab( $tabs ) {
    // Adds the other products tab
    $tabs['other_products_tab'] = array(
        'title'     => __( 'Other Products', 'woocommerce' ),
        'priority'  => 120,
        'callback'  => 'woo_other_products_tab_content'
    );
    return $tabs;
}
// ADD CUSTOM TAB DESCRIPTIONS
function woo_attrib_desc_tab_content() {
    // The attribute description tab content
    echo '<h2>Description</h2>';
    echo '<p>Custom description tab.</p>';
}
function woo_qty_pricing_tab_content() {
    // The qty pricing tab content
    echo '<h2>Quantity Pricing</h2>';
    echo '<p>Here''s your quantity pricing tab.</p>';   
}
function woo_other_products_tab_content() {
    // The other products tab content
    echo '<h2>Other Products</h2>';
    echo '<p>Here''s your other products tab.</p>';
}

编辑每个回复从LoicTheAztec下面，这是我的整个函数。php文件。我在底部有和没有?>的情况下尝试了它:

<?php
add_theme_support( 'builder-3.0' );
add_theme_support( 'builder-responsive' );

function register_my_fonts() {
    wp_register_style('googleFonts-OpenSans', '//fonts.googleapis.com/css?family=Open+Sans:400,300,700');
    wp_enqueue_style( 'googleFonts-OpenSans');
}

add_action('wp_enqueue_scripts', 'register_my_fonts');


function sc_replacecolon( $content ){ return str_replace( '[sc:', '[sc name=', $content ); }
add_filter( 'the_content', 'sc_replacecolon', 5 );

/* WOOCOMMERCE */
add_filter( 'woocommerce_product_tabs', 'woo_custom_product_tabs', 100, 1 );

    unset( $tabs['description'] );              // Remove the description tab
    // unset( $tabs['reviews'] );               // Remove the reviews tab
    unset( $tabs['additional_information'] );   // Remove the additional information tab

    // 2 Adding new tabs
    //Attribute Description tab
    $tabs['attrib_desc_tab'] = array(
        'title'     => __( 'Desc', 'woocommerce' ),
        'priority'  => 100,
        'callback'  => 'woo_attrib_desc_tab_content'
