我想为一些产品定制按钮，以取代商店页面上的“添加到购物车”按钮，并将动态重新链接设置到其他页面。因此，我在产品页面上做了一个复选框，如果该复选框已启用，则该产品将可以看到带有不同链接的自定义按钮。以下是复选框的代码：

add_action( \'add_meta_boxes\', \'wdm_add_meta_box\' );
add_action( \'add_meta_boxes\', \'wdm_add_customize_enable_metabox\' );
function wdm_add_customize_enable_metabox() {
    add_meta_box(
        \'Checkbox_metabox\',
        \'Check if you want to enable customization button\',
        \'wdm_enable_callback\',
        \'product\',
        \'normal\',
        \'high\'
    );
}

function wdm_enable_callback( $product ) {
    $custom = get_post_custom( $product -> ID );
    if( isset($custom[ "_wcm_custom_design_checkbox" ][0] ) ) {
        $meta_box_check = $custom[ "_wcm_custom_design_checkbox" ][0];
    }
    else {
        $meta_box_check = FALSE;
    }
    ?>
    <tr>
        <td>Enable design panel at frontend?</td>
        <td><input type="checkbox" name="wcm_enable_checkbox" id="wcm_enable_checkbox" <?php if ( $meta_box_check == true ) { ?> checked="checked"<?php } ?> /></td>
    </tr>
    <tr>
    <?php
}

add_action( \'save_post\', \'wdm_save_meta_check_box_data\', 10,2 );
function wdm_save_meta_check_box_data( $post_id, $product ){
    if ( $product -> post_type == \'product\' ) {
        if ( isset($_POST["wcm_enable_checkbox"] ) && $_POST["wcm_enable_checkbox"] ) {
            update_post_meta( $post_id, \'_wcm_custom_design_checkbox\', $_POST["wcm_enable_checkbox"] );
        }
        else {
            update_post_meta( $post_id, \'_wcm_custom_design_checkbox\', \'\');
        }
    }
}

上述代码工作正常。我将此代码用于主题add_to_cart 循环，这里我唯一的问题是如何定制add_to_cart_url() 有关自定义链接以及如何更改add_to_cart_text() 发短信给我想要的任何人。

以下是我对所做的更改add_to_cart.php:

global $product, $post;
$hasCustomization =  get_post_meta( $post -> ID, \'_wcm_custom_design_checkbox\', true );

if ( $hasCustomization == \'on\' ) {
    echo apply_filters(
        \'woocommerce_loop_add_to_cart_link\',
        sprintf(
            \'<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" class="add_to_cart %s product_type_%s">%s</a>\',
            esc_url( $product -> add_to_cart_url() ),//Here i want my own urls
            esc_attr( $product->id ),
            esc_attr( $product->get_sku() ),
            $product->is_purchasable() ? \'\' : \'\',//own css for custom text to show
            esc_attr( $product->product_type ),
            esc_html( $product->add_to_cart_text() )// Custom Text
        ),
        $product
    );
}

else{
    echo apply_filters(
        \'woocommerce_loop_add_to_cart_link\',
        sprintf(
            \'<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" class="add_to_cart %s product_type_%s">%s</a>\',
            esc_url( $product -> add_to_cart_url() ),
            esc_attr( $product -> id ),
            esc_attr( $product -> get_sku() ),
            $product -> is_purchasable() ? \'add_to_cart_button\' : \'\',
            esc_attr( $product -> product_type ),
            esc_html( $product -> add_to_cart_text() )
        ),
        $product
    );
}
?>

global $product, $post;
$hasCustomization =  get_post_meta( $post -> ID, \'_wcm_custom_design_checkbox\', true );

if ( $hasCustomization == \'on\' ) {
    echo apply_filters(
        \'woocommerce_loop_add_to_cart_link\',
        sprintf(
            \'<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" class="add_to_cart %s product_type_%s">%s</a>\',
            esc_url( $product -> get_permalink() ),
            esc_attr( $product->id ),
            esc_attr( $product->get_sku() ),
            $product->is_purchasable() ? \'\' : \'\',to show
            esc_attr( $product->product_type ),
            esc_html( $product->add_to_cart_text() )// Custom Text
        ),
        $product
    );
}

else{
    echo apply_filters(
        \'woocommerce_loop_add_to_cart_link\',
        sprintf(
            \'<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" class="add_to_cart %s product_type_%s">%s</a>\',
            esc_url( $product -> add_to_cart_url() ),
            esc_attr( $product -> id ),
            esc_attr( $product -> get_sku() ),
            $product -> is_purchasable() ? \'add_to_cart_button\' : \'\',
            esc_attr( $product -> product_type ),
            esc_html( $product -> add_to_cart_text() )
        ),
        $product
    );
}
