Adding content after add to cart button on woocommerce single page
提问by dingo_d
I have successfully added a content after short description on single product page with
我在单个产品页面上的简短描述后成功添加了内容
if (!function_exists('my_content')) {
function my_content( $content ) {
$content .= '<div class="custom_content">Custom content!</div>';
return $content;
}
}
add_filter('woocommerce_short_description', 'my_content', 10, 2);
I saw that in short-description.phpthere was apply_filters( 'woocommerce_short_description', $post->post_excerpt )
我看到short-description.php里面有apply_filters( 'woocommerce_short_description', $post->post_excerpt )
so I hooked to that.
所以我迷上了。
In the same way, I'd like to add a content after the add to cart button, so I found do_action( 'woocommerce_before_add_to_cart_button' ), and now I am hooking to woocommerce_before_add_to_cart_button. I'm using
同样，我想在添加到购物车按钮后添加一个内容，所以我找到了do_action( 'woocommerce_before_add_to_cart_button' )，现在我正在挂钩到woocommerce_before_add_to_cart_button. 我正在使用
if (!function_exists('my_content_second')) {
function my_content_second( $content ) {
$content .= '<div class="second_content">Other content here!</div>';
return $content;
}
}
add_action('woocommerce_after_add_to_cart_button', 'my_content_second');
But nothing happens. Can I only hook to hooks inside apply_filters? From what I've understood so far by working with hooks is that you only need a hook name to hook to and that's it. The first one was a filter hook, so I used add_filter, and the second one is action hook so I should use add_action, and all should work. So why doesn't it?
但什么也没有发生。我只能钩在里面的钩子上apply_filters吗？到目前为止，通过使用钩子，我了解到您只需要一个钩子名称即可挂钩，仅此而已。第一个是过滤器钩子，所以我使用了add_filter，第二个是动作钩子，所以我应该使用add_action，一切都应该工作。那为什么不呢？

Here, you need to echo content as it is add_action hook.
在这里，您需要回显内容，因为它是 add_action 钩子。
add_action( 'woocommerce_after_add_to_cart_button', 'add_content_after_addtocart_button_func' );
/*
* Content below "Add to cart" Button.
*/
function add_content_after_addtocart_button_func() {
// Echo content.
echo '<div class="second_content">Other content here!</div>';
}
