如何過濾循環在創世Studiopress AgentPress列表插件？

Question

我需要幫助，創建一個過濾器，將以下代碼行84上的「查看列表」更改爲「立即預訂」。

我需要幫助爲兒童主題functions.php文件製作自定義過濾器，以便在更新插件時不會保持變回。你可以在這裏看到這個網站：https://webclient.co/running - 循環在運行遊覽的主頁上。

的插件有過濾器「agentpress_featured_listings_widget_loop」，所以這應該這樣做。它進入你的functions.php文件或你的函數插件。

    $loop .= sprintf('<span class="entry-title">' . (get_the_title()) . '</span>'); 

    $loop .= sprintf('<span class="listing-price">%s</span>', genesis_get_custom_field('_listing_price'));

    return $loop; 

} 
add_filter('agentpress_featured_listings_widget_loop', 'agentpress_featured_listings_widget_loop_filter', 10, 1);
