WordPress的 - 添加類Widget的文本

Question

什麼是添加「文本組件」，並在文本輸入數據中的文本輸入將增加類控件像

<aside id="text-2" class="widget widget_text custom_class_here"> 
... 
</aside> 

我的方式方法是取消註冊窗口小部件文字並重新創建。但我認爲會有更好的辦法。如何做到這一點謝謝

Answer 1

在functions.php文件中註冊了側邊欄。例如

register_sidebar(array(
    'name' => __('Main Sidebar', 'twentytwelve'), 
    'id' => 'sidebar-1', 
    'description' => __('Appears on posts and pages except the optional Front Page template, which has its own widgets', 'twentytwelve'), 
    'before_widget' => '<aside id="%1$s" class="widget %2$s">', 
    'after_widget' => '</aside>', 
    'before_title' => '<h3 class="widget-title">', 
    'after_title' => '</h3>', 
)); 

你想要做的是添加自定義類在aside例如

register_sidebar(array(
    'name' => __('Main Sidebar', 'twentytwelve'), 
    'id' => 'sidebar-1', 
    'description' => __('Appears on posts and pages except the optional Front Page template, which has its own widgets', 'twentytwelve'), 
    'before_widget' => '<aside id="%1$s" class="widget %2$s my_custom_class_here">', 
    'after_widget' => '</aside>', 
    'before_title' => '<h3 class="widget-title">', 
    'after_title' => '</h3>', 
));

可以過濾整個文本並做字符串替換或補充具有：

add_filter('widget_text', 'widget_so_25825107', 10, 2); 

function widget_so_25825107($text, $instance) { 
    $new_text = "manipulate $text here"; 
    return $new_text 
}
