     return '<h2>DOs</h2>'; 
     return '<div>' . $content . '</div>'; 
    } 
    add_shortcode('insert_dos', 'insert_dos_func'); 



// Shortcode for don'ts 
     function insert_donts_func($atts) { 
      extract(shortcode_atts(array(

      ), $atts)); 

      return "<h2>DON'Ts</h2>"; 
      return "<div>" . $content . "</div>"; 
     } 
     add_shortcode('insert_donts', 'insert_donts_func');

你要面临的第一个问题是使用一个单一的函数内部多个返回语句。第一次返回后的任何内容都不会被执行。

第二个问题是你传递内容的方式。您的属性数组中有一个名为content的元素。如果您在该数组上运行提取，它将覆盖短代码回调的参数$content。

function insert_dos_func($atts, $content) { 

    /** 
    * This is going to get attributes and set defaults. 
    * 
    * Example of a shortcode attribute: 
    * [insert_dos my_attribute="testing"] 
    * 
    * In the code below, if my_attribute isn't set on the shortcode 
    * it's going to default to Hello World. Extract will make it 
    * available as $my_attribute instead of $atts['my_attribute']. 
    * 
    * It's here purely as an example based on the code you originally 
    * posted. $my_attribute isn't actually used in the output. 
    */ 
    extract(shortcode_atts(array(
     'my_attribute' => 'Hello World', 
    ), $atts)); 

    // All content is going to be appended to a string. 
    $output = ''; 

    $output .= '<h2>DOs</h2>'; 
    $output .= '<div>' . $content . '</div>'; 

    // Once we've built our output string, we're going to return it. 
    return $output; 
} 
add_shortcode('insert_dos', 'insert_dos_func');
