Question

在页面上多次使用此短代码时，每个短代码都会获得addpad类的输出和内联样式。我该怎么做才能只有具有属性的短代码输出代码？

function block_one_third( $atts, $content = null ) {
   extract(shortcode_atts(array(
      'bg' => '',
      'text' => '',
   ), $atts));
   if (isset($bg) || isset($text)){ $style = ' style="background-color:'. $bg .';color:'. $text .'"';}
   if (isset($bg) || isset($text)) { $padit = ' addpad'; }
   return '<div class="one_third'. $padit .'"'. $style .'>' . do_shortcode($content) . '</div>';
}
add_shortcode('one_third', 'block_one_third');

[one_third]
Block 1 - Should have NO additional class or inline style
[/one_third]
[one_third bg="red"]
Block 2 WITH additional html output
[/one_third]
[one_third_last]
Block 3 - Should have NO additional class or inline style
[/one_third_last]

从技术上讲，isset($bg)将返回true，因为在这些行中，如果未设置，则指定$bg的默认值：

extract(shortcode_atts(array(
  'bg' => '', // $bg default is '' if it wasn't found
  'text' => '', // $text default is '' if it wasn't found
), $atts));

检查它是否等于默认值，而不是检查它是否已设置：

if (strcmp($bg,'') == 0 || strcmp($text,'') == 0 ) {
    // Do Something
}

Wordpress PHP Shortcode如果isset通过页面上的所有短代码
