我有一个使用自定义短代码的现有站点。当我尝试将它们转换为新主题时&；dev站点，它给了我一个错误。快捷码是关于选项卡式内容的。您可以在此处看到错误：https://dev.brothermartin.com/extracurriculars/academic-games/ 就是这样：

注意：未定义变量：tab3\\u button in/home/brothermartin18/public\\u html/blog/wp content/themes/Brother\\u Martin\\u 2018/lib/admin/shortcodes/shortcodes。php第60行

注意：未定义变量：tab4\\u button in/home/brothermartin18/public\\u html/blog/wp content/themes/Brother\\u Martin\\u 2018/lib/admin/shortcodes/shortcodes。php第60行

注意：未定义变量：tab5\\u button in/home/brothermartin18/public\\u html/blog/wp content/themes/Brother\\u Martin\\u 2018/lib/admin/shortcodes/shortcodes。php第60行

这是与短代码相关的代码：

function mbiz_tabbed_box( $atts, $content = null ) {
 extract( shortcode_atts( array(
  \'tab1\' => \'\',
  \'tab2\' => \'\',
  \'tab3\' => \'\',
  \'tab4\' => \'\',
  \'tab5\' => \'\',
  ), $atts ) );

if ($tab1) $tab1_button = \'<li><a href="#" title="tab1">\' . esc_attr($tab1) . \'</a></li>\';
if ($tab2) $tab2_button = \'<li><a href="#" title="tab2">\' . esc_attr($tab2) . \'</a></li>\';
if ($tab3) $tab3_button = \'<li><a href="#" title="tab3">\' . esc_attr($tab3) . \'</a></li>\';
if ($tab4) $tab4_button = \'<li><a href="#" title="tab4">\' . esc_attr($tab4) . \'</a></li>\';
if ($tab5) $tab5_button = \'<li><a href="#" title="tab5">\' . esc_attr($tab5) . \'</a></li>\';

return \'<div class="tabs-style1"><div class="tabs-navigation"><ul class="tabs-nav">\'
        . $tab1_button . $tab2_button . $tab3_button . $tab4_button . $tab5_button .
        \'</ul></div><div class="tabs-content">\' . do_shortcode($content) . \'</div></div>\';
}
add_shortcode(\'tabbed_box\', \'mbiz_tabbed_box\');

有人对此有任何简单的修复方法吗？仅当未使用5个选项卡时才会发生。我没有创建这些，所以很难排除故障。

function mbiz_tabbed_box( $atts, $content = null ) {
 extract( shortcode_atts( array(
  \'tab1\' => \'\',
  \'tab2\' => \'\',
  \'tab3\' => \'\',
  \'tab4\' => \'\',
  \'tab5\' => \'\',
  ), $atts ) );

$tab1_button = $tab2_button = $tab3_button = $tab4_button = $tab5_button = \'\';

if ($tab1) $tab1_button = \'<li><a href="#" title="tab1">\' . esc_attr($tab1) . \'</a></li>\';
if ($tab2) $tab2_button = \'<li><a href="#" title="tab2">\' . esc_attr($tab2) . \'</a></li>\';
if ($tab3) $tab3_button = \'<li><a href="#" title="tab3">\' . esc_attr($tab3) . \'</a></li>\';
if ($tab4) $tab4_button = \'<li><a href="#" title="tab4">\' . esc_attr($tab4) . \'</a></li>\';
if ($tab5) $tab5_button = \'<li><a href="#" title="tab5">\' . esc_attr($tab5) . \'</a></li>\';

return \'<div class="tabs-style1"><div class="tabs-navigation"><ul class="tabs-nav">\'
        . $tab1_button . $tab2_button . $tab3_button . $tab4_button . $tab5_button .
        \'</ul></div><div class="tabs-content">\' . do_shortcode($content) . \'</div></div>\';
}
add_shortcode(\'tabbed_box\', \'mbiz_tabbed_box\');

$out = \'<div class="tabs-style1"><div class="tabs-navigation"><ul class="tabs-nav">\';
    if ($tab1) $out .= \'<li>whatever</li>\';
    if ($tab2) $out .= \'<li>whatever</li>\';
    if ($tab3) $out .= \'<li>whatever</li>\';
    if ($tab4) $out .= \'<li>whatever</li>\';
    if ($tab5) $out .= \'<li>whatever</li>\';
$out .= \'</ul></div><div class="tabs-content">\' . do_shortcode($content) . \'</div></div>\';

return $out;
