我添加了一个函数，该函数将返回允许的html标记数组

if ( ! function_exists( \'allowed_html_tags\' ) ) {
  /**
   * Allowed html tags for wp_kses() function
   *
   * @return array Array of allowed html tags.
   */
  function allowed_html_tags() {
    return array(
      \'a\' => array(
        \'href\' => array(),
        \'title\' => array(),
        \'class\' => array(),
        \'data\' => array(),
        \'rel\'   => array(),
      ),
      \'br\' => array(),
      \'em\' => array(),
      \'ul\' => array(
          \'class\' => array(),
      ),
      \'ol\' => array(
          \'class\' => array(),
      ),
      \'li\' => array(
          \'class\' => array(),
      ),
      \'strong\' => array(),
      \'div\' => array(
        \'class\' => array(),
        \'data\' => array(),
        \'style\' => array(),
      ),
      \'span\' => array(
        \'class\' => array(),
        \'style\' => array(),
      ),
      \'img\' => array(
          \'alt\'    => array(),
          \'class\'  => array(),
          \'height\' => array(),
          \'src\'    => array(),
          \'width\'  => array(),
      ),
      \'select\' => array(
          \'id\'   => array(),
          \'class\' => array(),
          \'name\' => array(),
      ),
      \'option\' => array(
          \'value\' => array(),
          \'selected\' => array(),
      ),
    );
  }
}

但是当我在一个变量中使用html时foreach 回路，我的data 属性被剥离。

$my_var = \'<div class="my-class" data-term="$term_id">$content</div>\';

wp_kses( $my_var, allowed_html_tags() );

这将返回

<div class="my-class">This is my content... no data attribute...</div>

我试图修改我的数组data-* 但那没用。

我希望您不必用完整的数据名修改允许的数组(data-term) 为了让它工作。。。

编辑检查Matt Thomason\'s 关于kses数据更新的回答。

$my_var = \'<div class="my-class" data-term="\' . esc_attr( $term_id ) . \'">\' . wp_kses_post( $content ) . \'</div>\';

add_filter(\'wp_kses_allowed_html\', "kses_filter_allowed_html"));

function kses_filter_allowed_html( $allowed, $context )
{
    if (is_array($context))
    {
        return $allowed;
    }

    if ($context === \'post\')
    {
        $allowed[\'a\'][\'data-*\'] = true;
        $allowed[\'table\'][\'data-*\'] = true; 
        // ... keep on doing these for each HTML entity you want to allow data- attributes on
    }

    return $allowed;
}
