我最近安装了bonpress 主题和标题显示不正确。我越想了解字幕在Wordpress中的工作原理，就越怀疑我的安装有问题。

当创建帖子并插入带有标题的图像时，Wordpress会创建以下短代码：

[caption id="attachment_40" align="alignleft" width="1024"]<a href="http://wordpress.local/wp-content/uploads/2012/10/2012-10-30-11.38.36.jpg"><img class="size-large wp-image-40" title="Torn motorcycle cover" src="http://wordpress.local/wp-content/uploads/2012/10/2012-10-30-11.38.36-e1351653272372-1024x984.jpg" alt="" width="1024" height="984" /></a> That\'s what I get for only spending $15 on a motorcycle cover[/caption]

当我阅读几页时，如the first example here 和the sample code here （由bonpress使用），标题似乎应该作为属性传递，例如：

[caption id="attachment_40" align="alignleft" width="1024" caption="That\'s what I get for only spending $15 on a motorcycle cover"]<a href="http://wordpress.local/wp-content/uploads/2012/10/2012-10-30-11.38.36.jpg"><img class="size-large wp-image-40" title="Torn motorcycle cover" src="http://wordpress.local/wp-content/uploads/2012/10/2012-10-30-11.38.36-e1351653272372-1024x984.jpg" alt="" width="1024" height="984" /></a>[/caption]

如果我用caption 作为属性，它可以正确渲染。我的安装中是否有损坏的内容，使其无法以这种方式构建？

Update: 标题短代码由image_add_caption 在/wp admin/includes/media中。php（WP 3.4.2中的第134行）。短代码是根据这段代码正确构造的，因此我想知道为什么我能找到所有关于img_caption_shortcode 筛选器假定标题是属性？

/*
add_shortcode(\'wp_caption\', \'fixed_img_caption_shortcode\');
add_shortcode(\'caption\', \'fixed_img_caption_shortcode\');
function fixed_img_caption_shortcode($attr, $content = null) {
    // Allow plugins/themes to override the default caption template.
    $output = apply_filters(\'img_caption_shortcode\', \'\', $attr, $content);
    if ( $output != \'\' ) return $output;
    extract(shortcode_atts(array(
        \'id\'=> \'\',
        \'align\' => \'alignnone\',
        \'width\' => \'\',
        \'caption\' => \'\'), $attr));
    if ( 1 > (int) $width || empty($caption) )
    return $content;
    if ( $id ) $id = \'id="\' . esc_attr($id) . \'" \';
    return \'<div \' . $id . \'class="wp-caption \' . esc_attr($align)
    . \'">\'
    . do_shortcode( $content ) . \'<p class="wp-caption-text">\'
    . $caption . \'</p></div>\';
}    

*/

if ( ! isset( $attr[\'caption\'] ) ) {
    if ( preg_match( \'#((?:<a [^>]+>\\s*)?<img [^>]+>(?:\\s*</a>)?)(.*)#is\', $content, $matches ) ) {
        $content = $matches[1];
        $attr[\'caption\'] = trim( $matches[2] );
    }
}

add_shortcode(\'wp_caption\', \'img_caption_shortcode\');
add_shortcode(\'caption\', \'img_caption_shortcode\');
