php - 在 wordpress 中为 img 标题标签添加标题

Question

我正在尝试将标题添加到 wordpress 中的图像标题标签，以便我使用的灯箱显示标题，因为它显示的只是标题标签。我添加了 $caption 以及从标题短代码中借用的许多其他变体。有什么建议么？

function get_image_tag($id, $alt, $title, $align, $caption, $size='medium') {

    list( $img_src, $width, $height ) = image_downsize($id, $size);
    $hwstring = image_hwstring($width);


    $class = 'align' . esc_attr($align) .' size-' . esc_attr($size) . ' wp-image-' . $id;
    $class = apply_filters('get_image_tag_class', $class, $id, $align, $size);

    $html = '<img src="' . esc_attr($img_src) . '" alt="' . esc_attr($alt) . '" title=" ' . esc_attr($title).' | '. esc_attr($content).'" '.$hwstring.'class="'.$class.'" />';

    $html = apply_filters( 'get_image_tag', $html, $id, $alt, $title, $align, $caption, $size );

    return $html;
}
