获取帖子嵌入的图像标题

我正在尝试获取嵌入后图像的标题，然后在灯箱上使用。

这是我的代码：

function my_theme_prefix_content_gallery( $content ) {
    global $post;

    $args = array(
        \'post_type\' => \'attachment\',
        \'post_mime_type\'=>\'image\',
        \'numberposts\' => 1,
        \'post_status\' => null,
        \'post_parent\' => $post->ID,
    );

    $attachments = get_posts( $args );
    if ( $attachments ) {
        foreach ( $attachments as $attachment ) {
           $caption = $attachment->post_excerpt;
        }
    }

    $pattern     = "/<a(.*?)href=(\'|\\")(.*?).(bmp|gif|jpeg|jpg|png)(\'|\\")(.*?)>/i";
    $replacement = \'<a$1href=$2$3.$4$5 rel="lightbox" title="\' . $caption . \'"$6>\';
    $content     = preg_replace( $pattern, $replacement, $content );

    return $content;
}
add_filter( \'the_content\', \'my_theme_prefix_content_gallery\' );

我现在拥有的（上面的代码）是媒体库中其他图像的标题。如何获取我看到的图像的标题？

EDIT

嵌入图像弹出窗口的放大弹出位：

 $(\'a[rel="lightbox"]\').magnificPopup ({
        type: \'image\',
        mainClass: \'mfp-fade\',
        fixedContentPos: false,
        removalDelay: 350,
        gallery: {
            enabled: true
        }
});

因此，使用这段代码，我可以在单击时在放大弹出窗口中打开嵌入后的图像。我所缺少的只是当他们在放大弹出窗口中打开时显示标题的方式。

<?php function wpse221533_add_caption_title_to_content_gallery_image_attachments( $markup, $id, $size, $permalink, $icon, $text ) { //Target only images if ( ! wp_attachment_is_image( $id ) ) : return $markup; endif; //Limit the scope of the new attributes $post_types = array( \'post\', \'page\' ); if ( ! is_singular( $post_types ) ) : return $markup; endif; //Get attachment data $current_attachment_object = get_post( $id ); //Get attachment caption $current_attachment_caption = $current_attachment_object->post_excerpt; //Nothing wrong with regex, but str_replace is cheaper $markup = str_replace( \' href=\', \' rel="lightbox" title="\' . $current_attachment_caption . \'" href=\', $markup ); return $markup; } add_filter( \'wp_get_attachment_link\', \'wpse221533_add_caption_title_to_content_gallery_image_attachments\', 10, 6 ) ; ?>

<?php function wpse221533_add_caption_title_to_content_single_image_attachments( $content ) { //Limit the scope of the new attributes $post_types = array( \'post\', \'page\' ); if ( ! is_singular( $post_types ) ) : return $content; endif; //Parse the content DOM for links $doc = new DOMDocument(); $doc->loadHTML( $content ); $anchors = $doc->getElementsByTagName( \'a\' ); //Parse each link foreach ( $anchors as $anchor ) : //Get the rel attribute $anchor_rel = $anchor->getAttribute( \'rel\' ); //Get the image ID based on the rel attribute $current_attachment_id = substr( strrchr( $anchor_rel, "-" ), 1 ); //Check if the extracted ID is actually a number if ( ! is_numeric( $current_attachment_id ) ) : return $content; endif; //Target only images if ( ! wp_attachment_is_image( $current_attachment_id ) ) : return $content; endif; //Get the attachment object $current_attachment_object = get_post( $current_attachment_id ); //Get the attachment caption $current_attachment_caption = $current_attachment_object->post_excerpt; //Set the rel attribute $anchor->setAttribute( \'rel\', \'lightbox\' ); //Finally set the title attribute based on the attachment caption $anchor->setAttribute( \'title\', $current_attachment_caption ); endforeach; //Save the DOM changes $content = $doc->saveHTML(); return $content; } add_filter( \'the_content\', \'wpse221533_add_caption_title_to_content_single_image_attachments\', 10, 1 ); ?>

如何修改WP_INCLUDE/BLOCKS/LATEST_posts.php

我是WordPress开发的初学者，希望得到一些帮助。我在一个简单的WordPress网站上工作。基本上，用户希望在主页上显示最新的帖子。我使用了最新帖子块，并将其设置为显示整个帖子内容，现在用户不希望帖子标题链接到单个帖子页面（因为帖子的内容显示在主页上）。如何安全地修改模板文件，使其像h2标记一样使用，而不是在主题中使用的href标记。我知道您可以创建子主题并修改wp_content 文件，但我不确定如何处理中的文件wp_include. 我读到一些关于修改functions.php 但我不确定，如果
