希望创建一个自定义字段来更改博客存档页上显示的标题，而不影响实际帖子的标题。（这样做的目的是在查看所有帖子时使用较短的标题）

我在博客布局中发现了以下代码行。php。

<div class="fusion-post-content post-content">
                    <?php // Render the post title. ?>
                    <?php echo wp_kses_post( avada_render_post_title( get_the_ID() ) ); ?>

                    <?php // Render post meta for grid and timeline layouts. ?>
                    <?php if ( \'grid\' === $blog_layout || \'timeline\' === $blog_layout ) : ?>
                        <?php echo wp_kses_post( avada_render_post_metadata( \'grid_timeline\' ) ); ?>

                        <?php if ( ( Avada()->settings->get( \'post_meta\' ) && ( Avada()->settings->get( \'post_meta_author\' ) || Avada()->settings->get( \'post_meta_date\' ) || Avada()->settings->get( \'post_meta_cats\' ) || Avada()->settings->get( \'post_meta_tags\' ) || Avada()->settings->get( \'post_meta_comments\' ) || Avada()->settings->get( \'post_meta_read\' ) ) ) && 0 < Avada()->settings->get( \'excerpt_length_blog\' ) ) : ?>
                            <div class="fusion-content-sep"></div>
                        <?php endif; ?>

                    <?php elseif ( \'large-alternate\' === $blog_layout || \'medium-alternate\' === $blog_layout ) : ?>
                        <?php // Render post meta for alternate layouts. ?>
                        <?php echo wp_kses_post( avada_render_post_metadata( \'alternate\' ) ); ?>
                    <?php endif; ?>

                    <div class="fusion-post-content-container">
                        <?php
                        /**
                         * The avada_blog_post_content hook.
                         *
                         * @hooked avada_render_blog_post_content - 10 (outputs the post content wrapped with a container).
                         */
                        do_action( \'avada_blog_post_content\' );
                        ?>
                    </div>
                </div>

编辑：还找到了实际功能：

function avada_render_post_title( $post_id = \'\', $linked = true, $custom_title = \'\', $custom_size = \'2\', $custom_link = \'\' ) {

        $entry_title_class = \'\';

        // Add the entry title class if rich snippets are enabled.
        if ( Avada()->settings->get( \'disable_date_rich_snippet_pages\' ) ) {
            $entry_title_class = \' class="entry-title fusion-post-title"\';
        } else {
            $entry_title_class = \' class="fusion-post-title"\';
        }

        // If we have a custom title, use it otherwise get post title.
        $title = ( $custom_title ) ? $custom_title : get_the_title( $post_id );
        $permalink = ( $custom_link ) ? $custom_link : get_permalink( $post_id );

        // If the post title should be linked at the markup.
        if ( $linked ) {
            $link_target = \'\';
            if ( \'yes\' == fusion_get_page_option( \'link_icon_target\', $post_id ) || \'yes\' == fusion_get_page_option( \'post_links_target\', $post_id ) ) {
                $link_target = \' target="_blank" rel="noopener noreferrer"\';
            }
            $title = \'<a href="\' . $permalink . \'"\' . $link_target . \'>\' . $title . \'</a>\';
        }

        // Return the HTML markup of the post title.
        return \'<h\' . $custom_size . $entry_title_class . \'>\' . $title . \'</h\' . $custom_size . \'>\';

    }

我的第一个想法是，更改get\\u the\\u ID（）参数应该可以做到这一点，但在添加伪文本之后，它似乎没有改变任何东西。

这是应该找的地方吗？

编辑：

非常了解挂钩，但下面是我使用mikesar提供的代码失败的尝试：

add_filter( \'avada_render_post_title\', \'short_title_replace\' );
function short_title_replace(){

  $customTitle = get_post_meta( get_the_ID(), \'short-title\', true );

  if ( ! empty( $customTitle ) ) {
    echo $customTitle;
  } else {
    echo wp_kses_post( avada_render_post_title( get_the_ID() ) );
  }
}

我已经创建了自定义字段，但不确定如何连接到avada_render_post_title函数。

$customTitle = get_post_meta( get_the_ID(), \'CustomFieldSlug\', true );

if ( ! empty( $customTitle ) ) {
    echo $customTitle;
} else {
    echo wp_kses_post( avada_render_post_title( get_the_ID() ) );
}

function avada_render_post_title( $post_id = \'\', $linked = true, $custom_title ....

<?php // Render the post title. ?>
<?php echo wp_kses_post( avada_render_post_title( get_the_ID() ) ); ?>

<?php // Render the post title. ?>
<?php
    $customTitle = get_post_meta( get_the_ID(), \'short-title\', true );
    if ( ! empty( $customTitle ) ) {
      echo wp_kses_post( avada_render_post_title( get_the_ID(), true, $customeTitle ) );
    } else {
      echo wp_kses_post( avada_render_post_title( get_the_ID() ) );
    }
?>
