只是一个建议。

对不想显示的标题使用特定标题或字符。例如* 或# 或idontwanttoshowthistitle

然后在主题中，检查if title != * or # or idontwanttoshowthistitle 将其用作标题。

我最近还需要在一个网站上这样做。

如果您将标题字段保留为空，则WordPress会在保存期间将空标题替换为附件的名称。这是通过向过滤器添加函数来实现的attachment_fields_to_save. 如果我们取消挂钩，则可以使用空标题保存附件：

// Remove WordPress built in filter that filles post name with attachment filename if title is empty on save
// We use prio 5 on our filter because we need to call our function before wordpress calls its own
add_filter( \'attachment_fields_to_save\', \'unhook_attachment_fields_to_save\', 5, 2 );

function unhook_attachment_fields_to_save( $post, $attachment ) {

    // "image_attachment_fields_to_save" is the name of the function
    // that wordpress did add
    remove_filter( \'attachment_fields_to_save\', \'image_attachment_fields_to_save\', 10 );

    return $post;

}
