wordpress - 在 wordpress 编辑器中更改模板的顺序

Question

当我进入 Wordpress 编辑器时，模板文件按文件名排序。例如：

404.php 页脚.php front-page.php ... .. page.php

我想把这个列表按照模板文件中定义的“模板名称”排序。

这可能吗？

抱歉，theme-editor.php 和 class-wp-theme.php 中没有可用的钩子允许您对文件列表进行排序。

WordPress 使用自定义 scandir 函数来获取文件，然后通过 foreach 循环简单地打印它们。

您必须修改 WordPress 管理核心文件才能更改此设置 - 不建议这样做。

编辑：可能只需要在您的 WordPress 安装中稍作修改就可以更改此顺序。您可以准备一个插件，从管理员中删除默认主题编辑器菜单，并广告另一个链接到您的自定义 theme-editor.php（位于 wp-admin 目录中）这样：

function adjust_the_wp_menu() {
  remove_submenu_page( 'themes.php', 'theme-editor.php' );
  add_submenu_page('themes.php', _x('Editor', 'theme editor'), _x('Editor', 'theme editor'), 'edit_themes', 'my-theme-editor.php');
}

此代码假定您已制作了一个与原始 theme-editor.php 内容完全相同的 theme-editor.php（名为 my-theme-editor.php）的副本。唯一的改变是将 my-theme-editor.php 文件中的所有“theme-editor.php”替换为“my-theme-editor.php”。

当您单击编辑器时，您将始终从管理菜单中输入此文件。整个文件都是您的，您可以尝试以您想要的方式更改顺序。Thant 你必须设法以正确的方式循环你的文件。这并不难，但你也注意到样式表被附加到 php 文件......

作为礼物，我已经为你准备了 my-theme-editor.php 文件；）这里是：

除了将字符串“theme-editor.php”替换为“my-theme-editor.php”外，仅在第 62 行和第 180 行进行了扩展。

但是，小心使用它——我没有正确测试它，但它似乎有效。妙语是，当您有一个插件删除管理菜单并将其替换为您自己的指向 my-theme-editor.php 的链接时，您的 my-theme-editor.php 文件不会被新版本的WordPress。如果它被删除，您可以简单地将其复制回来。
