编辑wordpress自定义头php文件

我正在为wordpress网站使用一个开源主题。虽然网站的大部分内容都完成了，但我在为网站添加第二个标语区域时遇到了麻烦

此外，我正在尝试修改customer_header.php，使首页展示也出现在所有页面上

当前，主页是显示标题showcase的唯一页面，只有两行文本。以下是php：

对于第一部分：我不打算为您编写所有代码，但您基本上可以在该文件中找到所有您找到
标题\u标语\u标题
，
标题\u标语\u文本
，以及
标题\u按钮\u文本
，并明智地复制它们

对于第二部分：您需要在问题中链接到的文件中破解此代码：

/**
 * Is showcase area visible on current page
 *
 * @return boolean
 */
public function is_showcase() {

if ( null !== $this->is_showcase ) {
    return $this->is_showcase;
}
$this->is_showcase = ( is_front_page() && ! is_paged() ) ? true : false;
return $this->is_showcase;
}

很可能你会想要改变

$this->is_showcase = ( is_front_page() && ! is_paged() ) ? true : false;

到

或者其他一些模板标记组合，为您希望显示的页面生成true，为其他页面生成false。
首先，坏消息是：customer_header.php是核心WordPress安装的一部分，开发人员永远不应该修改它。好消息是，几乎可以肯定有另一种方法可以完成你想做的事情。如果你能提供一个链接到你正在使用的主题，也许还有这个网站（如果它是活的），那会有帮助的。啊，好的。不过，我很高兴听到还有其他选择。非常感谢。现场站点是主题站点吗？为了清晰起见，您希望首页上的（可爱的）图像也显示在站点的其他页面上？我希望该首页上的图像、文本和按钮显示在所有页面上。我还想在按钮前添加第三行文字。非常有用。。。事实证明，您链接的文件是主题的一部分，而不是（正如我所想的）核心的一部分（核心中有一个custom-header.php，但它不是（正如您可能已经知道的那样）。因此，我做了更改，不幸的是，它没有工作。我是否必须更改头图像块**@return void*/public函数Open_image_wrap（）{$subpage=''；如果（！$this->is_showcase（））{$subpage='is subpage'；}echo'；}部分的/***Open HTML包装？那么，什么不起作用？它没有出现在其他页面上吗？一种故障排除方法是将其设置为“true”：
$this->is\u showcase=true
更改都无效。它仍然没有显示在其他页面上，第三行文本仍然不可用（让我试试布尔值。即使$this->is\u showcase=true也不允许任何更改发生。嗯。我没有时间为自己搭建一个测试平台来尝试这一点，但这确实让我感到惊讶。自上次发布以来，你有什么进展吗？
$this->is_showcase = is_page();
