如何从其他支持的页面表单中调用该值并在OctoberCms

Question

我正在制作一个seo插件，我也在使用rainlab博客插件，我创建了一个带有字段的选项卡，我可以输入我想要包含在页面标题中的元数据但我不知道知道如何调用博客区域（rainlab插件菜单选项卡）中的表单字段中的值，而我的seo组件位于cms页面，我尝试使用{{this.page.variable}}'方法但由于输入表单位于另一个后端页面，因此无效。

这就是我的plugin.php的样子：

<?php namespace Stronganswer\Seo;

        'description' => 'meta and og tag handler',

注释中的代码是失败的trys，用于从表单中获取值。如果我进入我的数据库，我可以看到我在表单中输入的值，但我无法将它们调用到我的组件中。

和我的deafult.htm：

  <meta name="description" content="{{__SELF__.seo_description}}">

  <meta name="keywords" content="{{__SELF__.seo_keywords}}">

  <meta name="twitter:image:src" content="{{__SELF__.ogTtImage}}">

我也有cms页面的表单和rainlab页面插件（静态页面）我从其他组件中获取它们，我想指出它们都工作正常。

Answer 1

要从DB中调用值，我确实这样做了：

将此插入到运行中的组件：

$this->blog_seo_or_smth = DB::table('rainlab_blog_posts')->where('slug','first-blog-post')->first();

然后在default.htm：

<meta name="title" content="{{__SELF__.blog_seo_or_smth.seo_title}}">

Answer 2

我还在努力了解如何在cmsPages和rainlabPages中同时扩展字段，然后在我的html源代码中使用部分打印文件。 所以我创建了这个部分：

M = Locally modified

U = Updated in repository

A = Locally added

D = Locally deleted

I = Ignored

R = Replaced in the repository

– = The contents of the folder have mixed status; display the contents to see individual status

? = Not under source control

我认为最好的解决方案是：创建一个扩展cmsPages和rainLab页面字段的插件，而不是部分打印！ 通过anandpatel查看seoextension的代码可能会有所帮助，但我在编码方面不是很强，所以我们可以互相帮助。

我认为功能是：

<meta charset="utf-8" >
<meta http-equiv="X-UA-Compatible" content="IE=edge" >
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="description" content="{{ this.page.meta_description }}">

<meta name="robots" content=",">
<meta property="og:title" content="October - {{ this.page.title }}" />
<meta property="og:url" content="{{ this.page.url }}" />
<meta property="og:site_name" content="{{ title }}" />
<meta property="og:description" content="{{ this.page.meta_description }}" />
<meta property="fb:app_id" content="xxx" />
<meta property="og:type" content="xxx">
<meta property="og:image" content="{{ this.theme.site_logo_url }}">
<meta name="twitter:card" content="{{ summary }}">
<meta name="twitter:title" content="October- {{ this.page.title }}">
<meta name="twitter:description" content="{{ this.page.meta_description }}">
<meta name="twitter:image" content="{{ this.theme.site_logo_url }}">

也许我们可以将这个项目插入git。

如果您需要表单中的值，请使用Input类

https://octobercms.com/docs/services/request-input

  

您可以使用一些简单的方法访问所有用户输入。使用输入外观时，您无需担心请求的HTTP谓词，因为所有谓词都以相同的方式访问输入。全局input（）辅助函数是Input :: get。

的别名      

检索输入值

$name = Input::get('name');

  

如果输入值不存在，则检索默认值

$name = Input::get('name', 'Sally');

  

确定输入值是否存在

if (Input::has('name')) {
    //
}

但我认为你意味着别的东西，但我不确定，因为实际的问题并不清楚。

在扩展插件时需要考虑很多事情，在这些情况下应该检查：

• 我的字段是否在数据库中创建？
• 我的值是否保存在数据库中？
• 我应该在这些项目上使用关系而不是修改这些项目
• 我可以dd($somevalue)我的组件中的值（dd会杀死任何执行并转储变量。对于分析它们非常有用）
• 我是否有一个单独的管理模型和控制器来管理我的值以进行调试。那些展示了什么？
• 我可以通过查询直接访问这些值吗？
• 是否正确配置/注册了我的组件设置？
• 在设置/事件日志
中跟踪了哪些错误

在开始时调试十月可能会很痛苦，但是一旦掌握了它就很有趣： - ）
