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 Headers 中的元数据但我不知道如何要从博客区域(rainlab插件菜单选项卡)中的表单字段调用值,而我的seo组件位于cms页面,我尝试使用{}'方法但是因为输入表格在另一个后端页面,它不起作用 .
这就是我的plugin.php的样子:

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 .

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 .

要从DB调用值,我这样做:
将其插入到运行中的组件中:
然后在default.htm上:
我也正在努力了解如何在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:
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:
也许我们可以将这个项目插入到git中 .
再见加布里埃尔
如果需要表单中的值,请使用
Input
类https://octobercms.com/docs/services/request-input
但我认为你的意思是别的,但我不确定,因为实际的问题并不清楚 .
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杀死任何执行并转储变量 . 非常有用的分析它们)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 . 这些展示了什么?
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?
设置/事件日志中跟踪了哪些错误
调试十月可能是一个痛苦的开始,但一旦你掌握它很有趣:-)
