PHP Question

How do I call the value from another backed page form and use it on a component in OctoberCms

I'm making a seo plugin and I'm also using the rainlab blog plugin, I have created a tab with fields where I can input the metas that I want to include in the head tag of the page but I don't know how to call the value from the form fields that are in the blog area (rainlab plugin menu tab) while my seo component is at a cms page I have tried to use the {{this.page.variable}}'method but since the input form is at another backend page it doesn't work.

This is how my plugin.php looks like:

<?php namespace Stronganswer\Seo;
use Backend;
use Event;
use System\Classes\PluginBase;
use Cms\Classes\Page;
use Cms\Classes\Theme;
use System\Classes\PluginManager;
use System\Classes\SettingsManager;

class Plugin extends PluginBase
{

/**

*
* @return array
*/
public function pluginDetails()
{
return [
'name' => 'seo',
'description' => 'meta and og tag handler',
'author' => 'stronganswer',
'icon' => 'icon-leaf'
];
}

/**
* Registers any front-end components implemented in this plugin.
*
* @return array
*/
public function registerComponents()
{

return [
'Stronganswer\Seo\Components\Seo' => 'seoHandler',
'Stronganswer\Seo\Components\BlogPost' => 'SeoBlogPost',
'Stronganswer\Seo\Components\StaticPage' => 'SeoStaticPage',
'Stronganswer\Seo\Components\CmsPage' => 'SeoCmsPage',
];
}

public function registerSettings(){
return [
'settings' => [
'label' => 'SEO Settings',
'description' => 'Seo Settings.',
'icon' => 'icon-bar-chart-o',
'class' => 'stronganswer\seo\Models\settings',
'context' => 'mysettings',
'category' => SettingsManager::CATEGORY_MYSETTINGS,
'order' => 1
]
];
}

/**
* Registers any back-end permissions used by this plugin.
*
* @return array
*/
public function registerPermissions()
{

return [
'stronganswer.seo.some_permission' => [
'tab' => 'seo',
'label' => 'Some permission'
],
];
}

/**
* Registers back-end navigation items for this plugin.
*
* @return array
*/
/* public function registerNavigation()
{

return [
'seo' => [
'label' => 'seo',
'url' => Backend::url('stronganswer/seo/controllers'),
'icon' => 'icon-leaf',
'permissions' => ['stronganswer.seo.*'],
'order' => 500,
],
];
}*/

public function boot()
{
Event::listen('backend.form.extendFields', function($widget)
{
if(PluginManager::instance()->hasPlugin('RainLab.Pages') && $widget->model instanceof \RainLab\Pages\Classes\Page)
{ //static pages fields
$widget->addFields([

], 'secondary');
}

if (!$widget->model instanceof \Cms\Classes\Page) return;
//cms page fields
$widget->addFields([

}

}


and this is my component:

The code within the comments are failed trys to get the values from the form. If I go to my database I can see the values that I inputed in the form but I can't call them to my component.

and my deafult.htm :

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

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

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

<meta name="robots" content="{{__SELF__.robot_index}},{{__SELF__.robot_follow}}">

<meta property="og:site_name" content="{{ __SELF__.ogSiteName }}" />

<meta property="og:title" content="{{ __SELF__.ogTitle }}" />

<meta property="og:url" content="{{ __SELF__.ogUrl }}" />

<meta property="og:description" content="{{ __SELF__.ogDescription }}" />

<meta property="og:type" content="{{ __SELF__.ogType }}" />

<meta name="author" content="{{ __SELF__.ogAuthor }}" />

<meta property="og:image" content="{{ __SELF__.ogImage }}" />

<meta property="fb:app_id" content="{{ __SELF__.ogFbAppId }}" />

<meta property="fb:admins" content="{{ __SELF__.ogFbAdmins }}" />

<meta itemprop="name" content="{{ __SELF__.ogGlTitle }}" />

<meta itemprop="description" content="{{ __SELF__.ogGlDescription }}" />

<meta itemprop="image" content="{{ __SELF__.ogGlImage }}" />

<meta itemprop="image" content="{{ __SELF__.ogGlImage }}" />

<meta name="twitter:card" content="{{__SELF__.ogTtCard}}">

<meta name="twitter:site" content="{{__SELF__.ogTtSite}}">

<meta name="twitter:title" content="{{__SELF__.ogTtTitle}}">

<meta name="twitter:description" content="{{__SELF__.ogTtDescription}}">

<meta name="twitter:creator" content="{{__SELF__.ogTtAuthor}}">

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


I also have forms for cms pages and for the rainlab pages plugin(static pages) I get them from another components that I have made and I wanted to point out that both of them are working fine.

Answer

To call the value from the DB I did like this:

Insert this into the component onRun fucntion:

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

Then on the default.htm:

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