Laravel Eloquent Join 2 Tables with Different Name - php

Question

I want to join 2 tables, t_admin and t_article using eloquent laravel. So this is table t_admin:
id_adm| name | email
-------------------------
4 | Arya | arya#mail.com
7 | Andrea | andrea#mail.com
12 | Adibah | adibah#mail.com
table t_article:
id_article | id_admin | title
--------------------------------
1 | 4 | AAA
2 | 12 | BBB
3 | 7 | CCC
based on that tables, t_admin.id_adm = t_article.id_admin.
This is my model
Admin.php
class Admin extends Model
{
protected $fillable = [
'id_adm','name','email',
];
protected $table = 't_admin';
}
Article.php
class Article extends Model
{
protected $fillable = [
'id_article','id_admin','title',
];
protected $table = 't_article';
}

Answer 1

Create a relationship in your Admin Model:
Note: I am assuming that an Admin can have many article.
public function articles(){
return $this->hasMany('App\Article', 'id_admin');
}
Then, whenever you want to get all articles that belong to an Admin, do this:
$adminArticles = Admin::find($adminId)->articles
In a scenario where an Admin can only have one article, do this instead:
public function article(){
return $this->hasOne('App\Article', 'id_admin');
}
Then, whenever you want to get the article that belongs to an Admin, do this:
$adminArticle = Admin::find($adminId)->article
Read here for more information.
You could also use Laravel's Query Builder to write join queries yourself.
In your case, you would do this:
$adminArticles = DB::table('t_admin')
->join('t_article', 't_admin.id_adm', '=', 't_article.id_admin')
->select('t_admin.*', 't_article.title')
->get();

Answer 2

Add the relationship to the models assuming its one to many
class Admin extends Model
{
protected $fillable = [
'id_adm','name','email',
];
protected $table = 't_admin';
/**
* Get the articles for admin.
*/
public function articles()
{
return $this->hasMany('App\Article');
}
}
class Article extends Model
{
protected $fillable = [
'id_article','id_admin','title',
];
protected $table = 't_article';
/**
* Get the user for the article post.
*/
public function user()
{
return $this->belongsTo('App\Admin');
}
}
You can retrieve them by
$articles = App\Admin::find(1)->articles;
foreach ($articles as $article) {
//
}
