How can I join into insert statement? - php

Question

Here is my table structure:
// pages
+----+-----------------------+--------+
| id | path | method |
+----+-----------------------+--------+
| 1 | list_role | get |
| 2 | make_role | post |
| 3 | edit_role/id | get |
| 4 | list_voucher/activate | get |
| 5 | list_voucher/activate | post |
| 6 | expire_voucher/id | get |
+----+-----------------------+--------+
// role_page
+---------+---------+
| role_id | page_id |
+---------+---------+
Now I want to insert multiple rows into role_page table according to this array: (noted that I have $role_id)
$arr = [['list_role', 'get'], ['list_voucher/activate', 'get']]
$role_id = 4; // for example
So the expected output is:
// role_page
+---------+---------+
| role_id | page_id |
+---------+---------+
| 4 | 1 |
| 4 | 4 |
+---------+---------+
How can I do that by a join?
Currently I do that by a loop on $arr like this:
$role_id = 4;
foreach($arr as $row) {
// match the page id
$page_id = pages::where('path', row[0])->where('method', row[1])->first();
// insert
$role_page = new role_page;
$role_page->role_id = $role_id;
$role_page->page_id = $page_id;
}

Answer 1

Try this
Page Model (you may have to customize this relation)
public function roles(){
return $this->belongsToMany(Role::class, 'role_page', 'page_id', 'role_id')
}
Then
$arr = [['list_role', 'get'], ['list_voucher/activate', 'get']]
$role_id = 4; // for example
$query = Page::query();
foreach ($arr as $page){
$query = $query->orWhere(function($query){
$query->where('path', $page[0])->where('method', $page[1]);
}
}
$pages =$query->get();
foreach($pages as $page){
$page->roles()->attach($role_id);
}

Answer 2

$page_id = pages::where('path', row[0])->where('method', row[1])->first();
This returns an object.
$page_id = pages::where('path', row[0])->where('method', row[1])->first()->id;
This will return just the id.
And then in your foreach you can:
role_page::create([
'page_id' => $page_id,
'role_id' => $role_id
]);
You do have to explicitly state in your role_page model that it's not plural if your not refering to it in a relationship way:
protected $table = 'role_page';
