I have hasMany relationship in my User model;

 /**

 * Get the posts for the users.

 */

public function posts()

{

    return $this->hasMany(Posts::class); //foreign key assigned by user_id

}

I need to get a foreign id in Eloquent data

Controller;

use App\Models\User;



$posts = User::find(1)->posts;



foreach ($posts as $post) {

    //

}

//for example

$foreign_key = $posts->foreign_key;

echo "all posts collection assigned foreign key is; ".$foreign_key;

Expected output;

1

How can I get the foreign key?

My Answer:
You can access the foreign key value from the eloquent collection by using the relationship method. In your case, you can access the foreign key value like this:

php
$posts = User::find(1)->posts;

foreach ($posts as $post) {
$foreign_key = $post->user_id; // Assuming user_id is the foreign key column
echo "Foreign key for post: " . $foreign_key;
}


This code will loop through each post in the collection and retrieve the foreign key value from the post object. In this example, I assumed that the foreign key column in the Posts table is named `user_id`. You can replace `user_id` with the actual foreign key column name in your database.
