getting the value of an extra pivot table column laravel

Solution 1:

When using Many to Many relationships with Eloquent, the resulting model automatically gets a pivot attribute assigned. Through that attribute you're able to access pivot table columns. Although by default there are only the keys in the pivot object. To get your columns in there too, you need to specify them when defining the relationship:

return $this->belongsToMany('Role')->withPivot('foo', 'bar');

Edit

To query the price do this

$model->problems()->where('phone_problem', $problem->id)->first()->pivot->price

Solution 2:

To get data from pivot table:

$price = $model->problems()->findOrFail($problem->id, ['phone_problem'])->pivot->price;

Or if you have many records with different price:

$price = $model->problems()->where('phone_problem', $problem->id)->firstOrFail()->pivot->price;

In addition.

To update data in the pivot you can go NEW WAY:

$model->problems()->sync([$problemId => [ 'price' => $newPrice] ], false); 

Where the 2nd param is set to false meaning that you don't detach all the other related models.

Or, go old way

$model->problems()->updateExistingPivot($problemId, ['price' => $newPrice]);

And remind you:

To delete:

$model->problems()->detach($problemId);

To create new:

$model->problems()->attach($problemId, ['price' => 22]);

It has been tested and proved working in Laravel 5.1 Read more.

Laravel 5.8~

If you want to make a custom pivot model, you can do this:

Account.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Account extends Model
{
    public function users()
    {
        return $this->belongsToMany(User::class)
            ->using(AccountUserPivot::class)
            ->withPivot(
                'status',
                'status_updated_at',
                'status_updated_by',
                'role'
            );
    }
}

AccountUserPivot.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Relations\Pivot;

class AccountUserPivot extends Pivot
{
    protected $appends = [
        'status_updated_by_nice',
    ];

    public function getStatusUpdatedByNiceAttribute()
    {
        $user = User::find($this->status_updated_by);

        if (!$user) return 'n/a';

        return $user->name;
    }
}

In the above example, Account is your normal model, and you have $account->users which has the account_user join table with standard columns account_id and user_id.

If you make a custom pivot model, you can add attributes and mutators onto the relationship's columns. In the above example, once you make the AccountUserPivot model, you instruct your Account model to use it via ->using(AccountUserPivot::class).

Then you can access everything shown in the other answers here, but you can also access the example attribute via $account->user[0]->pivot->status_updated_by_nice (assuming that status_updated_by is a foreign key to an ID in the users table).
