Laravel sync() - Syncing an Array and Passing Additional Pivot Fields

If you've been working with Laravel, chances are you've come across the sync() function. This handy function allows you to synchronize the relationship between two models by updating the pivot table. But what if you need to sync an array and also pass additional pivot fields? 🤔

Let's dive into this common issue and provide you with an easy solution.

Understanding the sync() Function

Before we proceed, let's quickly review what the sync() function does. In Laravel, when you have a many-to-many relationship between two models, you can use the sync() function to sync the related models in the pivot table.

For example, consider a scenario where a User model has many Roles, and vice versa. You can sync the roles for a user using the sync() function like this:

$user->roles()->sync([1, 2, 3]);

This will remove any existing roles not present in the array and add the new roles specified in the array.

Adding Additional Pivot Fields

Now, what if you want to associate other pivot table values with the given IDs? Laravel allows you to do this as well. Let's take a look at the example provided in the question:

$user->roles()->sync([1 => ['expires' => true]]);

In this case, a single pivot row is being added, and the expires field is set to true.

Associating Multiple Pivot Rows

But what if you have more than one row to be synced? How can you associate multiple pivot table records? The answer lies in the structure of the array you pass to the sync() function.

To sync multiple pivot rows, you can simply pass an array of arrays. Each sub-array represents a pivot row and can contain additional pivot fields.

Here's an example to illustrate this:

$user->roles()->sync([
    1 => ['expires' => true, 'active' => true],
    2 => ['expires' => true, 'active' => false],
    3 => ['expires' => false, 'active' => true],
]);

In this example, we are syncing three roles with the user. Each role has its own pivot fields (expires and active) defined.

Conclusion and Call-to-Action

And there you have it! You now know how to sync an array and pass additional pivot fields in Laravel using the sync() function.

Next time you encounter this issue, remember the structure of the array you pass to the sync() function. You can easily associate multiple pivot table records by using an array of arrays.
