To sync an object with many items in Laravel, you can use the sync
method provided by Eloquent relationships. The sync
method allows you to synchronize the items of a relationship to match the given array of IDs.
Here is an example of how you can use the sync
method to sync an object with many items:
1 2 3 4 5 6 7 |
class Post extends Model { public function tags() { return $this->belongsToMany(Tag::class); } } |
1 2 3 4 5 |
$post = Post::find(1); $tagIds = [1, 2, 3]; $post->tags()->sync($tagIds); |
In this example, we first retrieve the post object with ID 1. Then, we define an array of tag IDs that we want to sync with the post. Finally, we call the sync
method on the tags
relationship of the post object and pass in the array of tag IDs. Laravel will automatically update the relationship to match the given tag IDs.
You can also use the sync
method with additional data by passing an associative array to the method:
1 2 3 4 5 |
$post->tags()->sync([ 1 => ['created_at' => '2022-01-01'], 2 => ['created_at' => '2022-01-02'], 3 => ['created_at' => '2022-01-03'], ]); |
In this example, we are passing an associative array where the key is the tag ID and the value is an array of additional data to be updated in the pivot table for that tag.
