How to insert multiple rows from a single query us

Question

I have the following query:

  $query = UserSubject::where('user_id', Auth::id())->select('subject_id')->get();

and as expected I get the following result:

[{"user_id":8,"subject_id":9},{"user_id":8,"subject_id":2}]

Is there a way of copying the above result into another table so that my table looks like this?

ID|user_id|subject_id
1 |8      |9
2 |8      |2

The problem I have is that the $query can expect any number of rows and so im unsure how to iterate through an unknown number of rows.

Answer 1

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

Answer 2

It is really easy to do a bulk insert in Laravel using Eloquent or the query builder.

You can use the following approach.

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data); // Eloquent approach
DB::table('table')->insert($data); // Query Builder approach

In your case you already have the data within the $query variable.
