I'm new to Laravel and an amateur at best with PHP, but trying to learn. This is my first question as I've usually been able to find an answer searching.

This is probably something simple I'm overlooking. I am submitting a form that can have up to 2 rows from a view to a controller. I am creating an array from the data like so in my controller: 

    foreach($candidates_member_id as $key => $value)
    {
        $arrData[] = array( 
            'member_user_id'        => $member_user_id[$key],
            'candidates_member_id'  => $candidates_member_id[$key], 
            'candidates_district'   => $candidates_district[$key], 
            'candidate_name'        => $candidate_name[$key], 
            'created_at'            => $created_at[$key],
            'updated_at'            => $updated_at[$key]                        
        );
    }

If I print_r($arrData) on the associated view, I get results as such: 

Array
(
    [0] => Array
        (
            [member_user_id] => 1
            [candidates_member_id] => 12345
            [candidates_district] => 6
            [candidate_name] => Doe, John
            [created_at] => 2016-09-03 15:07:14
            [updated_at] => 2016-09-03 15:07:14
        )

    [1] => Array
        (
            [member_user_id] => 1
            [candidates_member_id] => 54321
            [candidates_district] => 6
            [candidate_name] => Doe, Jane
            [created_at] => 2016-09-03 15:07:15
            [updated_at] => 2016-09-03 15:07:15
        ) 
)

However, when I add DB insert into the above foreach loop:

DB::table('primary_votes')->insert(
            ['member_user_id' => $member_user_id,
             'candidates_member_id' => $candidates_member_id,
             'candidates_district' => $candidates_district,
             'created_at' => $created_at,
             'updated_at' => $updated_at]
        );

I get the following error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: insert into primary_votes (0, 1) values (1, 1), (12345, 54321), (6, 6), (2016-09-03 15:07:14, 2016-09-03 15:07:15), (2016-09-03 15:07:14, 2016-09-03 15:07:15)) in Connection.php line 761 at Connection->runQueryCallback('insert into primary_votes (0, 1) values (?, ?), (?, ?), (?, ?), (?, ?), (?, ?)', array('1', '1', '12345', '54321', '6', '6', '2016-09-03 15:07:14', '2016-09-03 15:07:15', '2016-09-03 15:07:14', '2016-09-03 15:07:15'), object(Closure)) in Connection.php line 717 at Connection->run('insert into primary_votes (0, 1) values (?, ?), (?, ?), (?, ?), (?, ?), (?, ?)', array('1', '1', '12345', '54321', '6', '6', '2016-09-03 15:07:14', '2016-09-03 15:07:15', '2016-09-03 15:07:14', '2016-09-03 15:07:15'), object(Closure)) in Connection.php line 481 at Connection->statement('insert into primary_votes (0, 1) values (?, ?), (?, ?), (?, ?), (?, ?), (?, ?)', array('1', '1', '12345', '54321', '6', '6', '2016-09-03 15:07:14', '2016-09-03 15:07:15', '2016-09-03 15:07:14', '2016-09-03 15:07:15')) in Connection.php line 435 at Connection->insert('insert into primary_votes (0, 1) values (?, ?), (?, ?), (?, ?), (?, ?), (?, ?)', array('1', '1', '12345', '54321', '6', '6', '2016-09-03 15:07:14', '2016-09-03 15:07:15', '2016-09-03 15:07:14', '2016-09-03 15:07:15')) in Builder.php line 2117 at Builder->insert(array('member_user_id' => array('1', '1'), 'candidates_member_id' => array('12345', '54321'), 'candidates_district' => array('6', '6'), 'created_at' => array('2016-09-03 15:07:14', '2016-09-03 15:07:15'), 'updated_at' => array('2016-09-03 15:07:14', '2016-09-03 15:07:15'))) in VoteSubmitController.php line 60

So, for some reason I can't figure out, it is trying to use the array "row" key as a column name. Why is it interpreting the individual row key as a column in the DB? Thanks in advance.

您的代码应如下所示：

foreach($candidates_member_id as $key => $value)
{
    $arrData = array( 
        'member_user_id'        => $member_user_id[$key],
        'candidates_member_id'  => $candidates_member_id[$key], 
        'candidates_district'   => $candidates_district[$key], 
        'candidate_name'        => $candidate_name[$key], 
        'created_at'            => $created_at[$key],
        'updated_at'            => $updated_at[$key]                        
    );
    DB::table('primary_votes')->insert($arrData);
}

mysql 错误的原因是 $member_user_id, $candidates_member_id 是数组而不是标量值。您不能在 mysql 中插入数组。
