wpdb->insert multiple record at once

$wpdb->query("INSERT INTO settings-table
            (option_name, option_value, option_created, option_edit, option_user)
            VALUES
            ('name-1', 'val-1', current_time('mysql'), current_time('mysql'), 'user-1'),
            ('name-2', 'val-2', current_time('mysql'), current_time('mysql'), 'user-2'),
            ('name-3', 'val-3',  current_time('mysql'), current_time('mysql'), 'user-3')")

In the query which you had posted, the column names shouldn't be in string.

$wpdb->insert function doesn't support multiple records to be inserted into single function call. You have to loop over your data and prepare the data to be inserted and then use $wpdb->insert into a loop and insert records one by one.

Instead, we can prepare insert query as follow and run a query only once.

So, if we want to insert 100 records, we need to run 100 insert queries if we want to use $wpdb->insert. And if we use following code, we need to run only 1 insert query.

Hope that helps.

function do_insert($place_holders, $values) {

    global $wpdb;

    $query           = "INSERT INTO settings-table (`option_name`, `option_value`, `option_created`, `option_edit`, `option_user`) VALUES ";
    $query           .= implode( ', ', $place_holders );
    $sql             = $wpdb->prepare( "$query ", $values );

    if ( $wpdb->query( $sql ) ) {
        return true;
    } else {
        return false;
    }

}

$data_to_be_inserted = array( array(
    'option_name'   => 'name-1', 
    'option_value'  => 'val-1', 
    'option_created'=> current_time('mysql'),
    'option_edit'   => current_time('mysql'),
    'option_user'   => 'user-1' 
),

array(
    'option_name'   => 'name-2', 
    'option_value'  => 'val-2', 
    'option_created'=> current_time('mysql'),
    'option_edit'   => current_time('mysql'),
    'option_user'   => 'user-2' 
),
array(
    'option_name'   => 'name-1', 
    'option_value'  => 'val-3', 
    'option_created'=> current_time('mysql'),
    'option_edit'   => current_time('mysql'),
    'option_user'   => 'user-3'
));

$values = $place_holders = array();

if(count($data_to_be_inserted) > 0) {
    foreach($data_to_be_inserted as $data) {
        array_push( $values, $data['option_name'], $data['option_value'], $data['option_created'], $data['option_edit'], $data['option_user']);
        $place_holders[] = "( %s, %s, %s, %s, %s)";
    }

    do_insert( $place_holders, $values );
}

I came up with this solution that extends the wpdb class so that it uses it's internal data processing functions:

<?php
class wpdbx extends wpdb {
  public function __construct() {
    parent::__construct(DB_USER, DB_PASSWORD, DB_NAME, DB_HOST);
  }

  public function insert_multiple($table, $data, $format = null) {
    $this->insert_id = 0;

    $formats = array();
    $values = array();

    foreach ($data as $index => $row) {
      $row = $this->process_fields($table, $row, $format);
      $row_formats = array();

      if ($row === false || array_keys($data[$index]) !== array_keys($data[0])) {
        continue;
      }

      foreach($row as $col => $value) {
        if (is_null($value['value'])) {
          $row_formats[] = 'NULL';
        } else {
          $row_formats[] = $value['format'];
        }

        $values[] = $value['value'];
      }

      $formats[] = '(' . implode(', ', $row_formats) . ')';
    }

    $fields  = '`' . implode('`, `', array_keys($data[0])) . '`';
    $formats = implode(', ', $formats);
    $sql = "INSERT INTO `$table` ($fields) VALUES $formats";

    $this->check_current_query = false;
    return $this->query($this->prepare($sql, $values));
  }
}

global $wpdbx;
$wpdbx = new wpdbx();
?>

You can then use it like this:

<?php
global $wpdbx;
$results = $wpdbx->insert_multiple(
  'settings-table',
  array(
    array(
      'option_name'   => 'name-1', 
      'option_value'  => 'val-1', 
      'option_created'=> current_time('mysql'),
      'option_edit'   => current_time('mysql'),
      'option_user'   => 'user-1' 
    ),
    array(
      'option_name'   => 'name-2', 
      'option_value'  => 'val-2', 
      'option_created'=> current_time('mysql'),
      'option_edit'   => current_time('mysql'),
      'option_user'   => 'user-2' 
    ),
    array(
      'option_name'   => 'name-1', 
      'option_value'  => 'val-3', 
      'option_created'=> current_time('mysql'),
      'option_edit'   => current_time('mysql'),
      'option_user'   => 'user-3'
    )
  )
);
?>

This Will Also Work

        $nameArray = array("name-1", "name-2", "name-3");
        $valueArray = array("val-1", "val-2" , "val-3");
        $userArray = array("user-1" , "user-2", "user-3");
        $maxRow= count($nameArray); // can use count of any array
        $setting_values = array();
        $time = current_time('mysql');

        for($x=0;$x<$maxRow; $x++){
            $SettingContext = [
                'option_name' => "'" . $nameArray[$x] . "'",
                'option_value' => "'" . $valueArray[$x] . "'",
                'option_created' => "'" . $time . "'",
                'option_edit' => "'" . $time . "'",
                'option_user' => "'" . $userArray[$x] . "'"
            ];
            $setting_values[] = "(" . implode(',', $SettingContext) . ")";
        }
        $settingSubmit = implode(',', $setting_values);
        $setting_save = $wpdb->query("
                INSERT INTO setting
                (option_name, option_value, option_created,option_edit, option_user)
                VALUES " . $settingSubmit
        );
