How to Create Multiple Rows Using Laravel Eloquent

When working with Laravel, you may often find yourself needing to create multiple rows in a database table at once. This can be achieved using Laravel's query builder or Eloquent ORM. In this article, we will explore how to do this.

One common scenario is when you have an array of data that you want to insert into the database. For example, let's say you have a multidimensional array called `createMultipleUsers` that contains multiple user objects:

```php

$users = '

''name' => 'John', 'email' => 'john@example.com'',

''name' => 'Jane', 'email' => 'jane@example.com'',

// ...

```

To create multiple rows using Eloquent, you can use the `create` method and pass in your array of attributes:

```php

User::insert($users);

```

However, this will only work if each attribute in the array matches the column name in your table. If you have a large number of columns or dynamic column names, this approach may not be practical.

Another way to create multiple rows using Laravel's query builder is by using the `table` method and specifying the columns and values as separate arrays:

```php

DB::table('users')->insert('

''name' => 'John', 'email' => 'john@example.com'',

''name' => 'Jane', 'email' => 'jane@example.com'',

// ...

');

```

This approach gives you more flexibility in terms of specifying the columns and values, but it can be less efficient than using Eloquent's `create` method.

Eloquent also provides an `upsert` method that allows you to update or create records in a single, atomic operation. This can be useful when you need to insert multiple rows, but some of them may already exist in the database:

```php

User::upsert($users, ''name', 'email'');

```

In this example, the `upsert` method will update existing records that match the `name` and `email` columns, and create new records for those that do not exist.

When working with dynamic data or user input, it's important to ensure that you are properly sanitizing and validating your data to prevent SQL injection attacks. Laravel provides a fluent query builder that uses PDO parameter binding to protect against these types of attacks.

In conclusion, creating multiple rows using Laravel Eloquent is a common task that can be achieved using the `create` method, query builder, or `upsert` method. By choosing the right approach for your specific use case, you can efficiently and securely insert data into your database.
