An article explaining laravel's save method in detail

Laravel is a popular PHP framework that uses some flexible and powerful tools to generate clean code and operate databases efficiently. Using the save() method in Laravel is a quick and easy way to create new database records.

save() method working mechanism

save() method allows us to save data to the database with minimal code. In Laravel, even if we use low-level $queryBuilders to operate the database, the save() method can create new records with minimal code.

The specific execution method of Laravel's save() method is as follows:

1. First, Laravel will check whether the record object exists and try to find a record matching the object in the database. If it is not found, a new record is created.
2. Secondly, Laravel will use $fillable or $guarded arrays to find properties that can be saved. This way, we can ensure our save operations are secure without exposing sensitive data.
3. Finally, Laravel creates the SQL statement to build and attempts to insert the data into the database.

Use the save() method to save data

In order to use the save() method in Laravel, we need to do the following steps:

1. Create A new object and assign the data to be saved to it. For example, we can create a new object in the User model:

$user = new User;

2. Set properties and save them to the database. For example, we can set the properties of the user record:

$user->name = 'Tom';
$user->email = 'tom@example.com';

3. Call the save() method to save the data, as shown below:

$user->save();

Use the fill() method

In Laravel, we can also use the fill() method to set the properties of the model. Every model must define a $fillable property that contains assignable properties.

For example, we can define the $fillable array in the User model:

protected $fillable = ['name', 'email', 'password'];

Then Before saving the data, use the fill() method to fill the object's properties:

$user->fill(['name' => 'John', 'email' => 'john@example .com', 'password' => 'password']);

Finally, save the data:

$user->save();

Use create () Method

Laravel's create() method is another method to quickly create new records. It uses the fill() and save() methods to reduce the amount of our code.

For example, we can use the create() method in the User model to create a new user:

User::create([

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

]);

Summary

Laravel’s save() method provides us with a fast and simple way to save data to the database. By using this method, we can minimize the size of our code and use $fillable and $guarded arrays to keep our data operations safe. If we want an easier way to create new records, we can also use the create() method.
