To implement a string handler in a Laravel model, you can create a custom accessor method that manipulates the string data before it is returned by the model. Here's an example of how to do this:

  1. Open your model file (usually located in the app directory).
  2. Inside your model class, create a method that will handle the string manipulation. This method should start with the keyword get followed by the name of the attribute you want to access. For example, if you want to add the prefix "Hello" to a property called name, you can create a method like this:
1
2
3
4
public function getFormattedNameAttribute()
{
    return "Hello, " . $this->name;
}


  1. To use this custom accessor, you can simply access the property formatted_name on an instance of your model. For example:
1
2
$user = User::find(1);
echo $user->formatted_name;


This will output "Hello, John" if the user's name is "John".


You can also create mutator methods to manipulate the string data before it is saved to the database. Mutators should start with the keyword set followed by the name of the attribute you want to set. For example, if you want to convert all names to uppercase before saving them to the database, you can create a method like this:

1
2
3
4
public function setNameAttribute($value)
{
    $this->attributes['name'] = strtoupper($value);
}


Now, whenever a new value is assigned to the name attribute of your model, it will automatically be converted to uppercase.


By using custom accessors and mutators, you can easily handle string manipulation in your Laravel models.
