How to make Laravel Nova like Fields - php

Question

I wanna create class for making fields, but in Laravel Nova this classes called like Text::make()->placeholder() and etc. This means that methods inside that class is static.
This is my field class:
class Field
{
private $field = [];
public function set($key, $value)
{
$this->field[$key] = $value;
}
public function get()
{
return $this->field;
}
}
class Text
{
private static $field;
public static function make($name)
{
self::$field = new Field;
self::$field->set('#saturn_type', 'string');
self::$field->set('#saturn_key', $name);
self::$field->set('#saturn_field', 'text');
return new Text;
}
public function placeholder($value)
{
self::$field->set('placeholder', $value);
return $this;
}
public function required()
{
self::$field->set('required', true);
return $this;
}
public function translate()
{
self::$field->set('translate', true);
return $this;
}
public function wysiwyg()
{
self::$field->set('wysiwyg', true);
return $this;
}
public function get()
{
return (array) self::$field->get();
}
}
and this is how i call it:
$fields = [
Text::make('name')->placeholder('Full Name'),
Text::make('email')->placeholder('Email'),
Text::make('password')->placeholder('Password'),
]
$lastArray = $fields->map(function ($field) {
return $field->get();
}
);
But when i call get() method for each item in this array to get array, each item returns the last item's name and placeholder because it is static. How can i solve this.

Answer 1

I found the solution. Actually my friend Nijat found ))
class Field
{
private $field = [];
public function set($key, $value)
{
$this->field[$key] = $value;
}
public function get()
{
return $this->field;
}
}
class Text
{
private $field;
public function __construct($name)
{
$this->field = new Field;
$this->field->set('#saturn_type', 'string');
$this->field->set('#saturn_key', $name);
$this->field->set('#saturn_field', 'text');
}
public static function make($name)
{
return new Text($name);
}
public function placeholder($value)
{
$this->field->set('placeholder', $value);
return $this;
}
public function required()
{
$this->field->set('required', true);
return $this;
}
public function translate()
{
$this->field->set('translate', true);
return $this;
}
public function wysiwyg()
{
$this->field->set('wysiwyg', true);
return $this;
}
public function get()
{
return (array) $this->field->get();
}
}
You just have to create constructor then call it in static method.

You can make Text inherit from Field and have a much simpler make method:
class Field
{
public static function make(...$arguments)
{
return new static(...$arguments);
}
// ...
}
This will instantiate the parent class (e.g. Text) and return it, allowing you to keep the chaining. In the methods you can then use $this-> as usual (instead of self::). And move the content of Text::make to the constructor:
class Text extends Field
{
public function __construct($name)
{
$this->set('#saturn_type', 'string');
$this->set('#saturn_key', $name);
$this->set('#saturn_field', 'text');
}
// ...
}
