Laravel Form Request merge new variable does not validated-CodePudding

I am trying to get the new validated request after merging the request with new variable. It can be found in $request->all() but not in $request->validated(). I understand that the new variable doesnt not being validated with the request but is there anyway to get the new form request after merged?

Before Merge: dd($request->all());

array:2 [▼
  "Name" => "Jack"
  "Age"  => "12" 
]

Merge new variable with $request

$request->merge(['Fruit' => 'apple']);

After merge: dd($request->all());

array:3 [▼
  "Name" => "Jack"
  "Age"  => "12" 
  "Fruit"  => "Apple" 
]

After merge: dd($request->validated());

array:3 [▼
  "Name" => "Jack"
  "Age"  => "12" 
]

Request Rules

public function rules()
    {
        return [
            'Name' => 'nullable',
            'Age' => 'nullable',
            'Fruit' => 'nullable',
        ];
    }

CodePudding user response：

Add a request variable like this:

$request->request->add(['Fruit' => 'apple']);

CodePudding user response：

You can use the method prepareForValidation, like this in your Request class:

protected function prepareForValidation()
{
    $this->merge([
        'Fruit' => 'Apple',
    ]);
}

<?php

namespace App\Http\Requests;

class RequestExample extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return auth()->check();
    }

    /**
     * @return Validator
     */
    protected function getValidatorInstance()
    {
        $this->modifyRequestExampleRecords();
        return parent::getValidatorInstance();
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'Name'  => 'nullable',
            'Age'   => 'nullable',
            'Fruit' => 'nullable',
        ];
    }

    /**
     * @return void
     */
    protected function modifyRequestExampleRecords(): void
    {
        $this->request->add([
            "Fruit" => "apple"
        ]);
    }
}

Pass RequestExample $request as your method parameter. And then write dd($request->validated()); or dd($request->all());. You will get the 3 properties as well. But please try to avoid $request->all();. Because, SQL injection can be occurred by using this. So better to use $request->validated(); everywhere.

Have a good day.
