嵌套数组中奇怪的 Laravel 验证

Question

我尝试了一些验证规则，例如：Boolean和Requiredfile以及nested array字段，但总是失败

例如，我尝试像这样创建表单请求：

<?php

namespace App\Http\Requests\Test;

use Illuminate\Foundation\Http\FormRequest;

class Test extends FormRequest
{
    public function validationData()
    {
        return [
            'booleanField' => $this->boolean("booleanField"),
            'fileField' => $this->boolean("fileField"),
            'arrayField' => $this->input("arrayField"),
            'arrayField.*.booleanField' => $this->boolean("arrayField.*.booleanField"),
            'arrayField.*.fileField' => $this->file("arrayField.*.fileField"),
        ];
    }

    public function rules(): array
    {
        return [
            "booleanField" => ["required", "boolean"], // <= works as expected
            "fileField" => ["required", "file", "mimes:jpg,png,jpeg,docx,xlsx,zip", "max:5120"], // <= works as expected
            "arrayField" => ["required", "array"],
            "arrayField.*.booleanField" => ["required", "boolean"], // <= not working, always returning error "The arrayField.0.booleanField field must be true or false."
            "arrayField.*.fileField" => ["required", "file", "mimes:jpg,png,jpeg,docx,xlsx,zip", "max:5120"], // <= not working, always returning error "The arrayField.0.fileField is required."
        ];
    }
}

这就是我发现的。我不知道其他规则是否也不起作用。

Laravel 版本 11.31.0。 谢谢你。

方法

validationData

应该是 you 访问将要验证的数据的一种方式。它并不意味着覆盖数据。

当

FormRequest

被解析时，应用程序（或容器，如果您愿意）将调用其

validateResolved

方法。

public function validateResolved()
{
    $this->prepareForValidation();

    if (! $this->passesAuthorization()) {
        $this->failedAuthorization();
    }

    $instance = $this->getValidatorInstance();

    if ($this->isPrecognitive()) {
        $instance->after(Precognition::afterValidationHook($this));
    }

    if ($instance->fails()) {
        $this->failedValidation($instance);
    }

    $this->passedValidation();
}

如果您想修改即将验证的数据，您正在寻找的方法是

prepareForValidation

。据我所知，你不能像通配符一样使用 * 。

class Test extends FormRequest
{

    /**
     * Prepare the data for validation.
     *
     * @return void
     */
    public function prepareForValidation(): void
    {
        // please check this and make sure the data you're sending looks like the data you're trying to validate.
        dd($this->validationData());

        $this->merge([
           'key' => 'value,
           ...
        ]);
    }

    ...
}
