如果字段是输入类型文件，则laravel中的required_if验证不会给出错误

Question

我有一个表单，我有5个文本字段和2个输入类型文件字段。对于所有7个字段，我已经在laravel中编写了自定义验证规则，如果类型是业务我想要所有字段，所以我在所有字段中使用required_if，对于文本字段它正在工作但是对于图像（输入类型文件）它不起作用它始终被视为文件存在于请求中，如果文件未上传，当我将其更改为required时它不会给出任何错误，它只会给我输入类型文件的错误。

public function rules()
{
    return [
        'country'       => 'required_if:type,business',
        'country2'      => 'required_if:type,business',
        'company'       => 'required_if:type,business',
        'number' => 'required_if:type,business',
        'expiry' => 'required_if:type,business',
        'profile_pic'       => 'required_if:type,business  |  mimes:jpeg,jpg,png,pdf',
        'document_pic'      => 'required_if:type,business  |  mimes:jpeg,jpg,png,pdf',
    ];
}

Answer 1

你可以试试这个：

public function rules()
{
    return [
        'country'       => 'required_if:type,business',
        'country2'      => 'required_if:type,business',
        'company'       => 'required_if:type,business',
        'number'        => 'required_if:type,business',
        'expiry'        => 'required_if:type,business',
        'profile_pic'   => 'required_if:type,business|image',
        'document_pic'  => 'required_if:type,business|image',
    ];
}

Answer 2

由于额外的空间无效规则，问题即将来临。删除了所需的if和mime类型之间的空格及其正常工作。

public function rules()
{
    return [
        'country'       => 'required_if:type,business',
        'country2'      => 'required_if:type,business',
        'company'       => 'required_if:type,business',
        'number' => 'required_if:type,business',
        'expiry' => 'required_if:type,business',
        'profile_pic'       => 'required_if:type,business|mimes:jpeg,jpg,png,pdf',
        'document_pic'      => 'required_if:type,business|mimes:jpeg,jpg,png,pdf',
    ];
}
