php – Laravel只验证发布的项目并忽略其余的验证数组

对于使用Laravel 4.1的项目,我有一个我想要解决的UI问题.

一些输入在模糊时对laravel进行ajax调用,并且工作正常.它只是发送它的价值.在laravel我然后检查验证器.

public function validate() {
        if(Request::ajax()) {
            $validation = Validator::make(Input::all(), array(
                'email' => 'unique:users|required|email', 
                'username' => 'required'
            ));
            if($validation->fails()) {
                return $validation->messages()->toJson();
            }
            return "";
        }
        return "";
    }

虽然这有效,但json字符串还包含我无需检查的字段.确切地说,这是我得到的反馈:

{"email":["The email field is required."],"username":["The username field is required."]}

但看到它是模糊的我只想要一个我实际检查的那个.所以,如果我模糊电子邮件,我希望返回:

{"email":["The email field is required."]}

现在我知道这显然是因为我的数组包含多个字段,但我不想为我曾经做过的每个可能的输入编写完整的验证.

我的问题是:我能以某种方式只获得实际发布的post值的返回值,即使该值可能为null并且不能返回其余的数组.

最佳答案
试试这个(未经测试,如果不起作用,请随时评论/ downvote):

// Required rules, these will always be present in the validation
$required = ["email" => "unique:users|required|email", "username" => "required"];

// Optional rules, these will only be used if the fields they verify aren't empty
$optional = ["other_field" => "other_rules"];

// Gets input data as an array excluding the CSRF token
// You can use Input::all() if there isn't one
$input = Input::except('_token');

// Iterates over the input values
foreach ($input as $key => $value) {
    // To make field names case-insensitive
    $key = strtolower($key);

    // If the field exists in the rules, to avoid
    // exceptions if an extra field is added
    if (in_array($key, $optional)) {
        // Append corresponding validation rule to the main validation rules
        $required[$key] = $optional[$key];
    }
}

// Finally do your validation using these rules
$validation = Validator::make($input, $required);

将所需字段添加到$required数组,键是POST数据中字段的名称,以及$optional数组中的可选字段 – 只有在提交数据中存在该字段时才会使用可选字段.
