Question

我有3个输入用于选择具有以下名称的文件：

docs['selfie']
docs['id_card']
docs['bank_card']

我想检查docs['selfie']是否有文件返回yes，否则是否返回no。但总是返回no

功能：

    public function Document(Request $request)
    {
        if ($request->hasFile("docs['selfie']")) {
            return "yes";
        }
        else {
            return "no";
        }
    }

和表格：

{{ html()->form('POST', route('frontend.user.send.document'))->class('form-horizontal')->Attribute('enctype','multipart/form-data')->open() }}
<div class="row">
    <div class="col-md-12">
        <div class="form-group row">
            <label class="col-form-label col-lg-2">id card</label>
            <div class="col-lg-10">
                <div class="custom-file">
                    <input type="file" class="custom-file-input" id="National_Card" name="docs['id_Card']">
                    <label class="custom-file-label" for="docs">chose file</label>
                </div>
            </div>
        </div>
    </div>
    <div class="col-md-12">
        <div class="form-group row">
            <label class="col-form-label col-lg-2">bank card</label>
            <div class="col-lg-10">
                <div class="custom-file">
                    <input type="file" class="custom-file-input" id="Bank_card" name="docs['bank_card']">
                    <label class="custom-file-label" for="Bank_card">chose file</label>
                </div>
            </div>
        </div>
    </div>
    <div class="col-md-12">
            <div class="form-group row">
                <label class="col-form-label col-lg-2">selfie</label>
                <div class="col-lg-8">
                    <div class="custom-file">
                        <input type="file" class="custom-file-input" id="Selfie" name="docs['selfie']">
                        <label class="custom-file-label" for="Selfie">chose file</label>
                    </div>
                </div>
                <div class="col-lg-2">
                    <button type="button" class="btn btn-primary"  data-toggle="modal" data-target="#selfie_modal">see example</button>
                </div>                
            </div>
        </div>
    </div>
    <div class="row">
        <div class="col">
            <div class="form-group mb-0 clearfix">
                {{ form_submit("send docs" . ' ') }}
            </div><!--form-group-->
        </div><!--col-->
    </div><!--row-->
{{ html()->form()->close() }}

Answer 1

尝试

 public function Document(Request $request)
    {
        if ($request->hasFile("docs.selfie")) {
            return "yes";
        }
        else {
            return "no";
        }
    }

检查请求数据

 echo "<pre>"; 
 print_r($request->all()); 
 die;

Answer 2

您不必在HTML名称中使用引号：

<input type="file" class="custom-file-input" id="Selfie" name="docs[selfie]">
// instead of name="docs['selfie']"

将名称的所有引号删除到方括号中，则可以简单地使用：

dump($request->hasFile('docs.selfie'));

它将起作用

hasFile函数在Laravel5.8中不起作用
