javascript - Ajax请求不传递表单文件

Question

我遇到的问题是表单无法传递一个变量。

我的 table :

Schema::create('projects', function(Blueprint $table)

    {
        $table->increments('id');
        $table->string('slug');
        $table->integer('order');
        $table->integer('public')->default(1);
        $table->string('pathheader')->default('/');
        $table->string('pathhome')->default('/');
        $table->timestamps();
    });

我有这个 Blade ，有一些形式(我将把ajax放在这段代码后面)

@extends('cms.public.layouts.default')
@section('content')
<div class="col-md-10">
    <h3 style="letter-spacing:40px;text-align:center;color:f15d5e;">PROYECTOS</h3>
</div>

<div id="listall"> <!-- DIV TO LIST ALL THE PROJECTS START HERE -->
        <div class="col-md-2" style="padding:20px;">
          <button type="button" id="buttoncreate" class="btn btn-danger">Crear Proyecto</button>

        </div>
                      <table class="table">
                  <thead style="color:white">
                    <tr>
                      <th>Id</th>
                      <th>Slug</th>
                      <th>Order</th>
                      <th>Public</th>
                      <th>Fecha creación</th>
                      <th>Fecha ultima actualización</th>
                      <th><span class="glyphicon glyphicon-cog"></span></th>
                    </tr>
                  </thead>
                  <tbody style="color:white">
                  @foreach ($projects as $key => $project)
                    <tr>
                      <th>{{$project->id}}</th>
                      <td>{{$project->slug}}</td>
                      <td>{{$project->order}}</td>
                      <td>{{$project->public}}</td>
                      <td>{{ date('M j, Y', strtotime($project->created_at))}}</td>
                      <td>{{ date('M j, Y', strtotime($project->updated_at))}}</td>
                      <td><a href="{{ route('admin.projects.show', $project->id)}}" class="btn btn-info btn-sm">View</a> <a href="{{ route('admin.project.edit', $project->id)}}" class="btn btn-success btn-sm">Edit</a>
                  @endforeach
                    </tr>
                  </tbody>
                </table>
  <br><br>

            <br><br><br>

          </div>
        </form>
</div>

</div>
@stop

这是 ajax 代码:

//Javascript view /projects/menu.blade.php
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
$(document).ready(function(){
    $("#buttoncreate").click(function(){
        $("#listall").hide();
        $("#form1").fadeIn(1000);

    });

    $("#createprojectsubmit").click(function(){
        $("#myForm").submit();
    });

    $("#myForm").submit(function(e){
        e.preventDefault();
        $.ajax({
            url:'/admin/projects/postUpload',
            type:'post',
            data:$('#myForm').serializeArray(),
            success: function(){
                $("#form1").fadeOut(1000);
                $("#form2").fadeIn(1000);
            }
        });
    });
});

执行 ajax 时，我检查表单数据，它会显示以下几行:

_token:ymzuWLO6I0nl7z5CQEBNJ4Af51NfriftjP1swWmH
slug:Test3
order:1
public:1

它给了我一个错误:

Call to a member function getRealPath() on null

at FilesystemAdapter->putFileAs('Test3', null, 'header.png')

我也放置了 Controller 代码:

public function storeProject(Request $request)
        {
        $project = new Project();
        $project->slug = $request->input("slug");
        $project->order = $request->input("order");
        $project->public = $request->input("public");
        $project->pathheader = $request->file('pathheader');
        $project->pathhome = $request->file('pathhome');
        \Storage::disk('public')->makeDirectory($project->slug);
        \Storage::disk('public')->putFileAs($project->slug,$project->pathheader,'header.png');
        \Storage::disk('public')->putFileAs($project->slug,$project->pathhome,'home.png');
        $project->save();
        }

问题出在 $project->pathhome 和 $project->pathheader 上，它们为空，知道为什么吗？

非常感谢，如果需要更多信息，请询问。

您可以尝试使用FormData()吗:

$("#myForm").submit(function(e){
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    $.ajax({
        url: '/admin/projects/postUpload',
        type: 'POST',
        data: formData,
        async: false,
        success: function (data) {
            $("#form1").fadeOut(1000);
            $("#form2").fadeIn(1000);
            //alert(data);
        },
        cache: false,
        contentType: false,
        processData: false
    });

    return false;
});

以上是示例代码，您可以对其进行修改。
