Question

我正在尝试使用ajax和laravel将图像上传到数据库和文件夹，但是我收到的错误如call to a member function getclientoriginalextension on string，而且我的控制器图像路径中的值只是没有来。

我的观点：

<form role="form" name="campaignForm" id="campaignForm" action="" method="post"  enctype="multipart/form-data">


    <input type="text" name="project_name" autocomplete="off" id="project_name" placeholder="Company name" class="form-control">

    <input type="text" name="website_url" id="website_url" autocomplete="off" placeholder="http://www.yourdomain.com" class="form-control">
    <input type="file" name="image" id="image" autocomplete="off" placeholder="" class="form-control">

    <input type="text" name="location" id="location" autocomplete="off" placeholder="Enter the location you want to target" class="form-control">

    <input type="text" name="group" id="group" autocomplete="off" placeholder="Group (optional)" class="form-control">
    <button type="submit" id="btn-save" value="add"  class="btn actionBtn btn-primary">
</form>

我的ajax：

$("#btn-save").click(function (e) {
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
        }
    })

    e.preventDefault(); 

    var formData = {
        project_name: $('#project_name').val(),
        website_url: $('#website_url').val(),
        location: $('#location').val(),
        group: $('#group').val(),

        image : $('#image').val(),
    }


    $.ajax({

        type: type,
        url: my_url,
        data: formData,
        dataType: 'json',
        success: function (data) {
            console.log(data);

        },
        error: function (data) {
            console.log('Error:', data);
        }
    });
});

控制器：

    public function campaign(Request $request){


    $task = new projects();

    $task->project_name = trim($request->project_name);
    $task->website_url = trim($request->website_url);
    $task->location = trim($request->location);
    $task->group = trim($request->group);


    $file = trim($request->image);

    if ($request->hasFile($file)) {
    $destinationPath = 'images'; // upload path
    $extension = $file->getClientOriginalExtension(); // getting image extension
    $fileName = rand(11111,99999).'.'.$extension; // renameing image
    $file->move($destinationPath, $fileName);

    $task->image = $fileName; 
  }   

  dd($task);

}

任何帮助都将不胜感激。谢谢。

看起来Laravel没有收到上传的图片。 $request->image应该是UploadedFile类的实例，但在您的情况下，它只是"C:\fakepath\custom-image.jpg"

之类的字符串

尊重this answer，试试这个：

$("#btn-save").click(function (e) {
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
        }
    });

    e.preventDefault();

    var form = document.forms.namedItem("campaignForm"); // high importance!, here you need change "yourformname" with the name of your form
    var formData = new FormData(form); // high importance!

    $.ajax({
        type: type,
        url: my_url,
        dataType: "json", // or html if you want...
        contentType: false, // high importance!
        data: formData, // high importance!
        processData: false, // high importance!
        success: function (data) {
            console.log(data);

        },
        error: function (data) {
            console.log('Error:', data);
        }
    });
});

使用ajax laravel 5.4在数据库和文件夹中上传图像
