Laravel 5上传和显示图像

Question

基本上我想上传一个图像并将其显示给用户，在图像被选中的时刻，什么也没有发生，我得到了没有错误的错误或其他任何东西，我想知道发生了什么。

这里是我的代码：

<form action="{{ action('BuilderController@testing') }}" role="form" method="POST"> 
    <input class="form-control filestyle margin images" data-input="false" type="file" data-buttonText="Upload Logo" data-size="sm" data-badge="false" /> 
</form> 

<div class="logo"> 
    <img class="images" id="image" src="#" alt="Your Logo"/> 
</div> 

控制器：

public function testing() { 
    if(Input::file()) 
    { 
     $image = Input::file('photo'); 
     $filename = time() . '.' . $image->getClientOriginalExtension(); 
     $path = public_path('images/' . $filename); 
     Image::make($image->getRealPath())->resize(200, 200)->save($path); 
     $user->image = $filename; 
     $user->save(); 
    } 
} 

Answer 1

你必须在HTML中使用此代码enctype="multipart/form-data"：

<form id="uploadbanner" enctype="multipart/form-data" method="post" action="#"> 
    <input id="fileupload" name="myfile" type="file" /> 
    <input type="submit" value="submit" id="submit" /> 
</form> 

Answer 2

你必须移动图像文件夹的存储和刀片名称在表中，尝试更改动作以路由url例外action =“{{url（'add/image'）}}”

航线为例

Route::post('add/image', 'your_controller_Image@testing'); 

控制器

public function testing(Request $request) { 

    $insert_image = new App\NameTable(); 

    $file = $request->file('myfile_input'); 
    $path = public_path().'/images'; 
    $filename = time().'.'.$file->getClientOriginalExtension(); 

    if($file->move($path,$filename)) 
    { 
     $insert_image->column_name = $request->file($filename); 
     $insert_image->save() 
    } 
} 

形式

<form enctype="multipart/form-data" method="post" action="{{ url('add/image')}}"> 
<input id="fileupload" name="myfile_input" type="file" /> 
<input type="submit" value="submit" id="submit" /> 
</form> 

Answer 3

使用AJAX没有提交添加图片的形式自动提交时选择图像

路线

个

Route::post('add/image', 
[ 
    'as'=>'test.image.add', 
    'uses'=>'Controller@testing' 
]); 

控制器

public function testing(Request $request) 
{ 
    $insert_image = new App\NameTable(); 

    $file = $request->file('file_upload'); 
    $path = public_path().'/images'; 
    $filename = time().'.'.$file->getClientOriginalExtension(); 

    if($file->move($path,$filename)) 
    { 
    $insert_image->column_name = $request->file($filename); 
    $insert_image->save(); 
    Session::flash('messageSuccess',"Success, add image successfully !!"); 
    return back(); 
    } 

} 

查看

<form method="post" id="formimgInp" action="{{ route('test.image.add') }}" enctype="multipart/form-data"> 

    <input type="hidden" name="_token" value="{{ csrf_token() }}" /> 
    <input type="file" name="file_upload" class="img_ava" id="imgInp" /> 

</form> 

<script> 
document.getElementById("imgInp").onchange = function() { 
    document.getElementById("formimgInp").submit(); 
} 
</script>
