我有一个非常奇怪的问题。我有一个表单，其中几乎没有自动存在的图像，只是更改位置。这是正常的。但是当我尝试上传图片并提交表单时，它会将我注销。这是表格：
<div class="tab-pane" id="mainSlider" role="tabpanel">
{{ Form::open( array('url' => URL::to('my-affiliate/save-main-slider'), 'id' => 'frmEditPageSettings', 'files' => true ) ) }}
<div class="col-lg-12">
<div class="panel panel-default">
<div class="panel-heading">
<div class="push-right">
<button type="submit" style="visibility: hidden; margin-top: 0 !important" class="btn btn-primary btn-small"><i class="fa fa-fw fa-save"></i> SAVE SLIDER SETTINGS</button>
<select class="btn" style="float:right;width: 20%; padding: 5px;margin-top: 5px;" id="filterSlides">
<option value="3">Show All</option>
<option value="0">Show Active</option>
<option value="1">Show Inactive</option>
</select>
</div>
</div>
<div class="panel-body">
<div class="row">
<div class="col-lg-12">
<!-- Tab panes -->
<div class="tab-content">
<div class="" id="mainSlider" aria-expanded="true">
<div class="row">
<div class="col-lg-12">
<br /><br />
<div class="form-group">
<div class="row">
<div class="col-lg-6 dropzone" id="dropzone">
<div class="fallback">
<input name="file" type="file" multiple />
</div>
</div>
<div class="col-lg-6">
<ul class="images-path-container list-unstyled">
@if(count($mainslider) > 0)
<?php $i = 1; ?>
@foreach($mainslider as $image)
<li>
<div class="thumbnail" data-active="{{isset($image->show_image) ? $image->show_image : 1}}">
<a class="remove-image btn btn-danger btn-xs" href="javascript:void(0)"><i class="fa-fw fa fa-remove"></i></a>
<img src="{{ URL::to($imagesUrl.$image->imagename) }}" /><br />
<input type="text" class="form-control" name="url[{{$i}}]" value="{{$image->url}}" placeholder="Slider URL" /> @if($hasImages == true)
<input type="hidden" name="image[{{$i}}]" value="{{$image->imagename}}" />
<input type="hidden" name="existing_image[{{$i}}]" value="1" />
<select style="margin-top:5px;" class="form-control" name="show_image[{{$i}}]">
<option value="1" {{ $image->show_image == 1 ? 'selected' : ''}}>Active</option>
<option value="0" {{ $image->show_image != 1 ? 'selected' : ''}}>Inactive</option>
</select>
@else
<input type="hidden" name="image_to_copy[{{$i}}]" value="{{$imagesUrl.$image->imagename}}"/>
<select style="margin-top:5px;" class="form-control" name="show_image[{{$i}}]">
<option value="1">Active</option>
<option value="0">Inactive</option>
</select>
@endif
</div>
</li>
<?php $i++ ?>
@endforeach
@endif
</ul>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<div class="col-sm-12">
{{ Form::submit('SAVE', array('class' => 'btn btn-primary btn-small')) }}
</div>
{{ Form::close() }}
</div>
这是控制器：
public function saveMainSlider(){
AffiliateMainSlider::where('affiliate_id', Auth::user()->id)->delete();
if(Input::has('image') || Input::has('image_to_copy')){
if(Input::has('image')) {
$images = Input::get('image');
$show_image = Input::get('show_image');
$existing_image = Input::get('existing_image');
$urls = Input::get('url');
$i = 1;
AffiliateMainSlider::where('affiliate_id', Auth::user()->id)->delete();
foreach($images as $k => $image) {
$new_name = $image;
if(isset($existing_image[$k]) && $existing_image[$k] == 0) {
$tmp = explode('.', $image);
$extension = end($tmp);
$path = "images/main_slider/".Auth::user()->id."/";
$unique_name = sha1(str_random(10));
$new_name = $unique_name . '.' . $extension;
if (!File::exists($path)) File::makeDirectory($path);
Image::make("tmp/{$image}")->resize(1920, null, true, true)->save($path . $new_name);
}
$mainslider = new AffiliateMainSlider();
$mainslider->affiliate_id = Auth::user()->id;
$mainslider->imagename = $new_name;
$mainslider->url = $urls[$k];
$mainslider->position = $i;
$mainslider->show_image = isset($show_image[$k]) ? $show_image[$k] : 0;
$mainslider->save();
$i++;
}
}
if(Input::has('image_to_copy')){
$image_to_copy = Input::get('image_to_copy');
$urls = Input::get('url');
if(isset($image_to_copy) && count($image_to_copy) > 0){
foreach($image_to_copy as $img_counter => $image){
$old_image = str_replace("images/main_slider/", "", $image);
$path = "images/main_slider/".Auth::user()->id."/";
if (!File::exists($path)) File::makeDirectory($path);
File::copy($image, $path.$old_image);
$mainslider = new AffiliateMainSlider();
$mainslider->affiliate_id = Auth::user()->id;
$mainslider->imagename = $old_image;
$mainslider->url = $urls[$img_counter];
$mainslider->position = $img_counter;
$mainslider->show_image = 1;
$mainslider->save();
}
}
}
}
return Redirect::back()->with('success', 'Page settings saved successfully');
}
这也是路线，所以你可以看到我如何使用该方法：
Route::group(array('before' => 'auth|maintenance|force.ssl'),
function()
{
Route::post('/my-affiliate/save-main-slider', 'StoreController@saveMainSlider');
}
我使用Laravel 4.2。另外上传我使用dropzone.js，但它正确上传图像到tmp文件夹，所以没有问题。有谁知道可能是什么问题？这通常在我的本地工作，但不在测试或生产服务器上工作。 提前告知你们所有人的帮助
