用Laravel上传的多幅图像
用Laravel上传的多幅图像
提问于 2016-11-01 09:24:20
我试着用Laravel制作多个图像功能，但我已经收到了
“为foreach()提供的无效参数”
这是控制器中的函数。
public function uploadSubmit() {
$files = Input::file('image');
$file_count = count($files);
$gallery = 0;
foreach($files as $file) {
$gallery = new Gallery;
$rules = array('file' => 'required');
$validator = Validator::make(array('file'=> $file), $rules);
if($validator->passes()){
$filename = str_random(20);
$file->move(public_path() . '/uploads', $filename . '.' . $file->getClientOriginalExtension());
$imagePath = '/uploads/' . $filename . '.' . $file->getClientOriginalExtension();
$image = Image::make(public_path() . $imagePath);
$image->save();
$gallery ++;
$gallery->image = $imagePath;
$gallery->save();
}
}
if($gallery == $file_count){
return Redirect::to('/admin/upload')->with('message', 'image added.');
}
else
{
return Redirect::to('/admin/upload')->withInput()->withErrors($validator);
}
}当我var_dump($files);时，它返回NULL。
表格是
{{ Form::open() }}
{{ Form::file('image[]', array('multiple'=>true)) }}
<hr />
<button type="submit" class="btn btn-primary">upload</button>
{{ Form::close() }}我的路线：
Route::get ('/admin/upload', ['uses' => 'AdminController@upload', 'before' => 'admin']);
Route::post('/admin/upload', ['uses' => 'AdminController@uploadSubmit', 'before' => 'csrf|admin']);回答 1

创建窗体时使文件变为真
{！形式:打开(数组(‘路由’=>‘图片.上载’，‘方法’=> 'POST'，‘文件’=>真)！}
{!! Form::open(array('route' => 'image.upload', 'method' => 'POST', 'files' => true)) !!}
{{ Form::file('image[]', array('multiple'=>true)) }}
<hr />
<button type="submit" class="btn btn-primary">upload</button>
{{ Form::close() }}你的职能
public function uploadSubmit() {
$files = Input::file('image');
$file_count = count($files);
foreach($files as $file) {
$gallery = new Gallery;
$rules = array('file' => 'required');
$validator = Validator::make(array('file'=> $file), $rules);
if($validator->passes()){
$filename = str_random(20). '.' . $file->getClientOriginalExtension();
$file->move('uploads', $filename );
$gallery->image = $filename;
$gallery->save();
}
}
