我有一个允许用户上传几张图片的表单。我使用Form::file('images[]')。当我尝试在控制器中遍历这些图像时我得到了错误
Illegal offset type in isset or empty
这是我的控制器
public function up(Request $request) {
$user = $request->user();
$category=$request->get('category');
if($category == 'portfolio'){
$v = Validator::make($request->all(), [
//code
if ($v->fails()) {
return Redirect::back()->withErrors($v)->withInput();
}
$portfolio_data= Input::except('first_name','last_name','country','address','zip','state','city','image');
$user_data = Input::only('first_name','last_name','country','address','zip','state','city','image');
if ($user->user_portfolio == null){
$user_portfolio = new UserPortfolio();
$user_portfolio->fill($portfolio_data);
$user_portfolio->user_id = $user->id;
$user_portfolio->save();
} else{
$user->user_portfolio->fill($portfolio_data);
$user->user_portfolio->save();
}
}
**THIS IS WHERE I ITERATE THROUGH THE IMAGES**
$images = Input::only('images');
if(Input::hasFile($images)){
foreach($images as $image){
var_dump($image);exit;
$v = Validator::make($request->all(), [
'images' => 'mimes:jpeg,png,jpg,application/pdf',
]);
if ($v->fails()) {
return Redirect::back()->withErrors($v)->withInput();
}
$file = $request->file('image');
$ext = $file->getClientOriginalExtension();
$id = $user->id;
$url = 'https://s3-us-west-2.amazonaws.com/makers-marketing-dev/' . $id . '/profile/';
config('constants.url');
if ($category =='profile'){
$media = ($user->media->where('category','profile')->first());
if($media == null){
$media = Media::create();
}
}elseif ($category == 'portfolio') {
$media = Media::create();
}
$media->category = $category;
$media->user_id = $user->id;
$media->key = strtotime('now') . '.' . $ext;
$media->path = $url . $media->key;
$media->save();
$key = $media->key;
$s3 = AWS::createClient('s3');
$result = $s3->putObject(array(
'Bucket' => self::$_BUCKET_NAME,
'Key' => $user->id . '/profile/' . $key,
'SourceFile' => $file->getRealPath(),
'Metadata' => array(
'Owner' => $user->first_name .' ' . $user->last_name
)
));
}
}
return Redirect::back();
}

它从来没有使var_dump($images)，我只是抛出这个错误。
我就是这么做的。而不是使用条件:
if(Input::hasFile($images)){
//code
}
:
if(!empty($images)){
//code
}
