Laravel upload image via another URL and store it in the database

Question

I want to upload (and update) an image via Laravel.

I want an existing image name in my database to be replaced by a new one.

So I have this in my controller:

public function UpdatePic()
    {
        $rules = array(
            'image' => 'required',
            );

        $random = str_random(40);
        $validator = Validator::make(Input::all(), $rules);

        //process the storage
        if ($validator->fails())
        {
            Session::flash('error_message', 'Fout:' . $validator->errors());
            return Redirect::to('admin/user#tab_2-2')->withErrors($validator);
        }else{

            //define the new random generated string for imagename
            $imagename = str_random(40) . '.' . Input::file('image')->getClientOriginalName();
            //store
            $userimg            = UserImage::find(1);
            $userimg->img       = $imagename;
            $userimg->save();

            //save the image
            $destinationPath = 'public/img/user_img';

            if (Input::hasFile('img'))
            {
                $file = Input::file('img');
                $file->move('public/img/user_img', $imagename);
            }
            //redirect
            Session::flash('success', 'Uw afbeelding is succesvol veranderd!');
            return Redirect::to('admin/user#tab_2-2');

        }
    }

The problem is, When I Got this I'm getting this error:

Creating default object from empty value

I have a post route wich one looks like this:

Route::post('updateuserpic', 'UserController@UpdatePic');

So my view looks like this:

{{ Form::open(array('url' => 'admin/updateuserpic', 'files' => true)) }}
                                                    <div class="form-group">

                                                {{ Form::close() }}

My Class only has this stuff:

<?php

class UserImage extends Eloquent{

    protected $table = 'user_image';

    public $timestamps = false;

}

I think the image disappears because I'm using that route, but I don't know how to fix it... It doesn't store the image in the folder and it doesn't store the random name in the database..

Thanks people!

Kindest regards,

Robin

try:

validator::make(Input::file('image'), $rules);

and change the Input from img to image:

        if (Input::hasFile('image'))
        {
            $file = Input::file('image');
            $file->move('public/img/user_img', $imagename);
        }

also to edit the data in the databse, do:

 UserImage::find(1)->update(['img' => $imagename]);

no need to open a object

also your route should be

Route::post('admin/updateuserpic', 'UserController@UpdatePic');

in your blade:

{{ Form::open(array('url' => 'admin/updateuserpic','method' => 'post' ,'files' => true)) }}

Update for comment

$file = array('image' => Input::file('image');
validator::make($file , $rules);

TBH, i think your code shouldn't be so complected. your Routes are fine, try changing your controller to:

<?php

 public function UpdatePic(){

//first, I'll just do the file validation
$validator =  Validator::make(array( 'image' => Input::file('image')), 
                                array('image' => 'required|image'));


if($validator->fails()){

        //return error code
        Session::flash('error_message', 'Fout:' . $validator->errors());
        return Redirect::to('admin/user#tab_2-2')->withErrors($validator);

    }else{

        //update the image name
        $imageName = str_random(40) . '.' . Input::file('image')->getClientOrignalName();

        //store
        UserImage::find(1)->update(['img' => $imageName]);

        //now move that image to the new location
        $file = Input::file('image');
        $file->move('public/img/user_img/', $imageName);

        //now we have done, lets redirect back
        Session::flash('success', 'Uw afbeelding is succesvol veranderd!');
        return Redirect::to('admin/user#tab_2-2');

            }
 }

?>

The error I get now is this one: Argument 1 passed to Illuminate\Validation\Factory::make() must be of the type array, object given, called in C:\xampp\htdocs\RPR\system\vendor\laravel\framework\src\Illuminate\Support\Facades\Facade.php on line 211 and defined

I'll try it out tomorrow. If it works, I'll approve the answer!

I tried the code, but now I have another error Call to a member function update() on null

Ashley Wrench Over a year ago

that should not be spat back, unless there is error in code somewhere else.

I use anonter url to post the image? So my controller gos from the URL http://192.168.0.233/RPR/admin/user to http://192.168.0.233/RPR/admin/updateuserpic I don't know if that is the problem.

The solotion I found with some help of other people wherefor thanks!

Controller:

public function UpdatePic(){

//first, I'll just do the file validation
$validator =  Validator::make(array( 'image' => Input::file('image')), 
                                array('image' => 'required|image'));


if($validator->fails()){

        //return error code
        Session::flash('error_message', 'Fout:' . $validator->errors());
        return Redirect::to('admin/user#tab_2-2')->withErrors($validator);

    }else{

        //update the image name
        $imageName = str_random(40) . '.' . Input::file('image')->getClientOriginalName();


        //store
        UserImage::where('uid', '=', Auth::user()->id)->update(['img' => $imageName]);

        //now move that image to the new location
        $file = Input::file('image');
        $file->move('public/img/user_img/', $imageName);

        //now we have done, lets redirect back
        Session::flash('success', 'Uw afbeelding is succesvol veranderd!');
        return Redirect::to('admin/user#tab_2-2');

            }
 }

The view is just an normal input.

Hope this can help other people!

Special thanks to Ashley Wrench

I used raw PHP for the job

$source = $data['Poster']; /* URL of remote image */

$dest = "posters/".$data['Year']; /* Path */
if (!file_exists($dest)) {
    mkdir($dest, 0777, true); /* Create directory */
}
$dest .= "/".$data['imdbID'].".jpg"; /* Complete file name */

/* Copy the file */
copy($source, $dest);
