[php] laravel 5.4 upload image

Intervention Image is an open source PHP image handling and manipulation library http://image.intervention.io/

This library provides a lot of useful features:

Basic Examples

// open an image file
$img = Image::make('public/foo.jpg');

// now you are able to resize the instance
$img->resize(320, 240);

// and insert a watermark for example
$img->insert('public/watermark.png');

// finally we save the image as a new file
$img->save('public/bar.jpg');

Method chaining:

$img = Image::make('public/foo.jpg')->resize(320, 240)->insert('public/watermark.png');

Tips: (In your case) https://laracasts.com/discuss/channels/laravel/file-upload-isvalid-returns-false

Tips 1:

// Tell the validator input file should be an image & check this validation
$rules = array(
  'image' => 'mimes:jpeg,jpg,png,gif,svg  // allowed type
              |required                  // is required field
              |max:2048'               // max 2MB
              |min:1024               // min 1MB
  );
// validator Rules
$validator = Validator::make($request->only('image'), $rules);

// Check validation (fail or pass)
if ($validator->fails())
{
    //Error do your staff
} else
{
    //Success do your staff
};

Tips 2:

   $this->validate($request, [
        'input_img' => 
                 'required
                  |image
                  |mimes:jpeg,png,jpg,gif,svg
                  |max:1024',
    ]);

Function:

function imageUpload(Request $request) {

   if ($request->hasFile('input_img')) {  //check the file present or not
       $image = $request->file('input_img'); //get the file
       $name = "//what every you want concatenate".'.'.$image->getClientOriginalExtension(); //get the  file extention
       $destinationPath = public_path('/images'); //public path folder dir
       $image->move($destinationPath, $name);  //mve to destination you mentioned 
       $image->save(); //
   }
}
