Check this code:

search.blade.php

<form action="{{ route('search') }}" class="form-image-upload" method="POST" enctype="multipart/form-data">
    {!! csrf_field() !!}

    <div class="col-md-5">

ImageGalleryController.php

public function search()
    {
        $images = \App\ImageGallery::get();

        return view('search', compact('images'));
    }

    public function order(Request $request)
    {

        $data = $request->all();

        $images = \App\ImageGallery::when($data['type'], function ($query, $type) {
            return $query->where('type', $type);
        })->
        when($data['fc'], function ($query, $fc) {
            return $query->orWhere('fc', $fc);
        })->
        when($data['yc'], function ($query, $yc) {
            return $query->orWhere('yc', $yc);
        })->
        when($data['wc'], function ($query, $wc) {
            return $query->orWhere('wc', $wc);
        })->
        when($data['sc'], function ($query, $sc) {
            return $query->orWhere('sc', $sc);
        })
        ->get();

        return view('result', compact('images'));
    }

This is the database structure:

This is the full working code on my local system.

This is web.php file

Route::get ('search', 'ImageGalleryController@search');
Route::post('search', 'ImageGalleryController@order')->name('search');

Add csrf token in your form.

@csrf

Change order function as:

public function order(Request $request) {

$data = $request->all();

$images = ImageGallery::where([
    ['type', $data['type']],
    ['wc',$data['type']],
    ['fc',$data['fc']],
    ['yc',$data['yc']],
    ['sc',$data['sc']]
])->get();
return view('result', compact('images'));

}

Give name method to route:

Route::post('search', 'ImageGalleryController@order')->name('search');

Dear @Ankur Mishra Thank you so much for answer and I'm sorry to late reply. Array to string conversion Error message is gone now. but I have another problem.I change my code as you taught me. and now I got this error "Facade\Ignition\Exceptions\ViewException Call to a member function count() on string " so I tryed to check what is happing, I add ->toSql(); var_dump($images); Then I got string(100) "select * from image_gallery where (type = ? and wc = ? and fc = ? and yc = ? and sc = ?)" I selected all value but why I got this query?

Ankur Mishra Over a year ago

Change $images->count() to $images->first() in blade.

greeniron Over a year ago

Dear @Ankur Mishra I changed. now I got this error Facade\Ignition\Exceptions\ViewException Call to a member function first() on string. And query also same string(100) "select * from image_gallery where (type = ? and wc = ? and fc = ? and yc = ? and sc = ?)"

You are not getting eloquent collection as a result. You are getting results as a string. Can you check what you get $images? Please use this in your controller: dd($images);

You have to change something. Because your $data is an array. But you have declare as an object. For this reason you get this error.

$data = $request->all();

$images = ImageGallery::where(['type'=>$data['type']],
    ['wc'=>$data['type']],
    ['fc'=>$data['fc']],
    ['yc'=>$data['yc']],
    ['sc'=>$data['sc']])->get();
