{!! csrf_field() !!}
<div class="col-md-5">
<strong>TYPE</strong>
<select name="type" class="form-control">
<option value="" selected>Please Select</option>
<option value="j">j</option>
<option value="w">w</option>
</select>
</div>
<div class="col-md-5">
<strong>wc</strong>
<select name="wc" class="form-control">
<option value="" selected>Please Select</option>
<option value="N0">0</option>
<option value="N1">1</option>
<option value="N2">2</option>

<div class="col-md-5">
<strong>YC</strong>
<select name="yc" class="form-control">
<option value="" selected>Please Select</option>
<option value="yc1">yc1</option>
<option value="yc2">yc2</option>
</select>
</div>
<div class="col-md-5">
<strong>SC</strong>
<select name="sc" class="form-control">
<option value="" selected>Please Select</option>
<option value="Z01">Z01</option>
<option value="Z02">Z02</option>
<option value="Z03">Z03</option>
</select>
</div>
<div class="col-md-2">
<br/>
<button type="submit" class="btn btn-success">Search</button>
</div>
</form>
result.blade.php
<div class='list-group gallery'>
#if($images->count())
#foreach($images as $image)
<div class='col-sm-4 col-xs-6 col-md-3 col-lg-3'>
<a class="thumbnail fancybox" rel="ligthbox" href="/images/{{ $image->image }}">
<img class="img-responsive" alt="" src="/images/{{ $image->image }}" />

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');

Answer 2

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');

Answer 3

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();
