how do i apply condition through the table values? - php

Question

I am making a carousel which should display the info dynamically in it. And here i am trying to apply condition through which the result can be filtered but it doesn't seems to be working. Below is the code for it.(what i really want to achieve through this is to appear the results in a carousel). Any kind of help would be immensely appreciated
<div class="container">
<div class="row" style="padding: 75px">
#if($tours->continent_id == 5)
<div class="row">
<div class="col-md-9">
<h3>Featured {{$tours->continent->name}}</h3>
</div>
<div class="col-md-3">
<!-- Controls -->
<div class="controls pull-right hidden-xs">
<a class="left fa fa-chevron-left btn btn-success"
href="#carousel-example"
data-slide="prev"></a><a class="right fa fa-
chevron-
right btn btn-success" href="#carousel-example"
data-slide="next"></a>
</div>
</div>
</div>
<div id="carousel-example" class="carousel slide hidden-xs" data-
ride="carousel">
<!-- Wrapper for slides -->
<div class="carousel-inner">
<div class="item active">
<div class="row">
#foreach($tours as $tour)
<div class="col-sm-3">
<div class="col-item">
<div class="photo">
<img src="{{$tour->photo->file ?
asset($tour->photo->file): asset('images/404.png')}}"
class="img-responsive" alt="a" />
</div>
<div class="info">
<div class="row">
<div class="price col-md-6">
<h5>{{$tour->location}}</h5>
<h5 class="price-text-
color">
{{$tour->service}}</h5>
</div>
<div class="rating hidden-sm
col-md-
6">
<i class="price-text-color
fa
fa-star"></i><i class="price-text-color fa fa-star">
</i><i class="price-text-color
fa
fa-star"></i><i class="price-text-color fa fa-star">
</i><i class="fa fa-star"></i>
</div>
</div>
<div class="separator clear-left">
<p class="btn-add"> <i class="fa fa-shopping-cart"></i>Add to cart
</p>
<p class="btn-details"> <i class="fa fa-list"></i>More details
</p>
</div>
<div class="clearfix">
</div>
</div>
</div>
</div>
#endforeach
</div>
</div>
#endif
</div>
</div>
Here is the controller part of the code. which is including all the fillable values in the form view. which later can be used to apply conditions on the form or return it's table values in the form
public function index()
{$tours = Tour::all();
return view('admin/tour/slider',compact('tours'));}

Answer 1

What you want is to filter the tours and only interact with the ones that contain continent_id equals to 5?
In that case, you should improve the query on database
$tours = Tour::where('continent_id', 5)->get();
Or filter the collection
$tours->filter(function ($tour) {
return $tour->continent_id == 5;
}
In both cases, you won't be able to do {{ $tours->continent->name }} since you're working with a Collection of Tour, not with a Tour instance.
In order to print the title of the first tour you should do
$tours->first()->continent->name

All i had to do was to put if condition after the foreach statement for its values to be available for the loop at before that foreach loop i had to check for the existence of the values in the table like #if($tours). and it all worked nicely :)
