Laravel 5.2-显示数据库中的第一个图像 [英] Laravel 5.2 - show first image from database

问题描述

我的数据库中有存储图像的表photos.在一个视图中，用户可以看到所有图像，但在另一个视图中，我只希望看到一个图像，第一个.如何设置它以便仅显示第一张图像，而不是全部显示?

I have table photos in my database where my images are stored. In one view user can see all of them, but in the other I want only one image to be seen, first one. How to set it so only the first image is displayed, not all of them?

这是我的代码.

查看

@foreach($business->photos as $photo)

    <img src="{{ url($photo->thumbnail_path) }}" class="img-thumbnail">

@endforeach

ProfileController

public function profile($id)
{
  $user = User::findOrFail($id);

  return view('business.profile', compact('user'));
}

Photo.php

public function business()
{
    return $this->belongsTo('App\Business');
}


public function baseDir()
{
    return 'images/';
}

public function setNameAttribute($name)
{
    $this->attributes['name'] = $name;

    $this->path = $this->baseDir() . '/' . $name;

    $this->thumbnail_path = $this->baseDir() . '/tn' . $name;
}

PhotosController

public function store($id, AddPhotoRequest $request)
{
  $business = Business::fidOrFail($id);

  $photo = $request->file('photo');

  (new AddPhotoToBusiness($business, $photo))->save();
}

推荐答案

解决方案:

@if(count($business->photos))
    <img src="{{ url($business->photos[0]->thumbnail_path) }}" class="img-thumbnail" alt="">
@else
    <img src="{{ URL::asset('/img/no-image.png') }}" class="img-responsive" alt="">
@endif
