我的网站上有这个部分：[1]：https ://imgur.com/a/xJjb1ww "section"

我想限制这张照片显示最大值。4 个联系人，因为如果我有更多，它看起来很糟糕。我怎样才能添加到这个最大值。限制显示？对不起这么多代码，但我不知道我的功能到底在哪里。谢谢。

这是我的看法：

<!-- Tabs Widget -->


<div class="tab-content" style="padding: 8px !important">
                <?php $count_user = 0; ?>

                @foreach($user->contact as $contact)
                    <div id="contact<?php echo $count_user++; ?>" class="tab-pane magazine-sb-categories <?php if($count_user == 1){ echo "active"; } ?>">
                        <div class="row team-v1">


                        <ul class="list-unstyled col-xs-12" style="margin-bottom: -10px">
                    <li><h3 style="margin-top: 5px !important;text-transform: none; " >
                        @if($contact->role[0]->slug == "individuals")
                                        <i style="font-size: 13px;" class="icon-user"></i>

                                    @elseif($contact->role[0]->slug =='organizations')
                                        <i style="font-size: 13px;" class="icon-hotel-restaurant-172 u-line-icon-pro fa- fa-lg"></i>
                                    @endif

                                    <a style="font-size: 14px" href="{{ url('') }}/{{ $contact->username }}">{{ $contact->username  }}</a></h3>
                                <p>
                    <strong><i class="icon-real-estate-020 u-line-icon-pro"></i> : </strong><a>{{ $contact->country->country }}</a><br>
                    <strong><i class="icon-screen-tablet fa-" aria-hidden="true"></i> : </strong><a>{{ $contact->industry->industry }}</a><br>
                    @if($contact->role[0]->slug == "individuals")
                                                    @foreach($contact->career_path as $career_path)
                                                        <i style="font-size: 13px" class="icon-speedometer"></i> : {{ $career_path->functions->function }}
                                                        @break;
                                                    @endforeach
                                                @elseif($contact->role[0]->slug =='organizations')

                                                    <i style="font-size: 13px" class="icon-frame fa-"></i> : {{ $user->organization_type->organization_type }}<br>
                                                @endif


                        </p>
                    </ul>



                        </div>
@endforeach

这是我的 User.php：

public function contact() 
{ 
return $this->belongsToMany('App\User','contacts','contact_id','user_id')->limit(4); 
}

这应该在 User.php 中完成。

如果您为（即 hasMany）设置了关系$user->contact，您应该可以在刀片文件的循环中这样调用它：

$limitedContacts = $user->contact->limit(4);

@foreach($limitedContacts as $contact)
     ....
@endforeach
