【中文标题】是否有任何功能可以停止 foreach 循环? [复制]【英文标题】:Is there any function to stop foreach loop? [duplicate] 【发布时间】:2019-11-03 09:56:18 【问题描述】:每当我尝试使用类别名称打印表格第一行打印良好,然后使用 ONE tr(row) 数据打印表格并关闭标签并再次开始新行并打印下一个数据时,我都会设置一个循环一排……
我想打印关于其类别名称的所有数据而不破坏多个表
@if( ! empty($packages) )
@php
$serviceId=null;
@endphp
@foreach($packages as $package)
@if(is_null($serviceId))
<!--CATEGORY NAME PRINT-->
<div class="row" id="">
<div class="col-sm-12">
<div class="well wellHeader">
<h2> $package->service->name </h2>
</div>
</div>
</div>
<!--CATEGORY NAME PRINT-->
@php
$serviceId=$package->service->id
@endphp
@endif
@if($serviceId != $package->service_id)
<!--CATEGORY NAME PRINT-->
<div class="row" id="">
<div class="col-sm-12">
<div class="well wellHeader">
<h2> $package->service->name </h2>
</div>
</div>
</div>
<!--CATEGORY NAME PRINT-->
@php
$serviceId = $package->service_id
@endphp
@endif
<!--SERVICE NAME TABLE-->
<div class="row">
<div class="col-sm-12">
<div class="well">
<div class="table-responsive">
<table class="table table-striped table-sm ">
<thead>
<tr>
<th>@lang('general.package_id')</th>
<th>@lang('general.name')</th>
<th>@lang('general.price_per_item') getOption('display_price_per') </th>
<th>@lang('general.minimum_quantity')</th>
<th>@lang('general.maximum_quantity')</th>
<th>@lang('general.description')</th>
</tr>
</thead>
<tbody>
<tr>
<td> $package->id </td>
<td> $package->name </td>
<td>@php $price = isset($userPackagePrices[$package->id]) ? $userPackagePrices[$package->id] : $package->price_per_item;
@endphp
getOption('currency_symbol') . number_formats(($price * getOption('display_price_per')),2, getOption('currency_separator'), '') </td>
<td> $package->minimum_quantity </td>
<td> $package->maximum_quantity </td>
<td> $package->description </td>

【问题讨论】:
等等,这不是关于 javascript 的……你为什么在它不相关的时候标记它? 我的表被分成多个检查截图 见break
,可能还有continue
见***.com/questions/45189524/…
【参考方案1】:
您可以创建一个额外的数组来映射它,
在方法中
$packagesNew = [];
foreach($packages as $k => $v)
$packagesNew[$v->service->name]['name'] = $v->service->name;
$packagesNew[$v->service->name]['id'] = $v->service->id;
$packagesNew[$v->service->name]['service_id'] = $v->service_id;
$packagesNew[$v->service->name]['data'][] = $v;
通过packagesNew
查看
然后我在视图中进行了更改,请检查。
@if( ! empty($packagesNew) )
@php
$serviceId=null;
@endphp
@foreach($packagesNew as $k => $package)
@if(is_null($serviceId))
<!--CATEGORY NAME PRINT-->
<div class="row" id="">
<div class="col-sm-12">
<div class="well wellHeader">
<h2> $k </h2>
</div>
</div>
</div>
<!--CATEGORY NAME PRINT-->
@php
$serviceId=$package['id'];
@endphp
@endif
@if($serviceId != $package['service_id'])
<!--CATEGORY NAME PRINT-->
<div class="row" id="">
<div class="col-sm-12">
<div class="well wellHeader">
<h2> $k </h2>
</div>
</div>
</div>
<!--CATEGORY NAME PRINT-->
@php
$serviceId = $package['service_id'];
@endphp
@endif
<!--SERVICE NAME TABLE-->

【讨论】:
你的意思是在模型中创建这个方法吗? 您知道,您可能正在模型或控制器中创建包。那里你需要写这段代码 模型和控制器中的代码是用 ioncube 加密的:\有什么办法吗? 试着写在你感觉的地方;) ok 让我试试 :)以上是关于是否有任何功能可以停止 foreach 循环? [复制]的主要内容,如果未能解决你的问题,请参考以下文章
