具有各自标题的自定义 foreach

Question

我有循环在这里查看图片以供参考..

我有名为供应商名称的列

例如有两行同一个供应商名称

所以我需要一个标题

我的预期输出是

ABS 机构

供应商名称 - 这里应该是标题

• ABS 机构 - 标题
  1. ABS 机构
  2. ABS 机构

我的代码在这里

   @foreach($prsdkgrids as $prsdkgrid)
                 <?php if($prsdkgrid->SupplierName == $prsdkgrid->SupplierName){ $SupplierName[] = $prsdkgrid->SupplierName; } ?>
                 @endforeach    

@foreach($prsdkgrids as $prsdkgrid)
                 <?php  if(count($SupplierName) == $SupplierName[$f]) { }else{  echo $f."<tr><td><h3 style='font-size: 15px;'>$prsdkgrid->SupplierName</h3></td></tr>"; } ?>
                 <tr class="psr_table1_tr" id="PSupdetID<?php echo $prsdkgrid->PSupdetID; ?>" <?php if($prsdkgrid->ApprovalStatus == 1){ echo 'style="background: #d9edf7;"';} ?>  >
                 <td> {{ Form::label('', $prsdkgrid->ArticleNo) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->Size) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->SpecialDesc) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->QtyExp) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->Coloring) }} </td>

                 <td> {{ Form::label('', $prsdkgrid->TargetPrice) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->SupPrice) }} </td>
                 <td> {{ Form::label('', $prsdkgrid->SupplierName) }}</td>

                 </tr> <?php $f++; ?>
                 @endforeach

您可以将供应商名称存储在一个变量中，并且在循环中您可以只比较变量和供应商名称。一个简单的方法是这样的，因为您使用的是foreach()

$tmp_supplier_name = '';

foreach($prsdkgrids as $prsdkgrid){

  echo ($tmp_supplier_name != $prsdkgrid->supplier_name) ? '<tr>SUppliername</tr>' : ''; //compare

  $tmp_supplier_name = $prsdkgrid->supplier_name; //store the suppliername that was compared

}

或者另一种方法是尝试操作你的数组，它应该是这样的，可读性很强。

Array(
  ['supplierA'] =>
          Array(
             [0] => array(.....)
             [1] => array(.....)
          ),
  ['supplierB'] =>
         Array(
             [0] => array(.....)
             [1] => array(.....)
          )
) 

重新创建数组示例：

    $new_array = [];
    $tmp_supplier_name = '';

foreach($prsdkgrids as $prsdkgrid){

    if($tmp_supplier_name  != $prsdkgrid->supplier_name){
      $tmp_supplier_name = $prsdkgrid->supplier_name;
    }else{
      $new_array[$prsdkgrid->supplier_name]['opt1'] = $prsdkgrid->opt1;
      $new_array[$prsdkgrid->supplier_name]['opt2'] = $prsdkgrid->opt2;
      //and so on
    }
}
