Question

我的表单有一个选择框，我需要将选择框选择的值传递给laravel资源show()方法，以显示所选值的特定详细信息。

<form action="{{ action('supplierController@show') }}" method="POST" class="form" role="form">
  <div class="form-group">
      <label for="inputEmail3" control-label">company name</label>
      <select class="form-control js-example-basic-single" name="seller">
        <option value=""></option>
        @foreach($supplierlist as $supplier)
          <option value="{{ $supplier->company_name }}">{{ $supplier->company_name }}</option>
        @endforeach
      </select>
  </div>

  <input type="hidden" name="_token" value="{{ csrf_token() }}">
  <button type="submit" class="btn btn-primary">GO</button>
</form>

selectbox的值来自数据库，所以我如何将selectbox的选定值的值传递给我的控制器。

<div class="ui-grid ui-grid-responsive ui-fluid" *ngIf="saveObject"> <div *ngFor="let f of fields; let i = index"> <div *ngIf="i % 2 === 1 && i < fields?.length" class="ui-grid-row"> <div *ngFor="let field of [fields[i-1],fields[i]]"> <div class="ui-grid-col-3 field-label"><label for="attribute">{{field.key}}</label></div> <div class="ui-grid-col-3"> <p-checkbox *ngIf="booleanFields.indexOf(field.key) !== -1" binary="true" [(ngModel)]="saveObject[field.key]"></p-checkbox> <p-calendar *ngIf="dateFields.indexOf(field.key) !== -1" [(ngModel)]="saveObject[field.key]" dateFormat="yy-mm-dd" [showIcon]="true"></p-calendar> <input *ngIf="(booleanFields.indexOf(field.key) === -1) && (dateFields.indexOf(field.key) === -1)" pInputText id="attribute" [(ngModel)]="saveObject[field.key]"/> </div> </div> </div> <div *ngIf="fields?.length % 2 === 1 && i === fields?.length - 1"> <div *ngFor="let field of [fields[i]]"> <div class="ui-grid-col-6 field-label"><label for="attributeEnd">{{field.key}}</label></div> <div class="ui-grid-col-6"> <p-checkbox *ngIf="booleanFields.indexOf(field.key) !== -1" binary="true" [(ngModel)]="saveObject[field.key]"></p-checkbox> <p-calendar *ngIf="dateFields.indexOf(field.key) !== -1" [(ngModel)]="saveObject[field.key]" dateFormat="yy-mm-dd" [showIcon]="true"></p-calendar> <input *ngIf="(booleanFields.indexOf(field.key) === -1) && (dateFields.indexOf(field.key) === -1)" pInputText id="attributeEnd" [(ngModel)]="saveObject[field.key]"/> </div> </div> </div> </div> </div>应该有一个名称，然后您可以使用<select>获取值。

请尝试以下方法在您的视图中，部分包括以下内容，请考虑$ categories包含选项中的类别

{!! Form :: select（＆＃39; category＆＃39;，array（＆＃39; 0＆＃39; =＆gt;＆＃39;选择类别＆＃39;）+ $ categories，[＆＃39; class＆＃39; =＆gt;＆＃39;中m-wrap＆＃39;]）!!}

在您的控制器中包含

$category = $request->get('category');

在Laravel中将select视图的值传递给控制器
