问题描述
我正在尝试在 Laravel 中导入 Excel 数据并插入到数据库中。我正在使用 maatwebsite/excel 版本 3 composer 包。
错误:未定义索引:customer_name
<form method="post" enctype="multipart/form-data" action="{{ url('/import_excel/import') }}">
{{ csrf_field() }}
<div class="form-group">
<table class="table">
<tr>
<td width="40%" align="right"><label>Select File for Upload</label></td>
<td width="30">
<input type="file" name="select_file" />
</td>
<td width="30%" align="left">
<input type="submit" name="upload" class="btn btn-primary" value="Upload">
</td>
</tr>
<tr>
<td width="40%" align="right"></td>
<td width="30"><span class="text-muted">.xls,.xslx</span></td>
<td width="30%" align="left"></td>
</tr>
</table>
</div>
</form>
public function model(array $row)
{
$data = [];
foreach ($row as $value)
{
$data[] = array(
'CustomerName' => $row['customer_name'],'Gender' => $row['gender'],'Address' => $row['address'],'City' => $row['city'],'PostalCode' => $row['postal_cole'],'Country' => $row['country']
);
}
DB::table('customers')->insert($data);
}
控制器功能
public function import(Request $request)
{
$this->validate($request,[
'select_file' => 'required|mimes:xls,xlsx'
]);
$path = $request->file('select_file')->getRealPath();
Excel::import(new CustomerImport,$path);
return back()->with('success','Excel Data Imported successfully.');
}

有人可以指导我吗?
解决方法
要使用 heading row,您需要像这个例子一样实现 WithHeadingRow
namespace App\Imports;
use App\User;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
class UsersImport implements ToModel,WithHeadingRow
{
public function model(array $row)
{
return new User([
'name' => $row['name'],'email' => $row['email'],'at' => $row['at_field'],]);
}
}
