Question

我已经与很多人建立了联系。下面的代码解释了我的所作所为。我已经在多选组合框中检索了干预区域，现在我试图将它们插入到数据库中。当我尝试选择多个区域时，会显示错误消息（在标题中）。如果有人可以帮助我，我将不胜感激。

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class technicien extends Model

    public function zoneintervention()

}

public function tarificationtache()

有很多关系，你不能这样做：

$technicien->zoneintervention_id= $request->input('zoneintervention_id');

使用attach()方法将对象附加到其他对象：

$technicien = new technicien();
$technicien->actif = $request->input('actif');
$technicien->moyenne_avis = $request->input('moyenne_avis');
$technicien->save();

$technicien->zoneintervention()->attach($request->zoneintervention_id);

return redirect('technicien');
