Please how can i send dynamic values to database in laravel using eloquent

Please can anyone assist in sending this dynamic values to database in laravel..I have tried the method i know, but i am not sure why i am not able to send it to the database

//This is the view

  @foreach ($request as $item)
                            <tbody>
                              <tr>
                              <td  class="idweek1"> <input type="text" id="idweek1" name="idweek1" class="form-control" value=""> </td>
                              <td><input type="text" id="marketers" name="marketers" class="form-control" value="">  </td>
                              <td><input type="text" id="amount" class="form-control" value=""> </td>
                              <!-- <td></td> -->
                              <td id="fundsforall" name="fundsforall" class="fundsforall"><input type="text" id="mar1id" class="form-control" value="">   </td> 
                              </tr>
                            </tbody>

                            @endforeach

I have tried to use a for each loop to send but it returns a message that Invalid argument supplied for foreach()

Below is the foreach loop i have tried

//This is the loop in the controller..i am using a Post route

foreach ($request->idweek1 as $key => $value){

           $str_explode = explode("|",$value);


           $insert[] = [
                'user_id' => $str_explode[1],
                'amount'  => $request->amount[$key]

              ];



      }
