I have a view in which I display two data that I take from a table of a DB and next to these data I have two buttons that take me to the same view in which I need to display other things. What I can't figure out is, how do I differentiate the view AFTER pressing the button? Here there are the images of the two view: https://imgur.com/a/i5BcPaw

The code is the following:

Controller:

<?php

namespace App\Http\Controllers;

use App\Models\Device;
use App\Models\DataFromRasp;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Symfony\Component\Process\Process;
use Symfony\Component\Process\Exception\ProcessFailedException;

class DeviceController extends Controller
{
    public function index()
    {
        $data=Device::all();
        return view('backend.auth.user.device', compact("data"));

    }

    public function create()
    {
        
    }

    public function store(Request $request)
    {
        
    }

    public function show(Device $deviceID)
    {
        
    }

    public function edit(Device $device)
    {
        //
    }

    public function update(Request $request, Device $device)
    {
        //
    }

    public function destroy(Device $device)
    {
        //
    }

    /**
     * Displays all data present in the table data_from_rasps
     * 
     * The data are all the devices that the raspberry can capture 
     */
    public function visualizeData() 
    {
        $data=DataFromRasp::paginate(10);
        return view('backend.auth.user.dictionary', compact("data"));
    }

    /**
     * Raspberry capture and send the data to the DB and save in another
     * table of the same DB the MAC addresses of interest
     */
    public function getData(Request $request)
    {   
        $m_data = $request->get('m_data');
        $r_data = $request->get('r_data');
        DataFromRasp::create(['MAC' => $m_data, 'RSSI' => $r_data]);
        if(($m_data == 'C4:A5:DF:24:05:7E') and Device::where('MAC_ADDR', $request->m_data)->doesntExist()){ 
            Device::create(['USERNAME'=>'Device1','MAC_ADDR' => $m_data]);
        }
        if(($m_data == '70:1C:E7:E4:71:DA') and Device::where('MAC_ADDR', $request->m_data)->doesntExist()){ 
            Device::create(['USERNAME' => 'Device2','MAC_ADDR' => $m_data]);
        }
    }

    public function scan()
    {
        $process = new Process(['C:\Simone\Università\Tirocinio\laravel-boilerplate-master', 'prova.py']);
        $process->run();
        if (!$process->isSuccessful()) { throw new ProcessFailedException($process); }
        return redirect()->route('dict');
    }

    public function singleDev(Device $deviceID){
        $data = DataFromRasp::select('RSSI', 'created_at')->where('MAC', 'C4:A5:DF:24:05:7E')->get();
        $time_array = [];
        $rssi_array = [];
        $cnt = 0;
        foreach($data as $dataItem){
            array_push($time_array, $dataItem->created_at->format('H:i:s'));
            array_push($rssi_array, $dataItem->RSSI);
        }

        return view('backend.auth.user.singleDevice', compact("time_array", "rssi_array"));
    }
}

View where I select the device:

@extends('backend.layouts.app')

@section('content')

<table >
  <thead>
    <tr>
      <th scope="col">ID</th>
      <th scope="col">USERNAME</th>
      <th scope="col">MAC ADDRESS</th>
    </tr>
  </thead>
  <tbody>
    @foreach ($data as $item)
    <tr>
      <th scope="row">{{$item->id}}</th>
      <td>{{$item->USERNAME}}</td>
      <td>{{$item->MAC_ADDR}}</td>
      <td>
         <a href="{{ url('admin/singleDevice/'.$item->id) }}" >Select</a>
      </td>
    </tr>
    @endforeach
  </tbody>
</table>
@endsection

Does anyone know how to do this? Thanks in advance

CodePudding user response：

Try to use this code

<a href="/admin/singleDevice/{{ $item->id }}" >Select</a>

Instead of

 <a href="{{ url('admin/singleDevice/'.$item->id) }}" >Select</a>

Updated!

I a little bit didn't get what you trying to achieve, but why didnt your try to add another button next to it, to show another view?

CodePudding user response：

You could create an if statement to determine if one of the buttons is pressed whenever you load the page.

In blade

<button type="submit" name="device_id" value="$item->id">Select</button>

In controller

$data=Device::all();
$singleDevice = Device::where('id', '=', Input::get('device_id'))->first();
if($singleDevice === null)
{
  return view('backend.auth.user.device', compact("data"));
}
else
{
        $time_array = [];
        $rssi_array = [];
        $cnt = 0;
        foreach($singleDevice as $dataItem){
            array_push($time_array, $dataItem->created_at->format('H:i:s'));
            array_push($rssi_array, $dataItem->RSSI);
        }

        return view('backend.auth.user.singleDevice', compact("time_array", "rssi_array"));
}
