Get Id Field From Eloquent Laravel-CodePudding

I want get id value from eloquent laravel and passing to variable to insert process. this is my eloquent to get data from siswa table

$siswa = Siswa::where('nis', $row['nis'])->first();

but when accessing id value like $siswa->id I'm getting error enter image description here

CodePudding user response：

Use this code

if($siswa){
 $id=$siswa->id;
}

CodePudding user response：

$siswa variable can be null. Look at its contents with the dd($siswa) command.

To escape the error you can use it like this:

if($siswa)
{
 // $siswa not null.
}

CodePudding user response：

=>first you can $id pass on your public function like
  
public function show($id)
{
    $siswa = Siswa::where('id', $id)->first();
 }
=>you can pass your id on your route
