這是一個角色和權限表，到目前為止我可以更改用戶的角色，但洗掉用戶。
如何進行更改角色和洗掉操作？
<form action="edit-role-permission/{{ $user->id }}" method="POST">
@csrf
<select name="roles">
<option name ="user" value="user">User</option>
<option name= "staff" value="staff">Staff</option>
</select>
<button type="submit">Change role</button>
<button type="submit">Delete</button>
</form>
Route::post('edit-role-permission/{user}', [AdminController::class, 'editRolePermission']);
//class AdminController extends Controller
function editRolePermission(Request $request, User $user)
{
$user->update(["role" => $request->roles]);
$user->save();
return redirect()->back()->with("message", "User role updated successfully");
}
uj5u.com熱心網友回復：
添加按鈕的名稱name="action"和values：
<button type="submit" name="action" value="update">Change role</button>
<button type="submit" name="action" value="delete">Delete</button>
并檢查它：
if ($request->input('action') == "update") {
// update here
} else if ($request->input('action') == "delete") {
// delete here
}
