Question

我想检查数据库中的值是否与表单值相同。如何使用dd syntex查看数据库中的值？

dd('status');

$updateForm = Form::where('reference_no',$r->refer)
    -> update([
    'status' => $r->sts,
    'reference_no' => $r->refer,
    'task' => $r->tsk, 
    'receiver' => $r->to,
    'rider' => $r->frm,
  ]);

执行update时，它将返回受影响/更新的行数。它不会返回已更新的数据库行。

因此，您需要从数据库中获取数据并显示以下内容：

$numberOfRowsUpdated = Form::where('reference_no', $r->refer)
    -> update([
        'status' => $r->sts,
        'reference_no' => $r->refer,
        'task' => $r->tsk, 
        'receiver' => $r->to,
        'rider' => $r->frm,
    ]);

// This will get you the first form with given "reference_no"
$updatedForm = Form::where('reference_no', $r->refer)->first();
dd($updatedForm->status);

// If you are updating multiple rows and dump all its items and attributes
$updatedForms = Form::where('reference_no', $r->refer)->get();
dd($updatedForms);

也许这会有所帮助，您可以从这里继续。
