从动态创建的输入字段将数据更新到表中 [英] Update data into table from dynamically created input field

问题描述

我有2个模型 Tour.php

public function Itinerary()
{
    return $this->hasMany('App\Itinerary', 'tour_id');
}

和

Itinerary.php

public function tour() 
{
    return $this->belongsTo('App\Tour', 'tour_id');
}

游览表:

id|title|content

入门表:

id|tour_id|day|itinerary

我已经使用vue js创建或添加和删除了一天的输入字段，并进行了动态计划.并在tour.store方法中使用以下代码插入到itineraries表中:

I have used vue js to create or add and remove input field for day and plan dynamically. And used the following code in tour.store method to insert into itineraries table:

    $count = count($request->input('day'));
$temp_day        = $request->input('day');
$temp_itinerary  =   $request->input('itinerary');

for($i = 0; $i < $count; ++$i) 
{

    $itinerary = new Itinerary;
    $itinerary->tour_id        =  $tour->id;
    $itinerary->plan      =   $temp_itinerary[$i];        
    $itinerary->day            =   $temp_day[$i];
    $itinerary->save();
}

成功插入记录.并在tour.store方法中应用了相同的代码.它没有更新行，而是向表中插入了新行.最好的解决方案是什么?

And was successful in inserting the records.And applied same code in tour.store method. Instead of updating the rows, it inserted new rows to the table. What would be the best solution for this ?

推荐答案

要进行更新，请尝试以下代码

For updation try this code

$itinerary = Itinerary::find($tour_id);
$itinerary->plan = $temp_itinerary[$i];        
$itinerary->day = $temp_day[$i];
$itinerary->save();
