Laravel add dynamic input fields
提问by Muhammad Kazim
I want to insert dynamic fields into DB. I'm using the following code but it does not work as I expect.
我想将动态字段插入数据库。我正在使用以下代码，但它不像我预期的那样工作。
<html>
<input id="reporting" type="text" value="salman" name="reporting[]">
<input id="reporting" type="text" value="ankur" name="reporting[]">
</html>
<?php
$report = Input::get('reporting');
for($i=0; $i<=count($report);$i++)
{
$news = new Reporting();
$news->user_id = 1;
$news->reporting = $report;
$news->save();
}
?>
expected result:
预期结果：
user_id || reporting
1 Salman
1 Ankur

As $reportis an array, current item of it can be received with []notation:
作为$report一个数组，它的当前项可以用[]符号接收：
$report = Input::get('reporting');
for($i=0; $i<=count($report);$i++)
{
$news = new Reporting();
$news->user_id = 1;
$news->reporting = $report[$i]; // here add [$i]
$news->save();
}

You could map the collection and create a new report while storing value of reports the way you want:
您可以映射集合并创建新报告，同时以您想要的方式存储报告的值：
<html>
<body>
@if(session('success'))
<div class="alert alert-success">
{{ session('success') }}
</div>
@endif
<form action="/" method="post">
{{csrf_field()}}
<input id="reporting" type="text" value="salman" name="reporting[]">
<input id="reporting" type="text" value="ankur" name="reporting[]">
<button type ="submit"> Send </button>
</form>
</body>
</html>
Catch data on backend:
在后端捕获数据：
public function store()
{
$fields = collect(Input::get('reporting'));
$fields->map(function($value, $key){
return Reporting::create([
'user_id'=>1,
'reporting'=>$value,
]);
});
return redirect('/')->with('success', 'Action was successful');
}
This will produce the data in this format:
这将生成以下格式的数据：
user_id || reporting
1 Salman
1 Ankur
Note: Tested working correctly!
注意：经测试工作正常！
