如何在laravel 5.6刀片中获取计数值？

Question

I want to show the count according to rta_id and deleted_at..I have rta_id and deleted_at column in issuer table.

<?php 
    $issuer = DB::table('issuer')
                ->where(['rta_id'=> $rtaData->rta_id])
                ->get(); 
?>
    <td style="text-align: center;">
        <a href="{{ url('/admin/view-issuer/'.$rtaData->rta_id ) }}" class="btn btn-primary btn-mini" >
            {{ count($issuer) }}
    </td>

This is my code. i have displayed the count value according to rta_id but i also want to show count value according to deleted_at when it is null means only count the rows where the deleted_at is equals to NULL.

Please help to count the rows according ton rta_id and deleted_at value in the same query....

Answer 1

In controller get those records having deleted_at = null like shown below and send to view.

$issuer= DB::table('issuer')->where(['rta_id'=> $rtaData->rta_id])->where('deleted_at',null)->get();

then in blade view

{{count($issuer)}}

Answer 2

Use Count eloquent

$count = DB::table('issuer')
            ->where('rta_id', '=', $rtaData->rta_id)
            ->where('deleted_at', '=', null)
            ->count(); 

And you need to add this lines in your controller and then send it in your view using compact

In your blade

<td style="text-align: center;">
    <a href="{{ url('/admin/view-issuer/'.$rtaData->rta_id ) }}" class="btn btn-primary btn-mini" >
        {{ $issuer }} 
    </a>
</td>

Do it like this

<?php 
    $issuer = DB::table('issuer')
            ->where(['rta_id'=> $rtaData->rta_id])
            ->where('deleted_at', null)
            ->count(); 
?>
<td style="text-align: center;">
    <a href="{{ url('/admin/view-issuer/'.$rtaData->rta_id ) }}" class="btn btn-primary btn-mini" >
        {{ $issuer }}</a>
</td>
