Laravel5.0: passing value from a controller method to a .php file in public folder

Question

I want to pass a value from my controller to a .php file which is inside public folder. This is my controller part

<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class DashboardController extends Controller {

public function barChart(){

    $barChart= DB::table('clients')
        ->select('clients.ClientName','clients.Price')
        ->get();
    //want to pass this $barChart variable
}

Location of .php file is

/dist/chart/clients.php

I want to have this $barChart variable in clients.php file and perform further operation.

update 1: this is the view part

    <div class="panel-body" id="barChart">

    </div>



    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

    <script type="text/javascript">
        $(document).ready(function() {
        $.ajax({
        //url: "{{URL::asset('/dist/chart/clients.txt')}}", //this works, I saved the json_encode($bar) at client.txt file
        data: [{{$bar}}], //this does not work
        dataType:"JSON",
        success: function(result){
            google.charts.load('current',{
            'packages':['corechart']
            });
            google.charts.setOnLoadCallback(function(){
            drawChart(result);
            });
        }
        });

        function drawChart(result) {server.
            var data = new google.visualization.DataTable();
            data.addColumn('string' , 'ClientName');
            data.addColumn('number', 'Price');
            var dataArray=[];
            $.each(result, function(i, obj){
            dataArray.push([obj.ClientName, parseInt(obj.Price)]);
        });
        data.addRows(dataArray);

            var barChart_options = {
            title: 'hoise??',
            is3D: 'true',
            width: 400,
            height: 300
        };
        var barChart = new google.visualization.BarChart(document.getElementById('barChart'));
                    barChart.draw(data, barChart_options);
        }
});


</script>

update 2

controller update

<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Carbon\Carbon;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class DashboardController extends Controller {


public function index()
{

    try{
        $val=DB::connection()->getDatabaseName();
        if(DB::connection()->getDatabaseName()) {

            $barChart= DB::table('clients')
                ->select('clients.ClientName','clients.Price')
                ->get();
            $bar = json_encode($barChart);

            return view('home')
                ->with('bar', $bar);

        }else{
            $er="/connection status: database error";
            return view('errors/503')->with('error',$er);
        }
    }catch (\Exception $e){
        $er="/connection status: database error";
        return view('errors/503')->with('error',$er);
    }

}

public function barChart(){

    $barChart= DB::table('clients')
        ->select('clients.ClientName','clients.Price')
        ->get();
    echo json_encode($barChart);
}
public function create()
{
    //
}
public function store()
{
    //
}
public function show($id)
{
    //
}
public function edit($id)
{
    //
}
public function update($id)
{
    //
}
public function destroy($id)
{
    //
}
}

Instead create a blade file and simply access the values over there. — Narendrasingh Sisodia

inside my view I want to use that $barChart variable json_encoded. $.ajax({ url: "{{URL::asset('/dist/chart/clients.php')}}", dataType:"JSON", success: function(result){ google.charts.load('current',{ 'packages':['corechart'] }); — Erfan Ahmed

Add your clients.php to resources/views directory and name it clients.blade.php, it will work the same but give you a nice templating engine.

In your controller/barChart method do this.

$barChart= DB::table('clients')
    ->select('clients.ClientName','clients.Price')
    ->get();
return view('clients', compact('barChart'));

In the view file resources/views/clients.blade.php you can now access the $barChart variable.

You can use it in your view like this:

{{ json_encode($barChart) }}

or if you are not using Blade, then

<?= json_encode($barChart) ?>

but, I can't use $barChart as an url inside $.ajax({url: }) . The very reason I asked this question so that I can use the output of json_encode($barChart) , inside $.ajax({url: ..here... }) in my view. Integrating google chart is made me do this. If you know a better way to integrate google chart with laravel with the value from mysql database please tell me.

Mubashar Abbas Over a year ago

you need to send it as data property of ajax right?

Erfan Ahmed Over a year ago

Thanks for your effort but it didn't work for me. I updated my question. please look at it. It might help you to understand my problem clearly.

Mubashar Abbas Over a year ago

in my answer I mentioned putting your clients.php file in resources/views. Did you do that?

Put your clients.php to resenter code hereources/views directory and name it clients.blade.php

Change your controller like

<?php 
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class DashboardController extends Controller {
public function barChart(){
$barChart=DB::table('clients')
->select('clients.ClientName','clients.Price')-  >get();
return view('clients')->with('barChart' => $barChart);
}
?>

Well finally I came up with the solution. I can't pass variable to public folder and giving the ulr in ajax was also a problem in that case creating the data table is obvous then pass it. the controller part will be

public function index()
{
    try{
        $val=DB::connection()->getDatabaseName();
        if(DB::connection()->getDatabaseName()) {

            $barChart= DB::table('clients')
                ->select('clients.ClientName','clients.Price')
                ->get();

            $rows = array();
            //flag is not needed
            $flag = true;
            $table = array();
            $table['cols'] = array(
                array('label' => 'Weekly Task', 'type' => 'string'),
                array('label' => 'Percentage', 'type' => 'number')

            );

            $rows = array();
            foreach($barChart as $r) {
                $temp = array();
                $temp[] = array('v' => (String)$r->ClientName);
                $temp[] = array('v' =>(int)$r->Price);
                $rows[] = array('c' => $temp);
            }

            $table['rows'] = $rows;
            $bar = json_encode($table);





            return view('home')
                ->with('bar', $bar);

        }else{
        }
    }catch (\Exception $e){
    }

}

The view part will be

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
                    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
                    <script type="text/javascript">

                        // Load the Visualization API and the piechart package.
                        google.load('visualization', '1', {'packages':['corechart']});

                        // Set a callback to run when the Google Visualization API is loaded.
                        google.setOnLoadCallback(drawChart);

                        function drawChart() {

                            // Create our data table out of JSON data loaded from server.
                            var data = new google.visualization.DataTable(<?=$bar?>);
                            var options = {
                                title: 'My Chart',
                                is3D: 'true',
                                width: 400,
                                height: 300
                            };
                            // Instantiate and draw our chart, passing in some options.
                            // Do not forget to check your div ID
                            var chart = new google.visualization.BarChart(document.getElementById('barChart'));
                            chart.draw(data, options);
                        }
                    </script>
