Hi, could you help me to organise the csv export correctly

I have a big report and would like to export a part of it. I created a separate class report file for that stock_list_csv.php and the export report file csv_export.php So from my main report i call csv_export.php via the form where with the post method i send the report parameters

The csv_export.php

<?php

require_once "stock_list_csv.php";

$report = new stock_list_csv;
//var_dump($_POST);
$report->run()->exportToCSV(array(
        "dataStores" => array(
            "stock_fact_names" => array(
                "delimiter" => ",",
            )
        )
))->toBrowser("myreport.csv");

As you can see I use var_dump to check how my form from the main file send the parameters and it looks ok.

/csv_export.php:8:
array (size=2)
  'barmode' => string '1' (length=1)
  'update_date' => string '62' (length=2)

The stock_list_csv.php

<?php
require_once "../../koolreport/core/autoload.php";

class stock_list_csv extends \koolreport\KoolReport
{
    use \koolreport\inputs\Bindable;
    use \koolreport\inputs\POSTBinding;
    use \koolreport\excel\CSVExportable;

    
    function settings()
    {
        $config = include "../../config.php";
        return array(
            "dataSources" => array(
                "quinos" => $config["quinos"],
            )
        );
    }

    function setup()
    {
        $query_fact = 'SELECT 
          item_id as id_f
        , quantity
        FROM mytbl_actual_stock 
        WHERE date_id in(:date_id) AND stock in(:stock)';


        $this->src("quinos")
            ->query($query_fact)
            ->params(array(
                ":date_id" => $this->params["update_date"],
                ":stock" => (($this->params["barmode"]==1) ? array(3) : array(2)),
            ))
            ->pipe($this->dataStore("stock_fact_names"));
    }
}

But as result I'm gettingt the empty table... so it looks like my stock_list_csv.php does not have access to the parameters from the main file and csv_export.php. if i set ":date_id" and ":stock" manually the report works... Where is my mistake?

I thought it happens automatically :-) because i use the POSTBinding...

Also the report works if i add

protected function bindParamsToInputs()
    {
        return array(
            "update_date" => "update_date",
            "barmode"=>"barmode",
        );
    }

to stock_list_csv.php - (I've found it a minute ago)

And one more question... Is it possible to not include the columns names to the csv file?

Unfortunately I need to import it to another application where I don't have a control under the import process and this app expected only data and no names of columns. It is not so difficult for me to delete the first row in a text editor but if I could get the file without name it were better :-) but if you don't have this option it is ok - koolreport has so many other more significant options that this small thing is not so important fo me :-)

Thank you

Thank you... :-)

Or like this :

$includeTitles = Util::get($option, 'includeTitles', true);
            if($includeTitles){
                $content .= implode($delimiter, $expColLabels) . "\n";
            } else {
                $content = "";
            }
