Sometime you may want to simplify your data flow by removing some of columns from the datapipe. You can do so with RemoveColumn process. This process will act like a filter which only let other columns except for the columns specified passing through.
Sample code
->pipe(new RemoveColumn(array(
"age", "income"
)))
<?php
require_once "MyReport.php";
$report = new MyReport;
$report->run()->render();
<?php
//Step 1: Load KoolReport
require_once "../../../load.koolreport.php";
use koolreport\processes\RemoveColumn;
//Step 2: Creating Report class
class MyReport extends \koolreport\KoolReport
{
protected function settings()
{
return array(
"dataSources"=>array(
"data"=>array(
"class"=>'\koolreport\datasources\ArrayDataSource',
"dataFormat"=>"table",
"data"=>array(
array("name","income","age"),
array("John",50000,25),
array("Marry",60000,30),
array("Peter",100000,45),
array("Donald",80000,40),
)
)
)
);
}
protected function setup()
{
//Prepare data
$this->src("data")
->pipe($this->dataStore("origin"));
//Pipe through process to get result
$this->src("data")
->pipe(new RemoveColumn(array(
"age", "income"
)))
->pipe($this->dataStore("result"));
}
}
