Hi!
Im new to Yii2.0 and I have a problem figuring out how to display a subtotal row in Gridview. I hope somebody can help me. I know there is this renderRowTable but I do not know how to use it. can somebody help me by providing some sample code?
Attached is the end result of the screen that i want to do.
i give just hint…
use 2amigos/yii2-gridview and in GroupGridView class that just edit renderExtraRow function
protected function renderExtraRow($model, $key, $index, $totals)
{
if ($this->extraRowValue instanceof Closure) {
$content = call_user_func($this->extraRowValue, $model, $index, $totals);
} else {
$values = [];
foreach ($this->extraRowColumns as $name) {
$values[] = ArrayHelper::getValue($model, $name);
}
$content = '<strong>' . implode(' :: ', $values) . '</strong>';
}
$colspan = count($this->columns);
/* add following */
$cell = Html::tag('td', 'Sub Total', ['class' => $this->extraRowClass, 'colspan' => $colspan]);
/*****************/
$cell = Html::tag('td', $content, ['class' => $this->extraRowClass, 'colspan' => $colspan]);
return Html::tag('tr', $cell);
}
than for subtotal use this in grid view:
'extraRowTotalsValue' => function($data, $row, &$totals) {
/* this is example function make yours subtotal attribute...*/
if(!isset($totals['sum_credit'])) $totals['sum_credit'] = 0;
$totals['sum_credit'] += $data['relSubject']['credits'];
},
after configure Grid view extra row setting as per your requirements…
Also you can subclass GridView widget and override renderFooter method.
