php - Class 'CHtml' not found in Gridview in Yii2 -


i developing yii2 application want list orders data in gridview.

user can click on order id , redirected gridview order details listing. want display link order id redirect order details page.

but got following error:

class 'chtml' not found

in gridview. here code:

<?= gridview::widget([     'dataprovider' => $dataprovider,     'filtermodel' => $searchmodel,     'columns' => [          ['class' => 'yii\grid\serialcolumn'],          [              'attribute'  => 'id',              'value' => chtml::link("link", yii::app()->createurl("user/view")),              'format'  => 'raw',          ],          'user_id',          'amount',          'promo_code_used',             ['class' => 'yii\grid\actioncolumn'],     ], ]) ?>

thers no chtml in yii2. use html helper instead (see docs here , here). generating hyperlink use html::a() instead of chtml::link(). code this:

use yii\helpers\html;      ...  echo html::a("link", ["user/view"]);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
