php - Twig Assignment operator -
i want calculate total numbers specific field in twig
in php template, can make so
<?php $tl = 0; ?> <?php foreach($loo $l):> <?php $tl += $l['amount'] ?> <tr> <td><?php echo $l['amount'] ?> </tr> <?php endforeach ?> <p><?php echo number_format($tl,2) ?> how in twig?
i tried
{% set tl = 0 %} {% task in tasks %} {% set tl += {{ task.amount }} %} {% endfor %} {{ tl }} it doesn't work ideas?
looks twig doesn't support combined operators php do. (i not find example in http://twig.sensiolabs.org/doc/templates.html#setting-variables)
maybe relevant: how make addition 2 variable twig?
could use try separate operator version?
{% set tl = tl + task.amount %}
