The issue is, that you are constructing the data
property of the $row[]
as string
and not as an array
. See below, how to fix this issue:
...
$row[] =
array(
'label' => "Uitslag",
'backgroundColor' => "rgba(146,196,213,0.2)",
'data' => array($autonomie, $competentie, $verbondenheid, $vrijheid, $welbevinden, $energie)
);
...
Then the json should be constructed correct, and the chart should work.
Tipp: Just construct your desired data – structure, in the usual PHP fashion (as needed), and than pass it to the function
json_encode
. It will do the heavy lifting, of converting it into validjson
.
