Yii2: Passing php variables to \yii\web\JsExpression()

[jonny7]

Hi,

I'm trying to use \yii\web\JsExpression() with highcharts and building a custom tooltip, I'm struggling to be able to pass PHP parameters to the function though. I have seen https://github.com/yiisoft/yii2/issues/9609. Is there a way to pass in a php variable so it can be used with \yii\web\JsExpression()

<?php
$var = 'hello';
'formatter' => \yii\web\JsExpression('function(){
       return {$var};
 }')

doesnt the following fulfill your needs?:

<?php
$var = 'hello';
'formatter' => \yii\web\JsExpression('function(){
       return "'.$var.'";
 }')

It should be properly escaped or whitelisted though. Else you'll get into big trouble.

it should be done like this:

<?php
$var = 'hello';
'formatter' => \yii\web\JsExpression('function(){
       return ' . \yii\helpers\Json::htmlEncode($var) . ';
 }')
