Finding Value in Array using isset

[eluser]mah0001[/eluser]
You can remove all the var_dumps. What is the value for the $subTotal?

Code:

$subTotal = $this->rtui_app->subTotal($storeArray);
var_dump($subTotal);

If $subTotal is not an array you cannot merge a string with the array. I think this is causing all the trouble.

Try changing the $subTotal to an array. e.g.

Code:

$subTotal = $this->rtui_app->subTotal($storeArray);
if (!is_array($subTotal) ){
$subTotal=array($subTotal);
}
$storeArray = array_merge($storeArray, $subTotal);
