Please help with this value pickup code

How to fix a ChronoForms value pickup code that fails to output a dynamic price.

Overview

The issue occurs when using complex variable syntax inside curly braces in PHP, which prevents the code from executing correctly.
Simplify the code by keeping only the variable name inside the curly braces and construct the dynamic key separately before using it.

Hello

I am not able to make this code work:

< ?php echo "\n         {$prices['frt_'.$form->data['currency'].'_afkv']}"; ? >

I want to add the [currency] in place of "afkv" the output would be : frt_9_3

9 = USD
3 = device 1

Thanks

Ron

Hi,

I have tried this code but I cannot find the error as it does not work:

< ?php 
$price_string = $form->data['frt'].'_'.$form->data['currency'].'_'.$form->data['device'];
$freight_value += "\n         {$prices[$price_string]}"; 
?>

Thanks

Ron

Hi Ronn,

We can't provide a free service for debugging user's bad PHP :-(

But - in this case the {$variable} syntax will not work if you add a string inside the {} - keep it just to the variable name.

Thanks for that advice Bob.

I will keep it in mind.

Best wishes
