Calling a parameter within a snippet.

Hi,

I’ve set up my snippet call within my chunk to look as follows:

[!tax? &param1 = `[+price_net+]`]

And while that does get through to my snippet, I then can’t work out how to call the value that I passed it.

I’ve tried variations on the following:

echo &param1;
or
$test = &param1;
echo $test;

But the only thing it prints out is, &param1 - so I’m assuming that I’m doing it wrong!

Any help would be appreciated!

Thank you

Sorry! I solved this myself just minutes after posting! So I thought for anyone else who was struggling like me, I would direct them to the thread I accidentally stumbled upon my answer on!

Thanks!

try

& is just a concatenate symbol, while variables are preceded by a $ symbol.

Also, I’d better get used to leave out spaces in snippet calls:

This might seem like a silly question, but why is it better to leave out spaces in a snippet call?

Thanks

Don’t know why not; the parameter name and its value are put through the PHP trim() function after they are broken up into an array using the PHP explode() function.
