[Tip] Passing a Template Variable to a Snippet

It’s very easy to pass the value of a Template Variable to a Snippet.

For example, you could create a Template Variable (text input) called BGColor and pass the value entered by the user into a Snippet as follows:

[[MySnippet? &color=`[*BGColor*]`]]

When the Parser executes it will then output the value of the [*BGColor*] variable into the snippet.

Great tip !

Thanks for sharing !

Yeah, I found out the hard way (with a [*language*] tv) that you can’t use a tv in the snippet code; you have to pass it as an arguement.

first post here. any help would be appreciated.

I can’t seem to properly pass the template variable to my snippet inside a chunk. I know the tv works b/c i display it before my snippet call, but once inside the snippet i can’t access the value.

here’s the code below:

<p>[*statusCode*]</p>
[[routeReservationRequest? &currentStatus=`[*statusCode*]` ]]

The tv value shows in the chunk, but when i echo the value in the snippet it’s empty. I tried to initially just access the tv from within the snippet but not sure how to do that either.

any help is appreciated.

side point: can anyone point me to a good reference on the scope of template variables within modx?

Try the snippet uncached, [!...!]

genius! that did the trick.

Of course you can do it.

$tv_value = $modx->getTemplateVarOutput(’your_var’);
echo ($tv_value[’your_var’]);

Or in Revo:

$tv = $modx->getObject('modTemplateVar'),'TV_name');

Is that a typo or are open "()" allowed in Revo?

Revo is smart enough to correct any possible error in your php code. In fact, you can leave the PHP code sections completely blank and Revo will create them for you.

Seriously, thanks for catching that. I was in a hurry when I dashed it off. Fixed in the post above (I hope).
