Hi all!

I don’t know which is the best way to do solve this "problem".
I have a big modx site (more that 1000 docs) and I added the possibility to comment and vote some articles.
The problem I have is that I don’t want to let these options available for all docs but only for some.

I was thinking to use TV in order to have a checkbox in admin to let me choose if comments / votes will be available or not but I don’t know how can I check the tv value in a snippet like this

if ($tv_value = 1) { $modx->getChunk($comments_chunk); }

Thanks
Sara

Sara,

One way you could easily perform this form of conditional logic is via the PHx plugin: http://wiki.modxcms.com/index.php/PHx

Here is a snippet i just put together for a project to get a chunk if a tv condition is met. You can adapt it to your needs. I built it to work with a check box tv so it simply checks for a value (modx only records check box values, not unchecked). You can set your default TV/chunk or specify them in the call &tv=`` &chunk=``

<?php
// set the variables
$chunk = isset( $chunk ) ? $chunk : "defaultChunk";
$tv = isset( $tv ) ? $tv : "defaultTV"; 

// get chunk and tv values
$chunk_value = $modx -> getChunk( $chunk );
$tv_value = $modx -> getTemplateVarOutput( $tv);

// check if tv and chunk have been selected
if ($tv_value[$tv] != "" || $chunk != "") { 
		$output = $chunk_value; 
	} else {
		$output = "";
	}

return $output;
?>

Thanks all!

dev_cw,
I tried your solution (I think it’s easier and faster)
All it work, but my chunk contents a snippet and it’s not executed, but wrote down sad

What you suggest ??

SOLVED !!!!

Instead of using:

$output = $chunk_value;

I call directly the snippet + some additional parts

$output = '<hr><div id="commenti">';
$params['customfields'] = 'name,email';
$params['subscribe'] = '1';
$params['pagination'] = '4';
$params['badwords'] = '{{parolacce}}';
$params['canmoderate'] = 'Site Admins';
$params['captcha'] = '2';
$params['moderated'] = '1';
$output .= $modx->runSnippet('Jot', $params);
$output .= '</div>';

and it perfectly works!

Sara, if your snippet call is [!snippet!], try running it as [[snippet]] when within the chunk. Glad to see you found a solution that worked for you, btw. wink
