Using template variables within Snippet

Hey I am trying to get the count for blog posts within a collection however I want to be more specific.
I want to be able to count the children but only ones that tag (template variable) match a certain one.

I have this code that will return the count of the whole collection:
```
<?php
$count = 0;
$parent = isset($parent) ? (integer) $parent : 0;
if ($parent > 0) {
    $criteria = array(
        'parent' => $parent,
        'deleted' => false,
        'published' => true,
    );
    $count = $modx->getCount('modResource', $criteria);
}
return (string) $count;
```
But i would like to add to the $criteria array something like " 'tv.filterTag' => 'blogTag1' "

Is this possible?

Thank you in advance
Ryan

If your tag TV does not use @INHERIT and doesn't have a default value (which will make things significantly faster), you can do this (untested):
```
$tvId = 12; /* Change this to the ID of your tag TV */
$searchTag = 'blog1;

$c = array(
    'tmplvarid' => $tvId, 
    'value' => $searchTag,
);

$count = $modx->getCount('modTemplateVarTemplate', $c);
```
This assumes that you can count on an exact match for the tag and the search term. If the user is entering the search term, you'll want to use trim() on it (and sanitize it!!). [ed. note: BobRay last edited this post 7 years, 9 months ago.]
