Sorry for the basic question, just a bit confused as to what is going on here. I have some PHP running in Wordpress, I am able to run html, php and javascript all from within one file. For example:
<?php
//query WP for the tag
$wp_getTag = $wpdb->get_results(
"
SELECT name
FROM $wpdb->mydb_wor1.ukj_terms
INNER JOIN ukj_term_taxonomy
ON (
ukj_terms.term_id = ukj_term_taxonomy.term_id
)
WHERE ukj_term_taxonomy.taxonomy LIKE 'post_tag'
"
);
$json = json_encode($wp_getTag);
?>
<script type="text/javascript">
// pass the value to js
var JsonTags = <?php echo $json ?>;
</script>
So all the above works. I am grabbing some info from wp and then assigning it's value to a JS variable using echo. But it is not clear what is going on here? is the Javascript running on the server instead of the client?
