Question

I’m very new to drupal and i need to query a table and pass a result from that query to my page.tpl file as a variable. Ive tried for hours but nothing i find works.

php code in template.php

<?php
 $result = db_select("SELECT COUNT(node.nid) AS num FROM node WHERE node.type = 'service'");
 foreach ($result as $record) {
    $number = $record->num;
 }
 return $number;

I even tried adding an echo 'hello world'; but that didnt show up either.

Code in page.tpl

 <?php if ($number > 0) { ?>
    testing
 <?php } ?>

There are two nodes with the type as service. Any help would be great. thanks.

You need to use a hook in your template.php file.

For example (replace THEME_NAME with your theme’s name):

function THEME_NAME_preprocess_page(&$vars) {   
    $vars['foo'] = "bar";
}

This will pass a variable called “foo” to your page.tpl.php file.
