php - Wordpress $wpdb->get_var results in blank page -


i'm trying simplest wordpress database function return result , shows blank. query works fine in phpmyadmin , returns result want, not via page template in wordpress.

this function running on page template that's based off twentythirteen theme page.php (i replaced the_content() function). code below:

<?php function ag_get_count_to_work(){     global $wpdb;     $num_posts = $wpdb->get_var("select count(*) wp_posts");     if ($num_posts) {        echo "<h1>" . $num_posts . "</h1>";     } else {        die(mysql_error());     } } ?>

i might not have if statement setup correctly, trying without if statement (i.e., return result), result blank, , there no errors shown. can eagle-eyed developer tell me i'm missing please?

this not final function want, i'm trying break problem down origin , might it.

turns out function defined not called. because i'm used putting functions in functions.php file. once called seems work fine.
