I want to add a shortcode which will execute a DB query and return the result. Here's my functions.php:
function get_posts_count($cat){
global $wpdb;
$a = shortcode_atts( array(
'id' => ''
), $cat );
$id=$a['id'];
$count=$wpdb->get_results( "SELECT `count` FROM `wpmy_term_taxonomy` WHERE `term_id`=$id");
foreach($count as $row)
echo '('.$row->count.')';
}
add_shortcode( 'postCount', 'get_posts_count' );
This is the shortcode in the editor:
The value in this case 1 appears above the text Real Estate. How can I make sure it is displayed within the line? Thanks in advance

the shortcode accepts parameters (attributes) and return a result (the shortcode output). If the shortcode produces a HTML then ob_start can be used to capture output and convert it to a string as follows:-
function get_posts_count( $cat ) {
ob_start();
global $wpdb;
$a = shortcode_atts( array(
'id' => '',
), $cat );
$id = $a['id'];
$count = $wpdb->get_results( "SELECT `count` FROM `wpmy_term_taxonomy` WHERE `term_id`=$id" );
foreach ( $count as $row ) {
echo '(' . $row->count . ')';
}
return ob_get_clean();
}
add_shortcode( 'postCount', 'get_posts_count' );
