No results from $wpdb->get_row()
I'm trying to read data from my WP db where I've added a custom table. Hereunder the code:
add_shortcode('modifica','f_modifica');
function f_modifica()
{
$chimod = $_POST['chimod'];
echo $chimod; // OK IT PRINTS THE CORRECT VALUE
global $wpdb;
$result = $wpdb->get_row("SELECT * FROM $wpdb->mg_nomi WHERE id_nome = %d",'$chimod');
echo $result->id_nome; // NO RESULTS
}
Well, here is some additional info:
1- mg_nomi is the table name
2- id_nome is the primary key (integer 11)
3- $_POST['chimod'] is the (integer) parameter I receive from another form with submit button and hidden field
I need only one row because I have to put values into fields in order to update them.
Already tried with:
1- $wpdb->get_row("SELECT * FROM $wpdb->mg_nomi WHERE id_nome = '$chimod');
2- $wpdb->get_row("SELECT * FROM $wpdb->mg_nomi WHERE id_nome = '22');
3- $wpdb->get_row($wpdb->prepare(("SELECT * FROM $wpdb->mg_nomi WHERE id_nome = '22'));
4- $wpdb->get_row("SELECT * FROM $wpdb->mg_nomi WHERE id_nome = '$chimod',ARRAY_A"); this one with echo $result['id_nome']
5-perhaps all the other variations of the above...I think...
Already did other query that works great, like
$wpdb->get_results(); or $wpdb->delete();
Does anyone have any ideas?

Thanks to all.
Fixed by assigning the table name to a variable.
$tabella = "mg_nomi"; and updating the query as follow
$result = $wpdb->get_row("SELECT * FROM $tabella WHERE id_nome = '$chimod'");
It works great. I'm going to try also $wpdb->prepare()
Thank you all.
Cheers.
Matteo.
