No results from $wpdb->get_row()












-2















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?

  • '$chimod' - that is a text literal containing the literal characters $, c, h and so on. You should go read php.net/manual/en/language.types.string.php

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.
