Question

I have this code:

add_action( 'delete_post', 'my_delete_function' );
 function my_delete_function($post_id) { 
    global $wpdb;
    $achievement = get_the_category($post_id); 
    $h = $achievement[0]->cat_ID; 
    $s = ''.str_replace('"', '', $h);
    $p = var_dump(htmlentities($s));
   $wpdb->query("INSERT INTO ".$wpdb->prefix."votes (post, votes, guests, usersinks, guestsinks) VALUES('', ".$p.", '', '', '') ") or die(mysql_error());
}

mySQL keeps throwing this error

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' '', '', '')' at line 1

Ive ran the same query in phpMyAdmin, replacing the php vars with values and it works fine

Additionally, ive made sure the the value of $s is just a number by using the echo function on a blank page.

Any help is appreciated

Answer 1

maybe
$wpdb->query("INSERT INTO ".$wpdb->prefix."votes (post, votes, guests, usersinks, guestsinks) VALUES('', '".$s."', '', '', '') ") or die(mysql_error());
