Salve ragazzi ho questo codice che utilizzo per fare una ricerca con parole multiple su varie tabelle del database dopo averle filtrate mediante dei criteri
purtroppo mi da i seguenti errori:
Warning: Cannot use a scalar value as an array .... on line ....
(line di riferimento - $query[] = "(fname LIKE '%$chiave%'...)
Warning: implode(): Bad arguments. in ... on line ...
(line di riferimento - $query_string = " ...)
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in ... on line ...
(line riferimento - while ($row = mysql_fetch_array ($dati)){ ...)
Qualcuno ha la gentilezza di darmi una mano?
ECCO IL CODICE IN QUESTIONE:

$tutto = "SELECT A.*, B.* FROM members AS A INNER JOIN profiles AS B ON A.mem_id = B.mem_id";
$query = mysql_db_query ($sql_db,$tutto)
or die ("Non riesco ad eseguire la richiesta $tutto");
$righe = mysql_num_rows ($query);
