Hi list,
I have a class to perform my tasks to bd, among than there's this function
function executa($sql="") {
if($sql == "") {
$this->resultado = 0;
$this->numrows = 0;
$this->row = -1;
}
$this->resultado = mysql_query($sql,$this->conexao->id);
$this->numrows = mysql_num_rows($this->resultado);
}
everything works fine, except when I tri to insert a record. It inserts, but
give an error
"Warning: Supplied argument is not a valid MySQL result resource in
/home/restricted/home/papagaiodigital/public_html/recrutamento/includes/clas
sesql.inc on line 22"
line 22 is "$this->numrows = mysql_num_rows($this->resultado);"
what's the problem??
Thank's n advance
Rodrigo Peres
