I have a little trouble with a query.
I have this DB structure
PROCESSES process_id process_name
ITENS item_id item_process_id item_name
FILES file_id file_item_id file_name
I run this query to obtain Process ID:
$result = mysql_query("SELECT * FROM processes WHERE process_id='$process_id'");
$row = mysql_fetch_array($result, MYSQL_BOTH);
$process_id = $row['process_id'];
Put this ID in a LOOP to obtain all Itens from table:
$query="SELECT * FROM itens WHERE item_process_id='$process_id'";
$result = mysql_query($query) or die(mysql_error());
$num = mysql_numrows($result);
And call Item name into a LOOP
Problem is when i try to call "file_name" from FILES table. I have tried with a LEFT JOIN to table but with no success. "file_name" variable is blank
Can anyone help me to understand how solve this?
TKS
