I need to insert a new row in to a table, then grab the ID of that row and update another table. This is what I have:
$leadSQL="INSERT INTO $leadsTable (leadName, leadStatus, leadDescription, leadOpportunity, leadSource, leadSourceDescription, id, leadSince, contactID)
VALUES ('$_POST[leadName]', '$_POST[leadStatus]', '$_POST[leadDescription]', '$_POST[leadOpportunity]', '$_POST[leadSource]', '$_POST[leadSourceDescription]','$_POST[id]','$leadSince','$_POST[contactID]')";
$leadQuery = mysql_query($leadSQL);
$lastLeadID = mysql_insert_id();
$updateContactSQL = "UPDATE $contactsTable SET leadID = $lastLeadID WHERE contactID = $_POST[contactID]";
$updateContactQuery = mysql_query($updateContactSQL);
Everything works fine.. except that it inserts duplicate rows into the leads table. I have tried putting the update query into an if statement and it did the samething(this was just to try "something"). If I remove $lastID = mysql_insert_id(); it inserts just one row but obviously does not update the contacts table. So I am pretty sure it has to to with mysql_insert_id(). I need it to update the contacts table with the new id of the row inserted into the leads table. Any ideas would be greatly appreciated.
