I have two tables:
Invoices & Invoices Parts
The reason i'm using two tables is because i dont want to save the invoice parts array into one record on the Invoices table and i dont want to save it into multiple records on the Invoices table.
When i submit the data into both tables, how can i link both tables together with the ID if i dont have the ID yet?
$result = mysqli_query($mysqli, "INSERT INTO invoices(labelwarning, status, todaysdate, todaystime, todaysdatetime, avatar, firstname, lastname, mwaid, nextgenid, manager, manageremail, dispatcher, dispatcheremail, techemail, tag, serialnumber, currentequipment, company, address, city, state, zip, contactperson, contactnumber , currentdate, timearrived, timecompleted, login_id) VALUES('$labelwarning', '$status', '$todaysdate', '$todaystime', '$todaysdatetime', '$avatar', '$firstname', '$lastname', '$mwaid', '$nextgenid', '$manager', '$manageremail', '$dispatcher', '$dispatcheremail', '$techemail', '$tag', '$serialnumber', '$currentequipment', '$company', '$address', '$city', '$state', '$zip', '$contactperson', '$contactnumber ', '$currentdate', '$timearrived', '$loginId')");
$result2 = mysqli_query($mysqli, "INSERT INTO invoiceparts(partnumber, partdescription, partprice, partquantity, partdb, login_id) VALUES '$partnumberstring', '$partdescriptionstring', '$partpricestring', '$partquantitystring', '$partdbstring', '$loginId')");
