Combine results for SQL query - php

Question

I am in a bit of a pinch. I am using WHMCS and building a custom report but am running into trouble with one of my queries. Here is an overview:
I have 2 tables; tblinvoices which has the subtotal, tax, total, etc. of the invoice and tblinvoiceitems which has the individual line items that appear on the invoice. I am wanting to run a query that returns all of the individual line items and their price which I have been able to do. I run into problems when I do 'GROUP BY' and group the results by invoice numder, then it only returns the first line item for each invoice. I want to group them by invoice number so it only has 1 line in the report. Here is my query:
$query = "SELECT date_format(tblinvoices.datepaid,'%m-%d-%Y') AS datepaid,
tblinvoices.userid,
tblinvoices.id,
tblinvoices.subtotal,
tblinvoices.credit,
tblinvoices.tax,
tblinvoices.tax2,
tblinvoices.total,
tblinvoices.taxrate,
tblinvoices.taxrate2,
tblinvoiceitems.description,
tblinvoiceitems.amount,
tblinvoices.status,
FROM tblinvoices
INNER JOIN tblinvoiceitems ON tblinvoices.id = tblinvoiceitems.invoiceid
GROUP BY tblinvoices.id";
$result = mysql_query($query);
# Math Operations
$statement = array();
$count = 0;
if ($result !== false) {
while ($data = mysql_fetch_object($result)) {
$invoiceid = $data->id;
$datepaid = $data->datepaid;
$description = $data->description;
$item_amount = $data->item_amount;
$subtotal = $data->subtotal;
$credit = $data->credit;
$tax = $data->tax;
$tax2 = $data->tax2;
$total = $data->total;
if ($export != true) {
$client_link = '<a href=clientssummary.php?userid='.$data->userid.'>'.$data->userid;
$invoice_link = '<a href=invoices.php?action=edit&id='.$data->id.'>'.$data->id;
}
else {
$client_link = $data->userid;
$invoice_link = $data->id;
}
if (strpos($description, 'Setup') !== false) {
$setup = $item_amount;
}
else {
$setup = 0;
}
if (strpos($description, 'Addon') !== false) {
$addon = $item_amount;
}
else {
$addon = 0;
}
if (strpos($description, 'Tax Guide: No => Yes') !== false) {
$taxguide = $item_amount;
}
else {
$taxguide = 0;
}
if (strpos($description, 'Reading Rack Bundle') !== false) {
$reading = $item_amount;
}
else {
$reading = 0;
}
if (strpos($description, 'Toolkit Bundle') !== false) {
$toolkit = $item_amount;
}
else {
$toolkit = 0;
}
$hosting = $subtotal - $setup - $addon - $taxguide - $reading - $toolkit;
$statement[$invoiceid."_".$count] = array($datepaid,$client_link,$promo,$dtn,$company,$state,$invoice_link,$setup,$addon,$taxguide,$reading,$toolkit,$hosting,$subtotal,$credit,$tax+$tax2,$total);
$count++;
}
}
foreach ($headings AS $k=>$v) {
$reportdata["tableheadings"][] = $v;
}
//ksort($statement);
foreach ($statement AS $invoiceid=>$entry) {
$reportdata["tablevalues"][] = array(
$entry[0], // datepaid
$entry[1], // clientid
$entry[2], // promocode
$entry[3], // dtn
$entry[4], // companyname
$entry[5], // state
$entry[6], // invoiceid
formatCurrency($entry[7]), // setup
formatCurrency($entry[8]), // addon
formatCurrency($entry[9]), // taxguide
formatCurrency($entry[10]), // reading
formatCurrency($entry[11]), // toolkit
formatCurrency($entry[12]), // hosting
formatCurrency($entry[13]), // subtotal
formatCurrency($entry[14]), // credit
formatCurrency($entry[15]), // tax
formatCurrency($entry[16]) // total
);
}
mysql_free_result($result);
I will be happy to provide any additional information/code if it helps. I though this might be a more general type question...thanks!

Answer 1

With the result you are describing your result set would look like:
userid | id | subtotal | credit | tax | status | desc | amount
______________________________________________________________
1 | 1 | 20 | 0 | .7 | 1 | item1| 10
1 | 1 | 20 | 0 | .7 | 1 | item2| 10
1 | 2 | 30 | 0 | 2.1 | 1 | item3| 15
1 | 2 | 30 | 0 | 2.1 | 1 | item3| 15
1 | 3 | 10 | 0 | .7 | 0 | item1| 10
1 | 4 | 1 | 0 | .07 | 0 | item4| 1
Is this what you are looking for?

Answer 2

So try group by invoice.id and invoice.userid, and then maybe invoice.subtotal....
May run into some issues if you later decide to aggregate anything but this should do it.
