PHP show table from record with same id - php

Question

I want to return to the user a table that shows his orders but when a user orders one product the table is ok but in the moment that orders 2 product they get 2 lines with the same ID but different ProductID same total price.
$email = strval($_SESSION["email"]);
$TabellaOrdini = "SELECT DISTINCT ordini.IDOrdini, clienti.Indirizzo,
clienti.Nome, clienti.Cognome, ordini.StatoConsegna,
prodotti.Descrizione, ordini.TotaleOrdine,
pacco.IDProdotti, pacco.Quantita
FROM (((clienti NATURAL JOIN ordini)
JOIN pacco ON ordini.IDPacco = pacco.IDPacco)
JOIN prodotti ON pacco.IDProdotti = prodotti.IDProdotti)
WHERE clienti.IDClienti = ordini.IDClienti
AND clienti.Email = '$email'
ORDER BY ordini.IDOrdini";
$CheckOrdini = "SELECT insertphpordini.IDOrdini,
concat(insertphpordini.Descrizione,' x ',insertphpordini.Quantita) AS Risultato
FROM insertphpordini
WHERE insertphpordini.Email = '$email'
AND insertphpordini.IDOrdini IN
( SELECT insertphpordini.IDOrdini
FROM insertphpordini
GROUP BY insertphpordini.IDOrdini
HAVING COUNT(IDOrdini)>1
)";
$result = $conn -> query($TabellaOrdini);
$result2 = $conn -> query($CheckOrdini);
echo "<table id='customers'>";
echo "<tr><th colspan=7>Ordini</th></tr>";
echo "<tr>";
echo "<td><b>IDOrdine</b></td>";
echo "<td><b>Nome</b></td>";
echo "<td><b>Cognome</b></td>";
echo "<td><b>Indirizzo</b></td>";
echo "<td><b>Stato Consegna</b></td>";
echo "<td><b>Prodotto</b></td>";
echo "<td><b>Totale Ordine</b></td>";
while($row = $result -> fetch_assoc()) {
echo "<tr>";
echo "<td> $row[IDOrdini]</td>";
echo "<td> $row[Nome]</td>";
echo "<td> $row[Cognome] </td>";
echo "<td> $row[Indirizzo] </td>";
echo "<td> $row[StatoConsegna] </td>";
echo "<td> $row[Descrizione] / $row[Quantita]</td> ";
echo "<td> $row[TotaleOrdine]€ </td>";
echo "</tr>";
}
echo "</table>";
the query $TabellaOrdini get all values from a user whit that email and the query $CheckOrdini get only the values with the same ID and concat the Description and quantity as Risultato.
My goal is that is possible to have 1 order with 1 ID and in Product(row 6 from left of the table) have "ProductName1/Quantity1, ProductName2/Quantity2"

Answer 1

Use GROUP_CONCAT() to combine values from multiple rows into a single column.
$TabellaOrdini = "SELECT ordini.IDOrdini, clienti.Indirizzo, clienti.Nome, clienti.Cognome, ordini.StatoConsegna,
prodotti.Descrizione, ordini.TotaleOrdine, GROUP_CONCAT(pacco.IDProdotti, '/', pacco.Quantita) AS Prodotto
FROM clienti
NATURAL JOIN ordini
JOIN pacco ON ordini.IDPacco = pacco.IDPacco
JOIN prodotti ON pacco.IDProdotti = prodotti.IDProdotti
WHERE clienti.IDClienti = ordini.IDClienti AND clienti.Email = '$email' ORDER BY ordini.IDOrdini
GROUP BY ordini.IDOdini";
It's also not necessary to group your joins with ().
And you should stop substituting variables directly into SQL, and instead use prepared statements with bind_param().

Answer 2

You can use better display of Orders with Order ID, Customer details, Date in one row along with a drop down with all detailed products and quantities. This way you are not limited with tabular display option.
Else, you can use GROUP_CONCAT with ordini.IDOrdini (your OrderID) and display products as "product01, product02, product03" for same Order01 for instance.

Or you can ajax it out for large child product sets :

NOTE: Please ensure PHP security and try to follow some design pattern for a clean code. Look for Database Object and Binding input parameters with $conn->prepare [https://www.php.net/manual/en/mysqli.quickstart.prepared-statements.php]
