Closed 3 years ago.
Right now I have this code:
SELECT * FROM orders, products WHERE product_id=products.id AND `geleverd` = 0
Wich returns as this:
I also have this code for a button:
echo "<a onclick='return window.confirm(\"Weet je zeker dat ".$row['merk']." ".$row['model']." geleverd is?\")' href='change_order_status.php?id=". $row['id'] ."' title='Delete Record' data-toggle='tooltip'><span class='glyphicon glyphicon-ok' style='color:black'></span></a>";
But for some reason id returns a 9 instead of a 1
This is the output of a print of $row
Array
(
[0] => 1
[id] => 9
[1] => 2019-1
[ordernummer] => 2019-1
[2] => 9
[product_id] => 9
[3] => 2
[aantal] => 2
[4] => aaa
[omschrijving] => aaa
[5] => 0
[geleverd] => 0
[6] => 9
[7] => Samsung
[merk] => Samsung
[8] => Tablet S2
[model] => Tablet S2
[9] => 1
[threshold] => 1
)
and:
(
[0] => 3
[id] => 9
[1] => 789
[ordernummer] => 789
[2] => 9
[product_id] => 9
[3] => 10
[aantal] => 10
[4] => test
[omschrijving] => test
[5] => 0
[geleverd] => 0
[6] => 9
[7] => Samsung
[merk] => Samsung
[8] => Tablet S2
[model] => Tablet S2
[9] => 1
[threshold] => 1
)
How can I fix that Id will be 1 for the first row and not 9 and for the second row id will be 3 instead of 9

Answer 1

You need to use Alias for the tables, and combine/rename the columns that you need.
SELECT o.id as orderId, p.id as productId, -all the columns you need with the alias first- FROM orders as o, products as p WHERE o.product_id=p.id AND `geleverd` = 0
