Merge and display 2 database and 2 tables - php

Question

Hey guys i have a problem, there is a page where i need to display data acording to date, but from 2 databases and from 2 tables from each databases,
1 Database name = highmob_comenzi Tables = players and vanzari
2 Database name = highmob_comenzi2 Tables = players and vanzari

<table class='table table-responsive-sm table-bordered table-striped table- sm' border="2px">
<thead>

</tr>
<?php
$servername = "localhost";
$username = "id";
$password = "pw";
$dbname = "highmob_comenzi2";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = ("select *
from highmob_comenzi.players
cross join highmob_comenzi.vanzari
union all
select *
from highmob_comenzi2.players
cross join highmob_comenzi2.vanzari
WHERE statuslivrare >= CURRENT_DATE()");
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "

Answer 1

you can access to the table in the same query without problem eg (assuming the tables have the same struct in both the database):
select *
from highmob_comenzi.players
cross join highmob_comenzi.vanzari
union all
select *
from highmob_comenzi2.players
cross join highmob_comenzi2.vanzari
this is only a sample for accessing to the 2 database in a single query. you must rethink the query with you join and condition
but based on you comment seem you need just (assuming that statuslivrare is a colum of the vanzari table)
select *
from highmob_comenzi.players
cross join highmob_comenzi.vanzari
WHERE vanzari.statuslivrare >= CURDATE()");

Answer 2

<?php
$servername = "localhost";
$username = "ID";
$password = "PW";
$dbname1 = "highmob_comenzi2";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname1 );
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = ("select * from highmob_comenzi2.players cross join highmob_comenzi2.vanzari
");
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "
</thead>
<tbody>
<tr>
<td>HERE DATABASE NAME</td>
<td><a href='vezibilettransportcomenzi.php?id=" . $row["id"] . "' target='_blank' class='btn btn-sm btn-warning'>Tip. Cert.</a></td>
<td>" . $row["id"] . "</td>
<td>
" . $row["statuscomanda"] . "
</td>
<td>" . $row["statuscomandatapiterii"] . "</td>
<td>" . $row["statuslivrare"] . "</td>
<td>" . $row["oralivrare"] . "</td>
<td>" . $row["detaliicomanda"] . "</td>
<td>
" . $row["totaldeplata"] . "</td>
<td>" . $row["avans"] . " <br><a style='color:red;'>" . $row["banipreluati"] . "</a></td>
<td>" . $row["restdeplata"] . "<br><a style='color:red;'>" . $row["banipreluatirest"] . "</a></td>
<td><a href='edit.php?id=" . $row["id"] . "' target='_blank' class='btn btn-sm btn-primary' >Vezi comanda</a></td>
</tr>
";
}
} else {
echo "Nu sunt transporturi!";
}
$conn->close();
?>
