QueryFetchArrayAll from multiple tables? - php

Question

I am pulling out data from my "facebook" table using this code that I then display in a table using the foreach() function:
$orders = $db->QueryFetchArrayAll("SELECT id,url,c_amount,amount,date,status FROM `facebook` WHERE `user`='".$data['id']."' ORDER BY `date` DESC LIMIT 30");
How would I go about pulling out data from multiple tables, for example from the "facebook" AND "twitter" table and then displaying it at the same time in my table?
Here is my full code for those that would need that:
<table class="table">
<thead>
<tr>
<td># (ID)</td>
<td>URL</td>
<td>Current Amount</td>
<td>Amount Wanted</td>
<td>Date</td>
<td>Status</td>
</tr>
</thead>
<tbody>
<?
$orders = $db->QueryFetchArrayAll("SELECT id,url,c_amount,amount,date,status FROM `facebook` WHERE `user`='".$data['id']."' ORDER BY `date` DESC LIMIT 30");
if(!$orders){ echo '<tr><td colspan="6" align="center"><b>Noting found!</b></td><tr>';}else{
foreach($orders as $order){
?>
<?
if($order['status'] == 0){
$status = '<label style="color: #999999;">Waiting for supplier</label>';
}
elseif ($order['status'] == 1) {
$status = '<label style="color: #f0ad4e;">In progress</label>';
}
elseif ($order['status'] == 2) {
$status = '<label style="color: #e25856;">Canceled/Refunded</label>';
}
elseif ($order['status'] == 3) {
$status = '<label style="color: #428bca;">Pending admin review</label>';
}
else{
$status = '<label style="color: #94b86e;">Completed</label>';
}
?>
<tr>
<td><?=$order['id']?></td>
<td><?=$order['url']?></td>
<td><?=$order['c_amount']?></td>
<td><?=$order['amount']?></td>
<td><?=date('Y-m-d h:i',$order['date'])?></td>
<td><?=$status?></td>
</tr><?}}?>
</tbody>
</table>

Answer 1

Use the UNION keyword.
Please note that both queries should have the same fields count and the same fields types.
Example :
$orders = $db->QueryFetchArrayAll(
"SELECT id,url,c_amount,amount,date,status FROM `facebook` WHERE `user`='"
. $data['id']
. "' UNION
SELECT field1, field2, field3, field4, field5 FROM `twitter` WHERE some_condition "
);
Hope it helps

Answer 2

You would want to use a union
$orders = $db->QueryFetchArrayAll("SELECT id,url,
c_amount,amount,date,status FROM `facebook`
WHERE `user`='".$data['id']."'
join ORDER BY `date` DESC LIMIT 30
UNION
SELECT id,url,
c_amount,amount,date,status FROM `twitter`
WHERE `user`='".$data['id']."'
join ORDER BY `date` DESC LIMIT 30");
