我试图从一个表中获取所有值,从另一个表中获取一些值,并使用php和html显示它们。这是我试图修改的演示销售点程序。
我要修改的部分是销售报告页面,最初我有TRANSACTION ID
,DATE
,INVOICE NUMBER
,AMOUNT
和REMARKS
。我想从另一个表中添加一些值(即销售" NAME"和" QTY")。
这是我做的:
<?php
include('../connect.php');
$d1=$_GET['d1'];
$d2=$_GET['d2'];
$result = $db->prepare("SELECT sales.* , sales_order.name, sales_order.qty FROM sales,sales_order WHERE date BETWEEN :a AND :b");
$result->bindParam(':a', $d1);
$result->bindParam(':b', $d2);
$result->execute();
for($i=0; $row = $result->fetch(); $i++){
?>
<tr class="record">
<td>STI-000<?php echo $row['transaction_id']; ?></td>
<td><?php echo $row['date']; ?></td>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['invoice_number']; ?></td>
<tf><?php echo $row{'invoice_number'};?></td>
<td><?php
$dsdsd=$row['amount'];
echo formatMoney($dsdsd, true);
?></td>
<td><?php echo $row['type']; ?></td>
</tr>
<?php
}
?>
</tbody>
<thead>
<tr>
<th colspan="4" style="border-top:1px solid #999999"> Total </th>
<th colspan="2" style="border-top:1px solid #999999">
<?php
function formatMoney($number, $fractional=false) {
if ($fractional) {
$number = sprintf('%.2f', $number);
}
while (true) {
$replaced = preg_replace('/(-?\d+)(\d\d\d)/', '$1,$2', $number);
if ($replaced != $number) {
$number = $replaced;
} else {
break;
}
}
return $number;
}
$d1=$_GET['d1'];
$d2=$_GET['d2'];
$results = $db->prepare("SELECT sum(amount) FROM sales WHERE date BETWEEN :a AND :b");
$results->bindParam(':a', $d1);
$results->bindParam(':b', $d2);
$results->execute();
for($i=0; $rows = $results->fetch(); $i++){
$dsdsd=$rows['sum(amount)'];
echo formatMoney($dsdsd, true);
}
?>
</th>

和sales
的键是字段sales_order
,您必须使用INNER JOIN(或LEFT JOIN,取决于您的需要)将两个表连接为以下:
invoice_number
如果链接两个表的键是其他的,那么只需更新$result = $db->prepare("SELECT sales.* , sales_order.name, sales_order.qty FROM sales INNER JOIN sales_order ON sales.invoice_number = sales_order.invoice_number WHERE sales.date BETWEEN :a AND :b");
以匹配好的列名称
另外,不要忘记在连接表时在每个字段之前添加表的名称,因为如果在多个表中具有相同的字段名称,它将给出错误,因为mysql不知道在哪个表中它必须从中获取数据。
