【问题描述】:
CREATE TABLE onecanteen (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
Items_wholesale CHAR(30) NOT NULL,
Items_retail CHAR(30) NOT NULL,
Ammount_recive CHAR(30) NOT NULL,
items_quantity Char(30)NOt Null,
)
插入数据:
<?php
include_once 'dbconfig.php';
if(isset($_POST['btn-save']))
{
$wholesale = $_POST['Items_wholesale'];
$retail = $_POST['Items_retail'];
$quantity = $_POST['items_quantity'];
$recive = $_POST['Ammount_recive'];
if($crud->create($wholesale,$retail,$quantity,$recive))
{
header("Location: add-data.php?inserted");
}
else
{
header("Location: add-data.php?failure");
}
}
?>
php初学者 创建/读取/更新/删除 通常数据存储在 MySQL 数据库中 存储数据后,我在获取数据时执行下面提到的数学运算
<td> <?php print($row['id']); ?></td>
<td><?php print($row['Items_wholesale']); ?></td>
<td><?php print($row['Items_retail']); ?></td>
<td><?php print($row['items_quantity']); ?></td>
<td><?php print($row['Ammount_recive']); ?></td>
<td><?php echo $row['Items_retail'] * $row['items_quantity'] ?></td>
<td><?php echo $row['Items_wholesale'] * $row['items_quantity'] ?></td>
<td><?php echo ($row['Items_retail'] * $row['items_quantity'] )-($row['Items_wholesale'] * $row['items_quantity']) ?></td>
在这里我看到了我所有的记录
<!-- showing whole record add delet record -->
<div class="clearfix"></div>
<div class="container">
<a href="add-data.php" class="btn btn-large btn-info"><i class="glyphicon glyphicon-plus"></i> Add Records</a>
</div>
<div class="clearfix"></div><br />
<div class="container">
<table id="table1" class='table table-bordered table-responsive'>
<tr>
<th >#</th>
<th >Wholesale</th>
<th >retail</th>
<th >Quantity</th>
<th >wholesale total</th>
<th >Retail total</th>
<th >profit</th>
<th >Recive ammount </th>
<th colspan="2" align="center">Actions</th>
<?php
$query = "SELECT * FROM onecanteen";
$records_per_page=3;
$newquery = $crud->paging($query,$records_per_page);
$crud->dataview($newquery);
?>
<tr>
程序完美地从 onecanteen 表中获取数据 现在我想总结所有列 hlpe 我该怎么做??
【问题讨论】:
-
对所有列求和?你的意思是什么,列数据是什么?你只能对数字求和。你能解释一下你试图通过那个“SUM”实现什么吗?
-
所有输入都是数字
-
结果应该是什么?每列分开?还是一起?
-
是的!每列单独总计..
