PHP＆amp; Oracle自动输入值

时间：2015-03-18 01:22:17

标签： php oracle

我有一个select下拉框，它从Products表中获取其值。此下拉框将所选产品的Product_ID传递给insert SQL语句。这些产品中的每一个都有价格（与产品表中的product_id相同）。

如何以实时方式获取所选产品的价格（或者我认为动态是正确的词），以便我可以自动计算总金额？除了价格，我有一个数量和总平方英尺的文本框，这两个是用户手动输入。最后一个框（总金额）是我希望自动计算出现的值。

任何可以让我开始的帮助都将不胜感激！

无法发布图片，所以我很抱歉无法提供视觉效果.__。

编辑：我有一个半工作的jquery，我现在只需要获得所选产品的价格，这样我就可以把它换成var。

Editedit：添加了整个代码。

<?php

}

$conn = oci_connect("dbase", "dbase", "localhost/XE");
$query = "SELECT CUSTOMER_ID, CUSTOMER_FIRST_NAME, CUSTOMER_LAST_NAME FROM customers order by customer_id";
$query2 = "SELECT * FROM PRODUCTS ORDER BY PRODUCT_ID";
$query3 = "SELECT * FROM EMPLOYEES ORDER BY EMPLOYEE_ID";
$statement = oci_parse($conn, $query);
$statement2 = oci_parse($conn, $query2);
$statement3 = oci_parse($conn, $query3);
