Php 从mysql下拉列表

php forms post

Php 从mysql下拉列表,php,forms,post,Php,Forms,Post,我有一个MySQL数据库，它有4个表：客户、产品、订单和订单详情。 我正在尝试获取具有下拉列表的html或php表单： 1-客户：从客户表中提取 2-项目：从产品表中提取SF 3类：从产品表中提取 然后将信息发布到订单和订单详细信息中。 我得到了从视图中提取数据的表单，但我需要它来发布数据\ 代码如下： <?php include ('connect.php'); mysql_select_db("db") or die(mysql_error()); $sql = "SELEC

我有一个MySQL数据库，它有4个表：客户、产品、订单和订单详情。 我正在尝试获取具有下拉列表的html或php表单： 1-客户：从客户表中提取 2-项目：从产品表中提取SF 3类：从产品表中提取

然后将信息发布到订单和订单详细信息中。 我得到了从视图中提取数据的表单，但我需要它来发布数据\

代码如下：

<?php
include ('connect.php');    
mysql_select_db("db") or die(mysql_error());

$sql = "SELECT DISTINCT Company FROM `values` LIMIT 0, 30 ";

$result=mysql_query($sql);

echo "<select Company='Company'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['Company'] ."'>" . $row['Company'] ."</option>";
}
echo "</select>";

$sql = "SELECT DISTINCT Item, Type FROM `values` LIMIT 0, 30 ";

$result=mysql_query($sql);

echo "<select Item='Item'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['Item'] ."'>" . $row['Item'] ."</option>";
}
echo "</select>";

$sql = "SELECT DISTINCT Type FROM `values` LIMIT 0, 30 ";

$result=mysql_query($sql);

echo "<select Type='Type'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['Type'] ."'>" . $row['Type'] ."</option>";
}
echo "</select>";

?>
<input type="Submit">
在您的问题中，您没有提到表的结构。 让你有自己的公司桌子，或者自己制作

company table
+--------+-----------+-------------------+
| id     |  company  | some other field  |
+--------+-----------+-------------------+
| 1      | abc       | xxxx              |
+--------+-----------+-------------------+
| 2      | def       | xxxx              |
+--------+-----------+-------------------+
//id应该是主键

your product table (each product is made by some company)
+--------+-----------+-------------------+
| id     |  product  | company_id        |
+--------+-----------+-------------------+
| 1      | p1        | 2                 |
+--------+-----------+-------------------+
| 2      | p2        | 1                 |
+--------+-----------+-------------------+
现在你可以做喜欢的事了

//code to show list of companies

 $sql = "SELECT `id`, `company`  FROM  `company` LIMIT 0, 30 ";

$result=mysql_query($sql);

echo "<select Company='Company'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['id'] ."'>" . $row['Company'] ."</option>";
}
echo "</select>";
让您的orders表具有如下结构

+--------+--------------+-------------+--------------+
| id     |  company_id  | product_id  | category_id  |
+--------+--------------+-------------+--------------+
| 1      |    1         | 2           |  8           |
+--------+--------------+-------------+--------------+
同样，这里id是主键和 company_id=company表格中的id、product_id和category_id也是其表格的唯一id

=>创建一个文件save.php并在此处处理表单发送的数据

<?php
    //change according to your settings 
    mysql_connect('localhost','root','');
    mysql_select_db("st") or die(mysql_error());


if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['Submit'])) {
    var_dump($_POST);
    $company_id = $_POST['company_id'];
    $product_id = $_POST['product_id'];
    $category_id = $_POST['category_id'];

    //Note: sanitize and validate data before saving in database 

    $sql = "INSERT INTO orders VALUES('', $company_id, $product_id, $category_id)";

    $result = mysql_query($sql);
    if($result) {
        echo "data saved";
    } else {
        echo "error";
    }

}?>
//阅读有关html中输入字段、php的PDO类、数据清理和验证以及sql查询的更多信息

问题：更新： 当我运行你的代码时。我对你的一些领域感到困惑。你想用这张表格做什么。我的理解 1客户可以添加订单。但为什么会有一个下拉列表来选择客户，而实际上，您是在显示带有客户标签的公司

2一些输入字段- 订单->用户提供订单名称或订单id如果订单id对db不好。bcoz用户可以两次生成相同的订单id。 日期->提交的日期、完成日期或当前日期，如果是当前日期，则应在后端完成。 复选框->为什么复选框不显示 空白和船舶->他们是什么 税务->用户对产品征税，可能是我错了 价格->用户给出每个产品的价格，好的，可能是我错了 总计->用户给出总计，或者按价格*数量+总税金计算。这样就不需要输入框了

在实施什么信息之前，要更加清楚。您希望从用户处获取信息，但该信息是否安全。或者您为用户生成它。因为表单向db注释用户，这可能会导致严重问题。

这是我的表单：

<?php

//change according to your settings 

 include ('connect.php'); 

mysql_select_db("hachemal_compuworld") or die(mysql_error());

?>

<form action="Add_order.php" method = "POST">

            $result=mysql_query($sql);

            while ($row = mysql_fetch_array($result)) {

                echo "<option value='" . $row['Cust_id'] ."'>" . $row['Company'] ."</option>";

            }

我用公司id试过了，下拉列表是空的。然后我尝试了以下方法：$sql=从客户限制中选择不同的公司0,30$result=mysql\u query$sql；回响而$row=mysql_fetch_array$result{echo{$row['Company']}；}echo；没有投递吗？有效吗？你的桌子是什么样子的？我猜是公司id/公司名称？我更新了答案。您可能需要将company_id更改为您使用的id名称，将company_name更改为您在表中使用的名称……好的，下拉列表显示了值，但仍然没有发布到表中。知道下拉列表从一个tablecompany中提取并发布到另一个tableorder。太好了！！工作完美。你真是个天才，谢谢。我需要做更多的事情。此表单发布到两个表：订单和订单详细信息。订单的订单id为自动递增。订单详细信息的交易id为自动增加，订单id为int。我希望刚才gbot在Orders中递增的order_id将其自身复制到order_详细信息中。此外，我还需要能够在表单列中添加行：数量|产品|类别|价格|税收谢谢。现在并不难。但是，首先执行>1-您的order_id of orders表是=我做的相同作业的orders表的id，两者都是自动递增的。2-我认为价格与产品一起存储在产品表中。在products tableprice中添加一个新列。3-税是固定的，正如我所想，或者您可以在products表中添加一个新列来存储税。去做吧。我会在几分钟内更新我的答案。它完全混淆了。我正在努力。请从phpMyAdmin>数据库>表>产品id-auto_increment，product，price，tax，…这是订单表：订单id int11无自动增量日期文本拉丁1瑞典ci客户id int11 Trans\u id int11总计小数10,0状态文本拉丁1瑞典CIT这是订单详细信息表：1 Trans\u id int11无自动增量2订单id int11 3数量int11是空4产品varchar60 5类别varchar30这是我的第一个数据库，请原谅我弄得一团糟：谢谢你的帮助
