将变量从表单传递到下一页，并放入sql语句php中

php jquery mysql sql

将变量从表单传递到下一页，并放入sql语句php中,php,jquery,mysql,sql,Php,Jquery,Mysql,Sql,这就是我要做的。我有一个下拉列表或excel类型的外观，我需要从数据库中提取数据。当我选择了一个项目时，我需要通过会话将信息传递到下一页。我有从数据库下拉，但我需要在下拉列表中列出姓名和地址 如果这是不可能的，我可以做一个搜索项目列表，但我需要使id成为一个链接，以将id传递到下一页，在那里我需要建立一个报告 如果你能给我一些这方面的信息，我将不胜感激 下面是我在下拉列表中的代码 代码：全选 <?php // declare database connection variables

这就是我要做的。我有一个下拉列表或excel类型的外观，我需要从数据库中提取数据。当我选择了一个项目时，我需要通过会话将信息传递到下一页。我有从数据库下拉，但我需要在下拉列表中列出姓名和地址

如果这是不可能的，我可以做一个搜索项目列表，但我需要使id成为一个链接，以将id传递到下一页，在那里我需要建立一个报告

如果你能给我一些这方面的信息，我将不胜感激

下面是我在下拉列表中的代码

代码：全选

<?php   
// declare database connection variables.
$host = "localhost";
$username = "root";
$password = "";
$db_name = "sample";
$tbl_name = "tbl_report";

// connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

$sql = "SELECT id, name, address FROM $tbl_name";
$result = mysql_query($sql) or die(mysql_error());

$dropdown = "<form action='report.php' method='post'>"; 

$dropdown .= "<select name='items' class='select'>";

while ($row = mysql_fetch_assoc($result)) {
$dropdown .= '<option value="' . $row['id'] . '">' . 
$row['name'] . ' - ' . $row['address'] . '</option>';;
}
$dropdown .= "\r\n</select>";
$dropdown .= "<input type='submit' name='submit' value='Submit'>";
$dropdown .= "</form>"; //closing the form tag
echo $dropdown;
?>
我需要的是一种将$row['id']传递到下一页并将其放入sql代码中的方法，然后使用get方法在该页的表单上显示信息

以下是页面的设置。选择-report.php这是下拉菜单->report.php的位置

这里是report.php的表单，我需要在其中传递id的值，并执行select*from$tbl_name的sql，其中id=[$post=items]；然后我需要使用$get将所有项目放入下表中：

您可以在如下方式获取所选值时使用jquery

$("#dropdownid").change(function({  var vals = $(this).val(); })
然后，当您重定向到下一页时，将其添加为get参数

if(isset($_REQUEST['submit'])){
     $option = $_POST['items'];
     mysql_query("SELECT * FROM `table_name` WHERE FIELD_NAME = '$options'");
}
您可以使用php会话将值传递到下一页

$_SESSION ['name'] = $value;
您可以从下一页使用php会话获取值

$value = $_SESSION ['name'];
如果您希望方法为get，请删除方法='post'，或者将post更改为get。值应该可以通过$\u GET['items']访问。在查询之前添加print\u r$\u POST并检查正在发布的内容。SQL可注入。此外，如果使用“提交请求”，为什么不使用“如果”设置选项值？OP还需要启动会话。 
$value = $_SESSION ['name'];

    if(isset($_REQUEST['submit'])){
     $option = $_REQUEST['items'];
     mysql_query("SELECT * FROM `table_name` WHERE FIELD_NAME = '$options'");
}
