這是我正在嘗試做的事情。我有一個下拉式（和/或Excel類型的外觀），我需要從數據庫中提取數據。當我選擇一個項目時，我需要通過會話將信息傳遞到下一頁。我有從數據庫拉下拉，但我需要在下拉列表中列出名稱和地址。從形式傳遞變量到下一頁，並將其放入sql語句php
如果這是不可能的，我可以做一個搜索項目的列表，但我需要使id成爲一個鏈接，將id傳遞到我需要構建報告的下一頁。
如果你可以給我一些這方面的信息，我將不勝感激。
以下是我對代碼的下拉
代碼：選擇所有
<?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 $dropdown;
?>
我需要做的是通過ID到下一個頁面，並有$ ID顯示在我的下一個sql語句的代碼。
這裏是我對下一頁sql語句的代碼。
select * from $tbl_name where id = (this is where I get hung up on.)
我需要的是在$行[「身份證」]傳遞到下一個頁面，並放進了SQL代碼，然後使用get方法來顯示該頁面的表單上的信息的方式。
這裏是頁面的設置。 select-report.php（這是下拉的地方） - > report.php。
這裏是report.php的形式，我需要繼承id的值，並執行sql的select * from $ tbl_name，其中id = [$ post = items];然後，我需要使用$得到擺在下面的表格中的所有項目：

刪除'方法='post''，如果你希望它是'GET'（或更改'POST'到'GET'）。值應該可以通過'$ _GET ['items']'來訪問。 – chris85
在查詢前添加'print_r（$ _ POST）'並檢查發佈的內容。 –
