我如何在 php.ini 中从多个选择查询中设置多个变量值。这是php代码(trans.php)
<?php
include('config.inc');
$pname = $_POST['pname'];
$usrname = $_POST['usrname'];
$iname = $_POST['iname'];
$udec = $_POST['udec'];
$usize = $_POST['usize'];
$qty = $_POST['qty'];
$lname = $_POST['lname'];
$p_id = mysql_result(mysql_query("SELECT `id` FROM `project_master` WHERE ( `Project_Code` = '" . $_POST['pname'] . "') "),0);
$user_id = mysql_result(mysql_query("SELECT `u_id` FROM `user` WHERE ( `user_name` = '" . $_POST['usrname']. "') "),0);
$i_id = mysql_result(mysql_query("SELECT `id` FROM `item_master` WHERE ( `item_name` = '" . $_POST['iname'] . "') "),0);
$unit_id = mysql_result(mysql_query("SELECT `id` FROM `unit_mstr` WHERE( `Unit_Name` = '" . $_POST['udec'] . "') "),0);
$loc_id = mysql_result(mysql_query("SELECT `id` FROM `location_mstr` WHERE( `l_name` = '" . $_POST['lname'] . "') "),0);
$sql= " INSERT INTO project_transaction_header(project_id, u_id, item_Id, unit_id,Size, Qty, location_id, Created_On, Created_By, Modified_on, Modified_By) VALUES ('$p_id','$user_id','$i_id',$unit_id','$item_size','$item_qty','$loc_id',now(),'system',now(),'system');";
但我得到了错误
Notice: Undefined index: usrname in C:\xampp\htdocs\alogin\ptrans.php on line 14
Warning: mysql_result(): Unable to jump to row 0 on MySQL result index 6
Notice: Undefined index: iname in ..\..\ptrans.php on line 15

我通过 post 方法从我的 html 页面接收 vaules..
这是我的 HTML 代码,我称之为 PHP Transition.html
<HTML>
