i had echo my query and i got result like insert into propertymaster
(area,custname,mob1,mob2,proptype,address,bhk,rent,diposit,sqft,floor,lift)
values ('','','','','','','','','','','','')  basically blank values
are inserting
i want to insert values which are posted by different input types from form

正在发生的事情是空白值分配给vauables; 例如，我写了$ aria = $ _ POST [＆＃39; area＆＃39;]; $咏叹调=＆＃34;空白＆＃34; 请帮我解决这个问题

Answer 1

根据您发布的代码，您遇到了几个问题：

您有两个开放的<html>代码和两个开放的<body>代码。
您的提交按钮前有两个打开的<form>标签，这是无效的HTML，可能导致您的提交按钮不属于包含所有输入的表单，所以当您点击提交按钮，没有任何输入与它一起发送。表单不可嵌套。要解决此错误，请删除第二个打开的<form>代码，将其设置为一个表单。
在使用来自用户的任何输入（例如GET和POST变量）之前，您应该检查它们是否存在，通常使用isset()函数，例如：

if (isset($_POST['aria'])) { $aria = $_POST['aria']; }
您应该从不将用户输入直接放入SQL语句中。这极易受到SQL注入攻击。您应该使用预准备语句并绑定您的参数。

例如，而不是使用：

$addquery="insert into propertymaster (area,custname) values ('$aria','$custname')";
mysql_query($addquery);

您应该使用：

$stmt = $db->prepare("INSERT INTO propertymaster (area,custname) VALUES (':aria',':custname')";

$stmt->bindParams(':aria', $aria);
$stmt->bindParams(':custname', $custname);

$stmt->execute();
