php mysql表单将结果从数据库传递给orignal表单域

我有一个问题，我的所有方法都可以工作，但我无法为我的生活弄清楚如何将sql查询的结果回显到原始表单域行一块查询信息。以下是我的代码示例。php mysql表单将结果从数据库传递给orignal表单域

P.S.我尝试使用变量来保存相关数据来回显sql代码底部的原始表，但它只是在页面底部创建一个重复的表格表。看代码

<html>

下面的PHP代码 - 每个方法的作品，但我想回显他们填充上面的原始表单字段。

我假设你要将表单提交到同一页面，这很好。如果是这样，首先声明你的变量，并将你的SQL移动到你的表单上。然后对于每个表单域，请执行下列操作：

if(isset($_POST[PID]){ 
    $pid = $_POST[PID]; 
}else{ 
    $pid = ""; 
}

在你的HTML，将每个变量相关的表单元素的值，以便它显示如果表单已经提交或者其空如果标有未提交。

<input type="text" value="$pid" size="50" maxlength="7" name="PID">
