从PHP/MySQL填充HTML加载的表单,php,html,mysql,select,Php,Html,Mysql,Select,我在这里和其他网站上读过很多帖子，它们解释了如何读取MySQL数据库并在HTML表单上显示数据。所有这些信息的问题在于，示例使用PHP构建表单。我的已存在并已加载我的HTML/PHP： <html> <head> <title>Alpaga Wasi - Facture</title> <meta http-equiv="Content-Type" content="text/html;charset=windows-125

我的HTML/PHP：

    <style>
        @media print
        {
        input.Button {display:none;}
        button.Button {display:none;}
        }
    </style>
</head>
<body>
<form action="InvoiceViewFunction.php" method="post">
<?php include("InvoiceForm.php"); ?>
<input class="Button" type="submit" value="Get Invoice" name="nGetInvoice"/>    
</form>
</body>
</html>

input.Button{display:none；}
按钮{显示：无；}
}

行带来了包含表格、tr、td和所有输入字段的HTML。通过这种方式，我可以重用相同的“InvoiceForm”将数据输入数据库和检索数据库

这是我的测试代码，到目前为止，当用户单击“获取发票”按钮时，我已经从数据库中获取了数据

根据操作回答：

创建一个php脚本以接收http请求并从数据库获取数据
在服务器上创建一个名为api.php的php脚本
复制并粘贴下面的示例并保存：



您应该研究ajax。基本上，javascript会向另一个php文件发出请求并异步返回数据。我已经对各种语言HTML、CSS、Javascript、SQL了如指掌。这个Ajax似乎包含了所有混合在一起的内容。我希望找到更简单的东西。如果你使用像jQuery这样的javascript库，这真的很简单。你需要用它的字段值来显示表单吗？我说的对吗？如果你不想使用ajax，那么你需要让表单提交操作与你提供的第一个html/php文件相同，但是有很多条件来确定数据是否存在。最好按照@AustinAllover的建议使用jQueryAjax
<?php
//Connect to database
include("../ConfigFiles/ConnectDB_local_i.php");

    //Populating the variables
    $InvoiceNo = $_POST["nInvoiceNo"];

    //Reading a specific invoice from DB
        echo "<br>Trying to read from DB with invoice = <br>" . $InvoiceNo . "<br>"; //This tells the correct number just fine.

        $query = "SELECT * FROM `invoicedata_table` WHERE InvoiceNo = '$InvoiceNo'";
        $result = $mysqli->query($query) or die($mysqli->error.__LINE__);
        if($result->num_rows > 0) 
        {
            while($row = $result->fetch_assoc()) 
            {
                echo stripslashes($row['ClientName']) . "<br>"; 
            }
        }
        else 
        {
            echo 'NO RESULTS';
