Question

我正在创建一个脚本，该脚本从数据表中选择数据，然后显示该数据行中的所有信息，并允许您编辑文本。当前框中没有显示任何信息：

所以有3个文件：

文件编号1：输入ID编号：

<!DOCTYPE.html>
<html>
<head>
    <title></title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<HTML>
<BODY>
<form method="post" action="export1.php">
Enter ID:<input type="Text" id="id" name="id"><br>
<input type="Submit" name="Submit ID" value="Submit">
</form>


</BODY>
</HTML>

文件编号2：用于编辑数据的选项：

<?php

$db = mysqli_connect("somedb", "someuser", "somepassword");
mysqli_select_db($db,"leadlist");
$id=$_POST['export'];
mysqli_query($db, "SELECT * FROM `leadlist` WHERE id=$id");

$id = mysqli_real_escape_string($link, $_REQUEST['id']);
$fname = mysqli_real_escape_string($link, $_REQUEST['fname']);
$sname = mysqli_real_escape_string($link, $_REQUEST['sname']);
$address = mysqli_real_escape_string($link, $_REQUEST['address']);
$email = mysqli_real_escape_string($link, $_REQUEST['email']);
$phone = mysqli_real_escape_string($link, $_REQUEST['phone']);
$package = mysqli_real_escape_string($link, $_REQUEST['package']);
$active = mysqli_real_escape_string($link, $_REQUEST['active']);
$mac = mysqli_real_escape_string($link, $_REQUEST['mac']);

?>
<!DOCTYPE.html>
<html>
<head>
    <title></title>
    <link href="userscript.css" type="text/css" rel="stylesheet">
</head>
<body>
    <div id="textentryhead">
        <h1>Reave</h1>
    </div>
    <div id="textentry">
    <div>
        <form action="exportcode1.php" method="post">
    <p>
        <label for="firstName">First Name :</label><br>
        <input type="text" name="fname" placeholder="<?php echo $fname ?>" id="fname">
        <hr>
    </p>
    <p>
        <label for="lastName">Last Name :</label><br>
        <input type="text" name="sname" placeholder="<?php echo $sname ?>" id="sname">

    <p>
        <label for="emailAddress">Address :  </label><br>
        <input type="text" name="address" placeholder="<?php echo $address ?>" id="address">
        <hr>
    </p>
     <p>
        <label for="firstName">Email Address :   </label><br>
        <input type="text" name="email" placeholder="<?php echo $email ?>" id="email">
        <hr>
    </p>
    <p>
        <label for="lastName">Phone Number :</label><br>
        <input type="text" name="phone" placeholder="<?php echo $phone ?>" id="phone">

        <label for="emailAddress">Package Type :</label><br>
        <input type="text" name="package" placeholder="<?php echo $package ?>" id="package">
        <hr>
    </p>
      <p>
        <label for="emailAddress">Package Status :</label><br>
        <input type="text" name="active" placeholder="<?php echo $active ?>" id="active">
        <div id="help"><h6><a href="help.php">Help</a></h6></div>
        <hr>
    </p>
    <p>
        <label for="emailAddress">MAC Address :</label><br>
        <input type="text" name="mac" placeholder="<?php echo $mac ?>" id="mac">
        <hr>
    </p>
    <input type="submit" value="Submit">
</form>
    </div>
</div>
</body>

文件编号3：将新数据添加到其他数据表中：

<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("");

// Check connection
if($link === false){
    die("ERROR: Could not connect. " . mysqli_connect_error());
}

$fname = mysqli_real_escape_string($link, $_REQUEST['fname']);
$sname = mysqli_real_escape_string($link, $_REQUEST['sname']);
$address = mysqli_real_escape_string($link, $_REQUEST['address']);
$email = mysqli_real_escape_string($link, $_REQUEST['email']);
$phone = mysqli_real_escape_string($link, $_REQUEST['phone']);
$package = mysqli_real_escape_string($link, $_REQUEST['package']);
$active = mysqli_real_escape_string($link, $_REQUEST['active']);
$mac = mysqli_real_escape_string($link, $_REQUEST['mac']);


$sql = "INSERT INTO CData (fname, sname, address, email, phone, package, active, mac) VALUES ('$fname', '$sname', '$address', '$email', '$phone', '$package', '$active', '$mac')";
if(mysqli_query($link, $sql)){

                mysqli_close($conn);
                header("Location: ");




                exit;

} else{
    echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}

// Close connection
mysqli_close(

因此，如果有人可以帮助我完成这项工作，那就太好了。：）
