Question

这是我的代码我的目标是能够从数据库中获取数据并将其放在文本框中，以便用户可以更新其配置文件。我还没有得到更新功能。现在我想弄清楚如何在文本框中显示数据

<?php

 $userID = htmlspecialchars($_GET["userID"]);
 $lastName = htmlspecialchars($_GET["lastName"]);
 $_SESSION["userID"] = $userID;

include 'inc/connect.php';
$query = "SELECT * FROM USERS WHERE userID = '$userID'";

$result = mysqli_query($link, $query) or die(mysql_errno());
$row = mysqli_fetch_assoc($result); 

 ?>

<div class="container">
<h1> <?php if(isset($_SESSION['username'])) { 
echo  $_SESSION['username'];
echo "'s Profile";
} ?>   
</h1>
<form class="form-horizontal" action="func/func_user_profile.php" method="post">
<div class="form-group">
    <label class="control-label col-sm-2"> Email:</label>
    <div class="col-sm-10">
        <input type="email" class="form-control" name="email" value="<?php echo $row["email"];?>">
    </div>
</div>
<div class="form-group">
    <label class="control-label col-sm-2"> Password:</label>
    <div class="col-sm-10">
        <input type="password" class="form-control" name="password" value="<?php echo $row["password"];?>">
    </div>
</div>
<div class="form-group">
    <label class="control-label col-sm-2"> Current monthly expenses:</label>
    <div class="col-sm-10">
        <input type="text" class="form-control" name="monthlyExpenses" value="<?php echo $row["monthlyExpenses"];?>">
    </div>
</div>


<div class="form-group" id="submit">
<input type="submit" class="btn btn-success" value="Update Profile" >
<input type="button" class="btn btn-danger" onClick="window.location.replace('welcome.php')" value="cancel">
</div>
</form>
 </div>


 <?php
 include 'inc/footer.php';
 ?>


  </body>
  </html>

我测试了你的代码，它确实显示了数据库中的信息。如果它没有显示任何内容，那应该是因为你的连接有问题。

<?php

 $userID = "1";
 $lastName = "Boo";
$server = "localhost";
$userName = "root";
$password = "";
$database = "test";




$conn =  mysqli_connect($server,$userName,$password , $database);
$query = "SELECT * FROM Boo WHERE userID = '$userID'";

$result = mysqli_query($conn, $query) or die(mysql_errno());
$row = mysqli_fetch_assoc($result); 

 ?>
<html>
<head>

</head>
<body>
<div class="container">
<h1> 
</h1>
<form class="form-horizontal" action="func/func_user_profile.php" method="post">
<div class="form-group">

    <label class="control-label col-sm-2"> Email:</label>
    <div class="col-sm-10">
        <input type="email" class="form-control" name="email" value="<?php echo $row["email"];?>">
    </div>
</div>
<div class="form-group">
    <label class="control-label col-sm-2"> Password:</label>
    <div class="col-sm-10">
        <input type="password" class="form-control" name="password" value="<?php echo $row["password"];?>">
    </div>
</div>


<div class="form-group" id="submit">
<input type="submit" class="btn btn-success" value="Update Profile" >
<input type="button" class="btn btn-danger" onClick="window.location.replace('welcome.php')" value="cancel">
</div>
</form>
 </div>




  </body>
  </html>

如果不同，请使用我使用过的连接。

我试图从我的数据库中提取数据并将其放入文本框中，以便更新。
