如何将 PHP 个变量放入 Div 个标签层

Question

我在将回声放入 div 标签层时遇到问题。我尝试了很多次尝试将其放入 div 标签层，这样我就可以轻松地将结果 "name" 轻松移动到页面，所以当它显示在浏览器上时，它可以在页面的左侧、右侧或中心。在此之前，我尝试在 HTML 中回显它，但没有用。下面是我的页面脚本 -- useracc-test.php

  <?php

//useracc-test.php
session_start();

// require 'lib/password.php';
require 'connect-test.php';
$userName=$_POST['username'];

//$sql = "SELECT name, username FROM users WHERE username = '" . $_POST['username'] . "'";
//$result = $conn->query($sql);
$query = sprintf("select name, username, telno FROM users WHERE username='%s'", mysql_real_escape_string($userName));
$result = $conn->query($query); ?>

<?php while($row=$result->fetch_assoc()): ?>
<div id="satu"><?= $row['name'] ?></div>
<div id="dua"><?= $row['username'] ?></div>
<div id="tiga"><?= $row['telno'] ?></div>
<?php endwhile; ?>

<html>
<head>
<style type="text/css">
#apDiv2 {
    position: absolute;
    left: 51px;
    top: 238px;
    width: 237px;
    height: 93px;
    z-index: 1;
}
#apDiv1 {
    position: absolute;
    left: 50px;
    top: 344px;
    width: 234px;
    height: 104px;
    z-index: 2;
}
</style>
</head>
<body>
<div id="apDiv2"><span class="error"><?php echo $userName; ?></span></div>
<div id="apDiv1"><span class="error"><?php echo $row['telno'] ?></span></div>


</body>
</html>

Answer 1

你可以这样做：

<?php while($row=$result->fetch_assoc()): ?>

<div id="satu"><?= $row['name'] ?></div>
<div id="dua"><?= $row['username'] ?></div>
<div id="tiga"><?= $row['telno'] ?></div>

<?php endwhile; ?>

Answer 2

如果你想在正文中显示结果，那就是你需要回显/输出它们的地方。只需像这样将块复制到 HTML 主体：

<body>
<div id="apDiv2"><span class="error"><?php echo $userName; ?></span></div>
<div id="apDiv1"><span class="error"><?php echo $row['telno'] ?></span></div>

<?php while($row=$result->fetch_assoc()): ?>

<div id="satu"><?= $row['name'] ?></div>
<div id="dua"><?= $row['username'] ?></div>
<div id="tiga"><?= $row['telno'] ?></div>

<?php endwhile; ?>

</body>
</html>
