所以我试图从TABLE页面读取记录，但它总是导致我出错404，我的id名称是headid。我试图学习粗鲁。我想查看非表格形式的记录，但是看起来像输入表单的可打印表单。
这是我的read.php文件：
<?php
require 'crud_database.php';
$headid = null;
if ( !empty($_GET['headid'])) {
$headid = $_REQUEST['headid'];
}
if ( null==$headid ) {
header("Location: read.php");
} else {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM table_head where headid = ?";
$q = $pdo->prepare($sql);
$q->execute(array($headid));
$data = $q->fetch(PDO::FETCH_ASSOC);
Database::disconnect();
}
?>
<?php echo"$headid"?>

这是我的table.php文件，我在那里读取记录：

这是我的文件与我的数据库的链接，因此您可以尝试：https://onedrive.live.com/?cid=ED1942ABAA45D6A5&id=ED1942ABAA45D6A5%21105
答案 0 :(得分：0)
导致404错误的错误有两个：
echo '<a class="btn" href="crud_read.php?id='.$row['headid'].'">Read</a>';
参数id应为headid，因此可在crud_read.php
$headid = null;
if ( !empty($_GET['headid'])) {
$headid = $_REQUEST['headid'];
}
if ( null==$headid ) {
header("Location: read.php");
}
在您的情况下，$headid为null，因此此代码会重定向到不存在的页面read.php。
请注意此重定向，您必须避免无限重定向到同一页面。
