我已经创建了一个网站,并且希望某些用户能够在看到需要更改的内容后登录并编辑内容。我正在使用password_hash作为密码。
但是现在我对如何让这些用户编辑网站上的内容感到困惑,例如说我有以下代码:
<div class="-container-white" style="padding:128px 16px" id="charities">
<h3 class="-center">SUPPORTING CHARITIES</h3>
<p>Over the years we have been helping raise money for a number of charities.</p>
<p>These include:</p>
<ul>
<li>Cash For Kids</li>
<li>Cancer Research</li>
</ul>
<p>We also have helped numerous organisations out by donating products they can use in their raffles</p>
<p> If you know of any charities or would like to discuss having products donated for raffles please do not hesitate to get in touch</p>
<p>We are proud to to support these charities and can not thank you, customers, enough for helping us do this</p>
<div class="-row-padding -center" style="margin-top:64px">
</div>
</div>
现在,拥有这些用户的目的是使网站更新变得更容易,因此,如果他们发现错误,可以轻松地对其进行更改,而无需要求我输入代码并进行更改。为了使这种情况发生,我需要更改什么,即一旦其中一个管理员用户登录后,就可以对其进行编辑。
如果有帮助,这是我的登录页面,其中包含sql代码:
<?php
// Initialize the session
session_start();
// Check if the user is already logged in, if yes then redirect him to welcome page
if(isset($_SESSION["loggedin"]) && $_SESSION["loggedin"] === true){
header("location: welcome.php");
exit;
}
// Include config file
require_once "config.php";
// Define variables and initialize with empty values
$username = $password = "";
$username_err = $password_err = "";
// Processing form data when form is submitted
if($_SERVER["REQUEST_METHOD"] == "POST"){
// Check if username is empty
if(empty(trim($_POST["username"]))){
$username_err = "Please enter username.";
} else{
$username = trim($_POST["username"]);
}
// Check if password is empty
if(empty(trim($_POST["password"]))){
$password_err = "Please enter your password.";
} else{
$password = trim($_POST["password"]);
}
// Validate credentials
if(empty($username_err) && empty($password_err)){
// Prepare a select statement
$sql = "SELECT id, email, password, last_name, first_name username, FROM admin_users WHERE username = ?";
if($stmt = mysqli_prepare($link, $sql)){
// Bind variables to the prepared statement as parameters
mysqli_stmt_bind_param($stmt, "s", $param_username);
// Set parameters
$param_username = $username;
// Attempt to execute the prepared statement
if(mysqli_stmt_execute($stmt)){
// Store result
mysqli_stmt_store_result($stmt);
// Check if username exists, if yes then verify password
if(mysqli_stmt_num_rows($stmt) == 1){
// Bind result variables
mysqli_stmt_bind_result($stmt, $id, $username, $hashed_password);
if(mysqli_stmt_fetch($stmt)){
if(password_verify($password, $hashed_password)){
// Password is correct, so start a new session
session_start();
// Store data in session variables
$_SESSION["loggedin"] = true;
$_SESSION["id"] = $id;
$_SESSION["username"] = $username;
// Redirect user to welcome page
header("location: welcome.php");
} else{
// Display an error message if password is not valid
$password_err = "The password you entered was not valid.";
}
}
} else{
// Display an error message if username doesn't exist
$username_err = "No account found with that username.";
}
} else{
echo "Oops! Something went wrong. Please try again later.";
}
}
// Close statement
mysqli_stmt_close($stmt);
}
// Close connection
mysqli_close($link);
}
?>

在我可以正常工作之前,welcome.php页面只是目前的标准页面。

允许登录用户编辑您网站的HTML,以便对网站的所有其他用户进行更改,这是一件相当复杂的事情。
如果您要这样做,那么您要走的路要走,还有很长的路要走。
