所以我正在尝试创建一个网站,我使用一个 php 文件作为索引 (index.php),并且几乎作为控制整个网站的页面。
由于它接收所有请求并使用 返回页面str_replace
,因此一切正常(例如,它使 web 模板正常工作)但问题是我不能在属于的文件中包含 php 代码模板,仅在 index.php 中。
所以我的问题是,有什么办法可以防止str_replace
将 php 代码变成注释?
索引.php:
<?php
//dirs
$pagesDir = "pages/";
$templatesDir = "templates/";
$errorsDir = "errors/";
if (isset($_REQUEST['page'])) {
if ($_REQUEST['page'] != "")
if (file_exists($pagesDir . $_REQUEST['page'] . ".html"))
$page_content = file_get_contents($pagesDir . $_REQUEST['page'] . ".html");
else
if (file_exists($_REQUEST['page'] . ".html"))
$page_content = file_get_contents($_REQUEST['pages'] . ".html");
else
echo "<h1>Page:" . $_REQUEST['page'] . " does not exist! Please check the url and try again!</h1>";
} else {
$page_content = file_get_contents($pagesDir . "home.html");
}
//PLACEHOLDER REPLACEMENT
$page_content = str_replace("!!HEAD!!", file_get_contents($templatesDir . "head.html"), $page_content);
$page_content = str_replace("!!BODY!!", file_get_contents($templatesDir . "body.html"), $page_content);
$page_content = str_replace("!!FOOT!!", file_get_contents($templatesDir . "eofScripts.html"), $page_content);
//RETURN THE CONTENT OF THE PAGE
echo $page_content;
更改后的新调度程序(此有效):
<?php
$templatesDir = "templates/";
$pagesDir = "pages/";
$loggedPagesDir = "templates/logged";
$pageExists = false;
$pageContent = null;
require_once('scripts/php/db_conn.php');
if (isset($_REQUEST['page'])) {
$page = $_REQUEST['page'] . ".php";
}
if (isset($_SESSION['redirect_reason'])) {
$dialogs->alertDialog("warningDialog", $_SESSION['redirect_reason']);
unset($_SESSION['redirect_reason']);
}
if (isset($_SESSION['user_action'])) {
$dialogs->alertDialog("infoDialog", $_SESSION['user_action']);
unset($_SESSION['user_action']);
}
if ($user->is_logged()) { //Only runs beyond this point if user is logged, if not, it will run the other one.
if (isset($_POST['logout_btn'])) {
$user->logout();
$user->redirect("pageDispatcher.php");
}
if (isset($page)) {
if ($page != "") {
if (file_exists($pagesDir . $page)) {
$pageExists = true;
$pageContent = ($pagesDir . $page);
} else {
echo "<h1>Page: " . $page . "does not exist! Please check the url and try again</h1>";
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "loggedhome.php");
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "loggedhome.php");
}
} else { //Only runs beyond this point if user isn't logged.
if (isset($_POST['login_btn'])) {
if ($user->login($_POST['email'], $_POST['password']) == false) {
$dialogs->loginFailed();
} else {
$_SESSION['user_action'] = "Welcome back " . $_SESSION['user_name'];
$user->redirect("pageDispatcher.php");
}
}
if (isset($page)) {
if ($page != "") {
if (file_exists($pagesDir . $page)) {
$pageExists = true;
$pageContent = ($pagesDir . $page);
} else {
echo "<h1>Page: " . $page . " does not exist! Please check the url and try again!</h1>";
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "home.php");
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "home.php");
}
}
?>
<html>
<?php include($templatesDir . "head.html"); ?>
<body>
<?php
if ($user->is_logged()) {
include($templatesDir . "loggedBody.html");
} else {
include($templatesDir . "body.html");
}
include($pageContent);
?>
</body>
</html>
注意:除非出于学习目的,否则不要使用这种方法,它很糟糕,可能很难维护,并且可能最终会很慢,因为我有很多服务器端方法可以在客户端执行。
您阅读页面内容并回显它!不要那样做。使用 include('file.html') 代替。只是为了解释,(如果你必须)这样做:
$pages=['head.html','body.html','eofScripts.html'];
$page=$_REQUEST['page'];
if(in_array($page,$pages)) include($page);
else echo "<h1>Page: $page does not exist!</h1>";
但通常这是不好的编程习惯。正如之前评论中所建议的那样,使用模板引擎。
