PHP:htaccess 默认变量

发布于 2024-09-25 03:01:15 字数 1053 浏览 9 评论 0原文

我想为 url 末尾的查询设置默认变量

.htaccess 文件按如下方式重定向 url:

http://www.server.com/folder/subfolder/index.php?page="some-page-name"

显示 url

http://www.server.com/folder/some-page-name


如果未设置页面名称,则

http://www.server.com/folder/

,如下所示:默认值为“index” ”。我可以使用 php 函数 header("location:url") 但如果我不想要的 url... 则会在末尾显示“index”部分。



访问内容

   Options -Indexes

    <IfModule mod_rewrite.c>
    RewriteEngine On
    #RewriteCond %{REQUEST_URI} !^(/index\.php|/img|/js|/css|/robots\.txt|/favicon\.ico)
    RewriteBase /folder/
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !^.*\.css.*$ [NC]
    RewriteRule ^(.*)$ subfolder/index.php/?page=$1 [L]
    </IfModule>

    <IfModule mod_rewrite.c> 
    ErrorDocument 404 /error.html
    ErrorDocument 403 /error.html
    </IfModule>

I want to set a default variable for a query that comes at the end of a url

The .htaccess file redirects the url as follows:

http://www.server.com/folder/subfolder/index.php?page="some-page-name"

displayed url

http://www.server.com/folder/some-page-name

if the page name is not set, as in:

http://www.server.com/folder/

the default would be "index". I could use php function header("location:url") but that would display the "index" part at the end if the url... that I don't want.

htacess content

   Options -Indexes

    <IfModule mod_rewrite.c>
    RewriteEngine On
    #RewriteCond %{REQUEST_URI} !^(/index\.php|/img|/js|/css|/robots\.txt|/favicon\.ico)
    RewriteBase /folder/
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !^.*\.css.*$ [NC]
    RewriteRule ^(.*)$ subfolder/index.php/?page=$1 [L]
    </IfModule>

    <IfModule mod_rewrite.c> 
    ErrorDocument 404 /error.html
    ErrorDocument 403 /error.html
    </IfModule>

您不必重定向到index.php。您可以使用类似的内容:

header('Location: /folder/front-page');

如果您只想 http://example.com/folder/ 显示您的索引页面,您可以在 PHP 脚本中使用以下内容:

$requested_page = filter_input(INPUT_GET, 'pageID');
$allowed_pages = array('some-page', 'some-page-name');
if($requested_page == ''){
   // display your index page as ?pageID is not set or empty
}
elseif(in_array($requested_page, $allowed_pages)){
   // display $requested_page
}
else{
   // display a 404 Not Found error
}

You don't have to redirect to index.php. You can use something like:

header('Location: /folder/front-page');

If you just want http://example.com/folder/ show up your index page, you could use the following in your PHP script:

$requested_page = filter_input(INPUT_GET, 'pageID');
$allowed_pages = array('some-page', 'some-page-name');
if($requested_page == ''){
   // display your index page as ?pageID is not set or empty
}
elseif(in_array($requested_page, $allowed_pages)){
   // display $requested_page
}
else{
   // display a 404 Not Found error
}

在您的 PHP 文件中尝试以下代码:

$pageID = 'index';

if(isset($_REQUEST['pageID']) && !empty($_REQUEST['pageID']))
    $pageID = get_magic_quotes_gpc() ? stripslashes($_REQUEST['pageID']) : $_REQUEST['pageID'];

// Your code should now use the $pageID variable...

这会将 $pageID 设置为默认值“index”。然后,如果 mod_rewrite 给出了不同的 PageID,则 $pageID 将设置为该值。然后,您的代码应使用 $pageID 的值。

Try this code in your PHP file:

$pageID = 'index';

if(isset($_REQUEST['pageID']) && !empty($_REQUEST['pageID']))
    $pageID = get_magic_quotes_gpc() ? stripslashes($_REQUEST['pageID']) : $_REQUEST['pageID'];

// Your code should now use the $pageID variable...

What this will do is set $pageID to a default value of "index". Then, if a different PageID is given by the mod_rewrite, $pageID will bet set to that value. Your code should then use the value of $pageID.

您的问题太长,没有阅读,但是如果您只想在 .htaccess 文件中设置一个变量并将其传递给 PHP,那么这样做很容易 -

在 .htaccess 文件中(http://httpd .apache.org/docs/2.0/mod/mod_env.html#setenv):

SetEnv default_url http://my.url/goes/here

在你的 PHP 脚本中 (http://www.php.net/manual/en/reserved.variables.environment.php):

header('Location: '. $_ENV['default_url']);

或者,如果你有 ErrorDocument 处理程序,您也许也可以简单地发送状态代码(请参阅 header() 的第三个选项,http://us.php.net/manual/en/function.header.php)。

Your question was too long, didn't read, however if you just want to set a variable in your .htaccess file and pass it to PHP it's pretty easy to do it like this -

In the .htaccess file (http://httpd.apache.org/docs/2.0/mod/mod_env.html#setenv):

SetEnv default_url http://my.url/goes/here

In your PHP script (http://www.php.net/manual/en/reserved.variables.environment.php):

header('Location: '. $_ENV['default_url']);

Alternately, if you have ErrorDocument handlers, you might be able to simply send a status code as well (see the third option to header(), http://us.php.net/manual/en/function.header.php).
