This article mainly introduces the method of judging whether a user is logged in by phpcms v9, which has a certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Phpcms v9 determines whether the user is logged in? Phpcms V9 how to determine whether a user logs in or not and the problem of label writing after login

The first step is to get the userid

{php$userid=param::get_cookie ('_ userid');}

Then determine whether it is empty or not.

{if $userid}. The code after login is written here. {else} . The code after login is written here. {/ if}

Got it.

If you want to extend more functions, such as the ability to view contact information after login, we need to declare a variable to control the return page after login.

$forward = trim ($url)

Code when not logged in

Log in to view contact information

Note that there should be a parameter forward= {urlencode ($url)} in the link address so that the user can successfully return to the previous content page after logging in.

Complete code

{php$userid=param::get_cookie ('_ userid'); $forward=trim ($url);} {if$userid}

Content after login

{else}

Log in to view contact information

{/ if}

But if we want to achieve it on the home page, it won't work with this method, because the home page is static, we can do it by writing a method.

Open / phpcms/modules/content/index.php add

/ / Home user logs in to publicfunctionmember () {$_ username=param::get_cookie ('_ username'); $_ userid=param::get_cookie ('_ userid'); $siteid=isset ($_ GET ['siteid'])? intval ($_ GET [' siteid']):''; / / defines the site id constant if (! defined ('SITEID')) {define (' SITEID',$siteid);} $snda_enable=pc_base::load_config ('system','snda_enable') Includetemplate ('member','afterlogin');}

The method name can be defined according to the actual situation. Then increase the location that needs to be displayed on the home page template

< script type="text/javascript">

[xss_clean] ('

< iframe src="{APP_PATH}index.php?m=content&c=index&a=member&forward='+encodeURIComponent(location.href)+'&siteid={get_siteid()}" allowTransparency="true" width="125" height="98" frameborder="0" scrolling="no">

< /iframe>

')

< /script>
