Real-time calling of user login status on static pages using js + php

This article mainly introduces how to call the user's logon status in real time on static pages using js + php. The php page is called using js on a static page to realize the real-time call function of the user's logon status, for more information, see

 

 

This article describes how to call the user's logon status in real time on static pages through js + php. Share it with you for your reference. The specific analysis is as follows:

During program development, pages are often made into static html forms, which can reduce server load. However, when a registered user logs in, to display the logon success or logon prompt on the html page, we must find another method to implement it. Below we will use js + php for an instance, of course, ajax can also be implemented. The Code is as follows:

The Code is as follows:

<! Doctype html public "-// w3c // dtd xhtml 1.0 transitional // en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
<Html xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Meta http-equiv = "content-type" content = "text/html; charset = gb2312"/>
<Title> real-time calling of user login and exit login programs on static pages (php code called for webpage special effects) </title>
</Head>

<Body>
<Script language = "javascript" src = "/loginajax. php? Fid = {fid} "> </script>
</Body>
</Html>


The loginajax. php file, because loginajax. php is called and output in the form of js, the code in this file can be correctly displayed in the form of js output. The Code is as follows:

The Code is as follows:

<? Php
$ Id = isset ($ _ get ['fid'])? $ _ Get ['fid']: 0;
If (! Isset ($ _ cookie ['vvg ']) {
?>
Document. write ('user name: <input type = "text" class = "pl_sty1" name = "username" id = "username"/> ');
Document. write ('<input name = "action" type = "hidden" value = "login"/> ');
<? Php
}
Else
{
Echo 'document. write ('['. $ _ cookie ['realname'], '] statement <a href =/login. php? Action = logout> exit </a> ');';
}
?>
