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.
Real-time calling of user login and exit login programs for static pages (php tutorial code called for special webpage effects)
<! 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 = "webpage effects" src = "/loginajax. php? Fid = {fid} "> </script>
</Body>
</Html>
Loginajax. php file code
<! -- {Because loginajax. php calls the output in js format, the code in this file can be correctly displayed only in js output format .} -->
<? 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"/> ');
<?
}
Else
{
Echo 'document. write ('['. $ _ cookie ['realname'], '] statement <a href =/login. php? Action = logout> exit </a> ');';
}
?>
