code explaintion

$main=getTemplate("main");
eval ("\$index= \"".$main."\";");

What is getTemplate? and what is eval?

[Mordecai]

getTemplate() is a user defined function. I'm assuming it gets a template, but I don't know, since I haven't seen the code for it.
eval() will evaluate the text inside as PHP code.

If you look in the manual, you could read about these functions.

in the install.php program, I have the following codes,

if ($_GET['step']==4){

if(!$set[1]) {$set[1]='admin';}
if(!$set[2]) {$set[2]='test';}

$set2=MD5('set[2]');

$filecontent="<? //write config to a file

\$adminidL='$set[1]';
\$adminpwdL='$set[2]';

\$title='$set[3]';
\$picpath='$set[4]';
";

writetofile("config.php",$filecontent);

$body.="config finish<br><br>";
$step="<a href=admin.php>success and enter admin</a>";
}

Then I go to the admin.php and I want to use $adminidL
and $adminpwdL which I input when run install.php.

Why I can not pass this two variable to the following code????

<?
/*

*/
//session_name('s');
//session_start();

$time_s=time();
$admin_body='';

require_once("global.php");
$pictime=get_date($time_s);

if (empty($adminid)) $adminid=$HTTP_SESSION_VARS['adminid'];
if (empty($adminpwd)) $adminpwd=$HTTP_SESSION_VARS['adminpwd'];

if($adminid != $adminidL || MD5('$adminpwd') != $adminpwdL)

{
FORM action=admin.php method=post>
<P>Administration Log in</P>
<P>Username:</SPAN><INPUT type=text name=adminid></P>
<P>Password:</SPAN><INPUT type=password name=adminpwd></P>
<P></P>
<P><INPUT type=submit value=Admin Login>&nbsp;&nbsp;<input type=reset value=reenter></P></FORM></TD></TR></TBODY></TABLE><BR>
";

}

what i see is that the variables you want are written in a file called config.php. If you write

include ("config.php");

you should have these variables available.

<?
/*

*/
//session_name('s');
//session_start();
include ("config.php");
$time_s=time();
$admin_body='';

require_once("global.php");
$pictime=get_date($time_s);

include ("config.php"); <=======I got the variable, true! thanks
echo $adminidL;
echo $adminpwdL;

if (empty($adminid)) $adminid=$HTTP_SESSION_VARS['adminid'];
if (empty($adminpwd)) $adminpwd=$HTTP_SESSION_VARS['adminpwd'];

if($adminid != $adminidL || MD5('$adminpwd') != $adminpwdL) {$admin_body="

<TABLE id=AutoNumber2 style=\"BORDER-COLLAPSE: collapse\" borderColor=#c0c0c0 cellSpacing=20 cellPadding=0 width=100% align=center border=1>
<TBODY>
<TR>
<TD width=100%>
<FORM action=admin.php method=post>
<P>Administration Log in</P>
<P>Username:</SPAN><INPUT type=text name=adminid></P>
<P>Password:</SPAN><INPUT type=password name=adminpwd></P>
<P></P>
<P><INPUT type=submit value=Admin Login>&nbsp;&nbsp;<input type=reset value=reenter></P></FORM></TD></TR></TBODY></TABLE><BR>
";

**************** but the login checking still not workable
after I entered passwd/username , it always just reset the login form...never pass...

if($adminid != $adminidL || MD5('$adminpwd') != $adminpwdL)

any of these conditions are false. echo the variables and check it. There must be a reasonable explanation. Also post the else statement that goes after that condition
