Hide div element on custom url - html

Question

I'm looking for a solution to hide div element with php code base on my different custom link. So that the div i want to hide is not appeared in html source.
I have two different "div"s in a single page. In order to make the page showing div A and hiding div B, i have created "example.com/account/?Member=login"(for showing div A while div b is not showing) and "example.com/account/?Member=Signup"(for showing div B while div A is not appear). But, the code what i'm using now is as stated below.
Code in my css:
.login {display:none;}
.signup {display:none;}
PHP on html file:
<?
$s=$_GET['Member'];
if ($s=="Login") {
echo ('<style>.login {display:block;}</style>');
}
?>
<?
$s=$_GET['Member'];
if ($s=="Signup") {
echo ('<style>.signup {display:block;}</style>');
}
?>
<div class="login">
<p>Login Form</p>
</div><!--login-->
<div class="signup">
<p>Signup Form</p>
</div><!--signup-->
With this method, both div are showing in html source, even though one of the div is not showing in web page.
I want the div to be hidden without showing in html code. Any solution?

Answer 1

Why not just only render the login on your conditions matching. i.e.
<? $s=$_GET['Member'];
if ($s!="Login") { ?>
<div class="login">
<p>Login Form</p>
</div><!--login-->
<?php } else {?>
<div class="signup">
<p>Signup Form</p>
</div><!--signup-->
<? } ?>
The above assume you want to show one of the two possibilities, you'd need to change it to
<? $s=$_GET['Member'];
if ($s=="Login") { ?>
<div class="login">
<p>Login Form</p>
</div><!--login-->
<? }
$s=$_GET['Member'];
if ($s=="Signup") { ?>
<div class="signup">
<p>Signup Form</p>
</div><!--signup-->
<? } ?>
if there is a posibility of showing none of them

Clear you css and:
<?
$s=$_GET['Member'];
if ($s=="Login") {
?>
<div class="login">
<p>Login Form</p>
</div><!--login-->
<?
}
$s=$_GET['Member'];
if ($s=="Signup") {
?>
<div class="signup">
<p>Signup Form</p>
</div><!--signup-->
<?
}
?>
