How to prevent direct accessing a particular page?

[don11]

Hello,

I  want to prevent this page from being directly accessed by all via just putting its address in the address bar:

http://www.mysite.com/page1/page2/signup.php

 

I want to allow to be accessed this page only via clicking on a link in a particular page like:

http://www.mysite.com/activate/index.php

 

Please help me.

You can either use the rather simple way, of redirecting the user from the page.

// Places after sessions, but before all the other code.
header("Location: ../index.php");
exit; // stop page execution

 

Else you can use .htaccess, to redirect user

Thank you for quick reply.

I have to put  this

<php>// Places after sessions, but before all the other code.header("Location: ../index.php");exit; // stop page execution</php>

in http://www.mysite.com/page1/page2/signup.php ?

Yes, it'll redirect the user to index.php ^^

If you want users just to click on a link on index page to access the sign up page you can simply do this:

 

Add a link to the index page. The link should be:  http://www.mysite.com/page1/page2/signup.php?do=activate

Then add this to the top of the sign up page:

if(!isset($_GET['do']))

{

//Redirect to index page

}

else

{

//show contents of page

 

}

header("Location: ../index.php");exit; 

Above code is redirecting even from index page.

 

Add a link to the index page. The link should be:  http://www.mysite.com/page1/page2/signup.php?do=activate


Then add this to the top of the sign up page: 
if(!isset($_GET['do']))
{
header("Location: ../index.php");
}
else
{
//show contents of page

}

This code is also redirecting even from index page.

just an idea...

 

index page

start sessions

create var1 random number 1

store var1 in sessions

create link using ?myvar=var1

 

2nd page

start sessioins

check to see if session var AND get var (1) are both set (2) both integers (3) equal each other -

if not redirect

else display page

header("Location: ../index.php");
}

{
//show contents of page

The code should work. It is pretty simple and clear. May be there is any typo while you wrote the code. Just check it once again. :-)
