how to limit access to page 'B' from page 'A'?

Anon

with header()?

i want to insure access TO index.php comes FROM login.php since variables are sent from one to the other. as it is now, a person could just type in the actual URL of index.php and go directly to the page.

TIA,

You can just look at the variable $HTTP_REFERER and use an if clause.
if ($HTTP_REFERER="someurl) give em the page
else redirect them elsewhere

Anon

not all browsers will set that though, is there another way on top of this?

How about....
I assume that you are using a form to pass variables from the login page to the index page. You can include a hidden variable type in your form with a value of whatever, "howdy". Then use an IF statement on the index page to check that the passed variable does equal "howdy".

<?php
secretpasssword="howdy";
<form action="index.php3" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" age="age"><br>
<input type="hidden" name=$secretpassword><br>
<input type="submit">
</form>

Please excuse syntax errors, i'm doing this from memory, not at my regular computer, but you get the idea....

sorry, the 'hidden' variable should have a different name, in this case "secretvar", then have an IF on the index page to check if $secretvar does equal "howdy"

<?php
secretpasssword="howdy";
<form action="index.php3" method="post">
Name: <input type="text" name="name"><br>
Age: <input type="text" age="age"><br>
<input type="hidden" secretvar=$secretpassword><br>
<input type="submit">
</form>

great idea, that worked.

thanks for the help.

figure the HTTP_REFERER and hidden password will suffice.

thanks,
