login form

[mforan]

hi there, i was wondering how on earth to make a form change its target url when a check box in the form is ticked....

heres the form code:

<form action="free/login.php" method="post" name="login_form" id="login_form">
<div align="center" class="style4">User:
<input type="text" name="user" size="12" />
<br />
Pass:
<input type="password" name="pass" size="12" />
<br />
<label>
<input name="tickbox" type="checkbox" id="tickbox" value="1" />
p2p</label>
access <br />
<br />
<input name="submit" type="submit" value="&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Login&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;" />
</div>
</form>

basically i want it so when the user ticks the box the form action changes from "free/login.php" to "login.php".

can anyone help me with the php code for this please?

thanks.

as I get it
you have two different taget pages.
- /free/login.php
- login.php

as is the action="free/login.php"
after submit will always goto /free/login.php
there is no way I know of to change this

you could have a test in beginning of free/login.php:

if ($_POST['tickbox'] == 1){
header( 'location: login.php' );
exit;
}

This would redirect to login.php
Now, when a redirect, all POST variable values are lost.
And will have to be re-entered in login.php

I think the whole idea with having a choice with a tickbox in this form
is not the best.
It would be better to make a 3rd page
where user has got two options ( 2 buttons or 2 links )
to goto either of:
- login.php
- /free/login.php
Instead of tickbox user makes his choice here, before going to login.

It's not PHP code. To do it exactly the way you're asking, you'd have to use Javascript.

My rule of thumb is never use Javascript when you can do it with PHP.

So the technique is that you post to a PHP file that checks to see if tickbox==1. If yes, then include("free/login.php"); and that code will get executed. If no, then include("login.php"); and its code will be executed.

i see what u mean halojoy!

etully, ive very new to php, how would that code be layed out? :bemused:

[etully]

You have four files. (1) A form (2) a decision script, (3) free/login.php, and (4) login.php

File #1 (with the form): <form action="decision.php">

File #2 (decision.php):
<?php if ($_POST['tickbox']==1) { include("free/login.php"); }
else { include("login.php"); } ?>

Because you're posting to decision.php, either login.php or free/login.php will get included and executed and all the values in the form will be available. Don't use the header:Location technique because, as halojoy said, you will lose all the values that were posted from the form.

well ive done that, it seems to submit the username okay, but not the password?

these errors appear in the log in phase:
Warning: Cannot modify header information - headers already sent by (output started at /home2/ambroid/public_html/checker.php:2) in /home2/ambroid/public_html/login.php on line 272

Warning: Cannot modify header information - headers already sent by (output started at /home2/ambroid/public_html/checker.php:2) in /home2/ambroid/public_html/login.php on line 273

funny how those lines in login.php are:
<?php
}
} elseif ($foundpass == $pass) {
setcookie("ambroidusername", $user);
setcookie("ambroidpassword", sha1($foundpass));
?>

cookie settings :/

[etully]

You can't set cookies after you've printed anything on the page including any text, html, print statements, or even spaces.

Just set a session variable out of the $_POST variable on the second page to save them on any other pages and there should be no problem.

[mforan]

er?

[Houdini]

$SESSION variables once set are good the entire time a user is logged into your site. So on the next page then start your script like this

<?php
session_start();
//your code here
//then set a $_POST to a $_SESSION varaible like this
$_SESSION['tick']=$_POST['tickbox']; //now $_SESSION['tick'] can be used any where
...
?>
