php switch

[ohdang888]

ready for a confusing problem! (at least for me  )

 

i have a form with action="do.php?do=register" method="POST"

 

i know for a fact that the do.php file is getting the $_GEt attibute correctly because i did this to error check:

if($_GET['do'] == "register"){

echo "gahhh";

}

 

and it echoed gahhh.

 

Now, i have a big-a$# switch statement with $_GET['do'] as the parameter.

 

in it i have this:

case "register":
r("?reg=confirm");
break;

default:
header(Location: index.php?m=undefined&do=".$_GET['do']);
break;

 

Get this: its redirecting me to "index.php?m=undefined&do="

 

I never reset a $_GET param or anything like that, but it seems as though its erased $_GET['do']. How messed up is that!

 

Any ideas how to solve that?

[steviez]

not sure if it will solve it but

header(Location: index.php?m=undefined&do=".$_GET['do']);

 

Should be

header("Location: index.php?m=undefined&do=".$_GET['do']);

header(Location: index.php?m=undefined&do=".$_GET['do']);

 

Should be

header("Location: index.php?m=undefined&do=".$_GET['do']);

 

 

 

Nope that was a just a typo on my part.

would be easier if you posted your whole code.

Also, could be if your using $do somewhere and register globals is on that it's overwriting it.

heres the file. thanks

<?php
require_once('connect.php');

function r($url){
header('Location: '.$url);
die();
}

function pass($pass){
return md5("$39".md5($pass)."*)dP~");
}

   {
      $isValid = false;
   }
   else
   {
      $domain = substr($email, $atIndex+1);
      $local = substr($email, 0, $atIndex);
      $localLen = strlen($local);
      $domainLen = strlen($domain);
      if ($localLen < 1 || $localLen > 64)
      {
         // local part length exceeded
         $isValid = false;
      }
      else if ($domainLen < 1 || $domainLen > 255)

see this thread which I've given the solution

http://www.phpfreaks.com/forums/index.php/topic,299702.0.html

 

I would think the solution is the same

form action should not contain ?do=register

instead just use do.php in form action

and then use

<input type="hidden" name="do" value="register"/>

retrieve the value with $_POST["do"]

 

[ohdang888]

just tried it. and same redirection.

 

then i added this before the switch statement:

if($_POST['do'] == "register"){
echo "gahhhhhhhhhhhh";
}

And guess what! IT FREIKING ECHOS gahhhhhhhhhhhh

 

i know the variable in the switch statement is right (and set), and the "case" is right... so WTF!

 

gah. any other ideas?!

[PFMaBiSmAd]

Your code in the 'register' section is redirecting back to that same page upon an error, but is not setting do= in the URL.

 

Is there some reason you have so many redirects in that code instead of just displaying the information you want?

Ya, do.php is a backend file that has functions that are done and then the user is sent back to the index.php page with the results.

 

I set it up this way cause i thought it'd be nice to have all those types of functions in one folder rather than make like 10 extra files

What do you expect the script to do ?

 

Ok, now that you are sure that you get the $_POST['do'] contain register before the switch.

For the redirect to work, you need to comment the echo ?

[ohdang888]

you need to comment the echo

 

Ya i already did that. Its back to the file thats posted (except $_GET is now $_POST)

[riwan]

you need to separate two type of things.

for redirection you need method get, so you must include ?do=register

but for form submit with method POST do not include ?do=register in the action but set it as hidden field

 

Basically you need to store the value in $_POST['do'] to $doit

if its empty then you need to store $_GET['do'] to $doit

 

So what's the problem you're having now ?

I already had all this done, yet revised it a tad and now its working. Still does not make ANY sense to me but whatever.

 

Thanks!
