[PHP] header(Location:blah...) - passing variables

2001-12-04 Thread Lee Philip Reilly 

Hi,

I wonder if someone could tell me whether or not the following is
possible?

I have an HTML form which passes a username and password to a PHP script
for validation. If either is not valid, I would like it to return to the
previous page - carrying with it a variable plus the submitted form
information...

=-=-=-=-=-=-=-=-=
if (strlen ($password1) 4 ) {
   $err = Password must be more than 4 characters long;
   header(Location:http://somelocation.php;);
   // ^-- at the location, the $err and form variables will be available

   exit;
}
=-=-=-=-=-=-=-=-=

Is it possible to this without using an HTML form?

Thanks very much in advance.

- Best regards,

Lee

There are many different ways to do this ...

1. Have the same PHP script that validates generate the login page. 
This way the script always has the correct data and you don't need to 
pass anything.

2. Header(Location: login.php?err=$erruser=$userpass=$pass);
This will work, but the bad password will be visible in the query string.

3. Start a session at the login page and register the variables you 
need to use on the login page.

2001-12-04 Thread Valentin V. Petruchek 

Set the form receiver to $PHP_SELF. When data is posted (use $HTPP_POST_VARS
to check if is) check it for correctness. If everything is ok, use
Header(Location: work_for_authorized.php) otherwise show the current (i.e.
login page) with $user, $pass available...

RE: [PHP] header(Location:blah...) - passing variables

2001-12-04 Thread Mark Charette 

I cheat and just include the original form on error ...

Almost all my input values are set to PHP variables in the form. The 1st
time through none are set, so the values are blank. After submitting the
form, I check for validity. If there are errors I mark the errors, generate
an error string, and include the form. That way all previously typed in data
remains in the form without me having to tell the user to hit the back
button, and there's no horribly long URL string resetting all those values.

There's a bit more work than that (using htmlspecialchars et al.) but if you
start creating forms with error checking  indication in mind it's really
easy to do validation and redisplay if necessary.

RE: [PHP] header(Location:blah...) - passing variables

2001-12-04 Thread Richard S. Crawford 

My approach has been to pass an error code back to the original form.

form.php:
?php
 print(form aciton=\formVerify.php\);
 print(a buncha form crap);
 if ($errcode==1) print (Your user id is wrong. You suck);
 if ($errcode==2) print (Your password is wrong. You really suck);
 print(/form);
?


Then in formVerify.php:

?php
 ...error checking code...
 if (userID invalid)
 header(Location: form.php?errcode=1);
 if (password invalid)
 header(Location: form.php?errcode=2);
 else
 header(Location: goodpage.php);
?

You could probably also use cookies to pass the error code back and forth, 
but that's probably overkill and unreliable.

(Sorry if the pseudo-code I used above offends anyone with the use of the 
word suck; the futile job search has got me really annoyed right now.)

RE: [PHP] header(Location:blah...) - passing variables

2001-12-04 Thread Dan McCullough 

It has been my idea to make a function, and pass the fields, then register a global 
feedback var
and then check one by one each required field, or what ever you are trying to verify 
in the
fields. 
function formCheck ($username,$password,$smellycat) { 
global $feedback, $username, $password;
if (!$username) {
$feedback .= Yo!  This ain't right ... fix it!;
return false;
}
blah blah blah ...

I'd recommend urlencoding those variables if you're going to do it that 
way, otherwise you may get some non-sense characters resulting in a bad URL.

Re: [PHP] header(Location:blah...) - passing variables

2001-12-04 Thread Miles Thompson 

In a revised scheme for a customer I'm doing # 3.

User can come into any page, a bit of PHP at the top does this:
starts session
registers origin
assigns PHP_SELF to $origin
checks to see if another session var is set and directs to logon page if not
if( !session_is_registered( member_id ) ) { header(Location: 
logon.php\n)};

Where they are logged on and member_id is set. There's nothing magic 
about member_id, it's simply a token and has no content. After 
authentication the user is returned, via a header command, like so:
header(Location: $origin);

If authentication fails they loop on the logon page, which has links to 
a  registration and lost my password  forms.

The neatest part of this is that any page can be protected from 
unauthorized viewing merely adding a bout 6 lines of code at the top and 
saving it with a php rather than html extension.

Hi,

I have an HTML form which passes a username and password to a PHP script
for validation. If either is not valid, I would like it to return to the
previous page - carrying with it a variable plus the submitted form
information...

=-=-=-=-=-=-=-=-=
if (strlen ($password1) 4 ) {
$err = Password must be more than 4 characters long;
header(Location:http://somelocation.php;);
// ^-- at the location, the $err and form variables will be available

exit;
}

Is it possible to this without using an HTML form?

Thanks very much in advance.
