[SOLVED] Passing Variables

UbH · January 9, 2008

Let me dive right in.

[sTEP ONE]

I have a form with about 20+ items for a user to fill out.

Upon hitting submit my PHP script gets called. "nominationSubmit.php"

[sTEP TWO]

With this script I create a directory on the web server based on the "first" and "last" name fields the user filled out on the previous forms page.

[sTEP THREE]<PROBLEM BEGINS

Then I redirect them to another PHP/HTML forms page via meta tag that allows them to upload up to 5 files to this newly created directory on the web server, again by referencing variables from our first forms page.

[sTEP FOUR]<PROBLEM CONTINUES

After they have browsed for their files to upload and hit submit I take them to a third PHP script that uploads and moves the files to their proper locations & build an email

message with URLs of the new uploaded files to be send to me in this email as well. Again all by referencing variables from our first forms page.

All the scripts are working when going straight from the first forms page over to a single php script (removing the uploading process of course)

But dividing all the scripts into these 4 steps I get no variable passing beyond the second step.

How do I pass the variables that get assigned from the first forms page over to my last steps??

Use sessions and save $_POST as session.

session_start(); in top of the three last pages

in the two last pages you change $_POST with $_SESSION

and as the last thing in the second file you put

<?php
foreach($_POST as $n => $v)
  $_SESSION[$n] = $v;
?>

This just tell you a simple way to do it, you should try include some type of security.

This just tell you a simple way to do it, you should try include some type of security.

In order to ensure security, just make sure that you've validated all fields before saving them into sessions, and each time you call the session variable, make sure the value fits and it hasn't been manipulated (IE: use mysql_real_escape_string(), stripslashes(), addslashes(), etc...) to make sure what's being passed could not in any way damage your website.

In theory it ain't possible to manipulate the sessions. Their stored at the server, and just a session id is stored as Cookie.

But the userinput is the securityproblem.

Yes, in theory, but nothing is ever impossible. If there ain't a way, someone will find a way (Murphy's Law). I would remain on the safe side, it takes up what, an extra 5 or 6 lines to re-validate each time?

Right off the bat I got these two errors..

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /mnt/w0209/d31/s33/b02c2dec/www/counselor_of_the_year/nominationSubmit.php: in /mnt/w0209/d31/s33/b02c2dec//www/somewebsite.com/somelocation/anotherlocation/counselor_of_the_year/nominationSubmit.php on line 9

Here is my code for my first nominationSubmit.php script... what am I doing wrong?

Yeah, sure what you're telling

Google quote_smart and use that function

<?php
foreach($_POST as $n => $v)
  $_SESSION[$n] = quote_smart($v);
?>

UbH: Session start has to be the first thing in the document.. So you have to put <?php session_start(); ?> before the HTML-code

GingerRobot · January 9, 2008

what am I doing wrong?

The call to session_start(); must be sent before any headers. Headers will get sent with the first output to the browser - so the call to the function must be called before any output. In other words, move the session_start() function above everything else including the document type definition.

and GingerRobot

I have it working now.. email gets sent with veriables intact.

I only need help with one more thing.

I would like to have a function to check to see if a person/folder has been created on the web server, so in my first nominationSubmit.php script I have just wrote this but its not working.. where would you guys suggest I to fix?

//Directory Creation Checking
$newDir = 'submissions/2008_2009/$cFirstName$cLastName';



		//Create New Submissions Folder
		if ($newDir = 0)
		{
			mkdir("submissions/2008_2009/$cFirstName$cLastName");	
		}
		else 
		{
			echo "Sorry this person has already been nominated";
		}

GingerRobot · January 9, 2008

Try:

//Directory Creation Checking
$newDir = 'submissions/2008_2009/$cFirstName$cLastName';
//Create New Submissions Folder
if (!is_dir($newDir))
{
mkdir("submissions/2008_2009/$cFirstName$cLastName");	
}
else 
{
echo "Sorry this person has already been nominated";
}

Norsk.Firefox · January 9, 2008

It wont work, variables don't work inside single quotes

Try:

<?php
//Directory Creation Checking
$newDir = is_dir('submissions/2008_2009/'. strlower($cFirstName .$cLastName));

//Create New Submissions Folder
if ($newDir == false)
{
mkdir("submissions/2008_2009/". strtolower($cFirstName$cLastName));	
}
else 
{
echo "Sorry this person has already been nominated";
}
?>

UbH · January 9, 2008

Herm..

GingerRobots Version I get this error is folder has already been created.

Warning: mkdir() [function.mkdir]: File exists in /mnt/w0209/d31/s33/b02c2dec/www/somewebsite.com/somelocation/anotherlocation/counselor_of_the_year/nominationSubmit.php on line 42

Norsk.Firefox Version I get this error regardless if a user has been created before or not.

Parse error: syntax error, unexpected T_VARIABLE in /mnt/w0209/d31/s33/b02c2dec/www/somewebsite.com/somelocation/anotherlocation/counselor_of_the_year/nominationSubmit.php on line 43

drummer101 · January 9, 2008

change

mkdir("submissions/2008_2009/". strtolower($cFirstName$cLastName));

to

mkdir("submissions/2008_2009/". strtolower($cFirstName . $cLastName));

UbH · January 9, 2008

Here is what I have changed the code too..

//Directory Creation Checking
$newDir = is_dir('submissions/2008_2009/'. strlower($cFirstName .$cLastName));

//Create New Submissions Folder
if ($newDir == false)
{
mkdir("submissions/2008_2009/". strtolower($cFirstName . $cLastName));	
}
else 
{
echo "Sorry this person has already been nominated";
}

But I am still getting an error regardless if a directory is already created or not.

Fatal error: Call to undefined function strlower() in /mnt/w0209/d31/s33/b02c2dec/www/somewebsite.com/somelocation/anotherlocation/counselor_of_the_year/nominationSubmit.php on line 38

UbH · January 10, 2008

Is anyone able to help me with this?

Its the last part I need to call this project complete.

Thanks everyone for helping me so far!!

drummer101 · January 10, 2008

... strlower($cFirstName .$cLastName));

the function is strtolower()

change that line to

$newDir = is_dir('submissions/2008_2009/'. strtolower($cFirstName . $cLastName));

GingerRobot · January 10, 2008

It needs to be strtolower():

//Directory Creation Checking
$newDir = is_dir('submissions/2008_2009/'. strtolower($cFirstName .$cLastName));

//Create New Submissions Folder
if ($newDir == false)
{
mkdir("submissions/2008_2009/". strtolower($cFirstName . $cLastName));	
}
else 
{
echo "Sorry this person has already been nominated";
}

UbH · January 10, 2008

Excellent its working now..

Just one more little thing if I may ask.

How do I redirect a person to the previous page or stop the meta tag redirect if the $newDir has already been created and echo's "Sorry this person has already been nominated"?

I tried

//Directory Creation Checking
$newDir = is_dir('submissions/2008_2009/'. strtolower($cFirstName .$cLastName));

//Create New Submissions Folder
if ($newDir == false)
{
mkdir("submissions/2008_2009/". strtolower($cFirstName . $cLastName));
header( 'Location: http://www.somewebsite.com/nextstep.php' ) ;
}
else 
{
echo "Sorry this person has already been nominated";
        header( 'Location: http://www.somewebsite.com/thepreviousepage.html' ) ;
}

with and also without the meta tag at the top

<meta HTTP-EQUIV="REFRESH" content="2; url=nextstep.php">

but all I got was this error:

Warning: Cannot modify header information - headers already sent by (output started at /mnt/w0209/d31/s33/b02c2dec/www/somewebsite.com/somepage/anotherpage/counselor_of_the_year/nominationSubmit.php:9) in /mnt/w0209/d31/s33/b02c2dec/www/somewebsite.com/somepage/anotherpage/counselor_of_the_year/nominationSubmit.php on line 49

Thank you ALL for helping me this far I couldn't have done it with out you guys!!!

drummer101 · January 10, 2008

You can't send any HTML or whitespace before you send the headers, IE. all your PHP processing needs to be taken care of before you pass HTML.

(although you can do ob_start() to hold the page request and process everything and send it all at once. It will fix the problem, but not the code.)

UbH · January 10, 2008

Herm as my title says on the site n00bie, I will have to say HUH?

see whats happening is that if the user recives the message "Sorry this person has already been nominated" it still directs them to my third step "The File Uploading Process" instead of shutting down the whole process.

From what you are telling me is that I cant do a conditional shut down if they receive the "Sorry this person has already been nominated" message??

If the ob_start() will solve this solution can you provide me with a conditional example of how to use this??

I learn best from example and appreciate all the help you guys have provided so far I have learned a great deal!!

Thanks

UbH

UbH · January 11, 2008

Got it!!

Put it in my first line like this:

<?php session_start();
  ob_start();
?>

And The Rest like this:

//Directory Creation Checking
$newDir = is_dir('submissions/2008_2009/'. strtolower($Their_First_Name .$Their_Last_Name));

//Create New Submissions Folder
if ($newDir == false)
{
mkdir("submissions/2008_2009/". strtolower($Their_First_Name . $Their_Last_Name));
header("refresh:0; url='uploadSubmit.php'");	
}
else 
{	

echo "Sorry this person has already been nominated";
header("refresh:0; url='index.html'");
}

Works like a charm!

Thanks drummer101

drummer101 · January 11, 2008

You're welcome, in the future, try to design your pages so that ALL php is processed BEFORE you even get to <html><head></head> etc...

And you'll remove the problem all together.

ob_start() is a cheap lazy work around.

UbH · January 11, 2008

LESSON LEARNED!!!

drummer101 I know you are form helper and have a lot to do but do you think you could help me with one other thing?

I created a new topic for it cause this one was getting WAY OFF topic.
