[SOLVED] why doesn't this work? (form/session/if/else statement)(well-explained!)(easycod

[dsaba]

this is driving me nuts, i've been at it for hours

basically the rundown of what i'm trying to do is this:

1. i generate a random code and store that code in a session

2. i have an html form that asks for that code

3. there is an if/else statement that display success statements if you type in the correct code or if you didn't type in the correct code

 

here is the code (the parent brackets are the ones that are farthest out, its better if you paste this code into a php editor to see the if/else statement more clearly)(sorry thats how I tab if/else statements)

 

<?php
session_start();
/////////////////////////////////////////////////////
srand((double)microtime()*1000000); 
$randomnumber = md5(rand(0,9999)); 
$code = substr($randomnumber, 17, 5);
$_SESSION['code'] = $code;
//////////////////////////////////////////////////////

$field = $_POST['field'];
$field_func = "hello";

/////////////////////////////////////////////////////////////////////////////////////////
if ($field != "")										{
if ($field == $_SESSION['code'])				{
if ($field_func == "hello")	{
echo "function = true";
echo '<br>';
echo "Entered: ";
echo $field;
echo '<br>';
echo "Session was: ";
echo $_SESSION['code'];
						}
else						{
echo "function = false";
echo '<br>';
echo "Entered: ";
echo $field;
echo '<br>';
echo "Session was: ";
echo $_SESSION['code'];
						}
											}
elseif ($field != $_SESSION['code'])			{
echo "field does not equal the session";
											}
													}
else													{
echo "Type in this code: ";
echo $_SESSION['code'];
echo '<br>';
echo '<form name="whatever" method="POST" action="new.php"><input name="field" type="text" class="form-field" size="30" maxlength="15" /><input type="submit" name="Submit" value="Submit" /></form>';
													}









?>

############THE PROBLEM##########

No matter if you type the correct code in it always shows "field does not equal the session"

this is apparently not true!, please help - thanks

First question (Which may or not have any effect) before I look at the rest...where is $field defined?

 

Because unless you do:

 

<?php

$field = $_POST['field'];

?>

 

...You're asuming that register_globals is enabled wherever the script is running.

[dsaba]

field is defined in the code i posted -the one that actually contains TEXT

 

the picture is just of the if/else statement, so look at the scrollbar code to see everything

[SammyGunnz]

Never mind. I see that the above reference.

 

However, the code looks kinda cluttered and you have echo's everywhere for me to put forth any effort to look through it. Good luck :-P

[dsaba]

i figured it out, when I send the form information to the page it reloads it and hence erases the past session and makes a new one, so the code does not match

[dsaba]

thanks for the help dsaba! you da man!

[dsaba]

no problem
