PHP - Session Interrupting Other Input Form.

Full Excel VBA Course - Beginner to Expert

Session Interrupting Other Input Form.	View Content

So, I have two forms..

One for displaying a submitted name.

And one for displaying an array of submitted words.

At the very top of my index.php, I have:

Code: [Select]
<?php session_start();

And only in my Second form, for displaying array of words, I've put a 'clear' button to clear the array, which works :

Code: [Select]
elseif (isset($_POST['reset'])) {
$_SESSION['words'] = '';
unset($_SESSION['words']);
session_destroy();
}

Problem:

When I've submitted a name in the First form, and then submit a word in the Second form, the name of the First form disappears!

This is also happening the other way, as well as using the reset button for the Second form.

Should I use Two Sessions? Is this possible? And how do I do it?

Thanks.

Adding Session Entity From A Html Form Input

Similar Tutorials

I am a little experienced with PHP sessions, but not totally as I haven't got my head completely around its logic yet, as your about to see.

I wonder wondering how I can go about adding a session entity from a HTML form input?
I'm guessing it will be something like:

$_POST['name'] => $_SESSION['delivery']['name'];

Then, to echo the session entity, you would simply do something like:

echo $_SESSION['delivery']['name'];

Php Session Issue With $password On Input

Similar Tutorials

I am having a very strange issue on one server. I have the same code in a development server running fine, but in my prod server it is failing. Here is the main issue:

I have a user authentication routine that accepts UserID and Password from a form and validates it against a MySQL database. So to start, UserId and Password are entered via POST variables as is standard:

$UserId=@$_POST['UserId'];
$Password=@$_POST['Password'];

The Password is encrypted using a standard crypt method such as:

$encrypt = crypt($Password,'6!68$7435!');

And this is stored in a MySQL database. This part is working fine, that is, the password is encrypted in value and stored in the MySQL database as 'epasswd'. On login, I am using session, so a standard session_start() and eventual session_destroy() on logout are used. The reason I mention this is because I suspect my issue is session related.

So normally this works well. User logs in and I check credentials as follows in one part of my auth routine:

elseif(UserAuth($UserId,$Password)){
    $UserLogin=$UserId; session_start();
    $_SESSION['UserLogin'] = $UserLogin;
    sql_insertActivity();
    header("Location: home.php");

And the auth routine is as follows:

<?

function UserAuth($UserId,$Password){
global $conn;
$Stmt="select epasswd from Users where UserId='$UserId' and Approved='1' or Approved='-1' or Approved='-2'";
$Result = mysql_query($Stmt, $conn) or die(mysql_error());
$Result=mysql_fetch_row($Result);
$epasswd=$Result[0];
$retval=($epasswd==crypt($Password,$epasswd));
return($retval);
}
?>

So I am checking for a valid UserID and Password on form input, and I have a few other variables set for approved status. The retval checks the password they enter versus the encrypted value for a match. This usually works well. Then login occurs and session started, etc.

Here is the issue. I added a quick admin routine a little while ago which helps reset a user's password to a temporary value. Once this value is set, along with a setting of approved=-1 in my database, then the user is re-directed to a Change Password screen to update his or her password. *Note: I changed the value to 'Charlie' for this discussion purpose. Here is that quick admin routine I run when I need to change a User to a temp setting:

// ----- Establish database connection -----
require "../inc_php/inc_mysql_prod.php";

//

$UserId=@$_GET['UserId'];
$Password='Charlie';
$encrypt = crypt($Password,'6!68$7435!');
$sql = "UPDATE Users set epasswd='$encrypt', approved='-1' where UserId='$UserId'";
mysql_query($sql, $conn) or die(mysql_error());

So this does work as I validate the UserID is updated in the MySQL database along with an encrypted value for 'Charlie'.

However, this is where things breakdown going forward. When the user logs in with the temp credentials, and enters in the Change password routine, their new password is saved in the table. However, when logging back in with the new credentials, the new password is not valid. And what's odd is that 'Charlie', the temp password, works for them on login and nothing else, no matter how many times they change the password in the form.

So seems a case of session management out of control? What is the issue? I am defining session on all Php pages used, and have a logout to destroy session, etc. The temp password routine is something I run as an admin in the system and it doesn't have a session start statement. And I am not defining any global vars for Password. I lloked into session management and tried some UNSET paths and such, but may not be doing this correctly. Also I did a complete stop apache, remove all php sess_ files, restart and to no avail. I tried the clear my client side cookies deal in the browser, and still the same problem.

What is odd is that this same set of code works fine on my other server, but breaks down on the mirrored server. They are essentially twins in all setup. Some minor differences between the two servers regarding PHP setup that might(?) make a difference.

DEV server:

SERVER_SOFTWARE Apache/2.2.3 (Red Hat)

PROD server: (server showing the issues):

SERVER_SOFTWARE Apache/2.2.3 (CentOS)

HTTP_COOKIE PHPSESSID=3gocr0hhelvsjjlt63pp4qlnp3

_REQUEST["PHPSESSID"] 3gocr0hhelvsjjlt63pp4qlnp3 _COOKIE["PHPSESSID"] 3gocr0hhelvsjjlt63pp4qlnp3

_SERVER["HTTP_COOKIE"] PHPSESSID=3gocr0hhelvsjjlt63pp4qlnp3

Thanks appreciate the help!

Using Session Array Input To Sql Database

I am trying to create a website that after you receive an email you have to use the email address and password to confirm account. Then the next page allows you to change your password. I want to save the users email from the first page and use it in the SQL statement in the second page to locate the user in the DB and update the data.

There must be some problem with the way I have my code logically set up. It will make it to the 2nd step but then it will go back to the main email confirmation page.

Form Input With Two Date Formats In Two Different Input Fields From Select Date

Similar Tutorials

I have a calendar select date function for my form that returns the date in the calendar format for USA: 02/16/2012. I need to have this appear as is for the form and in the db for the 'record_date' column, but I need to format this date in mysql DATE format (2012-02-16) and submit it at the same time with another column name 'new_date' in the database in a hidden input field. Is there a way to do this possibly with a temporary table or something?

Any ideas would be welcome.

Contact Form Question, Input Field Then Auto-populating On Different Form

Similar Tutorials

I have read around and can't seem to find the right coding for what I need on this forum and some other other forums.

I have a contact form (as listed below) and I need 2 locations (Print Name and Title) fields to auto-populate on a separate form (can be a doc, pdf, etc. any form of document which is easiest) and this form can be totally back end and the individual using the form never is going to see the form.

It's going on a contract form, that we would like to auto-populate.

Also is there a simple attachment code so individuals can attach documents to the code?

Using Session And Uniqid For Form

Similar Tutorials

I have a form on page 1 that submits to page 2, then on to page 3, 4 and 5. On each page more data is collected, then page 5 puts it all into its respective place in the database.

I'm trying to prevent a duplicate entry from someone hitting the back button, and I've seen suggestions to do it with sessions and a uniqid.

I'm not versed in sessions, so my first question is, because I'm not submitting to the same page, where do I put the session? on page 2 or page one?
Right now, on page one, all I have is:

Code: [Select]
<?php session_start();

include("dbconnection.php");
?>



<?php

$unique_id = uniqid (rand (),true);
  $_SESSION['unique_id']=$unique_id;
  ?>

<form name="register1" class="registration_form" method="post" action="register2test.php" target="_self" onsubmit="return myForm()">
<input type="hidden" name="unique_id" id="unique_id_form" value="<?php echo $unique_id; ?>" >
<input type="submit" value="Submit" class="buttontype"/>
</form>

on page two, I'm assuming, it's something similar to...

Code: [Select]
<?php
session_start();

if (isset($_POST["submit"]))
{
    if ($_POST["unique_id_form"] == $_SESSION["unique_id"])
    {
        $_SESSION["unique_id"] = '';
       /*set variables here ? */    }
    else
        echo 'error';
}
else
{
    $_SESSION["unique_id"] = uniqid (rand (),true);
?>

Different Session Value After Submitting Form

Similar Tutorials

I am trying to learn how to program in PHP. For a long time i was using WAMP and my localhost. When i ran into trouble i searched the web, watched videos and eventually find a solution. Trying to upload my scripts into a shared hosting web server i had some difficulties in basic things, like using $_SESSION superglobal variable. What i want to do is to use a hidden field with a value inside a form, and after submitting the form, to compare the $_SESSION variable to the $_POST variable in order to check for CSRF.

<?php

	//call all custom functions
	require_once('Custom_Functions/functions.php');

	//session must be send before HTML headers

	secure_session_start();

?>
<!DOCTYPE html>
<html lang="en">
<body>
<?php 

	if(isset($_POST['submit']))
	{
		$postvalue = $_POST['input1'];
		$sessionvalue = $_SESSION['hashed_token'];

		echo '<br />==========================<br />';
		echo '<br />AFTER PRESSING SUBMIT<br />';

		echo '<br />==========================<br />';

		echo 'Value of  $_POST["hashed_token"] = '.$postvalue.'<br />';
		echo 'Value of $_SESSION["hashed_token"] = '.$sessionvalue.'<br />';
		

	}


$hashed_token = hash('sha256', uniqid(mt_rand(), TRUE));

$_SESSION['hashed_token'] = $hashed_token;


echo '<br />==========================<br />';
echo '<br />BEFORE PRESSING SUBMIT<br />';

echo '<br />==========================<br />';


echo '<br />Value of $_SESSION["hashed_token"] = '.$hashed_token.'<br />';


?>

<form action="" method="POST">
	<input type="hidden" name="input1" value="<?php echo $hashed_token; ?>" />
	<p><input type="submit" name="submit" /></p>
</form>


</body>


</html>

In this script i have 1 custom function: a) secure_session_start()

function secure_session_start(){

	//Set a custom session name
	$session_name = 'TESTSESSID';

	ini_set('session.use_only_cookies', 1);

	ini_set('session.entropy_file', '/dev/urandom');

	
	if (in_array('sha512', hash_algos())) {
	  
	    ini_set('session.hash_function', 'sha256');
	 }

	ini_set('session.use_trans_sid', 0);

	ini_set('session.hash_bits_per_character', 5);

	ini_set('session.cookie_secure', 1);

	$secure = TRUE;

	$httponly = TRUE;


	$cookieParams = session_get_cookie_params();
	
	session_set_cookie_params($cookieParams['lifetime'], $cookieParams['path'], $cookieParams['domain'], $secure, $httponly);

	session_name($session_name);

	
	ini_set("session.save_path", "/home/SESSIONS");

	session_start();

}

The procedure goes as follows: FIRST COMMUNICATION WITH THE SERVER: The superglobal variable $_SESSION['hashed_token'] is assigned the random hash value, which is then passed to the hidden input field. I then echo it. RESULT: ==========================

BEFORE PRESSING SUBMIT

==========================

Value of $_SESSION["hashed_token"] = 93438a1b9b72085ce9430291acebdc4cfdee9d001b91a26207aebc22e04689fc SECOND COMMUNICATION WITH THE SERVER: The user press the submit button, the script then checks if the submit button is pressed, and gets in the if statement(because is TRUE). Then i collect the $_POST and $_SESSION values and echo them. New random hash is assigned to the $_SESSION superglobal variable. RESULT: ==========================

AFTER PRESSING SUBMIT

==========================
Value of $_POST["hashed_token"] = 93438a1b9b72085ce9430291acebdc4cfdee9d001b91a26207aebc22e04689fc
Value of $_SESSION["hashed_token"] = 8f176aeb3a09a1b30e0ea862c78625d7c11743da933d366cface3fa238388e57

The random hash is assigned to the $_SESSION variable, but when i try to call it after the submit is pressed its giving me a complete different value. If i remove the function secure_session_start() and just use session_start() it works: RESULT (using session_start() ) ==========================

AFTER PRESSING SUBMIT

==========================
Value of $_POST["hashed_token"] = a5eaaaa38c428af623a599e664ea9c64a2ff0674e18e9250c54e52bbc586b614
Value of $_SESSION["hashed_token"] = a5eaaaa38c428af623a599e664ea9c64a2ff0674e18e9250c54e52bbc586b614

Value of $_SESSION["hashed_token"] = e2d4acc239a747217860d71a80553abd41142dbeb8f6fafab511caff8a081fc4 Any ideas why this is happening? The problem is inside the secure_session_start() function but i cant find out why. Also, when i use the secure_session_start() function and more specifically the ini_set("session.save_path", "/home/SESSIONS"); i am forcing the session to be stored inside the /home/SESSIONS folder. But when i only use the session_start() the session i still gets stored inside that path. I checked my .htaccess and there is nothing storing the sessions in that folder. Why is that? One last thing: When using FIREBUG-->Cookies is see 2 names: the custom one (TESTSESSID) and PHPSESSID(which is the default). Shouldnt i only see the custom session name only? Thanks in advance.

Reset Session Timeout Without Submitting Form

Similar Tutorials

I have a form that is very long. Sometimes the logged-in user will spend over 20 minutes on this screen and then when they hit submit, the session has already expired and they are redirected to the login screen and anything on that form is lost.
Is there a way to reset the session timeout to zero everytime they either click the screen with the mouse, or type something into a form field (without submitting the form)? Not sure if this would only work with javascript or if there is php code that I would put in the beginning of the action.php that looks for whether the session has timed out and if so, add the form contents to the database first before logging them out? A php solution like that would be preferable to a javascript one.
But also if the sessiopn has already expired, then the action.php script would be less secure if I put the code there because then anyone not logged in could use that page so that's probably not the solution. Best solution would be to reset the session timer whenever they click ont he screen or start typing in the form.

Session Variables Lost When Form Posted

Adding Form Variables Into Session Cart

Similar Tutorials

Hi all

I have a php form as follows:

<form action="basket.php?action=add&id=1&qty=1" method="post" name="buy-product">
<input name="initial_1" id="initial_1" type="text" size="8" maxlength="1" />
<input name="initial_2" id="initial_2" type="text" size="8" maxlength="1" />
<input name="initial_3" id="initial_3" type="text" size="8" maxlength="1" />
<input name="send" type="submit" class="contact-form-button" id="send" value="Submit" />

Basically I need to add the three initials into a session so that they can be shown in the shopping cart next to the product.

How do I add the initials to the session and how do I output them to the shopping cart?

At the start of my basket.php script I have:

$cart = $_SESSION['cart'];
$action = $_GET['action'];
$id = $_GET['id'];
$qty = $_GET['qty'];
$initial_1 = $_POST['initial_1'];
$initial_2 = $_POST['initial_2'];
$initial_3 = $_POST['initial_3'];

I now need to create a table with the cart showing item, price and initials.

Cheers
Pete.

Session Variables Do Not Get Returned Into Previous Page's Form.

Similar Tutorials

This is a multi page registration form. I want to check the user input from form1.php with preg_match in form2.php then return the users details back into form1 with error messages(e.g $errname) so the user doesn't need to re enter the information.

Neither the error messages or the session variables are shown in form1.php's form. I've echoed out the session variables found that the value makes it to form 2. But the variables are empty when it goes back to form 1.

Submit A Form And Unset A Session Variable On Other Page

Similar Tutorials

Hi everyone, as the title stated, I would like to know how I could submit a form in one page(cart) and unset a session variable on other page. Right now my form is setting a variable within the page back to 0, however I would like the form to unset the session variable from other page as well. The issue with my code is that every time I attempt to clear out all items, my code can empty out the cart. But whenever I close and reopen the cart, the same content will show up again. So I need to unset the session variable. Please let me know what should I do in order to solve the problem and I greatly appreciate your help. My code is currently looking like this: cart.php

if(!empty($_GET['aID']))
{	
$aID = $_GET['aID'];
echo $aID;
if(isset($_POST['removeAll']))
{
$aID = "0";
}
$cartSQL = "SELECT * from article where aID in ($aID)";
echo "cart sql :$cartSQL";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
	$aTitle[] = $row[ 'name' ];
}
}
<form action = "" method = "POST">
<td style = "width = 200px"><input type="submit" value="Empty cart" name="removeAll"></td>
</form>

And this is the session variable from other page where I would like it to be unset upon submitting the form.

if(!empty($cartSubmit))
	$_SESSION["cartSubmit"] = $cartSubmit;
else	
	$cart = $_SESSION["cartSubmit"];

<a href="javascript:popup('cart.php?aID=<?php if(empty($cartSubmit)) echo "$cart"; else echo "$cartSubmit";?>')">Cart</a>

Need Help With Php Form Input

Similar Tutorials

Hi, everyone. I need help with a PHP project on which I'm currently working.

I need to create a form which does the following:
1) When you insert a negative number, it echoes: "Please insert a positive number."
2) When you insert a number greater than 1000, it echoes: "Please insert a number less than 1000."
3) When you insert anything else that's not a number (ie: a letter), it echoes: "Please insert a valid number."
4) If it doesn't do any of the above, it'll take the number that you entered and loop "Hello World" as many times as that number.

The code that I have so far looks something like below. (I had to type it from the top of my head.)

<?php

<form action="hwpositive.php" method="post">
Enter number: <input type="text" name="number" />
</form>

$input = $_POST["number"];

if ($input<0)
{ echo "Please insert a positive number."; }
else if ($input>1000)
{ echo "Please insert a number less than 1000."; }
else if ($input!=is_numeric)
{ echo "Please insert a valid number."; }
else {
for {$i; $i<=$_POST["number"]; $i++;}
}

?>

I can get this code to do the first three tasks listed above, but not the last. I'm a high school Programming 12 student, and this is my first year of learning PHP coding. Please help me out. Would it be better to use the case-switch option? I'm not too familiar on how to use it.

Thank you in advance! I appreciate your help greatly.
