Topic awaiting preservation: PHP Session ... (Page 1 of 1)

Hello,
I want to pass email and password value from Form1 to Form2 with session so I am using
<input type="hidden" name="<?=session_name() ?>" value="<?=session_id() ?>">

and in the Form2 I am just simply putting the value..

$sql = "INSERT INTO tutor ( email, pswd ) VALUES ( '$email', '$password' )";

what is wrong I am doing ?
will you suggest me please?

shalvi: I suspect you are going to have to give us more information as what you have given us didn't make any sense.

If you are using a session then you don't need to pass the data between forms using a hidden form as the point of sessions is that they hold information like this so it can be used across pages.

I'm not sure where the session_name() and session_id() fucntions come in or how the 2 bits of code are connected.

If you could expand on your question(s) we might be able to help you better.

Shavi,

I don't understand why you are storing the values in Form elements if they are already in Session. Anyway, to get the values from Session you should use the following syntax

$email = $_SESSION["email"];
$password = $_SESSION["password"];

If you want to get the values submitted from a Form using POST method you would use the following syntax

$email = $_POST["email"];
$password = $_POST["password"];

if using GET method

$email = $_GET["email"];
$password = $_GET["password"];


Hope this helps

Uh, as far as I can tell he's not passing anything by a hidden except for the session ID so it can be continued on the next page. This is an accepted way of handling sessions in PHP. You can pass the session ID and session name by POST, GET or cookie. I prefer the cookie method personally.

hello,
thanx for your help...now my code appears below...still i can't get the value of email and password in page2.php....
maybe there's a silly mistake i am doing...


//page1.php


<INPUT class=text id=email maxLength=100 size=37 name=email>
<input type="password" class="text" name="password" id="password" size="37" maxlength="100" >

<?php
session_start();
$_SESSION['email'] = $email;//email is the form value
$_SESSION['password'] = $password;//password is the form value
?>

//page2.php

<?php
session_start();
$email = $_SESSION['email'];
$password = $_SESSION['password'];
$sql = "INSERT INTO tutor ( email, pswd ) VALUES ( '$email', '$password' )";

Well for one thing you don't have a submit button your your form, so it can't do anything with it, plus the fact you're trying to load values out of the $_POST array on the same page as putting them into it...that won't work. On page two where you use $_SESSION is where you should be using $_POST

Skaarjj: Good point - it was too early and the post and me weren't making sense.

That said you could still get into problems doing things like that.

shalvi: Could I refer you to the manual:
http://www.php.net/manual/en/ref.session.php

Basically Skaarjj's answer is right - you don't need to start the session on page1 and you get the info through the POST (how you do that depends on the version of PHP you are using).

well what i am trying to do is....get the email address and password in Form1(page1.php) then it goes to the Form2 ..and there user will provide user details like name,address,phone no etc..then in the Form2 after submission page3.php will add the information in the database....

<FORM name=registrationform //This is submission of Form1
onsubmit="return validateForm(this)"
action="page2.php "method=post>

then page2.php will get user details and...

<FORM name=registrationform
onsubmit="return validateForm(this)"
action=page3.php method=post>

so i need to carry that email and password from page1.php to page3.php....

as i am a newbie in PHP may be this a silly mistake...but can't make it work

n/m

I misread that last post....

First you need to get the values that have been submitted. As Skaarjj had written, you should be using $_POST to retrieve the values on page2.php.

For example:

$password = $_POST["password"];
$email = $_POST["email"];

This is what should be used to retrieve the values that have been submitted. You can then put those values into hidden fields if you choose or store them into session.

I Think you are confusing how server-side PHP works as opposed to client side.

This:

<INPUT class=text id=email maxLength=100 size=37 name=email>
<input type="password" class="text" name="password" id="password" size="37" maxlength="100" >

<?php
session_start();
$_SESSION['email'] = $email;//email is the form value
$_SESSION['password'] = $password;//password is the form value
?>

Will not get the form values into your session variables. All PHP is done before the HTML gets to the browser. In page 1 all you need is the raw form, no PHP.

In Page 2 you want to add the variables to the session and you want to get those variables from 1 of 3 arrays $_POST, $_GET or $_REQUEST (which is $_GET and $_POST combined)

so in page 2 you want

$_SESSION['email'] = $_REQUEST['email'];
$_SESSION['password'] = $_REQUEST['password'];


Now in page 3 you will be able to access $_SESSION['email'] and $_SESSION['password']

In this case you really don't need sessions, a couple of hidden input fields would work fine. Especially since you are creating a temporary form on page 2 where you will need to put the values from page 1.
