Sessions

Dylan86

Hi! I know that you have to register variables to be in the session...

lets say i do

session_register("variable");

could i ... in a later page just go

echo $variable

and would it have saved the info into the session??

Now for my big question..

How do i get something to send the entire session to my email...

i know how to send mail... but how would i get it to send the session??

or better yet... lets say i wanted it to detect wether the variable is there... and then turn it into a hidden field... would that work?

(plz nothing about MySQL or databases... im gonna learn soon.. but for now, i wanna try without)

any suggestions please?

Firstly, as of the later versions of php, you don't have to register your session variables. Make sure that on the start of each page that you need to use the session variables, at the start of your script you have the line:

session_start();

Then, when you need to set your session variables, just use:

$_SESSION['variable_name'] = "value";

When you need to refer to those variables later on, use (for example):

echo "Welcome to my website, ".$_SESSION['username'];

Sessions really aren't that daunting. Just make sure you initialize the session on each page you need the variables, and you should be fine! 🙂

how could i set the value to a variable.. THEY have to set it.. right? so why would i put that value in the code??

Dylan86

would this work?:

<?php
session_start();
if ($name) {
$SESSION['name'] = "$name";
}
if ($company) {
$SESSION['company'] = "$company";
}
if ($title) {
$SESSION['title'] = "$title";
}
if ($email) {
$SESSION['email'] = "$email";
}
if ($telephone) {
$SESSION['telephone'] = "$telephone";
}
if ($fax) {
$SESSION['fax'] = "$fax";
}
if ($address) {
$SESSION['address'] = "$address";
}
if ($city) {
$SESSION['city'] = "$city";
}
if ($province) {
$SESSION['province'] = "$province";
}
if ($postalcode) {
$SESSION['postalcode'] = "$postalcode";
}
?>

Dylan86

also... can i go like this?(to check if they entered anything.. and if they did, then display it):

if ($postalcode) {
echo "Postal Code: ".$_SESSION['postalcode']."<br>";
}

or do i have to go like this.

if ($SESSION['postalcode']) {
echo "Postal Code: ".$SESSION['postalcode']."<br>";
}

The stuff in your first post would work fine 🙂

The second example you gave in your last post is the one you'll have to do

If its at all possible to get just one variable with all that an using a switch will make code look neater but will process faster for you.
Maybe Try an array.
