Question
Your task is to read and write data coming from and HTML form (provided) into either a cookie or into a session. A radio button in the HTML form is used to indicate which data store is to be used. The point the of labs is to practice with reading and writing out of these different data stores, and learn how they can be used to share data between page loads.
On each page load, do the following:
Does a form need to be processed (did someone post information to me)?
If so, process it into either the cookie or a session.
Is there data already in the session?
If so you need to print it out.
Is there data in a cookie?
Is so you need to print it out.
<?php
# First thing you need to do it start the session, this should alwasy be done first.
session_start();
# Next, get whatever is currently in the session so you can spit out on the page
$session_data = $_SESSION;
# Next, get whatever is currently in the cookies so you can spit out on the page
$cookie_data = $_COOKIE;
# Next, you need to see if the form has posted data to this page
if(!empty($_POST)){
# Now you need to check to see if the check boxes are checked
if($_POST['save_in_session'] == 1){
# If you got this far, then you need to save the rest of the form data into the session
}
if($_POST['save_cookie'] == 1){
# If you got this far, then you need to save the rest of the form data into cookies
}
}
# Now that you have saved what you needed to, spit it out on the session and cookie data below.
# There are already placeholders for the data.

Explanation / Answer
#below approach will be better choice
<?php
# First thing you need to do it start the session, this should alwasy be done first.
session_start();
# Next, get whatever is currently in the session so you can spit out on the page
$session_data = $_SESSION;
# Next, get whatever is currently in the cookies so you can spit out on the page
$cookie_data = $_COOKIE;
# Next, you need to see if the form has posted data to this page
if(!empty($_POST)){
# Now you need to check to see if the check boxes are checked
if($_POST['save_in_session'] == 1){
# If you got this far, then you need to save the rest of the form data into the session
$_SESSION['name'] = $_POST['name'];
$_SESSION['street'] = $_POST['street'];
$_SESSION['city'] = $_POST['city'];
$_SESSION['state'] = $_POST['state'];
$_SESSION['zip'] = $_POST['zip'];
$_SESSION['phone'] = $_POST['phone'];
$_SESSION['email'] = $_POST['email'];
}
if($_POST['save_cookie'] == 1){
# If you got this far, then you need to save the rest of the form data into cookies
# best way is to use - setCookieData($_POST);
$_COOKIE['name'] = $_POST['name'];
$_COOKIE['street'] = $_POST['street'];
$_COOKIE['city'] = $_POST['city'];
$_COOKIE['state'] = $_POST['state'];
$_COOKIE['zip'] = $_POST['zip'];
$_COOKIE['phone'] = $_POST['phone'];
$_COOKIE['email'] = $_POST['email'];
}
}
# Now that you have saved what you needed to, spit it out on the session and cookie data below.
# show all cookies using for each look
if(count($_SESSION) > 0) {
echo "<div>";
echo "<h2>Information in Session</h2>";
echo "<table border='0' width=''>";
foreach ($_SESSION as $key=>$val)
{
echo "<tr><td>".$key."</td><td>".$val."</td></tr> "
}
echo "</table>";
echo "</div>";
}
# show all cookies using for each look
if(count($_COOKIE) > 0) {
echo "<div>";
echo "<h2>Information in Cookies</h2>";
echo "<table border='0' width=''>";
foreach ($_COOKIE as $key=>$val)
{
echo "<tr><td>".$key."</td><td>".$val."</td></tr> ";
