PHP ordering form help please. variables staying the same after submit

timmykins02 · December 15, 2011

So I'm making an ordering form for pizza, and it works fine and im using two separate pages: 1- display the form where the user can select the pizza, and 2-display the order and the price, and user can go back and edit

the problem im having is when i got back from the 2nd page to the 1st page, to edit the data, I want the variables to stay the same. For example, if the user selected a medium cheese pizza, i want the values of cheese and pizza to still be there, so the user doesnt have to fill the entire form out again.

ive done this before, but now when i try it doesn''t work and Ive tried everything. Thanks in advance

If the code is needed, I'll post it here

Hello Timmy,

I would recommend the use of sessions. Use session_start() on both pages. When the user submits the first page, on page 2, you should register the user inputs.

For example: on page 2 should be something like this:

<?php 

session_start();
$_SESSION['ORDER'] = $_POST['ORDER'];
$_SESSION['PTYPE'] = $_POST['PTYPE'];
$_SESSION['DTYPE'] = $_POST['DTYPE'];
$_SESSION['PSIZE'] = $_POST['PSIZE'];
$_SESSION['DSIZE'] = $_POST['DSIZE'];
$_SESSION['PTYPE2'] = $_POST['PTYPE2'];
$_SESSION['DTYPE2'] = $_POST['DTYPE2'];
$_SESSION['PSIZE2'] = $_POST['PSIZE2'];
$_SESSION['DSIZE2'] = $_POST['DSIZE2'];
$_SESSION['PTYPE3'] = $_POST['PTYPE3'];
$_SESSION['DTYPE3'] = $_POST['DTYPE3'];
$_SESSION['PSIZE3'] = $_POST['PSIZE3'];
$_SESSION['DSIZE3'] = $_POST['DSIZE3'];
// And etc... for all those user inputs.  

?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<title>Title of the document</title>
<meta name="description" content="Type a Short Description Here" />
<meta name="keywords" content="type, keywords, here" />
<meta name="author" content="Your Name" />
<meta http-equiv="content-type" content="text/html;charset=UTF-8" /> 
<link rel="stylesheet" type="text/css" href="mystyle.css" />
</head>
... etc....

Then on your first page, you would have something like this:

<?php 
if(isset($_SESSION['PTYPE'])){
if ($_SESSION['PTYPE'] == 'no pizza') {
$NOPIZZA='selected' ;
}elseif ($_SESSION['PTYPE'] == 'cheese') {
$CHEESE='selected' ;
}elseif ($_SESSION['PTYPE'] =='pepporoni') {
$PEPPORONI='selected' ;
}elseif ($_SESSION['PTYPE']=='veggie') {
$VEGGIE='selected' ;
}elseif ($_SESSION['PTYPE'] =='meat lovers') {
$MEAT='selected' ;
}
}
echo"<br/>Pizza: <select name='PTYPE'>\n";
echo"<option></option>";
echo"<option $NOPIZZA>no pizza</option>";
echo"<option $CHEESE>cheese</option>";
echo"<option $PEPPORONI>pepporoni</option>";
echo"<option $VEGGIE>veggie</option>";
echo"<option $MEAT>meat lovers</option>";
echo"</select> ";

That's just an overview of what can be done.

PFMaBiSmAd · December 15, 2011

You can make a copy of the entire $_POST array using one statement -

$_SESSION['post_data'] = $_POST;

You would reference each value like - $_SESSION['post_data']['ORDER'] or you can simply copy the values from the session variable back to the $_POST array - $_POST = $_SESSION['post_data'];

jotorres1 · December 15, 2011

It can also be done that way, then extract all the post variables:

On second page would be:

$_SESSION['post_data'] = $_POST;

On first page you can extract:

if(isset($_SESSION['post_data'])) {extract($_SESSION['post_data'];}

And then refer to all the variables directly; $PTYPE, $ORDER etc..

xyph · December 15, 2011

If you're going to use sessions to transfer form data around, you should group it in such a way that the data is unique to that form, and that series of requests.

Sessions will propagate over multiple tabs/windows. If someone visits the same or a similar form in another tab that uses $_SESSION['post_data'], the data from the original form may get changed.

I tried this but still doesnt work. It keeps on saying

Notice: Undefined variable: DEL in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 77

Notice: Undefined variable: TAKE in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 78

Notice: Undefined variable: EAT in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 79

Notice: Undefined variable: CHEESE in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 95

and i used print_r ($REQUEST) to see all of the variables and they are all kept when I go from page 2 to the first page, and with the use of my IF statement, $DEL should become selected, but it doesnt, and the variable is said to be undefined. Im new to php and i dont understand why it isnt working, ive done it before this way. Please help me. the part of the code is

if(isset($_SESSION['ORDER'])){
if ($_SESSION['ORDER'] == 'delivery') {
$DEL='selected' ;
}elseif ($_SESSION['ORDER'] == 'takeout') {
$TAKE='selected' ;
}elseif ($_SESSION['ORDER'] =='eatin') {
$EAT='selected' ;
}
}



echo"Delivery <input type='radio' name='ORDER' value='delivery' $DEL> \n";
echo"Take Out <input type='radio' name='ORDER' value='takeout' $TAKE> \n";
echo"Eat in <input type='radio' name='ORDER' value='eatin' $EAT> \n";

jotorres1 · December 16, 2011

Need to make sure they are set:

<?php 
echo"Delivery <input type='radio' name='ORDER' value='delivery' <?php if(isset($DEL)){echo $DEL;?>> \n";
echo"Take Out <input type='radio' name='ORDER' value='takeout' <?php if(isset($TAKE)){echo $TAKE;?>> \n";
echo"Eat in <input type='radio' name='ORDER' value='eatin' <?php if(isset($EAT)){echo $EAT;?>> \n";
?>

timmykins02 · December 16, 2011

Need to make sure they are set:

<?php 
echo"Delivery <input type='radio' name='ORDER' value='delivery' <?php if(isset($DEL)){echo $DEL;?>> \n";
echo"Take Out <input type='radio' name='ORDER' value='takeout' <?php if(isset($TAKE)){echo $TAKE;?>> \n";
echo"Eat in <input type='radio' name='ORDER' value='eatin' <?php if(isset($EAT)){echo $EAT;?>> \n";
?>

I tried that but i still get the notices of

Notice: Undefined variable: DEL in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 75

Notice: Undefined variable: TAKE in C:\Program Files\EasyPHP-5.3.6.1\www\Project\project.php on line 79

Can someone please help? This is very important and I need this done quickly. Sorry for being so needy. Can someone just look at my codes quickly and make a quick fix?

The problem is that when I go back to the first page, the variables dont say put. For example, if I checked "delivery" for the order type, it doesn't stay checked when I go back to that page.

Here are the codes. Code 1

<?php

print_r ($_REQUEST) ;

if(isset($_POST['ORDER'])) {
$ORDER = $_POST['ORDER'];
}
if(isset($_POST['PTYPE'])) {
$PTYPE = $_POST['PTYPE'];
}
if(isset($_POST['DTYPE'])) {
$DTYPE = $_POST['DTYPE'];
}
if(isset($_POST['PSIZE'])) {
$PSIZE = $_POST['PSIZE'];
}
if(isset($_POST['DSIZE'])) {
$DSIZE = $_POST['DSIZE'];
}
if(isset($_POST['PTYPE2'])) {
$PTYPE2 = $_POST['PTYPE2'];
}
if(isset($_POST['DTYPE2'])) {
$DTYPE2 = $_POST['DTYPE2'];
}
if(isset($_POST['PSIZE2'])) {
$PSIZE2 = $_POST['PSIZE2'];
}
if(isset($_POST['DSIZE2'])) {
$DSIZE2 = $_POST['DSIZE2'];
}
if(isset($_POST['PTYPE3'])) {
$PTYPE3 = $_POST['PTYPE3'];
}
if(isset($_POST['DTYPE3'])) {
$DTYPE3 = $_POST['DTYPE3'];
}
if(isset($_POST['PSIZE3'])) {
$PSIZE3 = $_POST['PSIZE3'];
}
if(isset($_POST['DSIZE3'])) {
$DSIZE3 = $_POST['DSIZE3'];
}



echo "Order Type: <br/> \n";
echo"<form method='post' action='project2.php'>";


if(isset($_SESSION['ORDER'])){
if ($_SESSION['ORDER'] == 'delivery') {
$DEL='selected' ;
}elseif ($_SESSION['ORDER'] == 'takeout') {
$TAKE='selected' ;
}elseif ($_SESSION['ORDER'] =='eatin') {
$EAT='selected' ;
}
}



echo"Delivery <input type='radio' name='ORDER' value='delivery' $DEL>"  ;
if(isset($DEL)){
echo $DEL;
}
echo"Take Out <input type='radio' name='ORDER' value='takeout' $TAKE>"   ;
if(isset($TAKE)){
echo $TAKE;  
} 
echo"Eat in <input type='radio' name='ORDER' value='eatin' $EAT>" ;
if(isset($EAT)){
echo $EAT;
}
if(isset($_SESSION['PTYPE'])){
if ($_SESSION['PTYPE'] == 'no pizza') {
$NOPIZZA='selected' ;
}elseif ($_SESSION['PTYPE'] == 'cheese') {
$CHEESE='selected' ;
}elseif ($_SESSION['PTYPE'] =='pepporoni') {

}elseif ($_SESSION['PTYPE']=='veggie') {

}elseif ($_SESSION['PTYPE'] =='meat lovers') {

}
}

I know its really messy ive been trying a lot of diffferent things.

$_SESSION['DTYPE2'] = $_POST['DTYPE2'];
$_SESSION['PSIZE2'] = $_POST['PSIZE2'];
$_SESSION['DSIZE2'] = $_POST['DSIZE2'];
$_SESSION['PTYPE3'] = $_POST['PTYPE3'];
$_SESSION['DTYPE3'] = $_POST['DTYPE3'];
$_SESSION['PSIZE3'] = $_POST['PSIZE3'];
$_SESSION['DSIZE3'] = $_POST['DSIZE3'];



$ORDER = $_POST['ORDER'];
$PTYPE = $_POST['PTYPE'];

timmykins02 · December 19, 2011

the errors went away but it still doesn't work. It recognizes all the variables, but the IF statement doesn't seem to work. Is there anything i need to do to the second page? I need to know this soon please help.

jcbones · December 19, 2011

Run some de-bugging, at the top of the page put this>

change

print_r ($_REQUEST) ;

To

echo '<pre>' . print_r($_SESSION,true) . '</pre>';

Then post the script with the output.

timmykins02 · December 20, 2011

ok well i got this at the top of the page:

Array

(

[post_data] => Array

(

)

[ORDER] => delivery

[PTYPE] => cheese

[DTYPE] => Bottled Fanta

[PSIZE] => Small

[DSIZE] => 2 liter

[PTYPE2] => pepporoni

[DTYPE2] => Bottled Fanta

[PSIZE2] => Medium

[DSIZE2] => 1 liter

[PTYPE3] => pepporoni

[DTYPE3] => Bottled Sprite

[PSIZE3] => Medium

[DSIZE3] => 1 liter

)

and the code i put was this

<?php



session_start();  //start session;
$_SESSION['post_data'] = $_POST; //store all post data to the session array.

echo '<pre>' . print_r($_SESSION,true) . '</pre>';

/*if(isset($_POST['ORDER'])) {

echo"</select> \n";

and then it continues for the rest of the form but I haven't written the IF statements yet because I want to make sure the first ones work before I try the rest

kleb · December 20, 2011

start your session first with session_start()

use session_register()..it will save you alot of time..just use it with $_POST['whatever']..i mean

session_register($_POST['whatever']);

it should work

timmykins02 · December 20, 2011

so what do i replace with session_register($_POST['whatever']); ?

kleb · December 20, 2011

instead of using $_SESSION['order']=$_POST['order']

you will just use session_register in place of $_SESSION['order']so you it will take the values and put it on the client side even if you switch off your system it will still be there

timmykins02 · December 20, 2011

Can you give me an example please? I still don't get where I put it. :confused: can you paste it in the code so I know what to do?

Sorry if I sound kinda stupid

jcbones · December 20, 2011

session_register

Warning

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

I wouldn't do that.

1. You already have the POST data in your SESSION array, as is evident with that print_r.

2. This is because you already have called session_start();

So, now you need to make sure you have session_start at the top of EACH page that you want to use these variables. They will reside inside the same variables as long as the session is started.

I can help you, but I need the form flow. As in the start of the order, flowing to the end of the order. Otherwise, I could just give you snippets all day without ever getting it to work right.

timmykins02 · December 21, 2011

If I post the code can you just tell me how to fix it please? I honestly have no clue why it doesnt work.

Fully commented up. There are ways to tighten it up a bit, I'll let you work on that.

timmykins02 · January 7, 2012

Thank you so much I really appreciate it. The only thing is that I'm not very good at PHP and I don't understand a lot of the things. Would it be possible to just change code around slightly in order to make it work? It's not that important if its effecient and neat, I haven't learned any of that stuff yet in the class I am currently taken.

I apologize for asking you once again to work, and I completely understand if you don't want to. Thank you once again.
