[RESOLVED] order form

paldo

Hallo everybody

I have written a simple order form (order.html). When filled in, the values are posted to order.php. When clicked on the confirm button the value are sent to my email adress.

My question is: how to post the variables from the order.php to the confirm.php?

Somebody can help me?

If with php it's not possible, what other script language do I have to use?

See at: http://www.paolinet.info/test_order/order_form.html

<body>
<p>
<input type="text" name="quantity1" value="0" onfocus="if(this.value=='0')this.value=''" size="5" />
item1
</p>
<p>
<input type="text" name="quantity2" value="0" onfocus="if(this.value=='0')this.value=''" size="5" />
item2
</p>
<p>
<input type="text" name="quantity3" value="0" onfocus="if(this.value=='0')this.value=''" size="5" />
item3</p>
<input type="submit" name="submit" value="order" />
</body>
</html>

Here the script:

<?php  



$quantity1 = $_POST['quantity1'];
$quantity2 = $_POST['quantity2'];
$quantity3 = $_POST['quantity3'];

if ($_POST['quantity1'] != 0) {
print "you ordered $quantity1 item1 <br />";
}
if ($_POST['quantity2'] != 0) {
print "you ordered $quantity2 item2 <br />";
}
if ($_POST['quantity3'] != 0) {
print "you ordered $quantity3 item3 <br />";
}


?>

<input type="submit" name="submit" value="  I confirm my order" onClick="location.href='confirm.php'">



<a href="order_form.html"></a>

<input type="submit" name="submit" value="  I change my order" onClick="location.href='order_form.html'">

Here the confirm script:

<?php

$quantity1 = $_POST['quantity1'];
$quantity2 = $_POST['quantity2'];
$quantity2 = $_POST['quantity3'];

$subject ="order";


if ($_POST['quantity1'] != 0) {
$headers .= "you ordered $quantity1 item1 \n";
}
if ($_POST['quantity2'] != 0) {
$headers .= "you ordered $quantity2 item2 \n";
}
if ($_POST['quantity3'] != 0) {
$headers .= "you ordered $quantity3 item3 \n";
}




mail('xy@myadress.com',$subject,$headers);

 print "Thanks for your order."

?>

Thanks for your help

1.) you need to use the form html code to build forms.
<form method="post" action="somewhere">
...
...
</form>

2.) on the order.php page you can save the quantities in $_SESSION variable. if you started the session on the top of the page with session_start()

$_SESSION["q1"]=$_POST["quantity1"];
$_SESSION["q2"]=$_POST["quantity2"];
$_SESSION["q3"]=$_POST["quantity3"];

then ask the "are you sure" question...

if that set as YES, the quantities on the next page available:

$_SESSION["q1"]  , $_SESSION["q2"] ,$_SESSION["q3]

You should see how to send a mail using the mail() , becouse your syntax is wrong. you should not take the message into the °$headers

Dear Djjjozsi

nice learning with your help. You open me up to the world of $_session that I've never heard about.

First of all I change the order form:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Untitled Document</title>
</head>

<body>
<p>
<form action="order.php" method="POST">
  <input type="text" name="quantity1" value="0" onfocus="if(this.value=='0')this.value=''" size="5" /> 
  item1
  </p>
<p>
  <input type="text" name="quantity2" value="0" onfocus="if(this.value=='0')this.value=''" size="5" /> 
  item2
</p>
<p>
  <input type="text" name="quantity3" value="0" onfocus="if(this.value=='0')this.value=''" size="5" /> 
  item3</p>
<input type="submit" name="submit" value="order" />
</form>
</body>
</html>

Then I tried to insert the session variables:

<?php
session_start();

$_SESSION['quantity1'] = $_POST['quantity1'];
$_SESSION['quantity2'] = $_POST['quantity2'];
$_SESSION['quantity3'] = $_POST['quantity3'];
?>
<?php

$quantity1 = $_POST['quantity1'];
$quantity2 = $_POST['quantity2'];
$quantity3 = $_POST['quantity3'];

if ($_POST['quantity1'] != 0) {
print "you ordered $quantity1 item1 <br />";
}
if ($_POST['quantity2'] != 0) {
print "you ordered $quantity2 item2 <br />";
}
if ($_POST['quantity3'] != 0) {
print "you ordered $quantity3 item3 <br />";
}


?>

<input type="submit" name="submit" value="  I confirm my order" onClick="location.href='confirm.php'">



<a href="order_form.html"></a>

<input type="submit" name="submit" value="  I change my order" onClick="location.href='order_form.html'">

On the next script (confirm.php) the variables ( quantity1,quantity2, quantity3) are not passed. Just for an example I use the print function to check if the variables are available.

<?php
session_start();

$_SESSION['q1'] = $_POST['quantity1'];
$_SESSION["q2"] = $_POST['quantity2'];
$_SESSION["q3"] = $_POST['quantity3'];

?>

<?php
print "$quantity1 item1.";
print "$quantity2 item2.";
print "$quantity3 item3.";

 print "Thanks."

?>

Where is the mistake?

Thanks for your suggestions.

djjjozsi

what's happening? on page 1 you ask quantities. On second page you save them into session variables. Ask a question Yes or No.
Then on page 3 you reach the session variables, but $_POST are disappeared, so you should not give session values with them. Start the session, and use its values.

with a little change:

<?php
session_start();

$quantity1=$_SESSION["quantity1"];
$quantity2=$_SESSION["quantity2"];
$quantity3=$_SESSION["quantity3"];

print "$quantity1 item1.";
print "$quantity2 item2.";
print "$quantity3 item3.";

print "Thanks."

?>

Dear djjjozsi

many thanks for your great help. Now with this small example I got to known a bit to the session functions. On the internet I have found many explanations but little examples.
I have change the confirm.php script and reached my goal. Thanks again, it is nice to have people like you on the web.

<?php
session_start();

$quantity1=$_SESSION["quantity1"];
$quantity2=$_SESSION["quantity2"];
$quantity3=$_SESSION["quantity3"];

$subject ="order";

$headers .="$quantity1 item1.\n";
$headers .="$quantity2 item2.\n";
$headers .="$quantity3 item3.\n";

mail('myname@gmail.com',$subject,$headers);

print "Thanks."

?>

djjjozsi

this code is good for start, but needed to have further steps to make it better.

send the mail if at least one quantity has a value:

if(!empty($_SESSION["q1"]) OR !empty($_SESSION["q2"]) OR !empty($_SESSION["q3"]))
{
//send the mail, and print the message you want.

//set 0 values into quantities after sending the mail...
$_SESSION["q1"]=0;
$_SESSION["q2"]=0;
$_SESSION["q3"]=0;
}
else
die("You did not selected at least one item<br />");

Notice that in your code $header and $subject are undefined, they're a part of a correct mail() sending.

Watch the example #4 on the manual: mail()

Thanks again, it is nice to have people like you on the web.

I'm sure that on this forum there are helpful people only 🙂

And don't forget to set this thread as resolved, please.

Dear djjjozsi

I made some corrections and improvements to the script. Everything is working fine, but I still like to have your opinion. Thank you very much.

Hello,

in my opinion is you should solve the order.php without $HTTP_POST_VARS which is an out-to date technique, and unavailable since PHP 6.

Lets use a variable if you know that it has a value, i suggest that always use the

!empty($variable)
then do something(save it)

if(isset($_POST["variable"]))
save it...

in your programs. $_SESSION index has a value, check it before use it. These things makes your programming technique better.

Lets try to press refresh on the last page, your email will be sent once. Redirect the user with header("Location: somewhere.html");

In your next program, try to build these programs in one file. Try to build functions for the repeated events.

Dear djjjozsi

I have another question concerning the script: if I submit the order, and return to the order_form.html because I want to change my order, the value on the text field are zero again. How to force the browser to keep the value that where previously entered ?

Thanks for hints and tips.

djjjozsi

if you make a form dinamically with php from the session variables.
you need to save the quantities into session variables from the $POST superglobal. And you should make order_form.php instead of order_form.html, to be able to re-write the previously selected values.

<?php
session_start();
echo "<form name=\"aaaa\" method=\"post\"  action=\"order_confirm.php\">";
echo 'q1<input name="quantity1" type="text" value="'.    (!empty($_SESSION["quantity1"]) ? htmlspecialchars($_SESSION["quantity1"]):"" ).'"><br />'."\n";
echo 'q2<input name="quantity2" type="text" value="'.    (!empty($_SESSION["quantity2"]) ? htmlspecialchars($_SESSION["quantity2"]):"" ).'"><br />'."\n";
echo 'q3<input name="quantity3" type="text" value="'.    (!empty($_SESSION["quantity3"]) ? htmlspecialchars($_SESSION["quantity3"]):"" ).'"><br />'."\n";
echo '<input name="submit" type="submit" value="submit">';
print '</form>'; 

?>

Dear djjjozsi, you have found a solution to all my php problems.
I have open another thread ( parse drop down value with superglobal ) as I want to handle the same example with a drop down menu.
