passing variables with forms

[Jordan Boden]

Hi. I'm struggling to pass variables through various web forms.

On my first php page I have tried to use:

 
<input type="hidden" name="email" value="<$php $_POST["email"]; print "$email"; ?>" />
 
 

I am passing four variables from my first html page to the first php page. From here I want to pass the variables to another html page and then finally to the last php page.

So basically the process is as follows:

details.html > details.php > payment_details.html > payment_details.php

On the final php page(payment_details.php I plan to use the php mail() function to email the variables to a customer and echo a confirmation message to the customer telling them of the details being sent but I can't seem to find a way of passing the variables through continuous pages.

Any feedback would be much appreciated.

Thanks,

Jordan

<input type="hidden" name="email" value="<$php $_POST["email"]; print "$email"; ?>" />
 

in this line there is something strange. lets break your line like below and see what we have

<input type="hidden" name="email" value="<$php
 $_POST["email"]; 
 print "$email"; 
?>" />
 

now take a closer look line 2 is doing nothing. on line 3 you are printing $email I believe this is empty.

you better try this on line 2

$email=$_POST['email'];
 

then print. you might reach somewhere.

Thanks for the reply johny10151981 much appreciated but that didn't seem to work either

You should consider using sessions.

[Jordan Boden]

In what way would I use sessions JKing? would I use sessions for each variable name?

[JKing]

To store and pass your variables. It is a common practice when dealing with shopping carts or ecommerce sites. A session is temporary data stored on the server that can be accessed throughout the life of the session and is available to all pages.

Google php sessions. Several tutorials should come up. Have a read through them as I am sure they will explain them better and with more depth than I would.

[Jordan Boden]

I've figured out how to use sessions however I am having problems putting the variables into the php mail function.

 
<?php
 
session_start();
 
print $_SESSION['email'];
print "<br />";
print $_SESSION['seatnumber'];
print "<br />";
print $_SESSION['time'];
print "<br />";
print $_SESSION['rideselection'];
 
$to= $_POST['email'];
$subject="Ticket Confirmation";
$message="Thank you for booking with us.\n\nYou have chose to ride: $rideselection\n\nSeatnumber: $seatnumber\n\n At: $time";
$from="[e-mail]";
$headers="From: [e-mail]";
mail($to,$subject,$message,$headers);

Your variables are empty, by the looks of your code. Your variables are $_SESSION['rideselection'], not $rideselection.

The best thing to do would be to:

$rideselection = $_SESSION['rideselection'];

And so on, for all your session variables before you insert them into the message part of your email.

Also, you're putting your variables within a string, which wont work. Change your $message= to:

$message="Thank you for booking with us.\n\nYou have chose to ride: " . $rideselection . "\n\nSeatnumber: " . $seatnumber . "\n\n At: " . $time;

When dealing with $_SESSION and $_POST variables, the bracketed name ['name'] is an associative array name. The ['name'] is the identifier of the array item. Where as $_POST['name'] is the variable. Not $name.

$name is completely separate from $_POST['name'] as mentioned above. Instead of doing this:

$name = $_POST['name'];
print $name;

Save some overhead and simply do:

print $_POST['name'];

Where as, the easier way to do this:

$message="Thank you for booking with us.\n\nYou have chose to ride: $rideselection\n\nSeatnumber: $seatnumber\n\n At: $time";

Try:

$message="Thank you for booking with us.\n\nYou have chose to ride: ". $rideselection ."\n\nSeatnumber: ". $seatnumber. "\n\n At: ". $time;

This line seperates the string from the variables, making it easier to read in an editor (atleast one with the color coding)

Thanks guys for your help it worked! The only problem I have now is when the user submits the details a message saying "Message delivery failed..." appears even though an email is sent with the appropriate details which is confusing. Here is my code...

 
$to="\nE-Mail is: ".$email;
$subject="Ticket Confirmation";
$message="Thank you for booking with us.\n\nYou have chose to ride: ".$rideselection. "\n\nSeatnumber: ".$seatnumber. "\n\n At: ".$time;
$from="[e-mail]";
$headers="From: [e-mail]";
 
mail($to,$subject,$message,$from,$headers);
 
 
if (mail($to,$subject,$message,$from,$headers))
 
    {
 
           echo("Message successfully sent!");
 
    }
 
  else
 
      {
 
           echo("Message delivery failed...");
 
      }
 
 

That is my code and everything is in working order as when I submit my own details for testing purposes, an e-mail is sent to my email server yet I get the error message saying "Message delivery failed..."

Your sending two mails?
After looking at PHP.net's function reference. Your parameters are incorrect.

bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]]
