php $_Post difficulty

gtsown · September 5, 2007

Hello everyone,

I'm a bit of a newbie/intermediate at php and i'm trying to figure out $_Post, while using it on an e-commerce site. Nothing too advance, just a system that works with gateway processor. I've created the form and setup connections to the gateway. As of right now, the gateway processor is pre made and cannot customize their fields. However, there are two fields which anything can be pass into, ($email_header and $email_footer)

I'm sure someone knows how to do this.

I basically want to call one of the input fields that is entered on the form and pass that info into the header variable.

for example i tried using the birth field:

$birthdate = $_POST['birth'];

$email_header="Name: " . $birthdate . "<br>";

Nothing happens except when i receive the email confirm, i get: Name: br.

here is the code i've been working on...

thank you in advance..

<?php
    //Gateway connection information
    $account="0000000000";
    $service_type_code="000000000000";
    $connecting_site_code="0000000000000";
    //Transaction ID - for tracking on your end
    $transaction_id="3435";
    //Description of the Charge
    $transaction_desc="Continuing Education Transaction";
    //How much to charge the card
    $charge_amount="0";
    //Your CGI Script that receives the response from gateway processor  
    $post_back_url='http://www.post_back_url.php';    
    //Should customer receive a Credit Card Charge receipt via email?  
    $email_ind="TRUE";  
    //Should a person on staff that get copies of the Credit Card Charge receipt via email?
    $merchant_email_ind="TRUE";  
    //Person on staff that gets copies of the Credit Card Charge receipt via email
    $merchant_email="unknown@thisemail.com";
    //Header of the Credit Card Charge receipt
    
    $birthdate = $_POST['birth'];
    $email_header="Name: " . $birthdate . "<br>";
    
    //Footer of the Credit Card Charge receipt  
    $email_footer="Test Site";  
    
    //Variables to determine how the page displays
    //CSS Setup
    $FormFormat="horizontal2";
    $HeaderHtmlPaymentForm= "<img src=http://img_src.gif width=697 height=154 alt=udeworld logo/> <h1>Payment Section</h1>";
    $FooterHtmlPaymentForm="<p> Please be patient. If you click the submit button more than once, you will be charged again. <br /><br /><br /></p>";

Before setting the $birthdate variable, do "print_r($_POST);" and see if it is a key in the array.

gtsown · September 5, 2007

I do get a return; Array() is posted on the page and 1 is sent through the email.

the $email_header is picking up a $_Post value.

Now how do i get to read an input from on the fields?

thank you in advance for you help.

lemmin · September 5, 2007

If only "Array()" is printed out, that means that the array is empty. Since I don't see any obvious mistakes, my guess is that the action on your form is pointing to a different location than you think it is. I am not familia with ssl, but I would assume you can't use the https protocal to a relative location of a file. Try just "processatgateway.php" for the action.

gtsown · September 5, 2007

The form is being submitted to the gateway processor.

All i need is to have the fields which are not declared as a variable by the processor be processed in the $email_header.

I don't need any of the info posted onto another page.

I just don't understand why the name="birth" in the input field wouldn't be read or processed once its is declared.

$email_header in the return email is reading whatever "string" in place into it.

Don't if I'm explaining this correctly..

lemmin · September 5, 2007

The reason it is printing "Name: br" is because $_POST[] doesn't contain 'birth', which you are asking it for. This goes back to my previous post, did you try what I suggested?

tippy_102 · September 5, 2007

If I'm reading this correcty, this stuff:

$birthdate = $_POST['birth'];

$email_header="Name: " . $birthdate . "<br>";

has to go in the file called processatgateway.php

gtsown · September 6, 2007

it is going to another file, but that file is controlled by the gateway processor. I don't have access to that file. If i had access to that file then i would have no problem. Fields such as Name, City, are already being collected in the processor, processed and sent to the user as a confirmation. I'm trying to call some of the fields that are not initialized by the processor into $email_header.

it feels like I'm not explaining this right. so here is the actual setup.

here's what the site looks like: http://www.udeworld.com/education/form.php

you have to enter an email address for the form to go the credit card payment.

use this information when you reach the credit card purchaser: Visa - 4007000000027 and any expiration date.

the email which is sent to you leaves out a few of the fields, those fields because the gateway processor customizable are not being sent in the email. Those fields from the form could technically be parsed into the $email_header variable. Maybe i have to identify what fields by using some sort of php code.

thanks for your responses...

For you to use the variables from the page you don't have access to, it has to send them to your page, which it doesn't seem like it is doing. If it doesn't put the variables somewhere for you, you can't use them. To see if they are getting sent to your file, somehow, print all the possible variables.

print_r($_POST);
print_r($_GET);
print_r($_SESSION);

Look through those outputs and see if there is anything you can use.

Hello everyone,

Thank you guys for your reply, i was able to figure out the original problem, with some help of course.

Now i have another issue...anyone know how to submit data to a database and an e-commerce gate at the same time. Say for example, after the user selects a product, enters all of the necessary information, a page is echo to them, giving them a chance to review the information they have submitted. When they push the submit button, I would like the data entered be sent to the data base and the next screen be the credit card gateway screen.

I can do this independently, but at moment not simultaneously!

any help would be appreciated....

Thanks in advance...
