I am trying to setup a paypal exprss checkout form using wordpress ( with custom coded theme) and
WordPress › Support » PayPal Express Checkout
plugin

the problem is that i am unable to show the item name on the paypal form.

here are the three files.

this is the main submit file
Code:
<input type="hidden" value="" name="url" id='url'>                        
                        <input type="hidden" value="" name="AMT" id='AMT'>                        
                        <input type="hidden" value="" name="CURRENCYCODE" id='CURRENCYCODE'>                        <input type="hidden" value="" name="func" id='func'>
                        <!--<input type="hidden" value="theme" name="item_name" id='theme'>
                        <input type="hidden" value="" name="desc" id='249theme'>
                        <input type="hidden" value="" name="item_name" id='item_name'>
                        <input type="hidden" value="" name="amount" id='amount'>
                        <input type="hidden" value="" name="shipping" id='shipping'>
                        <input type="hidden" value="" name="currency_code" id='currency_code'>
                        <input type="hidden" value="" name="lc" id='lc'>                              -->                        <input type="hidden" value="<?php echo $_GET['ttype'] ?>" name="ttype" id='ttype'>                        
                        <input type="hidden" value="<?php echo $_GET['price'] ?>" name="iprice" id='iprice'>
                        <input type="hidden" value="<?php $postid=$_GET['theme_id'];$title = get_post($postid)->post_title;echo $title; ?>" name="itheme" id='itheme'>
                        <input type="hidden" value="<?php echo get_option('wpeeedy_twitter'); ?>" name="twitter" id='twitter'>
                        <input type="hidden" value="<?php echo get_option('wpeeedy_facebook'); ?>" name="facebook" id='facebook'>
                        <input type="hidden" value="<?php echo get_option('wpeeedy_googleplus'); ?>" name="googleplus" id='googleplus'> 
                    </form>
it submits to email.php file

Code:
;$URL = get_value("url");$AMT = get_value("AMT");$CURRENCYCODE = get_value("CURRENCYCODE");$func = get_value("func");$headers = "MIME-Version: 1.0" . "\r\n";$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
mail($to, $subject, $message,$headers);
mail($touser, $subject2, $messageuser,$headers);
echo 'Waiting';
echo '<form method="post" id="sub" action="'.$URL.'">';
echo    '<input type="hidden" name="AMT" value="'.$AMT.'">';
echo    '<input type="hidden" name="CURRENCYCODE" value="'.$CURRENCYCODE.'">';
echo    '<input type="hidden" name="PAYMENTREQUEST_0_DESC" value="Website Setup | '.$ttype.' package">';
echo '<input type="hidden" name="item_name" value="2.2">';
//echo    '<input type="hidden" name="PAYMENTREQUEST_0_QTY0" value="1">';
//echo    '<input type="hidden" name="L_PAYMENTREQUEST_0_DESC0"  value="website">';
echo    '<input type="hidden" name="func" value="'.$func.'">';
echo '</form>';
echo "<script>document.getElementById('sub').submit()</script>";

it submits to the plugin form, which has paypalapi.php

Code:
<?php
session_start();

/**

if ( ! class_exists('HCCoder_PayPalAPI') ) {

  class HCCoder_PayPalAPI {

  • Neither of the PHP files REALLY refer to the item_name. Of course, the email php file sets the item_name to 2.2.
