Hi guys, I need your help. When I entered the value number on the form one-line textbox and when I submits the button to redirect to the next page, there is no value displaying next to the amount when I entered the value on my form. Here it is the code: <?php $p = new paypal_class; $p->add_field('business', 'me@mail.com'); $p->add_field('first_name', $_POST['first_name']); $p->add_field('shipping', ''); $p->add_field('', 'http://www.domain.com/logo.jpg'); $p->add_field('return', 'http://www.domain.com/success.php'); $p->add_field('cancel_return', 'http://www.domain.com/cancelled.php'); $p->add_field('notify_url', '2'); $p->add_field('cmd', '_xclick'); $p->add_field('currency_code', 'USD'); $p->add_field('lc', 'US'); $p->add_field('bn', 'toolkit-php'); $p->add_field('no_shipping', ''); $p->add_field('no_note', '1'); $p->add_field('cn', 'Comments'); $p->add_field('cs', ''); $p->add_field('quantity', '1'); $p->add_field('item_name', 'Add fund to my account'); $p->add_field('amount', $_POST['script.php', formtext1']); $p->add_field('item_number', '777'); $p->add_field('undefined_quantity', ''); $p->add_field('on1', ''); $p->add_field('os1', ''); $p->add_field('shipping', ''); $p->add_field('shipping2', ''); $p->add_field('handling', ''); $p->add_field('tax', ''); $p->add_field('custom', ''); $p->add_field('invoice', ''); $p->add_field('first_name', 'test'); $p->add_field('last_name', ''); $p->add_field('address1', ''); $p->add_field('address2', ''); $p->add_field('city', $_POST['MyTown']); $p->add_field('state', ''); $p->add_field('zip', ''); $p->add_field('login_email', 'me@mail.com'); $p->add_field('night_phone_a', ''); $p->add_field('night_phone_b', ''); $p->add_field('night_phone_c', ''); $p->submit_paypal_post(); $p = new paypal_class; if ($p->validate_ipn()) { } class paypal_class { var $last_error; var $ipn_log; var $ipn_log_file; var $ipn_response; var $ipn_data = array(); var $fields = array(); function paypal_class() { $this->paypal_url = 'https://www.paypal.com/cgi-bin/webscr'; $this->last_error = ''; $this->ipn_log_file = 'ipn_log.txt'; $this->ipn_log = true; $this->ipn_response = ''; $this->add_field('rm', '2'); $this->add_field('cmd', '_xclick'); } function add_field($field, $value) { $this->fields["$field"] = $value; } function submit_paypal_post() { echo "<html>\n"; echo "<head><title>Processing Payment...</title></head>\n"; echo "<body onLoad=\"document.form.submit();\">\n"; echo "<h3>Please wait, your order is being processed...</h3>\n"; echo "<form method=\"post\" name=\"form\" action=\"".$this->paypal_url."\">\n"; foreach ($this->fields as $name => $value) { echo "<input type=\"hidden\" name=\"$name\" value=\"$value\">"; } echo "</form>\n"; echo "</body></html>\n"; } function validate_ipn() { $url_parsed=parse_url($this->paypal_url); $post_string = ''; foreach ($_POST as $field=>$value) { $this->ipn_data["$field"] = $value; $post_string .= $field.'='.urlencode($value).'&'; } $post_string.="cmd=_notify-validate"; // append ipn command // open the connection to paypal if(!$fp) { $this->last_error = "fsockopen error no. $errnum: $errstr"; $this->log_ipn_results(false); return false; } else { // Post the data back to paypal fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n"); fputs($fp, "Host: $url_parsed[host]\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ".strlen($post_string)."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $post_string .
