Thanks.
I read a bit more about it.
I use a class made by Micah Carrick, I found it on phpclasses.org
And I'm using authors example script. The problem is that I don't receive a notification from paypal. I'm testing it with my sandbox account...
This is the test file:
PHP Code:
<?php
require_once('paypal.class.php'); // include the class file
$p = new paypal_class; // initiate an instance of the class
$p->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; // testing paypal url
$this_script = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
// if there is not action variable, set the default action of 'process'
if (empty($_GET['action'])) $_GET['action'] = 'process';
switch ($_GET['action']) {
case 'process': // Process and order...
$p->add_field('business', 'anton._1209229536_biz@gmail.com');
$p->add_field('return', $this_script.'?action=success');
$p->add_field('cancel_return', $this_script.'?action=cancel');
$p->add_field('notify_url', $this_script.'?action=ipn');
$p->add_field('item_name', 'Paypal Test Transaction');
$p->add_field('amount', '1.99');
$p->submit_paypal_post(); // submit the fields to paypal
break;
case 'success': // Order was successful...
echo "<html><head><title>Success</title></head><body><h3>Thank you for your order.</h3>";
foreach ($_POST as $key => $value) { echo "$key: $value<br>"; }
echo "</body></html>";
break;
case 'ipn': // Paypal is calling page for IPN validation...
if ($p->validate_ipn()) {
$fp = fopen("pp.txt","a");
fwrite($fp, "test");
fclose($fp);
}
break;
}
And this is the class:
PHP Code:
<?php

$text .= "IPN POST Vars from Paypal:\n";
foreach ($this->ipn_data as $key=>$value) {
$text .= "$key=$value, ";
}

$text .= "\nIPN Response from Paypal Server:\n ".$this->ipn_response;
// Write to log
$fp=fopen($this->ipn_log_file,'a');
fwrite($fp, $text . "\n\n");
fclose($fp); // close file
}
function dump_fields() {
echo "<h3>paypal_class->dump_fields() Output:</h3>";
echo "<table width=\"95%\" border=\"1\" cellpadding=\"2\" cellspacing=\"0\">
<tr>
<td bgcolor=\"black\"><b><font color=\"white\">Field Name</font></b></td>
<td bgcolor=\"black\"><b><font color=\"white\">Value</font></b></td>
</tr>";
ksort($this->fields);
foreach ($this->fields as $key => $value) {
echo "<tr><td>$key</td><td>".urldecode($value)." </td></tr>";
}
echo "</table><br>";
}
}
I removed the coments so the files are shorter. |
