Question

How do I post them to whatever page from here and how can I send these variables to several pages at the same time?

//catched those variables within the same page
$event = $_POST['event'];
$when = $_POST['eventdate'];
$where = $_POST['place'];
$name = $_POST['name'];
$tel = $_POST['tel'];
$email = $_POST['email'];
send $event, $when, $where, ... to("whateverurl1");//not the way

Answer 1

POSTing data to an URL can be done with the curl extension, which allows one to send HTTP requests from PHP.

In your case, something like this might do the trick :

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'event' => $event, 
    'when' => $when, 
    // ... more here
));
$returned = curl_exec($ch);
curl_close($ch);

For more informations you might want to take a look at the manual page of curl_exec, and for more options (there are a lot of possible options !), see curl_setopt.

Here, the most important ones are :

• CURLOPT_URL : to specify the URL to which you want to post your data
• CURLOPT_POST : as you want to send an HTTP POST request — and not GET, which is the default
• CURLOPT_POSTFIELDS : to specify the data that you want to send

But note this will not send several queries in parallel — maybe curl_multi_exec and the other curl_multi_* functions could help, there…
