Make the confirmation page add the values into database and create a script which processes the values from the database, meaning:
when user enters the page, your code will do something like this:
INSERT INTO sms SET to='$to', text='$text', sent=0;
and then you make a script which does the following:
ini_set("soap.wsdl_cache_enabled", "0");
$parameters['username'] = "xxxxxxxxxxx";
$parameters['password'] = "xxxx";
$parameters['from'] = "1000947320";
$parameters['isflash'] =false;
$sms_client = new SoapClient('http://87.107.121.54:2620/post/send.asmx', array('encoding'=>'UTF-8'));
$query = mysql_query("SELECT * FROM sms WHERE sent=0");
while( $message = mysql_fetch_assoc($query) ) {
$thisMessage = $parameters;
$thisMessage['to'] = $message['to'];
$thisMessage['text'] = $message['text'];
$sms_client->SendSimpleSMS2($thisMessage)->SendSimpleSMS2Result;
mysql_query('UPDATE sms SET sent=1 WHERE id='.$message['id']);
}
and you run this script in cron, lets say every minute or how often do you want to.
