    Hi there,

    I have some code which works pretty fine with the variables filled in from a SMS gateway provider:

    
 <?php
//set up variables
$info = "1";
$test = "0";
$address = "www.xxx.com/sendsms.php";
$message = "Hello this is a test";
$message = urlencode($message);
$from = " ";
$uname = " ";
$pword = " ";
$selectednums = " ";

//build url
$data = "uname=" . $uname . "&pword=" . $pword . "&message=" . $message . "&from=" . $from . "&selectednums=" . $selectednums . "&info=" . $info . "&test=" . $test;

//send messages
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://$address");
//curl_setopt($ch, CURLOPT_URL,"https://$address"); 
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
 output
$result = curl_exec ($ch);
curl_close ($ch);
?>
    PHP:
    I go to the page and the script sends the SMS - cool.

    How do I go about adding a form for the message and a submit button so that users can put in a custom message and the script does not execute straight away?

    I have tried adding something like:

    
<form action="<? echo $PHP_SELF; ?>" method="post">
	  	
          <label for="message" class="sb1">Message:</label><br /><br />
          <textarea name="message" id="txtarea"><? echo $message; ?></textarea><br /><br />
         
	  <input type ="hidden" name="tried" value="yes" />
          <input type="submit" id="btnsubmit" name="Submit" value="<? echo $tried ? 'continue' : 'send'; ?>">
     </form>
    HTML:

    But its not working yet. I think this is an easy one, but not to a PHP noob like myself :p

    When the user submits the form you now need to get the data from the form into your $message variable. This should do it:

    $message = $_REQUEST['message'];

    You'll likely need to do some validation of the message - like ensure it's not too long and all that - before you use it.

    many thanks jnestor.

    I opted to use: $message = $_POST['message'];

    and it looks like its running fine, although I have got an error message from the script / provider when the page loads:

    Error=Message not sent. Please check your data - especially the numbers. Are they all in INTERNATIONAL format?
    Message:

    Any ideas how to get rid of this - it would be okay if it was just me using this as I could ignore it but I am thinking of my users..

    The message box and submit now works though...

    Also how to validate - I guess as this is a SMS service I am limited to 160 characters - any clues as to how I should go about this?

    Thanks again
