Start by setting up your form to call your PHP page:

Code:

<form name="myform" action="<path to PHP page>" method="post">

I don't know what you expect this to do:

PHP Code:


[PHPNET=""]<?php

but I'm pretty sure it is not what you want, or at least it will not do what you expect.

**ManiacDan**

PHPNET is a tag here on devshed, not part of his code. he double-highlighted it.

That being said...are you sure this is even possible?

I haven't used gsm_send but I've sent pages and messages via modem from a PHP server, if that is what you mean. Although now there are web services APIs that can do it without a modem.

**gw1500se**

Make your input list an array.

Code:

name="CTL_TEL[]"

You can then loop through that array in your script.

PHP Code:


foreach ($tel as $_POST['CTL_TEL']) {

.

.

.

}

.

}

This is the code that initialize sending sms is

Code:

$status = $gsm_send_sms->send($_POST["CTL_TEL"] , $_POST["CTL_MSG"]);
  
if ($status) {
	echo "Message sent\n";
} else {
	echo "Message not sent\n";
}


$gsm_send_sms->close();

So where exactly do i need to put the loop? so that it detects recipient's number form and sent it?

**gw1500se**

Put it around everything except the close. However, instead of using $_POST["CTL_TEL"] use $tel. You might also add that to your status messages so you know which succeeded and which failed.

is this correct?

Code:

foreach ($tel as $_POST['CTL_TEL']) {

$status = $gsm_send_sms->send($_POST["CTL_TEL"] , $_POST["CTL_MSG"]);


    

if ($status) {
	echo "Message sent\n";
} else {
	echo "Message not sent\n";
}
}

Not quite:

PHP Code:


$status = $gsm_send_sms->send($tel , $_POST["CTL_MSG"]);

P.S. Note the use of PHP tags.

Invalid argument supplied for foreach()

truly sorry, i'm really newbie here didnt get much on how to use the loop

Something is wrong with $_POST['CTL_TEL']. Do a var_dump($_POST) before the loop to see if CTL_TEL is really an array and contains the correct information. If not you need to fix your form so that it is.
