Always give the full error including the line number. And make sure to tell us which line that number refers to. Right now you've given us an error and a whack of code, with no way to identify where in that code the error is coming from.

This:

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

Should most likely be this:

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

xmuzukerx · March 25, 2013

This:
foreach ($tel as $_POST['CTL_TEL']) {
Should most likely be this:
foreach ($_POST['CTL_TEL'] as $tel) {

already changed, but still got an error

haku · March 25, 2013

Should we start making random guesses as to what that error may be?

Should we start making random guesses as to what that error may be?

i've known the error but cant find a way to create a foreach loop whereby it will send a sms towards every recipient entered in the form, here's the part where looping is done

<?php
 
 
error_reporting(E_ALL ^ E_NOTICE);

$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->debug = false;
$gsm_send_sms->port = 'COM6';

And you want us to guess what this error is? What do I get if I am able to guess correctly?

xmuzukerx · March 25, 2013

Sorry...i'm just asking for help, to create a successful foreach loop that can sent to many recipient...thats all i need

haku · March 25, 2013

And how do you expect us to help you when you don't tell us what the error you are seeing is?

DaveyK · March 25, 2013

Just tell us what the error is

xmuzukerx · March 25, 2013

I'll try to explain as detail as i can

The error is at the foreach (line 68). whereby it says Warning: Invalid argument supplied for foreach() in C:\xampp\...on line 68

Reason:

I want to use the foreach loop in order to send sms to more than one recipient, and when i try, this form can only send sms towards one recipient only, if i add 4 recipient number, it only send sms to the last recipient, the remaining 3 recipient did not get the sms, can someone help me on how to make it send to every recipient

Firstly, the name of the input elements should be "CTL_TEL[]" NOT "CTL_TEL", this will send an array of value to the processing script.

On the processing script, this:

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

Should be:

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

Then that would mean, you only need the following $status variable instead of both:

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

Another thing, use some validation, to ensure data coming in to the processing script is exactly what you are expecting.

thank you, it worked and does sent sms to each recipient, but may i know what kind of validation that ensure data coming? for example?

You can imagine that, if someone were to send a string instead of a number, you would still attempt to send a text to that string, and that would be a bad sitaution, right?
