Retrieving Two-Way SMS Messages From Clickatell Gateway - Part 2

The first part of the tutorial on to retrieve two-way text messages from clickatell gateway was basically about creating a mysql database that will store data received from Clickatell Gateway via the Callback Url.

This tutorial is will just show you how to create your “settings.php” which declares the main settings of your programme. It stores your mysql login details and the clickatell gateway api login details.

All you have to do is copy and paste the code below and save it as “settings.php”. Then you change all the xxxx in the code to the appropriate values per your mysql database and your credentials at clickatell.

settings.php

<?php

$baseurl =”http://api.clickatell.com”;

//User details @ Clickatell
$user = “xxxx”;
$password = “xxxx”;
$api_id = “xxxxx”;

//mysql details
$hostname_conn = “xxxx”;
$database_conn = “xxxx”;
$username_conn = “xxxx”;
$password_conn = “xxxx”;
$conn = mysql_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error(mysql_error(),E_USER_ERROR);

?>

User Details @ Clickatell
//$user = This is the username assigned to you by clickatell
//$password = This your clickatell api password;
//$api_id = The api id can be generated on your clickatell control panel

User Details @ Clickatell
// $hostname_conn = This is your database hostname
//database_conn = Change this to the name of your database
// $username_conn = This is the user logon to ur database
// $password_conn = Change this to your database password

From Text Messaging to Data Protection

I have successfully completed my tutorials on how to Send SMS Message Using Clickatell API with a php script. The responses I have gotten so far are quite ok, so that means I am going to be moving to other topics in the subsequent weeks.

A friend of mine wants me to give more information about data maintenance and security in my subsequent articles and so in the next couple of weeks I will be doing more work on data handling.

Some of the vital topics I am going to be writing about are Continuous Data Protection, File Synchronization and Remote Access.

It will also include general tips on Data Protection, from backing up data to restoring data in all forms. Interesting features will also be given on the various kinds of Data and File Synchronization.

Whilst waiting for me to write on the above mentioned articles, you can check on Tilana Systems for the range of products they offer.

By the way have u heard of the current RSS battle between some top weblog monguls? More coming later

Send SMS Message Using Clickatell API - Part 7

After going through the first 6 parts of this tutorial, I realized I could do more to check the status of an sms message so i decided to add this part of the tutorial.

What this does is to check the status and charge of a message by your self just in case the callback url doesn’t give you the required feedback on time. Meaning this tutorial will help you to manual query the clickatell gateway to check the status of your sms message.

All you have to do is to create a page “status.php” and use the code below.

status.php

<?php

echo “loading……”;

require_once(’settings.php’);

// auth call
$url = “http://api.clickatell.com/http/auth?user=$user”;
$url = $url.”&password=$password&api_id=$api_id”;
$ret = file($url);

// split our response. return string is on first line of the data returned
$sess = split(”:”,$ret[0]);
$sess_id = trim($sess[1]);

mysql_select_db($database_conn, $conn);
$result1 = mysql_query(”select * from tbl_outbox where status <> ‘004′ and dayofyear(now()) - dayofyear(dated) < 1 limit 10″,$conn);
$result2 = mysql_num_rows($result1);

while ($mydata1 = mysql_fetch_array($result1)){
$messageid = $mydata1[’messageid’];
$api = trim($mydata1[’apimsgid’]);

//////////////////////////////////////////////
/////////////////////////////////////////////
// check charge
$charge_url = “$baseurl/http/getmsgcharge?session_id=$sess_id”;
$charge_url = $charge_url.”&apimsgid=$api”;
$charge_return = file($charge_url);

foreach($charge_return as $item){

$findapi = strpos($item, “apiMsgId:”);
$findcharge = strpos($item, “charge:”);
$findstatus = strpos($item, “status:”);

$length = strlen($item);

//Find the apimsgid
$part1 = substr($item, $findapi,$findstatus );
$part2no = strpos($item, $part1);

$api = trim(substr($item, $findapi,$findcharge ));
$status= trim(substr($item, $findstatus,$length ));
$charge= trim(substr($item, $findcharge, $findstatus - $findcharge ));

//find charge
$ret = $charge;
$sess = split(”:”,$ret);
$charge = trim($sess[1]);

//find status
$ret = $status;
$sess = split(”:”,$ret);
$status = trim($sess[1]);

mysql_select_db($database_conn, $conn);
$sql = “update tbl_outbox set status = ‘$status’ , charge = ‘$charge’ where messageid =$messageid”;
$result = mysql_query($sql, $conn) or die(mysql_error());
}
}
mysql_free_result($result1);

Send SMS Message Using Clickatell API - Part 6

The last part of the tutorial is using the callback url feature of the clickatell api. This feature allows the Clickatell gateway to forward message status details of the sms message you sent back to your server, through the url you provided on your control panel. This is quite tricky but its simple.

All you have to do is to log on to clickatell’s control panel, and choose the api_id you want to set your callback url.
The insert the url, eg. www.mboateng.com/callback.php.

Create a file “callback.php” on your server and paste the code below.

What will happen is that, any time you send an SMS Message to Clickatell’s gateway, it will forward the response in a url form to which ever url you will provide as your callback url.

callback.php

require_once(’settings.php’);

// Declare variables for url string
$url = $_SERVER[’QUERY_STRING’];

$api_id = $_GET[’api_id’];
$from = $_GET[’from’];
$to = $_GET[’to’];
$text = $_GET[’text’];
$dated = $_GET[’timestamp’];
$apiMsgId = trim($_GET[’apiMsgId’]);
$status = $_GET[’status’];
$charge = $_GET[’charge’];

mysql_select_db($database_conn, $conn);
$sql = “update tbl_outbox set url=’$url’, status = ‘$status’, charge = ‘$charge’ where apimsgid = ‘$apiMsgId’”;
$result = mysql_query($sql, $conn) or die(mysql_error());

mysql_free_result($rsOutbox);

Send SMS Message Using Clickatell API - Part 5

This part of the tutorial is probably the most important part of the whole tutorial in sending an sms message using the clickatell api. You will create a page “send.php”, then you copy and paste the php code in this page. The send.php does the following;

1. Authenticates with the Clickatell Gateway
2. Sends the SMS Message
3. Retrieve the apimsgid of the corresponding Text Message
4. Save the SMS Message and its Apimsgid into the Mysql Database

I have put comments at every step of the code so you can identify what is happening at every stage of the code.

Send SMS Message Using Clickatell API - Part 4

The next thing to do is create a file “settings.php” which will store general settings for sending sms messages using clickatell’s api.

settings.php

<?php

$baseurl =”http://api.clickatell.com”;

//User details @ Clickatell
$user = “xxxx”;
$password = “xxxx”;
$api_id = “xxxxx”;

//mysql details
$hostname_conn = “xxxx”;
$database_conn = “xxxx”;
$username_conn = “xxxx”;
$password_conn = “xxxx”;
$conn = mysql_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error(mysql_error(),E_USER_ERROR);

?>

User Details @ Clickatell
//$user = This is the username assigned to you by clickatell
//$password = This your clickatell api password;
//$api_id = The api id can be generated on your clickatell control panel

User Details @ Clickatell
// $hostname_conn = This is your database hostname
//database_conn = Change this to the name of your database
// $username_conn = This is the user logon to ur database

Send SMS Message Using Clickatell API - Part 3

The next part of the tutorial is the Interface to type your SMS Message. I have designed a simple interface that you can use. You can also design one yourself; and in designing one, just make sure you have the the following three fields

1. “to”
2. “from”
3. “Message”

“to”
This is the field where you type in the RECIPIENT NUMBER. Make sure it is in an international format. eg. +233244232323 or +16364545555

“from”
This is the field where you type in the either YOUR NUMBER or YOUR NAME. If you type your name, make sure you dont leave spaces.

“message”
This is the field where you type your MESSAGE. Clickatell sets the default message length to 160 characters, but you can increase it to any number you want on your Clickatell Control Panel.

Send SMS Message Using Clickatell API - Part 2

The second part of the tutorial is actually optional for those who know their way around php coding. These pages will help you diagnose errors with ease.

Create these three pages

1. failed.php
2. sent.php
3. badlogin.php

On sending the sms message three things are likely to happen;

1. Login Failure, i.e. failure to authenticate with the Clickatell Gateway
2. SMS Sending Failure , i.e. failure to send the sms
3. Successful message sending

And in any of the listed conditions above, you will be redirected to a corresponding php page to know where the fault it came from.

failed.php

Send SMS Message Using Clickatell API - Part 1

I have been receiving numerous emails on how to send SMS Messages using Clickatell’s HTTP API with a PHP script. I have therefore designed this tutorial to send a simple sms message using clickatell’s HTTP API.

This tutorial basically solves three things.

1. Send a simple sms message on clickatell’s sms gateway using HTTP
2. Retrieve the apimsgid of a message and stores it in a mysql table
3. Use the callback url to check the status of an sms message

Before you start, make sure the following have been done.

1. Register at Clickatell for your account.

2. Register for an HTTP API account at your clickatell control panel. Once you create and HTTP API account, you will be assigned the following. (username, password and api_id) wich you will insert in your script.

3. Whilst on the HTTP API control panel, assign the callback url. Eg. www.mysite.com/callback.php

Once all these are settle we will create our mysql table

Mysql
