Installing SMS::Send::IN::eSMS send driver for Koha ILS

An easy peasy HOWTO along with a few under-the-hood details explained.

Step #1 : Installing the SMS::Send::IN::eSMS module from CPAN

Login as a sudo user and start the CPAN shell using the command sudo perl -MCPAN -e shell. Install the driver by typing in install SMS::Send::IN::eSMS. If everything works OK, you should see output on screen similar to this:

With the SMS::Send::IN::eSMS module installed, we’ll now set up the Koha side of things.

Step #2 : Making a one-line change to Koha’s

Assumption : That you are using a .deb package based installation. If you are using a git or a tarball installation you probably do not need this guide. πŸ™‚

The code in file /usr/share/koha/lib/C4/ is what Koha uses to communicate with the SMS provider (in this case eSMS Kerala from KSITM) via the send driver. This code is capable of accepting two parameters i.e. (a) username and (b) password of the user with the SMS service provider via whom the user wants to send out the messages. However due to Telecom Regulatory Authority of India (TRAI) rules, in India we need to use three parameters, the third one being a mandatory, 6-character, nationally unique senderid allotted to every bulk transactional SMS sender in India. As of version 16.11 Koha can not handle this AS-IS.

Therefore, to make SMS work with Koha in India, we need to make a one-line change to the code. Look for the following code around line no. 80 of the file /usr/share/koha/lib/C4/

# Create a sender
$sender = SMS::Send->new( $driver,
                          _login    => C4::Context->preference('SMSSendUsername'),
                          _password => C4::Context->preference('SMSSendPassword'),

Add the following line : _senderid => C4::Context->preference('SMSSendSenderID'),, so that the code looks like this:

# Create a sender
$sender = SMS::Send->new( $driver,
                          _login    => C4::Context->preference('SMSSendUsername'),
                          _password => C4::Context->preference('SMSSendPassword'),
                          _senderid => C4::Context->preference('SMSSendSenderID'),

Save and close the file. Now login into the staff client and add the four necessary system preferences – (a) SMSSendDriver, (b) SMSSendUsername, (c) SMSSendPassword and (d) SMSSendSenderID. Now, if you are on Koha 3.22 or higher version (i.e. 16.05 or 16.11), you will find the first three under Patron preferences and you only need to create the last one i.e. SMSSendSenderID to complete the setup.



However, if you are still using Koha 3.18.x or 3.20.x series then you will need to create three Local use preferences i.e. SMSSendUsername, SMSSendPassword and SMSSendSenderID. Either way, set these four parameters to your actual settings and you are ready to go start using the installed driver.

N.B.This behaviour will change from Koha 17.05 onward (estimated release date May 2017) when the bug number 13029 – “Allow to pass additional parameters to SMS::Send drivers” becomes generally available as part of the stable releases.

Troubleshooting #1 – Missing ‘make’

‘Make’ is required to configure and install the driver. So, if you see an error that reads as

Running make for I/IN/INDRADG/SMS-Send-IN-eSMS-0.01.tar.gz
Can't exec "/usr/bin/make": No such file or directory at /usr/local/share/perl/5                                                                                                             .20.2/CPAN/ line 2197.
  /usr/bin/make -- NOT OK
  No such file or directory
Failed during this command:
 INDRADG/SMS-Send-IN-eSMS-0.01.tar.gz         : make NO

Exit from cpan by using the command exit and from the command line install make by entering the command sudo apt-get install make. Once make is installed, run sudo perl -MCPAN -e shell and then proceed with driver installation using the command install SMS::Send::IN::eSMS.

Troubleshooting #2 – CPAN index is out of date

After typing in the command ‘install SMS::Send::IN::eSMS‘ if you find yourself facing the error Warning: Cannot install SMS::Send::IN::eSMS, don’t know what it is., DO NOT panic! It happened to us on one of our test servers too πŸ™‚

It simply means your CPAN index metadata is out-of-date, and you need to refresh the index by running the command ‘reload index‘. After the updated index is fetched, re-run the command install SMS::Send::IN::eSMS. It will work this time.

Good news for Koha users in Kerala : SMS Send driver for eSMS Kerala service released as Free Software (FOSS)

ANNOUNCEMENT: L2C2 Technologies has released the SMS::Send::IN::eSMS driver required by Koha ILS users using the eSMS Kerala service provided by the Kerala State IT Mission under a Free Software license. The development of the driver was made possible by the funding support of the State Librarian, State Central Library, Thiruvananthapurm (Trivandrum), Kerala, with KELTRON (Kerala State Electronics Development Corporation Ltd) acting as the facilitator. Any Koha library in the state of Kerala who are eligible to use the eSMS Kerala SMS service (provided by KSITM) can now freely implement SMS support using this driver.

With this release, it becomes the second open source regional SMS::Send driver now available to Indian Koha users that can be freely downloaded from the Comprehensive Perl Archive Network or CPAN.

Sending SMSes from Koha

For a long time now Koha has supported sending of SMS (short message service) text messages to library patrons and users about account creation, issue, return, fines, holds, overdues, purchase suggestions etc. To send out SMSes from Koha, we have to use the SMS service of a bulk transactional SMS service provider who provides that service.

What are SMS::Send drivers and why does Koha need them?

In order to communicate with the service provider’s messaging sending interface (also called messaging API), Koha uses a type of software called “SMS::Send driver”. The “catch” being that each service provider requires a different SMS Send driver. Sort of like the SIM card in our cellphones e.g. if we wish to use a Vodafone number we must have a Vodafone SIM card. However, unlike a SIM card the SMS::Send driver which is a software module written in the PERL language is not provided by the SMS service provider. Either one has to use a Free & Open Source send driver that already exists OR one has to write one by referring to (usually) the HTTP API of the SMS provider.

About eSMS Kerala

eSMS is an exclusive SMS Gateway established by the Kerala State IT Mission for use by various government departments for providing departmental services over mobile phones.

Downloading the driver

The SMS::Send::IN:eSMS driver can directly downloaded from CPAN by visiting or from L2C2 Technologies’s public repository on Github at

Adding autocomplete support to MARC21 260 / 264 (imprint) fields in Koha

Adding auto-complete feature to Koha’s MARC21 260 / 264 field (Imprint – place, name of publisher, distributor etc) as a cataloging aid.

As per LC’s AACR2 (as well as RDA) instructions, the imprint information as captured in MARC21 field 260 (AACR2) and 264 (RDA) should be *transcribed* and not *recorded* using the principle – “Take What You See and Accept What You Get” [1]. As a result, the 260$a (place) and 260$b (publisher, distributor etc) are usually not handled as fields whose values are controlled using authorized values.

Up until 2001, the 260 field was a NR field. It was made repeatable to accomodate frequent publisher name changes.

Since the 260$a and 260$b are not usually guided by authorized values, it is noted (at least in the Indian sub continent context) that catalogers often make typographical errors while transcribing the data, e.g. “Pearson Education” may be inadvertantly added as “Peerson Education” or as even as “Pearshon education”, while “Kolkata” may have been entered both as “Kolkata” as well as “Kolkatta” or even as “Kolkhata”. Without authority control of the field, this cataloging quality check is often overlooked. Errors like this often end up affecting the result of advanced searches or custom SQL reports.

Luckily for us, Koha ILS uses jquery extensively while (via jquery-ui) provides for nice autocomplete widgets, like the ones we see in action when we type in part of the borrower’s name in patron search (checkout) or in the authoritiy headings search, where entering 3 characters triggers the AJAX based lookup with the option to select one of the offered list *OR* to type in our own.

AJAX stands for “Asynchronous Javascript and XML”. In simple terms it encompasses a set of web development technique that allows us to fetch and load data from a remote server into our currently open page, without requiring us to refresh / reload the page. [2]

Recently a client requested that we offer them a way to look up publisher names and place names (for field 260) already entered into their Koha instance, without having to type it all in every time. For example in their database they already had the following publisher names entered – “Pearson Education, Prentice Hall India, PacktPub, Press Trust of India” etc. Now they if they encountered an item that was from these publishers they should be able to pull up a list just by entering “P” into the 260$b field and then be able to select the one applicable. And if they encountered a publisher name say “Penguin Books”, they should be able to type it in as well.

Koha 16.11 ships with 3 (three) different scripts that show us how to achieve this. You can find out which ones these are by using the command `locate`. NOTE: You may be required to run `sudo updatedb` once before locate finds the files. For our requirement we modeled our script which we’ll call on /usr/share/koha/intranet/cgi-bin/cataloguing/ You can grab a copy of from L2C2’s github repo here [3]. The script returns a JSON based result set if results matching your input is found.

Remember that **every** script that Koha executes, needs it executable bit set, and so does this one. Therefore, do *not* forget to set the executable bit for the script with `sudo chmod a+x /usr/share/koha/intranet/cgi-bin/cataloguing/` before you proceed to the next step.

Step #2 : Enabling the fields

With the script in place, we now need to turn to IntranetUserJS system preference and enter the following jquery snippet to enable autocomplete in 260$a and 260$b :

  $( '[id^="tag_260_subfield_a"]' ).autocomplete({
    source: function(request, response) {
        url: "/cgi-bin/koha/cataloguing/",
        dataType: "json",
        data: {
          term: request.term,
          table: "biblioitems",
          field: "place"
        success: function(data) {
          response( $.map( data, function( item ) {
            return {
              label: item.fieldvalue,
              value: item.fieldvalue
    minLength: 1,
  $( '[id^="tag_260_subfield_b"]' ).autocomplete({
    source: function(request, response) {
        url: "/cgi-bin/koha/cataloguing/",
        dataType: "json",
        data: {
          term: request.term,
          table: "biblioitems",
          field: "publishercode"
        success: function(data) {
          response( $.map( data, function( item ) {
            return {
              label: item.fieldvalue,
              value: item.fieldvalue
    minLength: 1,

A video of autocomplete in action


By tweaking the script or even by completely re-writing it to use the various search functions shipped by Koha inside its /usr/share/koha/lib directory on a .deb package based installation, you can do so much more than possible with this simple hack. Happy hacking! πŸ™‚ [4]






JQuery tips for Koha : Adding easy to use indicator picklists

Adding picklists for selecting indicators for MARC tags used in Koha’s cataloging worksheets.

During data audits of users’ MARC21 data, quite frequently we find that most, if not all, records are often without any form of use of indicators. Trained library professionals often give a sheepish grin when asked why they didn’t add them while cataloging the documents. πŸ˜‰ But trained librarians are not the only ones who work with Library systems like Koha. There are many people who find themselves working in a library without a formal training or sufficient theoretical background on MARC21. Generally speaking reasons for not adding the indicators range from:

  • Lack of practise – thus unsure of the correct indicator to use.
  • Lack of awareness – i.e. untrained people with a very basic knowledge of cataloging
  • Lack of user-friendly mechanism to input indicators
  • And lastly – sheer laziness

Now, about the last one we can’t do anything about, however the rest of the reasons might use a bit of leg-up! So here goes the newest tutorial on how to add easy-to-use picklists to help us correctly populate the indicators.

According to the Design Principles of MARC21, indicators form a part of the family of content designators [1]. As defined, an indicator is :

A data element associated with a data field that supplies additional information about the field. An indicator may be any ASCII lowercase alphabetic, numeric, or blank.

For this tutorial we will focus on MARC21 bibliographic data fields 100 and 110 i.e. Main Entry Personal Name and Main Entry Corporate Name respectively. We will not touch the Koha template files at all, rather as per the global best practice for Koha ILS, we will utilize only JQuery (JavaScript) and HTML via the Koha system preference IntranetUserJS.

Step #1 – Finding out the DOM nodes

We will start by going to Home > Cataloging > Add MARC record in Koha and select the framework we want to work on. In this case we chose to work with the “Default framework” that is shipped with Koha. We used Google Chrome’s Developer Tools Inspect option [2] to find out what is the id of the selector (DOM node) we need for Main Entry Personal Name.

Since we need space to setup the picklist we chose to use the free space available on the div that displays information about the field that follows immediate after it. As you can see in the image below that div has an id identifying it, which is very good for us, since it makes selecting the DOM node absolutely painless.


It should noted that when Koha renders the cataloging interface, it suffixes the HTML element IDs with a random number (one for each new tag). In this case, the id was div_indicator_tag_100_838390 where “838390” is the random suffix number. We needed to latch on to the first part i.e. div_indicator_tag_100.

Step #2 – Let the JQuery magic work

We have to add the select dropdown picklists right after the text on the div_indicator_tag_XXX DIVs. The value we will use for the indicators will come from here and here respectively.

if ( $("#cat_addbiblio") ) {	// only while adding biblios
  $('div[id^="div_indicator_tag_100"]').append(' <label for="tag_100_indicators">Apply Ind1, Ind2</label> <select id="tag_100_indicators"><option>-Select-</option><option value="1">1 - Surname</option><option value="0">0 - Forename</option><option value="3">3 - Family name</option></select>');
  $('div[id^="div_indicator_tag_110"]').append(' <label for="tag_110_indicators">Apply Ind1, Ind2</label> <select id="tag_110_indicators"><option>-Select-</option><option value="2">2 - Name in direct order</option><option value="0">0 - Inverted name</option><option value="1">1 - Jurisdiction name</option></select>'); };   // end if


While that added the picklists, we still have to add the actual logic that will allow the indicators to be populated on selecting from the list. Again we will turn to JQuery for the following snippet:

    var what_clicked_100 = $('#tag_100_indicators').val();
    if ( !isNaN(what_clicked_100) ) {
    } else {
    var what_clicked_110 = $('#tag_110_indicators').val();
    if ( !isNaN(what_clicked_110) ) {
    } else {

The code above is listening to see when we click and select a value from the picklists i.e. when we trigger a click JavaScript event. Next it checks if we had selected a real value OR whether we had just “clicked” on the placeholder “-Select-” option that no value. And lastly based on what we had selected it sets the ind1 and ind2 values according.



In this manner we can add easy-to-use picklists for indicators. Since it is now only a matter of selecting from the available values, it also reduces significantly the scope for typographical errors during data entry into the indicator boxes. Before we leave for today, do note that the second code listing may be better handled as a JavaScript function to which the references are passed to by a handler hook. Doing so would make for a cleaner and leaner implementation of this concept especially if you are planning to set it up for all the non control MARC21 fields you use. Also, you may wish to implement the selected dropdown value check using something other than IsNan [3].

Koha Quick tip: Removing the dot from salutation like “Ms.” after a bulk patron import

A quick-n-dirty way to remove the trailing dot from salutation field after a bulk patron import into Koha.

Earlier today the deputy librarian at our client partner Gouri Devi Institute of Medical Sciences and Hospital (GIMSH) called us wanting to figure out how to fix a small, but crucial problem. The employee list from GIMSH’s HR department was used to create the patron bulk import CSV [1] file. All 143 records got imported without a glitch and each individual records looked perfectly OK when viewing them. However, when she tried to edit these patron records, she noticed that the salutation (e.g. Mr, Mrs, Ms etc.) would not show up in the salutation drop-down during edit! πŸ™

missing salutation
Missing salutation even though salutation was entered into the database


About 141 out of the total 143 records had a period.” after the salutation and two didn’t. These two records which did not have the period at the end of salutation were displaying the stored value correctly in the drop-down, rather than showing as being blank. As it happens, Koha uses the BorrowersTitles system preference to store the options to display. The default options are Mr|Mrs|Miss|Ms. As you can see, none of these have a period at their end. So, while the salutation field value was stored in GIMSH’s borrowers table, it was not being displayed during the edit as the value didn’t match with the values stored in BorrowersTitles syspref.

The “Fix”

***WARNING*** The following step requires you to directly execute a SQL on the Koha database. This is usually not recommended, but some times, it is required to quickly fix a problem.

Using the TRIM() string function of MySQL in tandem with the specifier trailing [2] we can take out the “.(period) at the end of the salutation from all the records in the borrowers table in the following manner:

UPDATE `borrowers` SET `title` = TRIM(TRAILING '.' FROM `title`);
salutation drop down is working now

Changing languages in the drop-down for Google Transliterate API

Choose the list of languages to transliterate on the Koha OPAC

This tends to be frequent question that we often end up fielding from colleagues and customers. But before we get into this, please remember that this feature is probably at the end of it shelf-life. There are two reasons for this – the Transliterate API that this feature depends on was deprecated many, many years back, and secondly how badly this API was put together – it fetches the necessary JavaScript library from Google’s servers over HTTP! So, if you are using HTTPS on your Koha OPAC, you can kiss this feature good bye right now! Being deprecated there is almost zero chance that Big G will do anything to change that.

Life sucks right?? πŸ˜‰ But as long as it is still there, here’s “one for the road”! πŸ˜€ So, read on!

Turning on Google Transliteration


It all starts with setting GoogleIndicTransliteration system preference to “Show” from the default of “Don’t show”.

By default that provides us with this short language drop-down:

For users from India, a country with 22 official language at the last count, that default list is woefully too little, too less. The good news is that Google’s Transliteration API supports several dozens of languages. Which ones? Well you need to dig around LanguageCode and SupportedDestinationLanguages enumerations in the documentation.

Show me the money!

The code to support the function is loaded via googleindictransliteration.js file that resides under /usr/share/koha/opac/htdocs/opac-tmpl/bootstrap/js/ on a Debian package based installation.

The screen grab below shows exactly that changes we needed to make in order to show on Hindi and Bengali as the list of languages, *and* with Bengali as default language option on the select drop-down.


So how did I know that I needed to use “bn” for Bengali? Well, that LanguageCode enum list I’ve linked to above. Simple really!

One more fact about this tip that will bug a few

Change(s) to the LanguagesCode enum like this within the googleindictransliteration.js file would cause *all* instances on a multi-tenanted Koha installation to display the same list of languages. So, if you need different sets of languages lists in different OPACs, you are probably out of luck.
