This is a multiple-article series of tutorials on how to develop a Model-View-Controller Component for Joomla! Version
.
Begin with the Introduction, and navigate the articles in this series by using the navigation button at the bottom or the box to the right (the Articles in this series).
This tutorial is part of the Developing an MVC Component for Joomla! 3.2 tutorial. You are encouraged to read the previous parts of the tutorial before reading this.
In this step we add a helloworld batch process to the backend. An accompanying video is available at Adding a batch process.
Introduction[edit]
Joomla provides a number of facilities to enable administrators to update articles and other types of item in batch. These include:
- moving or copying records into records with a selected category
- setting the language and/or access for the selected records
- adding a tag to the selected records
In this step we add these facilities into our helloworld component and also provide a batch process to enable the administrator to set the latitude and longitude.
Approach[edit]
To implement the batch processes we have to consider the following aspects.
Batch Button and Modal[edit]
- We show a Batch button in the toolbar on our helloworlds view. The administrator can click the checkboxes of the helloworld records to process in batch, and then click Batch to proceed.
- When the Batch button is clicked we want a modal to appear with the available options, so we must add the html for the Bootstrap modal. We'll do this in the helloworlds layout file, and utilise a couple of new subsidiary layouts for the modal body and footer.
The modal body will contain the html elements for the various options – eg set language, set access, set lat/long, etc. The elements for setting the language, access, category and tag are all standard Joomla library layouts within the /layouts directory tree. For setting the lat/long position we'll write our own layout file which we'll put in a new admin/layouts directory (and we have to remember to include this new folder in the main helloworld.xml manifest file).
The modal footer will contain the Cancel (for cancelling the operation) and Process (for starting the batch process) buttons.
Handling the HTTP POST in the Controller[edit]
When the Process button is pressed the javascript code will submit the form and so initiate an HTTP POST request to the server with parameters which include
- the ids of the records which have been selected for batch processing
- the batch options which have been chosen
- the task variable set to task=helloworld.batch
Joomla will route this to a batch() method in admin/controllers/helloworld.php.
In our helloworld controller batch() method we do the following:
- set up the model to be the helloworld model
- set up the redirect to present the helloworlds view again, once the batch processing is complete
- call the parent batch method, passing the model as parameter
The parent batch method (in JControllerForm) will obtain the POST params, perform some verification of them, and then call the batch() method within the passed model, passing the POST parameters.
Executing the batch processes in the Model[edit]
The way the Joomla batch model functionality works is that the JModelAdmin class has a property $batch_commands which is an associative array mapping the index of the batch parameters to the method which will perform that batch operation.
protected $batch_commands = array( 'assetgroup_id' => 'batchAccess', 'language_id' => 'batchLanguage', 'tag' => 'batchTag', );
So if in the batch modal an administrator sets the language selector to one of the available languages then batch[language_id] is set within the HTTP POST parameters. The model code looks up "language_id" in this $batch_commands property, finds "batchLanguage" and then proceeds to call the method batchLanguage().
In our case we will have a method called batchPosition() which will set the lat/long for the selected records, so we need to ensure that:
- the html input elements are defined so that batch[position] parameters are sent in the HTTP POST
- we add an extra record to the $batch_commands array, namely 'position' => 'batchPosition'.
The first aspect is done where we define the html of the input elements in our modal body.
The second aspect is done in a batch() method which we write in our helloworld model. This adds in the extra array element and then calls the parent::batch() to initiate all the batch operations.
Finally we must write our batchPosition() method to update the set of records with the passed-in latitude and longitude values.
Batch Button[edit]
We add the batch button in our helloworlds view. Because this is a custom button we need to get a handle on the toolbar instance, and then use appendButton(), as we can't use a ToolbarHelper function for this.

We put the html for the modal body into a new default_batch_body.php file, using standard Joomla layouts for the standard options. For our Position option we render a layout which we define ourself below.

The html for the modal Cancel and Process buttons we put into the batch footer file.

Controller Changes[edit]
In our helloworld controller we override the JControllerForm batch() method in order to set the model and the redirect back to the same URL, before continuing with the normal batch processing.

Model Changes[edit]
We override the JModelAdmin batch() method in order to include our own batch Position method in the array of batch processes. We then write our batchPosition() method, which will check that the user has permission to change each of the helloworld records, and then apply the lat/long changes to the records.
We also override the generateTitle() method which is used to generate a new title in the case where we're copying a record into a new category and there's a problem of uniqueness of the alias field (similar to the Save as Copy issue which was addressed in the Adding an alias tutorial step). We need to override the method because it assumes that 'title' is the name of the field to adjust, whereas in our case the field name is 'greeting'.
In addition, as described in the accompanying video, the JModelAdmin functionality for copying records into a different category doesn't quite work for components with Levels. To correct this we can override the JModelAdmin batchCopy() method and include code to position each new record before it is saved.
