Please note that many of these fields are available as parameter types in Joomla! For a list of parameter types, see J1.

The use of File as the cache storage mechanism means that Joomla will write files in the folder defined by the Global Configuration parameter System tab "Path to Cache Folder".

Within each folder are the cached files which you can edit and view the cached serialized data. Most of the methods have already been described, but here is a summary of the key methods which you may wish to call from your code. This function returns to you the instance of the cache CallbackController class.

Once you have a handle on the cache CallbackController instance you can call something like:. Within the code for the get method Joomla does raise exceptions, but these relate to the case where you have tried to use a cache mechanism that is not supported.

However, you will usually not need to call this function directly, because if you use the cache get method then this will store it for you automatically. Below is the code for a simple Joomla module that you can install and run to demonstrate the use of the Joomla cache functionality.

If you are unsure about development and installing a Joomla module then following the tutorial at Creating a simple module will help. Within your Joomla administrator go to Install Extensions and via the Upload Package File tab select this zip file to install this sample cache module.

The module also displays the current time. If when you reload the page the current time doesn't change, then it means that the whole module output is being cached, and not being run on page reload. This will happen if:. It's instructive to experiment with the various cache settings, view the cache files in the file system and use the administrator Clear Cache functionality to clear the cache for this specific module.

It is my understanding, that the custom field is not recognised. Since the textfield is displayed, but not the desired dropdown with 3 options as seen from the UserFieldList class. So is there a way to implement a customfield inside the modules. Thank you in advance :. Also for a module Joomla will look in a subdirectory called field for custom field definitions, so if you put your UserFieldList.

Finally, setting the default value to array 2, 3 only works if you have the multiple attribute in your field xml. But because you want to save the field in the database, when you redisplay it you just want the value set to whatever was in the database.

So really leave that out and Joomla will set the value based on the database setting. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
