It is quite easy to develop a Drupal custom module in any Drupal custom application development by following certain standard procedures. First, the Drupal developers write the required information and a small description into the modulename.info file, such as Module Name, Version Information and Dependencies, Package Name, Description, Name, and Package. The above information and description must be related to the project so that the Drupal custom module is easily identified. The second step is the creation of a modulename.install file. The developers normally use hook_install() for the creation of tables or storage of values in the database. Then, a folder is created in the modules directory, such as ‘MyProject_Modules’, containing all the custom modules in ‘MyProject’. This is followed by writing the appropriate comment before each function or hook. All the codes are written only in function or hook only. Instead of fetching information through queries, it is ideal to get functions available in Drupal.api and use the api form to create HTML forms.
Three Types of Drupal Modules
Any Drupal website would normally have three types of Drupal modules. The first type of modules is the core modules that are shipped with Drupal. These core modules had been approved by the entire Drupal developer community. The second type of modules is contributed modules, which had been written or developed by the international Drupal developer community. These contributed modules are shared under GNU Public License, similar to Drupal itself. The third type of modules is custom modules that are created by the particular website designers and developers. It is possible to create Drupal modules in various Drupal versions, such as Drupal 5.x modules, Drupal 6.x modules, and Drupal 7.x modules. Further, these modules could be integrated with other third party applications for even better web designs and content creation. The multilingual support of Drupal is helpful in internationalizing the website design and development. Since Drupal module development is constantly evolving, it is possible to update the Drupal modules on a regular basis to improve the website continuously.
Development and Application of Drupal Plugins
The Drupal plugin manager is easy to download and install. When the plugin manager module is installed, it makes the downloading and installation of all other Drupal modules directly into the server a simple process. The process of Drupal plugin development starts with the downloading the plugin file and unzipping it. The unzipped folder is uploaded to the ‘sites/all/modules’ directory, which is created, if it does not already exist. By logging into the Drupal account, the plugin preferences are set through the standard save configuration process. Several other Drupal plugin development applications are possible for different purposes like live chat. With live chat Drupal plugin, it is possible to increase sales, offer better online support, and reduce costs. This type of Drupal custom application development with Drupal modules and Drupal plugins is the main attraction of Drupal among developers.
