Drupal module development has been recognized as the most effective way to increase Drupal’s functioning.


Drupal module development can be a tricky errand, if you don’t have much technical whereabouts. There are several techie hurdles that you might come face to face with.

This post briefly explores and untwines the story of variables in Drupal module development. So are you ready to get, set and delete variables in your Drupal website.

Personalizing with Variables- Understanding Them:

Variables are of utmost importance when you are using Drupal modules. Drupal stores it modules in the variable table. This means variables play a very essential role when you are looking to store some information and then retrieve it at a later instance. The information we store goes into the table, gets stored there and later on it can be easily restored from there, as and when required. There are, however, certain functions that are required in order to set functions, read them and delete them. Thus, alongside knowing the variables, you need to have a thorough understanding of these functions as well. Let us take a look at what these functions are all about.

Role Play by Variables- The Functions:

There are various functions that are employed in Drupal module development. Here are some of the most common and important ones:

1. variable_get($name,$default=NULL): As the name suggest, this variable is used to get the variable using name as a parameter and set its value as default in case there is no predefined value has been set. For instance, variable_get(new_var, 5), means finding new_var in the database and then setting its value as 5.

2. variable_set($name,$value): This function sets the variable by assigning it a particular name and value. For instance, variable_set(new_var, “hey”). Here ‘new_var’ is the variable name and ‘hey’ is the value assigned to it.

3. varible_del(name): If you wish to delete a variable, you call this function. It deletes the variable, taking its name into consideration. For example, variable_del(new_var)- calling this function will delete the variable named as ‘new_var’.

These are the variable functions that help you in setting, getting and deleting the various variables in a Drupal module. You can learn more about these functions once you use them on the practical front.

Drupal module development requires a professional insight and thus can be a tedious job at times. You need to be well versed with Drupal and the development strategies in general, in order to perform the right module development. You can also plan and hire Drupal programmer who has expertise in the field, so that he can assist you in the entire process and make it simplified.
