Do you want to add a user to an organic group programmatically in Drupal, then here is a solution. In one of my Drupal module I had a requirement to add users programmatically to an organic group. So I have created a custom function in my module for this purpose. This uses the function og_group to add a user entity to a group. Refer the following code. Remember that, you can add only an existing user to a group. It will not create a new user.

If you want to display some custom text related to an entity (which are not part of the entities fields. Eg. Calculated sum based on some values of the fields) in your apache solr search result, you can do it in two simple steps.

In Drupal 6, the configuration of vocabulary itself has an option to specify the content types that requires this vocabulary. There is only global settings for the vocabulary. If we set the vocabulary as multiple select, it will apply to all of the content types to which it belongs. We can not set this field as multiple select in one content type and single select in others.

I have a vocabulary in my drupal project and I want to make the vocabulary as a single select in one of my content types. I can do it in the form_alter. But to select the vocabulary item in the form_alter, I need its vocabulary-id. I dont want to hard code vocabulary-id in my code, so I searched for a drupal core function to get the vocabulary id from its name. In drupal 7 there is a function to get the entire vocabulary object from its machine name. But in drupal 6 there is no core function to get vocabulary id from its name. So I created a custom function to get the vocabulary id from its name. See the following function I programmed, to get the vocabulary id from its name.

Drupal 6 will not allow you to create multiple access callbacks for a menu. In hook menu, the access callback will accept only string value, not an array. But I had a requirement in my project to add a custom access callback without removing the existing access callback. My custom access callback should be executed first. After that if some condition satisfies in my custom function the original access callback should get executed.

There are situations where we need organic groups membership entity ID. Some of situations are : we use the function og_membership_delete() when we want to remove programmatically a user or node or any group content from our group, which will require parameter that is organic groups membership entity ID. Also when come across og_membership_load() function to get the entire organic groups membership object, which will also require OG membership entity ID as parameter. So in these situations how can we get organic groups membership object membership entity ID. See the following function I have written to retrieve the organic groups membership object membership entity Id.
