Having A Relationship

Having a relationship is nothing easy. It takes time, commitment, lot of moneys and sometimes lots of chocolate to feel loved if you are being neglected.

Thankfully in ProdigyView all you need to have is more than one user and you can define a relationship between them. We will be covering in tutorial:

Add Some UsersOur example starts by first creating some users. If you are following along in the code example, there are two more users created besides the two below.

Creating A RelationshipNow that we have our users present in the database, we can start creating relationships. It takes two to make this thing go right, so we at least require two users, a relationship type, and relationship status.

1. Add the first user 2. Add the second user

3. Set the relationship type4. Add the relationship status. Meaning of numbers is set by you. Example '1 could be ‘accepted’ and 0 mean ‘pending’.

Database ViewYour database should look something like after adding the users.

Searching RelationshipsNext we can search through our relationship using getUserRelationshipList() method. The method uses PV Standard Search arguments when querying for matches.

1. Search for users based on the requesting users field

2. The ‘,’ symbolizes an OR used in SQL

3. Returns the relationships as an array of arrays

Compare RelationshipsSince we are pulling out our users, lets do some comparisons using the checkUserRelationship(). This method checks if there is an relationship among users. Explanation on next slide.

Comparison Explanation1. Iterate through the relationships

2. Get the users information based on their user_id in the relationship

3. Print out the found relationship type 4. Check is there is any relationship based on the two users ids

5. Results on next slide

The Comparison ResultsIf they are suppose be a family, something is definitely off.

Removing A RelationshipObviously the relationships were not quite working out so it’s time for everyone to go there separate ways. I guess that means it’s time to delete some relationships.

Delete the relationship by passing in the relationship id
