# B2bContextTrait

**What are PHP Traits?**

Since PHP 5.4.0, there is a method of reusing code in PHP called traits. Traits is a mechanism for reusing code that is used in programming languages with simple inheritance such as PHP.

**Why is the B2bContextTrait useful for your individual extension?**

With the B2bContextTrait you can make in your PHP Code a simple function to distinguish the customer ("Customers"). Is the logged-in customer an end customer, an employee/user of a customer or is he a sales employee, you can also query whether the sales employee is currently logged into an end customer.

What are the possible functions:

| Function                                | Description                                                                                                                         |

| getEmployee                             | Return of all employee fields (type: EmployeeEntity)                                                                                |
| isSalesRepresentativeLoggedInAsCustomer | Is a sales employee currently logged into a customer employee.                                                                      |
| customerIsSalesRepresentative           | Always returns true: when you are logged in as a sales agent and when you are logged in to a customer as a sales agent              |

How can you use our B2bContextTrait in your Shopware extension?

With the "use" function you can add the trait to any PHP class...

<div align="left"><img src="https://content.gitbook.com/content/xtXbbs1TkvdlT98tybg5/blobs/lFrhkUWxveqAncvnaBAP/111.png" alt=""></div>

And then call the classes from the trait via $this->\[function-name].
