## Example Implementation

<pre><code><strong>var playerInfo = {
</strong><strong>    ip: "155.34.22.11",
</strong><strong>    location : "Ontario"
</strong><strong>}
</strong><strong>var name = get_string("Whats your name?","Name");  ///user replies lilshake
</strong><strong>var writeId = SetSimpleData("users", "name", playerInfo)
</strong></code></pre>

This requests the server to create this struct as a document with name "lilshake"

the **callback\_SetSimpleData()** actually gives the confirmation of the write.
