To define options of the select item you should use SelectOptionsConnector on the server-side and specify the connector parameter for the appropriate item on client-side:

client-side:

var formData = [{type: "select", label: "Categories", connector:"selectOptions.php"}];

server-side:

<?php 
require_once("../codebase/connector/options_connector.php");
$res=mysql_connect("localhost","root","");
mysql_select_db("myDB");
 
$data = new SelectOptionsConnector($res, "MySQL");
$data->render_table("categories","id","valueColumn, labelColumn");
 
?>

For more information of this topic, see 'SelectOptionsConnector' article.

To define options of the 'combo' item you should use ComboConnector on the server-side and specify the connector parameter for the appropriate item on client-side:

client-side:

var formData = [{type: "combo", name: "myCombo", label: "Select type", connector:"comboOptions.php"}];

server-side:

<?php 
require_once("../codebase/connector/combo_connector.php");
$res=mysql_connect("localhost","root","");
mysql_select_db("myDB");
 
$data = new ComboConnector($res, "MySQL");
$data->render_table("categories","id","valueColumn, labelColumn");
?>

• Names of the fields can have aliases (value or label) to identify the appropriate attribute.
  
  

  $data->render_sql("SELECT *, CONCAT(FirstName, LastName) as label FROM table1","id","id,FirstName(label)");

  Note, in the filtering mode a combo filters data by the “label” field.

To load data to a form you should use FormConnector on server-side and the method load (id) on client_side:

client-side

myForm.load('formdata.php?id=1');

where as the parameter must be specified a connector file with the id of loading record.
Values of record's columns will be used as values of form's controls.

server-side

<?php 
require_once("../codebase/connector/form_connector.php");// includes the appropriate connector 
$res=mysql_connect("localhost","root","");//connects to a server that contains the desired DB
mysql_select_db("tasks");// connects to the DB. 'tasks' is the name of our DB
$conn = new FormConnector($res,"MySQL");// connector initialization
$conn->render_table("customers","id","name, address, email");// data configuration 
?>

To save form changes to DB, you should use the method save() on client-side.
You can call this method, for example, on clicks of some button.

myForm.attachEvent("onButtonClick", function(id){
        if (id=='saveButton'){
                myForm.save();
        }
}
