ComboBox PHP Class Overview
The Kendo UI ComboBox for PHP is a server-side wrapper for the Kendo UI ComboBox widget.
Getting Started
The Basics
There are two ways to bind a Kendo UI ComboBox for PHP:
- Locally—Local binding binds the ComboBox to a PHP array.
- Remotely—During remote binding the ComboBox makes AJAX requests and is bound to the JSON result.
Configuration
Below are listed the steps for you to follow when configuring the Kendo UI ComboBox for local binding.
Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for PHP—include the autoloader, JavaScript, and CSS files.
Step 2 Create an array to which the ComboBox will be bound.
<?php
$data = array(
array('name' => 'John Doe', 'age' => 32),
array('name' => 'Jane Doe', 'age' => 29)
);
?>
Step 3 Create a data source and set its data
.
<?php
$dataSource = new \Kendo\Data\DataSource();
$dataSource->data($data);
?>
Step 4 Create an ComboBox, configure its dataTextField
dataValueField
options and set its DataSource
.
<?php
$dataSource = new \Kendo\Data\DataSource();
$dataSource->data($data);
$comboBox = new \Kendo\UI\ComboBox('ComboBox');
$comboBox->dataSource($dataSource);
$comboBox->dataTextField('name');
$comboBox->dataValueField('age');
?>
Step 5 Output the ComboBox by echoing the result of the render
method.
<?php
echo $comboBox->render();
?>
Event Handling
You can subscribe to all ComboBox events.
Specify Function Names
The example below demonstrates how to subscribe for events by specifying a JavaScript function name.
<?php
$comboBox = new \Kendo\UI\ComboBox('combobox');
// The 'combobox_change' JavaScript function will handle the 'change' event of the combobox
$comboBox->change('combobox_change');
echo $comboBox->render();
?>
<script>
function combobox_change() {
// Handle the change event
}
</script>
Provide Inline Code
The example below demonstrates how to provide inline JavaScript code.
<?php
$comboBox = new \Kendo\UI\ComboBox('combobox');
// Provide inline JavaScript code that will handle the 'change' event of the combobox
$comboBox->change('function() { /* Handle the change event */ }');
echo $comboBox->render();
?>
Reference
Client-Side Instances
You can reference the client-side Kendo UI ComboBox instance via jQuery.data()
. Once a reference is established, use the ComboBox API to control its behavior.
<?php
$comboBox = new \Kendo\UI\ComboBox('combobox');
echo $comboBox->render();
?>
<script>
$(function() {
// The constructor parameter is used as the 'id' HTML attribute of the combobox
var combobox = $("#combobox").data("kendoComboBox")
});
</script>
