Getting Started
The Basics
There are two ways to bind a Kendo UI MultiSelect for PHP:
- Locally—Local binding binds the MultiSelect to a PHP array.
- Remotely—During remote binding the MultiSelect 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 MultiSelect 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 MultiSelect will be bound.
<?php
$data = array(
array('name' => 'John Doe', 'age' => 32),
array('name' => 'Jane Doe', 'age' => 29),
array('name' => 'Jane Doe', 'age' => 27)
);
?>
Step 3 Create a data source and set its data.
<?php
$dataSource = new \Kendo\Data\DataSource();
$dataSource->data($data);
?>
Step 4 Create a MultiSelect.
<?php
$dataSource = new \Kendo\Data\DataSource();
$dataSource->data($data);
$multiSelect = new \Kendo\UI\MultiSelect('MultiSelect');
$multiSelect->dataSource($dataSource);
$multiSelect->dataTextField('name');
$multiSelect->dataValueField('age');
$multiSelect->value(array(27, 29));
?>
Step 5 Output the MultiSelect by echoing the result of the render method.
<?php
echo $multiSelect->render();
?>
Value Pre-Selection on Initial Loading
When deferred binding (autoBind: false) is used, you need to specify a list of data items instead of just a list of strings. This functionality is first supported in Kendo UI Q1 SP1 2013 release and all later versions.
<?php
$dataSource = new \Kendo\Data\DataSource();
$dataSource->data($data);
$multiSelect = new \Kendo\UI\MultiSelect('MultiSelect');
$multiSelect->dataSource($dataSource);
$multiSelect->dataTextField('name');
$multiSelect->dataValueField('age');
$multiSelect->autoBind(false);
$multiSelect->value(array(
array('name' => 'John Doe', 'age' => 32),
array('name' => 'Jane Doe', 'age' => 29)
));
?>
Event Handling
You can subscribe to all MultiSelect events.
Specify Function Names
The example below demonstrates how to subscribe for events by specifying a JavaScript function name.
<?php
$multiSelect = new \Kendo\UI\MultiSelect('multiselect');
// The 'multiselect_change' JavaScript function will handle the 'change' event of the multiselect
$multiSelect->change('multiselect_change');
echo $multiSelect->render();
?>
<script>
function multiselect_change() {
// Handle the change event
}
</script>
Provide Inline Code
The example below demonstrates how to provide inline JavaScript code.
<?php
$multiSelect = new \Kendo\UI\MultiSelect('multiselect');
// Provide inline JavaScript code that will handle the 'change' event of the multiselect
$multiSelect->change('function() { /* Handle the change event */ }');
echo $multiSelect->render();
?>
Reference
Client-Side Instances
You can reference the client-side Kendo UI MultiSelect instance via jQuery.data(). Once a reference is established, use the MultiSelect API to control its behavior.
<?php
$multiSelect = new \Kendo\UI\MultiSelect('multiselect');
echo $multiSelect->render();
?>
<script>
$(function() {
// The constructor parameter is used as the 'id' HTML attribute of the multiselect
var multiselect = $("#multiselect").data("kendoMultiSelect")
});
</script>
