buildFooter bool Whether to build the footer. true
buildHeader bool Whether to build the header. true
classASC string A CSS class name for TH elements to define that sorting is currently ascending. ''
classDESC string A CSS class name for TH elements to define that sorting is currently descending. ''
columnAttributes array Column cells attributes. This is an array of the form: array(fieldName => array(attribute => value, ...) ...) This option is only used by XML/HTML based drivers. array()
convertEntities bool Whether or not to convert html entities. This calls htmlspecialchars(). true
defaultCellValue string What value to put by default into empty cells. null
defaultColumnValues array Per-column default cell value. This is an array of the form: array(fieldName => value, ...). array()
emptyRowAttributes array An associative array containing the attributes for empty rows. array()
encoding string The content encoding. If the mbstring extension is present the default value is set from mb_internal_encoding(), otherwise it is ISO-8859-1. 'ISO-8859-1'
evenRowAttributes array An associative array containing each attribute of the even rows. array()
excludeVars array Variables to be removed from the generated HTTP queries. array()
extraVars array Variables to be added to the generated HTTP queries. array()
fillWithEmptyRows bool Ensures that all pages have the same number of rows. false
headerAttributes array Attributes for the header row. This is an array of the form: array(attribute => value, ...) array()
hideColumnLinks array By default sorting links are enabled on all columns. With this option it is possible to disable sorting links on specific columns. This is an array of the form: array(fieldName, ...). This option only affects drivers that support sorting. array()
numberAlign bool Whether to right-align numeric values. true
oddRowAttributes array An associative array containing each attribute of the odd rows. array()
onMove string Name of a Javascript function to call on onclick/onsubmit events when the user is either paging or sorting the data. This function receives a single object argument of the form: { page: <page>, sort: [{field: <field>, direction: <direction>}, ...], data: <user_data> }. Remark: setting this option doesn't remove the href attribute, you should return false from your handler function to void it (eg: for AJAX, etc..). null
onMoveData string User data passed in the "data" member of the object argument passed to onMove. No JSON serialization is performed, this is assigned as a raw string to the "data" attribute. It's up to you to add quotes, slashes, etc... ''
selfPath string The complete path for sorting and paging links. $_SERVER['PHP_SELF']
sortIconASC string The icon to define that sorting is currently ascending. Can be text or HTML to define an image. ''

Examples

Simple AJAX support using the Prototype framework

<?php
require_once 'PEAR.php';
require_once 
'Structures/DataGrid.php';    

$datagrid =& new Structures_DataGrid(10);

$options['dsn'] = 'mysql://username@localhost/mydatabase';
$datagrid->bind("SELECT * FROM mytable"$options);

// Set the javascript handler function for onclick events
$datagrid->setRendererOption('onMove''updateGrid'true);

if (isset(
$_GET['ajax'])) {
    
// Handle table AJAX requests 
    
if ($_GET['ajax'] == 'table') {
        
$datagrid->render();
    }
    
// Handle pager AJAX requests 
    
if ($_GET['ajax'] == 'pager') {
        
$datagrid->render('Pager');
    }
    exit();
}

// No AJAX request, render the initial content..
?>
