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
form object Instance of a HTML_QuickForm object. null
formRenderer object Instance of a HTML_QuickForm_Renderer_QuickHtml object. null
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()
inputName string The HTML_QuickForm element name for the checkboxes. 'checkedItems'
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... ''
primaryKey string The name of the primary key. This value is used for the checkboxes. 'id'
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. ''
sortIconDESC string The icon to define that sorting is currently descending. Can be text or HTML to define an image. ''
sortingResetsPaging bool Whether sorting HTTP queries reset paging. true

General notes

This driver puts a checkbox for each row of the table into the first column. By default, a new column with the value of the 'inputName' option is added for the checkboxes. If you want to customize this column, you can add a column yourself as it is shown in the example.

Examples

Basic usage

<?php
require_once 'HTML/QuickForm.php';
require_once 
'HTML/QuickForm/Renderer/QuickHtml.php';
require_once 
'Structures/DataGrid.php';

// prepare the form and the QuickHtml renderer
$form =& new HTML_QuickForm();
$renderer =& new HTML_QuickForm_Renderer_QuickHtml();

// add action selectbox and submit button to the form
$form->addElement('select''action''choose',
                  array(
'delete' => 'Delete',
                        
'move'   => 'Move to archive'));
$form->addElement('submit''submit''Save');

// prepare the DataGrid
$dg =& new Structures_DataGrid();
if (
PEAR::isError($dg)) {
   die(
$dg->getMessage() . '<br />' $dg->getDebugInfo());
}

// bind some data (e.g. via a SQL query and MDB2)
$error $dg->bind('SELECT * FROM news',
                   array(
'dsn' => 'mysql://user:password@server/database'));
if (
PEAR::isError($error)) {
   die(
$error->getMessage() . '<br />' $error->getDebugInfo());
}

// the renderer adds an auto-generated column for the checkbox by default;
// it is also possible to add a column yourself, for example like in the
// following four lines:
$column = new Structures_DataGrid_Column('checkboxes''idList'null,
                                         array(
'width' => '10'));
$dg->addColumn($column);
$dg->generateColumns();

$rendererOptions = array('form'         => $form,
                         
'formRenderer' => $renderer,
                         
'inputName'    => 'idList',
                         
'primaryKey'   => 'id'
                        
);

// use a template string for the form
$tpl '';

// generate the HTML table and add it to the template string
$tpl .= $dg->getOutput('CheckableHTMLTable'$rendererOptions);
if (
PEAR::isError($tpl)) {
   die(
$tpl->getMessage() . '<br />' $tpl->getDebugInfo());
}

// add the HTML code of the action selectbox and the submit button to the
// template string
$tpl .= $renderer->elementToHtml('action');
$tpl .= $renderer->elementToHtml('submit');

// we're now ready to output the form (toHtml() adds the <form> / </form>
// pair to the template)
echo $renderer->toHtml($tpl);

// if the form was submitted and the data is valid, show the submitted data
if ($form->isSubmitted() && $form->validate()) {
    
var_dump($form->getSubmitValues());
}
