Structures_DataGrid_Renderer_HTMLSortForm – Multiple fields sorting form rendering driver
This driver renders a form (using HTML_QuickForm) so that the user can select several fields and directions to sort the datagrid by.
Supported operations modes
This driver supports the following operation modes:
| Mode | Supported? |
|---|---|
| Container Support | yes |
| Output Buffering | yes |
| Direct Rendering | no |
| Streaming | no |
| Object Preserving | no |
Options
This driver accepts the following options:
| Option | Type | Description | Default Value |
|---|---|---|---|
| buildFooter | bool | Whether to build the footer. | true |
| buildHeader | bool | Whether to build the header. | 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() |
| directionStyle | string | Whether to render the direction form elements as 'select' or 'radio' elements | 'select' |
| 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' |
| 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 |
| 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 |
| 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... | '' |
| sortFieldsNum | int | How many fields the user will be able to sort by. This has no effect if the backend does not support sorting by multiple fields. | 3 |
| textAscending | string | Label for the ASC direction | 'Ascending' |
| textChoose | string | What to display in the select box when no field is selected (first option) | 'Choose...' |
| textDescending | string | Label for the DESC direction | 'Descending' |
| textSortBy | string | Label for the first field | 'Sort by:' |
| textSubmit | string | Label for the submit button | 'Submit' |
| textThenBy | string | Label for the second and following fields | 'Then by:' |
Examples
Fill a form with sort fields
<?php
require_once 'HTML/QuickForm.php';
// Create an empty form with your settings
$form = new HTML_QuickForm('myForm', 'POST');
// Customize it, add a header, text field, etc..
$form->addElement('header', null, 'Search & Sort Form Example');
$form->addElement('text', 'my_search', 'Search for:');
// Let the datagrid add sort fields, radio style
$options = array('directionStyle' => 'radio');
$datagrid->fill($form, $options, 'HTMLSortForm');
// You must add a submit button. fill() never does this
$form->addElement('submit', null, 'Submit');
// Use the native HTML_QuickForm::display() to print your form
$form->display();
